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 TC1630R/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
The TC1630S is powered by an external DC power adapter rated 12VDC @250mA. There are two power
jacks at the rear panel for power redundancy. TC1630R is the rackmount version of the TC1630S. It can
be inserted into the card slot when power is on (hot swapable).
T1/E1 Connection
Two pairs of terminal block connectors and/or an RJ-45F connector 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 TC1630R/S (receive), while the right pair of terminal block connectors are for the transmit
signal coming out of the unit. Note: The T1/E1 signal can be connected to either the terminal block connectors
or the RJ-45F connector, but not on both at the same time, refer to page 7.
Dry Contact Alarm Switch
A terminal block connector at the rear panel provides for the Dry Contact Relay Alarm. Normally in the
CLOSED position, any alarm condition will force the switch to the OPEN position. This relay can be
configured by the user if necessary (see Chapter 3 - Troubleshooting).
Installation Procedure
The TC1630R/S is designed for quick and easy installation. First, configure the modem for your specific
application by setting the Line Code and Line Length DIP switches. Once configured, you can connect the
optical, T1/E1 signal source and power.
Installation Procedure:
1. Select the Line Code (SW6, 7, 8).
2. For T1, select the Line Length (SW3, 4, 5).
3. Connect the T1/E1 signal source, either terminal blocks or RJ-48C connector.
4. Connect the optic cables. Verify single mode or multimode optic cable according to your TC1630
ordered. Using incorrect optic cables will result in a malfunction. Verify optic connections.
5. Connect the power. All the LEDs should flash for approximately three seconds.
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.
