Frequently Asked Questions - MT195A-T1 Black Box

What is the data rate of the Black Box MT195A-T1?

The MT195A-T1 operates at 1.544 Mbps (T1 rate).

How do I connect power to the MT195A-T1?

Connect the AC power cord to the external adapter, then connect the adapter's barrel plug to the Power connector on the unit. Plug into a 100–240 VAC outlet. The Power LED should light up.

What type of cable is used for the line port?

Use a single twisted-pair cable with RJ-45 connectors at both ends. Connect one end to the Line port (RJ-45).

How do I connect the MT195A-T1 to a T1 circuit?

Attach a twisted-pair cable with an RJ-48C connector to the T1/E1 port on the unit. Connect the other end to the T1 circuit or device. Use a straight-through cable for direct circuit connection, or the included crossover cable when connecting to a device.

What do the front-panel LEDs indicate?

The Power LED indicates the unit is on. Link LED: solid when link is connected, off when no signal, flashing during data transmission. Frame LED: solid when T1 frame is connected, off when no signal, flashing on error.

Do I need to configure DIP switches?

No, the MT195A-T1 is Plug 'n' Play and requires no configuration. The only exception is switch S1-7 for Line Build Out adjustment (default ON for 0.0dB). Do not change other switches unless instructed by Black Box support.

What is the line coding used?

The MT195A-T1 uses TC-PAM (Trellis Coded Pulse Amplitude Modulation) on the line interface.

Can the MT195A-T1 be used in residential environments?

No, it is a Class A device intended for light industrial or commercial use. It is not approved for residential or heavy industrial environments due to potential radio interference.

How do I troubleshoot if the Link LED does not light?

Check that both the local and remote extenders are powered on and connected properly. Verify the twisted-pair cable is correctly wired and not damaged. Ensure the Line ports are connected and that the remote unit is synchronized. If the issue persists, contact Black Box tech support.

What are the environmental specifications?

Operating temperature: 32–122°F (0–50°C), humidity: 5–95% non-condensing, altitude: 0–15,000 ft (0–4,572 m).

1.2 Description

The Black Box T1/E1 Extenders provide high speed 2-wire T1/E1 extension connectivity to ISPs, PTTs, and enterprise environments using binder group friendly TC-PAM modulation.

Line connection is made with an RJ-45 jack. Models MT196A-E1 and MT195A-T1 are powered by an 100/230 VAC (Universal) supply. The NTU features externally-accessible DIP switches, loopback diagnostics, and Plug 'n' Play.

2. Installation

Because the T1/E1 Extenders require no configuration, they can be installed quickly. Installation consists of the following:

• Connect the power plug (refer to section 2.1, “Connecting Power” on page 10).
• Connect the line port (refer to section 2.3, “Connecting the Line Port” on page 11)

Note See Figure 1 and Figure 2 for the rear-panel connectors locations.

- Connect the T1/E1 port (refer to section 2.4, “Connecting the Circuit Interface” on page 11).

Figure 2. Model MT195A-T1 rear panel

2.1 Connecting Power

The external AC adaptor shall be a listed limited power source that incorporates a disconnect device and shall be positioned within easy reach of the operator. Ensure that the AC power cable meets all applicable standards for the country in which it is to be installed, and that it is connected to a wall outlet which has earth ground.

Your T1/E1 Extender comes with an external AC adaptor with a detachable power cord.

To connect power to the T1/E1 Extender:

1. Connect the female plug of the AC power cord to the AC adaptor provided.
2. Connect the barrel-type connector of the AC adaptor to the Power connector on the T1/E1 Extender.
3. Insert the male plug of the AC power cord into the AC power outlet (100-240 VAC).
4. Verify that the Power LED on the front panel illuminates and remains lit.

2.2 Power Input Connector

The T1/E1 Extender comes with an AC power supply.

- The supplies connection to the T1/E1 Extender is a 2.5 mm barrel receptacle with the center conductor positive (see Figure 3).

Figure 3. Power connection barrel receptacle diagram

• T1/E1 Extender's rated voltage: 5.0 VDC
• T1/E1 Extender's rated current: 1 A DC

2.2.1 EXTERNAL AC UNIVERSAL POWER SUPPLY

• Output from power supply: 5 VDC, 2A
- Input to power supply: universal input 100–240 VAC 50/60 Hz 0.3A

2.3 Connecting the Line Port

CAUTION

The interconnecting cables shall be acceptable for external use and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and mechanical serviceability.

Follow the steps below to connect the line port:

1. Obtain a single-twisted pair cable with an RJ-45 plug connector at each end.
2. Plug one end of the cable into the RJ-45 socket (labeled Line) on the T1/E1 Extender.
3. When the remote and local extender units synchronize, the front-panel Link LED will turn on.

2.4 Connecting the Circuit Interface

Your T1/E1 Extender comes with either an RJ-48C or an RJ-48C and dual BNC for connection to a T1 or E1:

• Model MT196A-E1 - E1: 120-Ohm RJ-48C and dual 75-Ohm BNC connectors
  • Model MT195A-T1 - T1: RJ-48C

To connect the twisted pair cable to the T1/E1 port:

1. Attach the male connector of the twisted pair cable to the female RJ-48 connector on the T1/E1 Extender.
2. Attach the other end of the cable to the RJ-48 connector on the local T1 or E1.

Note When attaching the T1/E1 Extender directly to a T1/E1 circuit, a straight through twisted pair cable can be used. When attaching the MT196A-E1/R or MT195A-T1/R to a device, please use the enclosed T1/E1 cross over cable for proper operation.

Note The unit marked as MT196A-E1/L or MT195A-T1/L is configured by default to accept timing from the T1/E1 circuit. The MT196A-E1/R or MT195A-T1/R unit then recovers this timing from the line in order to ensure synchronization of the T1/E1 circuit over the extenders.

3. Operation

Once the T1/E1 Extenders are properly installed, they should operate transparently. No user settings required. This section describes reading the LED status monitors.

3.1 Front Panel LED Status Monitors

Models MT196A-E1 and MT195A-T1 feature three front-panel LEDs that monitor power, Ethernet signals, and the CopperLink connection. Figure 4 shows the front panel location of each LED. Table 1 describes the LED functions.

Link On solid—link is connectedOff—No signal detectedFlashing — Data is being transmitted/received

Frame On solid—T1/E1 frame is connectedOff — No signal detectedFlashing — Error detected

3.2 Configuration and Dip Switches

The T1/E1 Extenders are Plug ‘n’ Play enabled and do not require any configuration by the user.

Note The user should NOT change any of the dip switches except for S1-7 (if necessary). If the user changes the position of any of the dip switches (except for S1-7), it will affect the operation of the unit. Refer to Appendix B. on page 16 for the factory default dip switch configuration.

3.2.1 SWITCH S1-7: LINE BUILD OUT

Switch S1-7 defines the shape of the waveform on the T1 or E1 line.
