Page 4: Chapter 1 - Overview
Chapter 1 - Overview Description The Model TC1630R/S is a T1/E1 Fiber Optic Modem that converts analog T1 or E1 signals to digital fiber optic signal and vice versa. TC1630R is for 19" rackmount and TC1630S is for standalone unit. Both have the same functions and features, the only difference is power connectors. -

LEN0/LEN1/LEN2: These switches define the DSX-1 cross connect distance. There are 5 partitions to choose from. In a T1 application, this is the length of twisted pair cable connecting the TC1630R/S to the user's equipment, which may be a CSU or DSU. The cable lengths can be from 0 to 655 feet (see Figure Local LBT: This switch initiates the Local Loopback function. -

Page 9: Chapter 2 - Installation
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). -

2. Select the Line Length setting for T1: SW3, 4, 5 (see Figure 5). Slide the appropriate switches to the Down position. Depending on the distance between the TC1630R/S and the T1 cross connect, set the Line Length for the T1 transmit line driver according to the table below. When connecting to DSX-1 cross-connects for Line Lengths ranging from 0 to 655 feet, see DIP Switch Functions on page 6. -

If no LEDs are lit on the unit, check the DC power supply, terminal block connector plug, change to alternate power jack on the rear panel, fuses A and/or B indicated on page 17, and/or the power source. If the problem persists, contact the Technical Support Department at TC Communications, Inc. Alarm LED When an alarm condition is detected, the Alarm LED will flash. -
Page 13: Cable Connection Verification
1. Make sure all electrical signal connections match the pin assignments (I/O) for the device (check User's Manual if necessary). 2. Verify signal connections by checking the status LEDs on the front panel of the TC1630R/S. If the "LLOS" LED is flashing, a transmit signal is not being detected from the local device. If the "RLOS"... -

5. The "Vcc" LED should be illuminated. Please note: all other LEDs can be in a random state (flashing, solidly lit, or off) as only upon proper receipt and transmission of a signal will the TC1630R/S unit set its LEDs appropriately for normal operation. Proceed to the Local Loopback Test. -
