Chapter 1

Overview

This chapter gives an overview of the 4 ports desktop version VoIP Gateway Router (TVP224HR) and a detailed description of its front panel and rear panel.

Congratulations on the purchase of your new TVP-224HR. The TVP-224HR is a multifunction device providing the following services:

Shared Broadband Internet Access for all LAN users.

Figure 1: TVP-224HR

1.1 Features

The TVP-224HR is a cost-effective and highly reliable analog Voice over IP (VoIP) Gateway Router that offers toll quality voice and real-time fax data over IP networks. With its embedded architecture, the gateway is ideal for VoIP applications associated with Remote Office and Branch Office (ROBO) environments. With its built-in user-friendly interface, the gateway may be installed easily and conveniently to yield immediate cost savings. One VoIP Gateway supports up to four voice or Fax communications simultaneously.

Implemented with an efficient Real-Time Operating System (RTOS) and flash memory, the TVP-224HR provides upgradeable capabilities, so it may be programmed with updated firmware locally or via the network at any time. It comes equipped with remote management capabilities, configurable signaling to work with PBX, KTS, and/or telephone. The TVP-224HR utilizes advanced VoIP related technology. It includes various voice codecs and fax algorithms, echo cancellation, Voice Activity Detection (VAD), Comfort Noise Generation (CNG), and lost packet recovery algorithms.

Internet Access Features

• Shared Internet Access. All users on the LAN or WLAN can access the Internet through the TVP-224HR, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation).
• DSL & Cable Modem Support. The TVP-224HR has a 100BaseT Ethernet port for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are supported. SingTel RAS and Big Pond (Australia) login support is also included.
• PPPoE. The Internet (WAN port) connection supports PPPoE (PPP over Ethernet).
• Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the TVP-224HR supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address.

Advanced Internet Functions

• Special Internet Applications. Applications which use non-standard connections or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally.
• Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy.
• DMZ. One (1) PC on your local LAN can be configured to allow unrestricted 2-way communication with Servers or individual users on the Internet. This provides the ability to run programs which are incompatible with Firewalls.
• QoS. This feature "guarantees" better service to selected traffic on a network. The goal in configuring QoS is to give priority and attention to certain devices or services so that they can use the maximum available throughput and speed available on a certain network when it is needed.

LAN Features

• DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The TVP-224HR can act as a DHCP Server for devices on your local LAN and WLAN.

Configuration & Management

• Easy Setup. Use your WEB browser from anywhere on the LAN or WAN for configuration.
• Remote Management. The TVP-224HR can be managed from any PC on your LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet using a web browser or telnet.

Security Features

• Password - protected Configuration. password protection is provided to prevent unauthorized users from modifying the configuration data and settings.
• NAT Protection. An intrinsic side effect of NAT (Network Address Translation) technology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the TVP-224HR.

1.2 Networking Protocols

The TVP-224HR supports several industry-standard networking protocols required for voice communication. The following table describes these protocols.

Networking Protocol	Description
Internet Protocol (IP)	IP is a messaging protocol that addresses and sends packets across the network. To enable IP protocol, the TVP-224HR must have a Real IP address, subnet, and gateway assigned to it.
Voice over IP Protocol (VoIP)	VoIP enables the TVP-224HR to transfer voice communications over an IP network. The TVP-224HR employs ITU-T H.323 protocol for setting up calls with one another.
Trivial File Transfer Protocol (TFTP)	TFTP allows you to transfer files over the network. The TVP-224HR implements a TFTP client allowing you to download new revision firmware from a TFTP server. The TFTP client requires a TFTP server in your network.
Real-Time Transport (RTP)	RTP is a standard for transporting real-time data over IP network. The TVP-224HR uses RTP protocol to send digitized and compressed voice packets.

Chapter 2

Installing the TVP-224HR

This chapter gives information on how to install the TVP-224HR.

2.1 Network Requirements

For the TVP-224HR to successfully operate in your network, your network must meet the following requirements:

1. A working 10/100 Base-T Ethernet. The TVP-224HR connects to the Internet via an Ethernet LAN.
2. IP network that supports gateway, and subnet mask. You'll need a static IP address to assign the TVP-224HR or a DDNS account for your Dynamic IP.

2.2 Installing the TVP-224HR

Due to the TVP-224HR being used in a desktop configuration, ensure that the TVP-224HR is placed in a clean, well-ventilated, and vibration-free environment.

When the TVP-224HR is used, be certain that the unit is placed on a sturdy, flat surface, near a grounded power outlet. At least three inches of clearance must be provided on both sides of the TVP-224HR for good ventilation.

2.3 Connecting to the telephony devices

The 4 port TVP-224HR supports 2 FXO and 2 FXS. Each RJ11 port is for connecting to telephony devices.

The FXO port is designed for connecting to PBXs or local telephone company central office switches (CO).

The FXS port is designed for connecting to analog telephone sets, G3 fax machines.

Warning: connection of incorrect telephony devices to the ports on the TIM can cause permanent damage to the TIM and/or the TVP-224HR.

2.4 Connecting to the LAN Network

The 4x RJ45 LAN network ports on the rear panel supports 10/100 Mbps half-duplex connections to Ethernet. You can use either Category 3 or 5 straight-through UTP cable for 10 Mbps connections, but use Category 5 for 100 Mbps connections. Insert one end of the Ethernet cable into one of the 4 RJ45 ports on the rear panel of the TVP-224HR and other end of the cable to a network device / PC.

2.5 Assigning an IP address to the TVP-224HR

The IP address is the unique logical address identifying each IP node, such as the TVP-224HR, on an IP network. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 255 separated by periods. The TVP-224HR can be configured with a fixed IP address, subnet mask and default gateway. The TVP-224HR can also be setup as a DHCP. Additionally, the TVP-224HR can also be configured to use PPPoE. With PPPoE, you will have a Dynamic IP but combined with Dynamic DNS, the TVP-224HR will automatically notify DynDNS of your changing IP Address and DynDNS will in turn, map it to your registered Domain Name. Consult your network manager to obtain a unique and static IP address for the TVP-224HR, the IP subnet mask and default gateway of your network, and fill out the work sheet in Appendix D before configuring the gateway. Procedures for assigning IP address, default gateway and subnet mask is available in Chapter 4.

2.6 Hardware Installation Procedures

• Netscape V4.08 or later
• Internet Explorer V4 or later

Preparation

Before attempting to configure the TVP-224HR, please ensure that:

• Your PC can establish a physical connection to the TVP-224HR. The PC and the TVP-224HR must be directly connected (using the Hub ports on the TVP-224HR) or on the same LAN segment.
  The TVP-224HR must be installed and powered ON.
• If the TVP-224HR's default IP Address (192.168.0.1) is already used by another device, the other device must be turned OFF until the TVP-224HR is allocated a new IP Address during configuration.

Using your Web Browser

To establish a connection from your PC to the TVP-224HR:

1. After installing the TVP-224HR in your LAN, start your PC. If your PC is already running, restart it.
2. Start your WEB browser.
3. In the Address box, enter "HTTP://" and the IP Address of the TVP-224HR, as in this example, which uses the TVP-224HR's default IP Address:

HTTP://192.168.0.1

If you can't connect

If the TVP-224HR does not respond, check the following:

The TVP-224HR is properly installed, LAN connection is OK, and it is powered ON. You can test the connection by using the "Ping" command:

• Open the MS-DOS window or command prompt window.
  Enter the command: ping 192.168.0.1

If no response is received, either the connection is not working, or your PC's IP address is not compatible with the TVP-224HR 's IP Address. (See next item.)

If your PC is using a fixed IP Address, its IP Address must be within the range 192.168.0.2 to 192.168.0.254 to be compatible with the TVP-224HR's default IP Address of 192.168.0.1. Also, the Network Mask must be set to 255.255.255.0. See Chapter 4 - PC Configuration for details on checking your PC's TCP/IP settings.

Ensure that your PC and the TVP-224HR are on the same network segment. (If you don't have a router, this must be the case.)

TCP/IP
IP Address	IP address for the TVP-224HR, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN.
Subnet Mask	The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which the TVP-224HR is attached (the same value as the PCs on that LAN segment).
DHCP Server	DHCP Server is by default, always on. The TVP-224HR will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be re-configured to treat the TVP-224HR as the default Gateway. See the following section for further details. The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. See the following section for further details on using DHCP.

DHCP

What does DHCP do?

A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request.

• The client request is made when the client device starts up (boots).
• The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address.
  The TVP-224HR can act as a DHCP server.
• Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client. This is the default Windows setting for the TCP/IP network protocol.

However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client".

• You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.)

Using the TVP-224HR's DHCP Server

This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can:

• Enable or Disable the TVP-224HR's DHCP Server function. Disable the DHCP by entering "0" in the number of clients field
• Set the range of IP Addresses allocated to PCs by the DHCP Server function.

You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server.

Using another DHCP Server

You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the TVP-224HR 's, the following procedure is required.

1. Disable the DHCP Server feature in the TVP-224HR. Disable the DHCP by entering "0" in the number of clients field.
2. Configure the DHCP Server to provide the TVP-224HR's IP Address as the Default Gateway.

To Configure your PCs to use DHCP

This is the default setting for TCP/IP under Windows 95/98/ME.

See Chapter 4 - Client Configuration for the procedure to check these settings.

Overview

For each PC, the following may need to be configured:

• TCP/IP network settings
• Internet Access configuration

Windows Clients

This section describes how to configure Windows clients for Internet access via the TVP-224HR.

The first step is to check the PC's TCP/IP settings.

The TVP-224HR uses the TCP/IP network protocol for all functions, so it is essential that the TCP/IP protocol be installed and configured on each PC.

TCP/IP Settings - Overview

If using the default TVP-224HR settings, and the default Windows TCP/IP settings, no changes need to be made.

• By default, the TVP-224HR will act as a DHCP Server, automatically providing a suitable IP Address (and related information) to each PC when the PC boots.
• For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP client.

If using a Fixed (specified) IP address, the following changes are required:

The Gateway must be set to the IP address of the TVP-224HR
- The DNS should be set to the address provided by your ISP.

Do to NAT resolution issues, it is not recommended to use the TVP-224HR under another Router.

Checking TCP/IP Settings - Windows 9x/ME:

1. Select Control Panel - Network. You should see a screen like the following:

Figure 5: Network Configuration

1. Select the TCP/IP protocol for your network card.
2. Click on the Properties button. You should then see a screen like the following.

Special Applications

If you use Internet applications which use non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the TVP-224HR 's firewall. In this case, you can define the application as a "Special Application".

Special Applications Screen

This screen can be reached by clicking the Special Applications submenu located under the Router Configuration main menu.

You can then define your Special Applications. You will need detailed information about the application; this is normally available from the supplier of the application. You can also reference the Common Port Setting page.

Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the client (PC) viewpoint

TVP-224HR VoIP Gateway Router

Special APP Setup

Figure 21: Special Applications Screen

Data - Special Applications Screen

Checkbox Description Incoming Ports No

Use this to Enable or Disable this Special Application as required.

Enter a descriptive name to identify this Special Application.

Type - Select the protocol (TCP or UDP) used when you receive data from the special application or service. (Note: Some applications use different protocols for outgoing and incoming data).

From - Enter the beginning of the range of port numbers used by the application server, for data you receive. If the application uses a single port number, enter it in both the "From" and "to" fields.

To - Enter the end of the range of port numbers used by the application server, for data you receive.

Outgoing Ports

Type - Select the protocol (TCP or UDP) used when you send data to the remote system or service.

From - Enter the beginning of the range of port numbers used by the application server, for data you send to it. If the application uses a single port number, enter it in both the "From" and "To" fields.

To - Enter the end of the range of port numbers used by the application server, for data you send to it. If the application uses a single port number, enter it in both the "From" and "To" fields.

Using a Special Application

• Configure the Special Applications screen as required.
• On your PC, use the application normally. Remember that only one (1) PC can use each Special application at any time. Also, when 1 PC is finished using a particular Special Application, there may need to be a "Time-out" before another PC can use the same Special Application. The "Time-out" period may be up to 3 minutes.

If an application still cannot function correctly, try using the "DMZ" feature.

DMZ

This feature, if enabled, allows one (1) device /

PC on your LAN to be exposed to all users on the

Internet.

This allows unrestricted 2-way communication between the "DMZ PC" and other Internet users or Servers.

This allows almost any application to be used on the "DMZ PC".
- The "DMZ PC" will receive all "Unknown" connections and data.
- If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".

The "DMZ PC" is effectively outside the Firewall, making it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required.

Dynamic DNS (Domain Name Server)

This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect, which makes it difficult to connect to you.

The Service works as follows:

1. You must register for the service at www.dyndns.org using the dyndns.org domain.

2. After registration, follow the Service Provider's procedure to request a Domain Name, and have it allocated to you.

3. Enter your DDNS data on the TVP-224HR's DDNS screen (shown below).

4. The TVP-224HR will then automatically ensure that your current IP Address is recorded and updated at the DDNS server.

If the DDNS Service provides software to perform this "IP address update"; you should disable the "Update" function, or not use the software at all.

1. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using your Domain name, as shown on this screen.

Dynamic DNS Screen

Select Internet on the main menu, then Dynamic DNS, to see a screen like the following:

Figure 22: DDNS Screen

Data - Dynamic DNS Screen

DDNS Service
DDNS Service	You must register for the service at dyndns.org. Apply for a Domain Name, and ensure it is allocated to you. Details of your DDNS account (Name, password, Domain name) must then be entered and saved on this screen. This device will then automatically ensure that your current IP Address is recorded by the DDNS Service Provider. (You do NOT need to use the "Client" program provided by some DDNS Service providers.)
	From the Internet, users will now be able to connect to your Virtual Servers (or DMZ PC) using your Domain name.

DDNS Data
Dyn DNS	On/Off
User Name	Enter yourUsername for the DDNS Service.
Password/Key	Enter your current password for the DDNS Service.
Domain Name (Hostname)	Enter the domain (hostname) name registered at www.dyndns.org. For instance, if you registered johnsmith.dyndns.org, please enter
	johnsmith
DDNS Status	This message is returned by the DDNS Server Normally, this message should be something like "Update successful" or "IP address updated". If the message indicates some problem, you need to connect to the DDNS Service provider and correct this problem.

Virtual Servers / Port Forwarding

This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because:

• Your Server does not have a valid external IP Address.
• Attempts to connect to devices on your LAN are blocked by the firewall in this device.

The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below.

Figure 23: Virtual Servers

IP Address seen by Internet Users

Note that, in this illustration, both Internet users are connecting to the same IP Address, but using different protocols.

To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP.

This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your Virtual Servers using a URL, instead of an IP Address.

Virtual Servers Screen

The Virtual Servers screen is reached by the Virtual Servers link under the Router Configuration menu. An example screen is shown below.

Internal IP	Enter the IP Address of the virtual server. The PC must be running the appropriate Server software.
Internal Port	Enter the port number used by the virtual server

Connecting to the Virtual Servers

Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP).

e.g.

http://203.70.212.52

ftp://203.70.212.52

It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature, described in the following section, to allow users to connect to your Virtual Servers using a URL, rather than an IP Address.

Voice QoS

QoS is a popular feature that "guarantees" better service to selected traffic on a network. The goal in configuring QoS is to give priority and attention to certain devices or services so that they can use the maximum available throughput and speed available on a certain network when it is needed.

Voice QoS Screen

The Voice QoS screen is reached by the Voice QoS link under the Router Configuration menu. An example screen is shown below

Assured Bandwidth for Voice	Enter the amount of bandwidth you would like to reserve for VoIP packets. To determine how much bandwidth you will require, multiply the number of potential simultaneous connections (channels / ports) by the current codec you are implementing.G.711 PCM 64kbps + Packet Header information = 80±5 KbpsG.723.1A (5.3, 6.3kbps) + Packet Header information = 10kbps ±2 kbpsG.729AB (8kbps) = 12 ±4 kbpsDefault codec is G.729AB. Therefore, if all FXO and FXS ports are being used, (4 Ports) multiplied by the default compression codec G.729AB at 16kbps would yield roughly 72kbps.
Maximum Uplink Bandwidth allowed (kbits/sec)	In the Field you will first have to find your ISP's speed in your contract or on the ISP's webpage. The values for speed are usually given in kilo Bits per second [kb/s] as are the values to be entered into TVP-224HR. If you are given you Maximum Uplink Bandwidth in KB/s, To convert to kilo Bytes simply multiply the kilo Bytes by a value of 8 Example: Maximum Downstream: 96kB/s x 8 = 768kb/s Maximum Upstream: 16kB/S x 8 = 128kb/s

Chapter 8

TVP-224HR Telephony

Concepts

The TVP-224HR enables the transmission of voice and fax traffic over any IP network by digitizing voice and fax signals, encapsulating the information within IP packets, and then sending the packets across the IP network

8.1 How the TVP-224HR Operates

1. The TIM inside the TVP-224HR digitizes analog voice signals at 8 Kbps.

2. TVP-224HR system software handles the:

3. Capture of telephone number presented as DTMF tones.

4. Mapping the telephone number to the IP address of remote VoIP Gateway.
5. Setting up calls with remote TVP-224HRs utilizing H.323 call control protocol.

6. Digitizing, compressing and encapsulating the voice into IP packets and transmission of the IP packets onto the Ethernet LAN.

7. The TVP-224HR router forwards the IP packets across the WAN, where they will be received by another VoIP Gateway at the remote.

8. The process is reversed at the remote VoIP Gateway.

8.2 ATPM

To allow you to easily dial a telephone or fax on the network, the TVP-224HR maps a series of dialed digits to the IP address of the remote TVP-224HR whose phone or fax you are calling. This mapping information is contained in a database inside each TVP-224HR called the dial plan.

Based on the dial plan, the Address Translation and Parsing Manager (ATPM) inside the TVP-224HR maps telephony numbers to IP addresses of remote VoIP Gateways. The ATPM collects telephone number dialed by users, decides whether the dial string is part of the dial plan and, if it is, maps it to a remote TVP-224HR / TVP-224HR. When the call is set up to the destination, a sub-string of the original dial string will be sent along to the remote VoIP Gateway.

8.3 Destination

The destination is where a call is terminated. Typically, for inbound calls from the IP network, the TVP-224HR terminals the call at one of the telephony ports. The

destination for the call is the telephony port where the call terminated. For calls initiated from telephony ports, the TVP-224HR forwards the call to a remote TVP-224HR/TVP-224HR via IP network, and the remote TVP-221H/TVP-224HR terminates the call. The destination of the call is the remote TVP-224HR/TVP-224HR.

8.4 Hunt Group

Instead of directly mapping a phone number to a destination, the ATPM first maps the phone number to a group of destinations known as a Hunt Group. A hunt group is a group of destinations that are equivalent. For example, the customer support group of a company might have 20 people who can handle support calls. Access to customer support is through a single phone number but the next available support person is actually connected upon each incoming call. These 20 phones would be configured as a hunt group. A hunt group consists of a phone number and a list of destinations (members of the group). When an incoming phone number matches the phone number of the hunt group, the TVP-224HR attempts to terminate the call at each of the destinations in the hunt group, one at a time until a call is successfully completed.

Every destination that can be reached by dialing a phone number is a member of at least one hunt group. When an address is presented to ATPM for lookup, the output is a hunt group ID number. As a second step, the hunt group ID is presented to ATPM to get the list of members. To effectively bypass the hunt group feature, simply assign a unique hunt group number to a single destination. In effect, the Hunt Group will just have this one member.

8.5 Dial Plan

The dial plan is a database inside the TVP-224HR that allows the ATPM to map telephone numbers dialed to IP addresses of remote VoIP Gateways. The dial plan consists of three tables; destination table, hunt group table and the address table. Users need to setup these tables in order for the TVP-224HR to process calls to remote VoIP Gateways.

Address Table

The address table maps a phone number to a hunt group. The table contains entries that specify the following information:

Telephone number
The hunt group the phone number maps to.
- The minimum number of digits to collect before the ATPM starts address lookup.
- The maximum number of digits the ATPM collects before it considers the dial string is complete.
Number of digits forwarded to the destination.

• Address table sample:

Address Entry	Hunt Grp_Id	Min. Digits	Max. Digits	Prefix strip	Prefix Address
201	3	3	3	3	None
301	4	3	3	3	None
8	1	3	3	0	None
0	1	1	1	0	None
20	11	5	5	2	None

Hunt Group Table

The hunt group table maps a hunt group to a list of destinations. Hunt group sample

Hunt Group ID	Hunt Type	# of Dest ID(s)	Dest. ID(s)
1	2	1	1
3	2	1	3
4	2	1	4
11	2	1	11

Destination Table

The destination table maps a destination to a telephony port or the IP address of a remote TVP-224HR.

Destination table sample

Dest ID	Mode	Destination
1	Local	Port = 0
3	Local	Port = 2
4	Local	Port = 3
11	H.323	Dest = 192.168.0.55/1720 TCP

8.6 DTMF Relay

Voice from PSTN is compressed by the TVP-224HR before it is sent across the IP network and then decompressed by the destination VoIP gateway. The voice codecs supported by the TVP-224HR are designed for ideally compressing and decompressing human voice. If the compression / decompression process is performed on DTMF tone which needs to be conveyed across IP network, distortion might be too significant to be cognizable on the receiving end. To overcome the shortcoming that the voice codecs may have encoding DTMF tone, the TVP-224HR encodes DTMF tone into special packets. The packets are then sent to the destination VoIP Gateway via a separate IP connection. The destination VoIP Gateway decodes the packets, generates the DTMF tone, and then sends the

tone to the PSTN. This method in which the TVP-224HR handles DTMF tone is so called DTMF relay.

The TVP-224HR handles DTMF relay per H.323 specifications. Certain third party VoIP devices may handle DTMF relay per IMTC standard. For the TVP-224HR to interoperate with those VoIP devices, users need to specify which remote VoIP devices use IMTC conforming DTMF relay technique. Refer to CLI command Error! Reference source not found. on Chapter 8 for detailed information on how to select DTMF relay mode.

8.7 Voice CODECs

Voice codecs supported by the TVP-224HR include G.711, G.723.1 5.3kbps, G.723.1 6.3kbps and G.729 AB. When setting up a call, two VoIP Gateways automatically negotiate with each other until an agreement on codec is determined.

TVP-224HR VoIP Gateway Router

Private-line automatic ringdown (PLAR) circuits have statically configured endpoints and do not require the user dialing to connect calls. The PLAR feature provides an easy method to create a switched Voice over IP (VoIP) call without digit dialing. PLAR connections are often referred to as a "batphone" or "hotline" type of application. This is when a phone goes off-hook

and a remote phone rings without digits being dialed. This is a useful tool for customer requirements such as:

• The provision of an Off-Premises eXtension (OPX) from a private branch exchange (PBX). Connection PLAR allows remote users on Foreign Exchange Station (FXS) ports to look to a central PBX like physical extensions.
• The provision of dial-tone from a remote PBX. Many customers want to offer toll-bypass VoIP services without having the routers provide dial-tone or change their existing dialplan. This allows stations at remote sites to look like they are physically connected stations to a PBX.

Dial in PLAR Considerations and Limitations

• Dial in PLAR is a switched VoIP call. The call is setup on an as-needed basis. With connection PLAR, no bandwidth is consumed while the phone is on hook. When a phone connected to a POTS dial peer is taken off-hook, the call is automatically connected and the remote phone begins to ring.
• Dial in PLAR can work between any type or combination of Foreign Exchange Office (FXO), and/or FXS) telephony port / device.
• Dial in PLAR does not collect digits from the connected Telephony device. Once a dial plan has been entered into the ATPM, PLAR can be enabled without need to alter the dial plan. Note: All other Dial plans set for this starting port will become ineffective.

9.5 Store Dial Plan

Store Dial Plan - will store the Dial Plan from DRAM / Working Memory to Flash / Non-Volatile Storage

Always be sure to Store, the Dial Plan from working memory / DRAM to Flash Memory / Non-Volatile Storage. Storing to Non-Volatile Storage ensures that you have saved the dial plan which can then be restored on request.

Note: The Dial Plan in the Non-Volatile Storage is not the working Dial Plan. If the Gateway is turned off for what ever reason, the Dial Plan from Non-Volatile Storage is copied into the Flash / Working memory and processes phone calls accordingly

9.6 Clear Dial Plan

Clear Dial Plan - Will clear the Dial Plan from DRAM / Working memory.

DRAM – Everytime you make an entry into the Address Table, Hunt Group Table or Destination ID table, you have to Click on Complete. This only saves the plan to the working memory / DRAM. If there was a power outage or the TVP-224HR was unplugged or a system crash for what ever reason, the Dial Plan in working memory / DRAM will be lost.

9.7 Restore Dial Plan

Restore Dial Plan - Will retrieve the Dial Plan from Flash Memory / Non-Volatile Storage but erase the dial plan currently in DRAM / Working memory.

Note: To ensure your new settings are actually accepted, please check the configuration page carefully after you submit the new settings. If the new settings are not present, it probably conflicts with the old settings. or there is not enough space to store your settings.

Making Calls with TVP-224HR

This chapters show how to make phone calls from telephony devices connected to the TVP-224HR directly through or indirectly.

10.1 Configuration Examples

Default Dial Plan

Before any configuration set up, your TVP-224HR should have the following basic default information.

Network

IP : 192.168.0.1

Mask: :255.255.255.0

Gateway :0.0.0.0

Dial Plan

No.	Hunt Group	Dest. ID	Dest.
201	1	1	0 (local port #1)
202	2	2	1 (local port #2)
203	3	3	2
204	4	4	3

1. If your TVP's two FXS ports are connected to two telephones, say port 2 and port 3 respectively, just pick up phone 203 and dial '204', phone 204 should ring.
2. 204 ⇒ TVP ⇒ local port #3 ⇒))))

You may also check the LED indicators on the TVP-224HR. When it rings, the related LED should flash. After you pick up the handset, it should remain on and off when the phone is on hook.

Now let's test your TVP-224HR that is equipped with 2 FXO interfaces. Assume you have one extension line with your PBX system, say, 201 as the extension number, we connect this line to the gateway's port 0 (FXO port), then connect a telephone phone set to port 3 (for example) of the gateway.

Pick up your extension handset, for example, 316 and dial '201'. After one ring, you should hear a dial tone. Now dial '203'. The telephone connected to the TVP's FXS port should ring.

If you do not hear the dial tone, please check the line impedance of your PBX. For a TVP-224HR with FXO port, please contact your PBX Supplier or System Integrator for further information

1. Now let's make a call to your PBX extension. Pick up the handset connected to the FXS port and dial '201', you should hear a dial tone (This means that TVP-224HR picks up the line connected to your PBX). Then dial '316', your extension handset should ring right away.

This guide only uses the default values. Once you are familiar with the dial plan set up, you may design your own dial plan.

10.2 Making a call with TVP-224HR FXS Port

TVP-224HR has two FXS ports. An FXS port can connect to an analogue phone directly, and a FXO port can connect to a PBX system or CO line.

Connection: Analogue telephone set connects to FXS port

Operation:

1. Pick up this analogue telephone set. You should be able to hear the dial tone provided by the TVP-224HR.
2. The corresponding green LED will light up when the telephone set is picked up. For Example: If the telephone set is connected to the second port of FXS. When you pick up the telephone set, the second green LED will light up.
3. We can dial the desired destination phone number at the telephone set. If the desired destination phone number is legal, the TVP-224HR will play two quick address ack tones, Du Du, to destination. If the desired destination phone number is illegal, the TVP-224HR will play three out of service tones, please check the dial plan and your desired destination phone number.

10.3 Making a call with TVP-224HR FXO Port

Connection: Analogue PBX connects to FXO port

Operation:

1. Pick up this analogue telephone set, you can hear the PBX dial tone provided by the PBX system. In some cases, you have to dial a specific number to get the connection between telephone set and PBX.

1. Dial the extension number for the gateway as provided by the PBX for the TVP-224HR FXO port.
2. When the TVP-224HR is connected, the corresponding green LED will be illuminated. For Example: If the telephone set is connected to the second FXO port, the second LED will be green.
3. We can dial the desired destination phone number on the telephone set. If the desired destination phone number is legal, the TVP-224HR will play two quick sounds, "Du Du", to destination. If the desired destination phone number is illegal, the TVP-224HR will play three out of service tones, please check the dial plan and your desired destination phone number.

10.4 Web Browser Sample Dial Plan

This section describes how to use a web browser to build a dial plan in the VoIP Gateway. We suggest the following:

Draw an application diagram to illustrate / clarify application including:

1. Local gateway: IP setup
2. Local gateway: local telephone number setup
3. Local gateway: remote gateway IP & remote telephone number setup

Note: The Diagram below of Gateway A & B could be any combination of either the TVP-224HR (connected to switch by WAN port) or the TVP-221H (Connected by LAN port). The switch that joins these two gateways serves the purpose of initial lab configuration. Under this configuration, both GW must be in the same IP segment. Once the dial plans have been entered and tested, the switch would be replaced by the public internet and the gateways would then have to be updated with the field application Internet Access Settings (eg. Public IP Address, Subnet Mask and Gateway IP Address). In addition, all remote destinations in the dial plan must be updated with the actual application / field IP Addresses.

This diagram serves the purpose of illustrating the possible analog phone / PBX / PSTN integration / applications of the Gateway.

However, disconnect cadence provided by your phone company for your PSTN line and disconnect cadence provided by your PBX may require additional matching with the gateway. This will require the assistance of your PBX supplier and/or Systems Integrator. Please also see User's Guide for additional information.

Scenario description: Two gateways connected by a switch.

There are two gateways connected by a switch. They are generically labeled "Gateway" but could be any combination of either the TVP-224HR (connected to switch by WAN port) or TVP-221H (Connected by LAN port). Theoretically, GW A is

Gateway A: Dial Plan Setup

FXS Ports to Analog Phones - Gateway A has two phones on the FXS ports.

Telephone number 203 on Port 2 and 204 on Port 3. These numbers are part of the default dial plan and do not have to be entered. We can skip the local Dial Plan setup including Telephone Address, hunt group and destination for phones 203 and 204.

How to Enter the Dial Plan

The Dial plan consists of three tables that include the Telephone Table, Hunt Group (eg. Customer Service may have multiple phones that the GW must search through for an open line), and Destination Table (Both Local and Remote). The dial plan has to be entered into all Gateways so that the local gateway knows how to process calls, sending them to its local ports or to remote gateways for further processing.

The following screen shots show an example for entering a dial plan for a single number. This example should give you the necessary insight as to how to enter the rest of the Dial Plan.

10.6 VoIP in a Dynamic IP environment

Internet Access

The previous section dealt with the TVP-222H in and its configuration in a static IP environment. The following section will address the issue of Dynamic IP and the TVP-224HR deployment in such an environment. This section we will show you how to connect two TVP-224HR in a dynamic IP address environment and configure PPPoE, DHCP, and DDNS clients.

10.7 PPPoE, DHCP, and DDNS clients:

In addition to fixed IP, the TVP-224HR can be configured to use PPPoE or DHCP clients. With PPPoE and DHCP, you will under most circumstances be assigned a Dynamic IP. In order for other people and devices to locate you, they will need to be pointed to your dynamic IP. Therefore, it is necessary that you register with a DDNS (Note: www.dyndns.org is currently the only service supported). Once you have registered an account, and have configured the DDNS client in the TVP-224HR, the TVP-224HR will automatically notify DynDNS of your changing IP Address. DynDNS will in turn, map your Dynamic IP to your registered Domain Name. See Chapter 6, DDNS section for more information.

The first time you connect to the TVP-224HR for configuration, you will need to connect to it under the same LAN segment to set the DHCP or PPPoE client. To configure the TVP-224HR, insert one end of an Ethernet cable into one of the 4 RJ45 LAN ports on the rear panel of the TVP-224HR and the other end directly to your PC Terminal. By default, the TVP-224HR's DHCP server is enabled. Make sure your computer is DHCP client enabled (See Chapter 4, PC Configuration). If you choose to assign a Fixed IP to your PC, make sure that you do not assign a IP that that is already allocated to the DHCP server for DHCP clients. The TVP-224HR supports auto MDIX so Cat 5 cable will be sufficient.

Case 4: Gateway Prefix-Simplified Gateway Phone to Gateway Phone

After these dial plans are added, users on Site A are able to dial “22 + extension number” to connect to users on site B for free VoIP telephony. Users on Site B are able to call phones on Site A for free VoIP telephony by dialing “11 + extension number”. (Note: There is a Max digit (5) limitation on the dial plan which allows the TVP-224HR to differentiate with potential PSTN numbers that may start with 11 or 22 but because they exceed 5 digits, they would be handled differently).

The benefits of this dial plan are:

1. Simplified setup
2. VoIP (Free calls to remote site extension)
3. Simplified dialing ensures easy, direct access to remote extensions.
4. Simplified dialing makes remote offices and branches feel like local extensions.

Two TVP-224HR Gateways (Both Gateways are set up with default settings)

1. TVP-224HR A, located site A
2. TVP-224HR B, located on site B.

Register DDNS name for both Dynamic IPs (See Chapter 6)

• tvp1.dyndns.org is applied for TVP-224HR on site A
• tsp2.dyndns.org is applied for TVP-224HR on site B

Clients used on this topology :

• TVP-224HR on site A has PPPoE, and DDNS clients enabled
• TVP-224HR on site B has DHCP, and DDNS clients enabled.

Once Internet Access is setup, you could choose to reboot the TVP-224HR, and then use a PC in the same segment and with a web browser, access theTVP-224HR:

If using the Router's DHCP Server, make sure the routers DHCP Server is on and that the configuring PC is DHCP Client enabled.

If you would like your PC to have a Fixed IP, Make sure that the IP does not conflict with the range of IP's allocated by the TVP-224HR's DHCP Server.

If you are trying to access the TVP-224HR from a PC in the same segment as the TVP-224HR (LAN), Open your browser and enter

1. Enter 192.168.0.1

If you would like to access the TVP-221H from the WAN side, from a remote PC with Internet Access:

Telephony Connections

This section discusses the special connection consideration for various environments and situations where you can use the VoIP Gateway.

11.1 Port Configuration

VoIP Gateway supports FXS and FXO ports.

FXS (Foreign Exchange Station)

FXS provides power and ringing signals to its interfacing equipment. It is not intended for connection to the Public Switched Telephone Network. It is a station loop start operation that provides a connection to:

1. A standard, single-line analog telephone system
2. The line circuit of a key telephone system
3. A loop start trunk circuit of a Private Branch Exchange (PBX) that normally connects to incoming Central Office circuits

FXO (Foreign Exchange Office)

FXO recognizes signals and draws current to indicate an active state. It is a trunk loop start operation that emulates a single-line telephone to:

1. Central Office lines
2. PBX station

There are three basic environments that the TVP-224HR can be applied to. They are described in the following sections.

Application 1: Special FXS Connections

The following diagram illustrates two different types of connections. The SITE A FXS Connection shows the normal connection between a gateway and telephone set (POTS) or FAX machine. The other type of FXS connection is shown on SITE B, on the right hand side. The Connection between the gateway and PBX has a special CO trunk interface card. The telephone sets connected to PBX can be either POTS or digital telephone depending upon the PBX capability.

Application 2: FXO Connections

Application 2 has three possible connections. One Site A, the FXS connection to analog devices is normal and is identical to connections mentioned in Application 1. On Site B, the connection between PSTN and PBX is also a normal connection. The last connection is between PBX and the gateway which uses the internal analogue lines of the PBX. In this case, the FXO port has to be used.

Note: If a digital PBX is used, an analog terminal adapter is needed to provide an analog interface to the FXO port. Please consult with your PBX supplier.

In this application, the caller on Site A, can make a call using a device connected to a FXS port on the Site A gateway. The call will be routed to the Site B Gateway, through a FXO port and passed on to the PBX system. The PBX system will then forward the call to the dedicated terminal / extension.

Troubleshooting Tips

This section provides solutions for problems you may possibly encounter while installing and connecting your VoIP Gateway.

Overview

This chapter covers some common problems that may be encountered while using the TVP-224HR and some possible solutions to them. If you follow the suggested steps and the TVP-224HR still does not function properly, contact your dealer for further advice.

General Problems

Problem 1: Can't connect to the TVP-224HR to configure it. Solution 1: Check the following:

1. The TVP-224HR is properly installed, LAN connections are OK, and it is powered ON.
2. Ensure that your PC and the TVP-224HR are on the same network segment.
3. If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it.
4. If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the TVP-224HR's default IP Address of 192.168.0.1. Also, the Network Mask should be set to 255.255.255.0 to match the TVP-224HR. In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol.

Internet Access

Problem 1: When I enter a URL or IP address I get a time out error.

Solution 1: A number of things could be causing this. Try the following troubleshooting steps.

1. Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address.
2. If the PCs are configured correctly, but still not working, check the TVP-224HR. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.)
3. If the TVP-224HR is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly.

Problem 2: Some applications do not run properly when using the TVP-224HR.

Solution 2: The TVP-224HR processes the data passing through it, so it is not transparent.

1. Use the Special Applications feature to allow the use of Internet applications which do not function correctly.
2. If this does solve the problem you can use the DMZ function. This should work with almost every application, but:
3. It is a security risk, since the firewall is disabled.

Note: Only one (1) PC can use this feature.

Other Problems

Power (PWR) LED is not illuminated

1. Check the power adapter connection.
2. If the power adapter or power cord is connected to the gateway, check that the cord is securely plugged into the power socket on the rear of the console.
3. Check that the other end of the power adapter or power cord is securely plugged into the power outlet.
4. If both ends of the power cord are properly connected and there is still no power, the gateway might have a faulty power outlet, power adapter or cord.
5. Change to another power outlet or obtain another power adapter or cord.

LNK LED is not illuminated

1. Check that the TVP-224HR was connected correctly:

a. Powered on
b. Correctly connected

1. Make sure connectors at both ends are securely seated.
2. Check the TVP-224HR IP setting is correct

Line port LED is not illuminated when I pick up the phone.

1. Check the RJ11 telephone line to make sure it is correctly connected to both telephone set and line port

There is no dial tone when I pick up the phone.

1. Check the Line port LED to make sure it is illuminated
2. Check the RJ11 telephone line to make sure it is connected correctly to both phone set and line port

There is an out-of-service tone when dialing the destination phone number.

1. Check the dial plan setting (address table, hunt group table and destination table) at the destination phone number

There is no connection tone when dialing the destination phone number

1. Check the IP network (Ethernet cable, Ethernet port and GW IP setting) is connected correctly
2. Check the destination TVP-224HR and phone is available

Final Steps

If the procedures in this section have not solved the problem, reset the gateway several times by turning the power on and off. If the problem still exists, contact customer support.

ATPM Destination Table

Local Destinations

Each telephony port of the TVP-224HR must be assigned a unique destination ID. Fill out the worksheet for local destinations by designating each port a unique destination ID, then use the CLI command atpm daddestid port port# for each entry in the worksheet to add it to the destination table. The dest_id in the command corresponds to the Destination ID in the worksheet, while the port# corresponds to the Port#. You may alternatively use the web browser to add local destinations to the destination table.

Port#	Mode	Destination ID
0	port
1	port
2	port
3	port

Remote Destinations

Each remote TVP-224HR to be reached must be assigned a unique destination ID. Obtain the IP addresses of the TVP-224HR at remote sites and fill out the worksheet for remote destinations by designating each

remote TVP-224HR a unique destination ID, then use the CLI command atpm dadd dest_id h323 ip_addr [ip_port] for each entry in the worksheet to add it to the destination table. The dest_id in the command corresponds to the Destination ID in the worksheet, the ip_addr corresponds to the Port#, the optional ip_port corresponds to the IP port. You may alternatively use the web browser to add remote destinations to the destination table.

ATPM Hunt Group Table

Several destinations may be grouped together to form a hunt group. When an incoming phone number matches the phone number of the hunt group, the TVP-224HR attempts to terminate the call at each of the destinations in the hunt group one at a time until a call is successfully completed. Plan how destinations are to be grouped and fill out the hunt table worksheet, then use the CLI command atpm hadd hunt_group_id hunt_type dest_id for each entry in the worksheet to add it to the hunt group table. The hunt_group_id in the command corresponds to the Hunt Group ID in the worksheet, the hunt_type corresponds to the Hunt Type (1 or 2), the dest_id corresponds to the List of Destination IDs. You may alternatively use the web browser to add hunt groups to the hunt group table.

Hunt Group ID	Hunt Type		List of Destination IDs
	1	2

ATPM Address Table

Each phone number to be recognized by the TVP-224HR must have its first digits match an entry in the address table. Fill out the address table worksheet and use the CLI command

atpm aadd tel# min_digits max_digits hunt_group_id prefixStrip_len [prefix#] to add each entry in the worksheet to the address table. The tel# in the command corresponds to the Digits to Match in the worksheet, the min_digits corresponds to the Min. # of Digits to Collect, the max_digits corresponds to Max. # of Digits to Collect, the hunt_group_id corresponds to the Hunt Group, the prefixStrip_len correspond to No. of Digits to Strip and the prefix# corresponds to the Prefix String. You may alternatively use the web browser to add telephone numbers to the address table.
