1.9 PC & Network Security consideration

No system can be 100% protected against security threats. However, there are measures both manufacturers and users can do to help reduce the likelihood of a malicious attack resulting in either the loss of data or system takeover. We evaluate and improve our products continuously to protect against such attacks. This is only one safeguard used to reduce the likelihood of such an event. There are many more considerations needed to implement measures to strengthen your network security.

We strongly recommend the following considerations:

• Deploy Dispatch products and software on isolated networks that do not connect to other networks, when possible.
• Apply the latest Windows updates and install up-to-date IT security software.
• User rights should be properly administered using group policies to prevent unauthorized use of USB connected devices.
• If the Dispatch network must connect to other networks, install and properly maintain firewalls and intrusion detection systems.
• If Dispatch devices or computers use the Internet to connect, a VPN or tunnel connection should be utilized. Examples of such products are those made by DCB (Data Communications for Business), Cisco, and others.

Notice!

Bosch recommends utilizing the services of IT professionals knowledgeable about network design and security when designing, installing, and configuring dispatch networks and deploying PCs. By default, the Telex Dispatch products using the Windows operating system has Windows Update enabled along with Windows Defender (firewall and anti-virus). Disabling these features is not recommended unless it is part of an internal IT security program that uses customized security policies along with appropriate anti-virus and firewall software.

4 Communications System Design

Designing a system requires an understanding of the radio network and how the various radios and other communication equipment is connected.

Before you begin to design the system, create a road map of the radio, console, and any other communication equipment locations.

This road map must include the following:

– Multicast Addresses for each channel of TX (transmit) and RX (receive) communication.
- Port numbers for each channel of TX and RX communication.
- Base IP Addresses assigned to each console or radio on the network.
- The number of channels each radio may operate on.

4.1 Communications Control

Tone Remote Control

Telex Radio Dispatch sells a full line of tone control consoles and radio adaptors. This technology requires an analog connection between console and radio. Each console needing to control an individual radio is wired in parallel to allow multiple operator positions to monitor and control the same radio. For a large system with multiple console positions and multiple radio channels, an entire rack might be devoted to bridging audio to all interested parties. In addition, due to loading of multiple consoles on a particular circuit, additional bridging hardware might be required, increasing wiring and tuning of the system for acceptable performance. The Ethernet-based IP network solves many of these issues and provides for a number of other services not previously possible.

VoIP Radio Control

VoIP (Voice over Internet Protocol) is referred to generically throughout this document to mean RoIP (Radio over Internet Protocol). VoIP is a method of breaking analog audio up into packets to be transferred over a computer data network. Because Ethernet delivers information packets, audio is generally broken into 10-40ms chunks of audio, compressed, and placed on the Ethernet. The nodes of the network are then free to utilize or ignore any combination of packets. If a particular audio stream is of interest the stream of audio packets are captured, decompressed, converted back to analog, and played on available speakers. Given the popularity of the Ethernet-based networks, many companies and agencies already have an existing network or LAN (Local Area Network). Beyond that, a large number of companies exist to provide WAN (Wide Area Network) connections between sites with significant distances between them. The WAN connections can be used to connect offices across the street from one another, around the world, or anywhere in between. Possibly the best thing about these connections is they may already exist. In many cases, WAN links are less expensive than a comparable leased analog line and they can carry more conversations simultaneously.

The most compelling reason to consider basing the next radio control system upgrade on VoIP technology is the simplification in wiring requirements. Instead of needing to bring a pair or more of wires per channel to each console only a single connection to the Ethernet is required. Since Ethernet can easily handle dozens of simultaneous connections, it becomes the only pipeline required for all communications.

4.2 Network Security Considerations

No system can be 100% protected against security threats. However, there are measures both manufacturers and users can do to help reduce the likelihood of a malicious attack resulting in either the loss of data or system takeover. Our products and software continue to be

evaluated and improved to protect against such attacks. This is only one safeguard used to reduce the likelihood of such an event. There are many more considerations needed to implement measures to further strengthen your network security.

We strongly recommend the following considerations:

• Dispatch products and software be deployed on isolated networks that do not connect to other networks when possible.
• C-Soft be run on a dedicated PC with up-to-date IT security software installed.
• User rights should be properly administered using group policies to prevent unauthorized use of USB connected devices.
• If the Dispatch network must connect to other networks, proper firewalls and intrusion detection systems should be installed and regularly maintained.
• If Dispatch devices or computers must be connected through the Internet, a VPN or tunnel connection should be utilized. Examples of such products are those made by DCB (Data Communications for Business), Cisco, and others.

Notice!

Bosch recommends utilizing the services of IT professionals knowledgeable about network design and security when designing, installing, and configuring dispatch networks.

4.3 Network Requirements

IP Operation Overview

The network options today have converged on Ethernet. A local electronics store may sell many of the components for both a wired or wireless network solution. For more advanced network applications, an in-house or external network hardware resource may be required. These resources of information can also help with the design of the network, as well as, provide sources for advanced networking equipment such as routers and hubs from Cisco and other network vendors. This section is an overview of the protocols operating on top of the Ethernet network.

Ethernet as Physical Layer

Ethernet is a network and has a low-level method for transferring data from one location to another. Source and destinations are based on the MAC (Media Access Control) which is embedded in the Ethernet interface. The MAC Address is unique for all devices in the world and cannot be changed. The IEEE (Institute of Electrical and Electronics Engineers) controls the allocation of the MAC Addresses. The definition for Ethernet includes requirements for inter-operation at speeds of 10 and 100 Mbps. Higher speeds are available, but generally have not filtered down into end-user equipment.

Bandwidth

Each Telex 32K VoIP channel requires 50 kbits/sec of bandwidth while active. Full-duplex conversation requires 100 kbits/sec of bandwidth. Some radio systems transmit go-ahead beeps when it is clear to talk. In order for the console operator to hear the beeps, the system must support full-duplex communication. Full-duplex bandwidth may only be required for the first few seconds of a conversation due to the brief nature of the go-ahead beeps at the beginning of the transmission.

Multicast

In general, Telex Radio Dispatch systems require Multicast to function. The network must be able to create a static Multicast Address, that is accessible at all times.

Internet Group Management Protocol

IGMP can be used to control where Multicast is allowed to propagate. This should be limited to Subnets utilizing the C-Soft program as the dispatch console and only when used on an intermittent basis (when the C-Soft program is used for a period of time and then shut down). When a console on the Subnet is expected to be continually operational, Multicast must be active for the Subnet at all times.

Once an IGMP (Internet Group Management Protocol) join message is sent out, networks typically enable Multicast and then prune branches after a period of time. Due to intermittent usage patterns of 2-way radios, such a system can appear to work flawlessly for a period of time and then no longer work.

Notice!

When using Cisco technology, IP PIM dense mode is recommended. Sparse-dense-mode can also be implemented effectively. We recommend explicitly joining the Multicast group with an IP IGMP static-join X.X.X.X command. For more information on Cisco and IGMP, visit www.cisco.com.

Network Performance

Networks should perform well under any loading conditions. The default audio delay is 200ms, plus any delay added by the network. While delay alone does not cause issues, variable delay (also known as jitter) does. Jitter in a network cannot exceed the maximum packet buffer of any individual product buffer. Refer to the individual product manuals for these specifications. For example, the IP-224 can handle a maximum of 600ms of network jitter.

Notice!

Losing more than 5 percent of the total packets transmitted compromises audio quality and system performance. Optimal packet loss should be less than 1 percent.

TCP/IP and UDP/IP

TCP/IP (Transmission Control Protocol/Internet Protocol) is the best-known protocol for use in computer communications. It is the basis for communications on the Internet and World Wide Web. It is a guaranteed method of transferring data between two computers. Being guaranteed means for every packet of information transferred from one computer to another, an acknowledgement packet is returned. Additional handshaking is utilized from the outset of the data communications to ensure both ends of the connection. Because of this guaranteed communications and its implementation utilizing handshaking (no other method is available), TCP/IP adds a great deal of overhead to data communications that is not desirable for audio traffic over a network. This is where UDP/IP finds its acceptance.

UDP/IP (Universal Datagram Protocol/Internet Protocol) has existed as long as TCP/IP as an unreliable method of data communications. The term unreliable should not be thought of as a problem for audio communications over a network connection. UDP allows a computer to send a packet of data to another computer without the handshaking sequence required within

TCP/IP. Because of this, the computer sending the packet has no confirmation the packet arrived at its destination. While the loss of packets can be a problem, it generally is accounted for when the UDP application is developed. In the case of VoIP, the loss of a packet, which only contains 10-40ms of audio, is not a problem, as the human ear generally ignores the small chunk of lost audio. The largest single factor in the loss of UDP/IP packets is network design and loading. As long as a network is well designed with capacity for all of its chartered requirements, packet loss can be a non-issue. Because of its lower overhead and its ability to Multicast, UDP/IP is the protocol of choice for VoIP development.

Multicast UDP/IP

Multicast is an extension to UDP/IP. It enables one computer to broadcast data packets to multiple recipients. This is an ideal model for radio communications when multiple people need to monitor the audio. A single VoIP connected radio is setup to broadcast Multicast VoIP packets when receiving audio. Since the Multicast packets can be received by any interested party, all consoles monitoring the audio can receive and decode the packets for playback. In addition to simplifying monitoring of audio traffic by multiple listeners, Multicast also greatly reduces the bandwidth requirement on the network. Instead of having to regenerate the received audio into a UDP/IP data stream to each individual monitoring console, which uses the bandwidth times the number of monitoring consoles; a single data stream is generated and monitored by all.

Implementation of a Multicast protocol requires a few things for seamless use on a network. First, clients must all support the protocol. This is accepted as given since all Telex Radio Dispatch products utilize Multicast for audio communications. Second, consider if the network infrastructure supports Multicast. Multicast packets are defined to be all packets with a destination address of between 224.0.0.0 and 239.255.255.255. Some of these addresses are commonly used for broadcast audio and are not necessarily available. When a computer opens a UDP/IP port within this address range, it also joins the group. By joining the group, a packet is sent out to all addresses saying it is interested in seeing the traffic on this Multicast Address. Routers that receive this broadcast message to join a particular Multicast Address then pass packets through because the router is now aware a listener is interested in this traffic. The routers utilized in the network must support this. The protocol used to alert routers to parties who are interested in certain Multicast Address traffic is IGMP. Telex Radio Dispatch products support IGMPv1and v2, as defined in RFC 1112.

In addition to the joining of Multicast broadcast groups, clients on the network can also specify a packet TTL (Time-To-Live). The TTL is the number of routers the packet goes through before being stopped. As an example, the TTL for a particular broadcasting node on the network is set to three. This means when a packet is transmitted, it arrives at the first router in the network. This router examines the TTL value in the packet and determines if it should pass it through since it is not zero. When it passes the packet, the router decrements the TTL value by one to a value of two. The next router encountered by packets does the same, reducing the value of TTL to one. The next router does the same and the TTL is reduced to zero. The next router the packet reaches examines the TTL value, sees it is zero, and the packet is not to be retransmitted. Setting a large TTL value may allow for packets to get from one host to another on a large network, but also adds additional bandwidth requirements due to the larger number of packets being transferred.

Telex Port-Centric Method

As mentioned earlier, Telex utilizes Multicast for all audio communications. Typically, only one Multicast is used for all traffic. In addition to a valid Multicast Address, a port number is required. The port is an additional two bytes of information ranging between 1054 and 65535 that further specifies how the data traffic should be handled. For example, assume the base Multicast Address chosen is 225.8.11.81. Port 1054 is used to distinguish channel 1's RX traffic. Port 1072 is used to specify channel 1's TX traffic. Channel 2 might use 1055 for RX and 1073 for TX traffic. By making each channel's TX and RX ports unique, full-duplex1audio can be supported and many channels of traffic can be supported using only one Multicast Address. It is through this method a single console can select the particular radio resources available on the network without concern for what the console right next to it is utilizing.

Figure 7.2: Ethernet Setup Window (2 of 2)

7.2.1 Ethernet Port Setup

Auto Failover Enabled Check Box

The Auto Failover Enabled check box, if selected, enables the IP-224 to ping a network IP Address with the Primary or Secondary Ethernet port. When the IP-224 boots, it sets the Primary Ethernet port as active. If the Auto Failover is enabled, the IP-224 pings the Primary Ethernet port's Ping IP Address. If the ping fails with the Primary Ethernet port, the IP-224 switches to the Secondary Ethernet port. The IP-224 continues using the secondary Ethernet port until the ping fails on the secondary network, the port selection is changed via the web page/display, or the IP-224 is rebooted.

The Auto Failover can also be changed via the front panel of the IP-224. This is the ping command with the fields described in the sections below:

Ping-c -W

Notice!

Validate the Primary Port and Secondary Port Ping IP Addresses when enabling Auto Failover. If neither the Primary nor the Secondary Ping IP Address can be pinged successfully, the Active Port will continuously switch between the Primary and Secondary Ethernet ports. This will lead to an unreliable network connection to the IP-224.

Current Active Port Field

The Current Active Port field is used to view the IP-224's current active Ethernet port. This field is automatically populated and cannot be modified.

Notice!

The Current Active Port can also be seen on the System Status web page or via the front panel display line selection icon where an asterisk (*) indicates the Primary Ethernet port is active and a pound sign (#) indicates the Secondary Ethernet port is active.

Set Active Port Radio Button

The Set Active Port radio button is used to manually select the active Ethernet port on the IP-224. The active port can be changed regardless of the Auto Failover Enabled setting (for debug/setup purposes).

Available selections are:

Primary — Select Primary to set the PRIM Ethernet port on the IP-224 as the active port (Default).

Secondary — Select Secondary to set the SECOND Ethernet port on the IP-224 as the active port.

Primary Port Column

The Primary Port column is used to enable DHCP, set the unit's IP Address, Subnet Mask, Gateway, Ping IP Address, Ping Count, Ping Timeout, and Time Between Pings for the PRIM Ethernet port on the IP-224.

Secondary Port Column

The Secondary Port column is used to enable DHCP, set the unit's IP Address, Subnet Mask, Gateway, Ping IP Address, Ping Count, Ping Timeout, and Time Between Pings for the SECOND Ethernet port on the IP-224.

DHCP Enabled Check Box

The DHCP Enabled check box, if selected, allows the IP-224 to acquire IP Addresses and other network configuration settings automatically when connected to a network.

Notice!

The network must allow DHCP service before the IP-224 can get the network parameters. Radio Dispatch does not recommend operating with DHCP enabled. Operating with DHCP enabled may cause the base IP Address to change unexpectedly, making changes to the software setup more difficult.

Unit IP Address Field

The Unit IP Address field is used to display or set the unit's IP Address. The web browser configuration uses the IP Address to identify the IP-224 for such operations as set up, software upgrades, and communication on the network.

Subnet Mask Field

The Subnet Mask field is used to display or set the unit's Subnet Mask Address. The Subnet Mask is used to distinguish local addresses from addresses requiring the use of a gateway to reach other networks. Contact your Network Administrator to obtain the proper value for this field.

Default Gateway Field

The Default Gateway field is used to display or set the unit's gateway address. The gateway address is used to connect to another network.

Ping IP Address Field

The Ping IP Address field is used, when Auto Failover is enabled, to set the network IP Address used in the ping command to determine if the IP-224 needs to switch Ethernet ports. If the network IP Address is unreachable, the ping command fails, and the IP-224 switches Ethernet ports.

The Ping IP Address can be changed via the front panel of the IP-224.

Ping Count

The Ping Count field is used, when Auto Failover is enabled, to set the number of ping attempts used in the ping command to determine if the IP-224 needs to switch Ethernet ports.

The IP-224 attempts to ping the network IP Address the number of times configured in the Ping Count field. If the Ping IP Address is unreachable for ALL ping attempts, the ping command fails, and the IP-224 will switch Ethernet ports.

The range for this field is 1 to 10.

The Ping Count can also be changed via the front panel of the IP-224.

Notice!

The ping command inserts a 1 second delay between each ping attempt when the Ping IP Address is unreachable. For example, if the Ping Count is set to 5, the ping command requires a minimum of 4 seconds to complete for an unreachable Ping IP Address.

Ping Timeout

The Ping Timeout field is used, when Auto Failover is enabled, to set the timeout in seconds that is used to cancel the ping command. The timeout is started after all the Ping Count attempts have been sent. If the timer expires and the ping command is still active, it cancels the ping command. If ALL ping attempts failed before the ping command was cancelled, then the IP-224 switches Ethernet ports.

The range for this field is 1 to 20 seconds.

The Ping Timeout can also be changed via the front panel of the IP-224.

Notice!

There is a 1 second delay between each ping attempt. The ping command is cancelled in (Ping Count - 1) seconds plus Ping Timeout seconds when the Ping IP Address is unreachable. For example, the Ping Count is set to 5 and the Ping Timeout is set to 10, the ping command is cancelled in 14 seconds for an unreachable Ping IP Address.

Time Between Pings

The Time Between Pings field is used, when Auto Failover is enabled, to set the amount of time in seconds between ping commands. When a ping command completes, either successfully or unsuccessfully, this is the amount of time before the next ping command is executed.

The range for this field is 5 to 60 seconds.

The Time Between Pings can also be changed via the front panel of the IP-224. For more information, see Network Settings, page 94.

Auto Failover Web Page Setup

To configure the IP-224, do the following:

1. Open the IP-224 web application.

2. From the left navigation, select Ethernet Setup.

The Ethernet Setup window appears.

1. Select the Auto Failover Enabled checkbox.

Notice!

The IP-224 always selects the Primary Port at power up.

1. In the Primary Port and Secondary Port fields, enter the Ping IP Address.

Notice!

Verify the network IP Addresses are reachable on the corresponding Primary and Secondary network.

1. In the Primary Port and Secondary Port fields, enter the Ping Count.

2. In the Primary Port and Secondary Port fields, enter the Ping Timeout.

3. In the Primary Port and Secondary Port fields, enter the Time Between Pings.

7.2.2 IPv6 Setup

IPv6 Enable Check Box

The IPv6 Enable check box, if selected allows the IP-224 to be addressed and configured using IPv6.

Link Local Address Field

The Link Local Address field is a 128-bit address field. It is not editable. It is an auto-configured address field and starts with FE in hexadecimal. The link local address is used to route the local network device only and cannot be routed to public networks. The link local address is generated from a local device MAC address.

Notice!

The Link Local Address text next to the field is a direct link. Click the text to go directly to the web page configuration of the device.

Unit IP Address Field

The Unit IP Address field is used to display or set the unit's IPv6 Address. The web browser configuration uses the IPv6 Address to identify the IP-224 for such operations as setup and communication on the network. The IPv6 address size is 128 bits and is represented in hexadecimal format. The 128-bit address is divided into eight 16-bit blocks. Each 16-bit block is converted to a 4-digit hexadecimal number and is separated by colons.

Notice!

The Unit IP Address text next to the field is a direct link. Click the text to go directly to the web page configuration of the device.

Subnet Prefix Length Field

The Subnet Prefix Length field is used to identify how many bits of the global IPv6 address are used for the network portion. The prefix length in IPv6 corresponds to the subnet mask field used in IPv4. However, rather than being express in four octets like in IPv4, it is expressed as an integer between 1 through 128.

The default for this field is 64.

Gateway Field

The Gateway field is used to configure the unit's gateway IPv6 Address similar to IPv4 setting. It is used to connect the device to another network.

7.2.3 Packet Setup

Packet Delay Before Playback Field

The Packet Delay before Playback field is used to enter a delay period for the audio packets before they are played. The IP-224 uses a 20ms UDP/IP packet to encode audio. Some buffering of these packets must occur before playback to help absorb network delays, jitter, and lost packets.

The range for this field is 4 to 29.

The typical entry for this field is 10, which translates to a delay of 200ms before playback (each packet is 20ms of audio). Larger values may be required for complicated networks, and smaller values for less complicated networks.

QOS Precedence Bits Field

The QOS (Quality of Services) Precedence Bits field is used to set the priority level of network traffic.

The range for this field is 0 to 7.

Typically, this value is set to 0 for normal voice traffic.

QOS D, T, and R Bits Field

The QOS: D, T, and R Bits field is used for advanced programming purposed. Contact your Network Administrator to obtain the appropriate value for this field.

- Delay (D) - An active delay bit directs the router to choose a high speed to minimize delay.

- Throughput (T) - An active throughput bit specifies that high capacity lines should be used.

- Routing (R) - An active routing bit directs routing protocols and network management applications to select fault tolerant paths.

The range for this field is 0 to 7. Typically, this value is set to 0.

Auto Failover Check Box

The Auto Failover Enabled check box, if selected, enables the IP-224 to ping a network IP Address with the Primary or Secondary Ethernet port. When the IP-224 boots, it sets the Primary Ethernet port as active. If the Auto Failover is enabled, the IP-224 pings the Primary Ethernet port's Ping IP Address. If the ping fails with the Primary Ethernet port, the IP-224 switches to the Secondary Ethernet port. The IP-224 continues using the Secondary Ethernet port until the ping fails on the secondary network, the port selection is changed via the web page/display, or the IP-224 is rebooted.

The Auto Failover can also be changed via the IP-224 web page configuration. This is the ping command with the fields described in the following sections:

ping -c -W

Notice!

Validate the Primary Port and Secondary Port Ping IP Addresses when enabling Auto Failover. If neither the Primary nor the Secondary Ping IP Address can be pinged successfully, the Active Port continuously switches between the Primary and Secondary Ethernet ports. This leads to an unreliable network connection to the IP-224.

Notice!

The current active port can be seen on the Ethernet Setup web page, System Status web page, or via the front panel display line selection icon where an asterisk (*) indicates the Primary Ethernet port is active and a pound sign (#) indicates the Secondary Ethernet port is active.

8.4 Console Mode

Console Mode allows an analog tone console to be configured as a networked IP console resource. The IP-224 implements console mode to encode/decode industry standard tones allowing an analog tone console to control and monitor radio traffic via an IP network.

Features

• 2/4 Wire Tone Operations
• 6-Wire E&M Audio and Logic Operation
• RX and TX Audio, Simplex or Full-Duplex
• PTT and Monitor Decode
• Up to 16 Channel Changes
• Parallel Console Cross-Muting and Supervisor Function
• Parallel Console Updating from Remote Console Changes

IP-224 in Console mode
IP-224 in Tone mode

Console PTT

PTT tones and microphone audio generated by the analog console are decoded by the attached IP-224 operating in Console Mode, and CTX Fx (x = Frequency) will be shown on the unit's display. In addition to 2/4 wire tone operation, the IP-224 can support 6-wire E/M (Local) analog console input, controlling a single frequency.

The PTT tones are notched (removed) and the microphone audio is sampled and VOCODED for IP transport. TX packets are created with the decoded frequency tone in the packet header, and the voice payloads are transmitted to the network for transport to the radio end IP-224 in Local or Tone Modes.

The radio end IP-224 will receive and decode the network packets, regenerate the PTT tones, and insert the audio created at the analog console end IP-224 to the connected tone remote or radio.

Radio Receive

The radio end IP-224 receives RX audio from the attached radio. RX Fx (x = Frequency) will be shown on unit display and RX packets are generated to the network.

The analog console end IP-224 will receive and decode network packets. CRX Fx (x = Frequency) will be shown on unit display and RX audio is regenerated to the attached analog console.
