Unpacking the Unit

Before unpacking any equipment, inspect all shipping containers for evidence of external damage caused

during transportation. The equipment should also be inspected for damage after it is removed from the

container(s). Claims concerning shipping damage should be made directly to the pertinent shipping agencies.

Any discrepancies should be reported immediately to the Customer Service Department at TC Communi-

cations, Inc.

Equipment Location

The TC1631R/S should be located in an area that provides adequate light, work space, and ventilation. Avoid

locating it next to any equipment that may produce electrical interference or strong magnetic fields, such as

elevator shafts or heavy duty power supplies. As with any electronic equipment, keep the unit from excessive

moisture, heat, vibration, and freezing temperatures.

Power Supply

Standard input power to the TC1631S is 12VDC @350mA. There are two power jacks at the rear panel for

power redundancy. TC1631R is the rackmount version of the TC1631S. It can be inserted into the card slot

when power is on (hot swapable).

T1/E1 Connection

Two pairs of terminal block connectors are provide for the connection of the T1/E1 wire pairs. When viewing

the rear panel, the left pair of terminal block connectors are for T1/E1 signal going into the TC1631R/S

(receive), while the right pair of terminal block connectors are for the transmit signal coming out of the unit,

refer to page 7.

Dry Contact Alarm Relay

A terminal block connector at the rear panel provides for the Dry Contact Alarm Relay. Normally in the

OPEN position, any alarm condition will force the switch to the CLOSED position. This relay can be

configured by the user if necessary (see Chapter 3 - Troubleshooting).

Installation Procedure

The TC1631R/S is designed for quick and easy installation. First, configure the modem for your specific

application by setting the Line Code DIP switch. Once configured, you can connect the optical, T1/E1 signal

source and power.

Installation Procedure:

1. Select the Line Code (SW1-3).

2. For T1, the Line Length has been factory set to "0-133 feet."

3. Connect the T1/E1 signal source to the terminal block connectors on the rear panel.

4. Connect the optic cables. Verify single mode or multimode optic cable according to your TC1631

ordered. Using incorrect optic cables will result in a malfunction. Verify optic connections.

5. Connect the power. All the LEDs (except for PWRA and/or PWR B and Vcc) should flash for

approximately one second.

After installation is completed, it is an excellent idea to verify the optical cable loss. This reading will both

verify the integrity of the circuit and provide a benchmark for future troubleshooting efforts.
