Page 4: Chapter 1 - Overview
Rev. 1.6 Description The Model TC1631R/S is a T1/E1 Fiber Optic Modem that converts analog T1 or E1 signals to digital fiber optic signal and vice versa. TC1631R is for 19" rackmount and TC1631S is for standalone unit. Both have the same functions and features, the only difference is power connectors. -

Slide the appropriate switches to the Right (On) position. Internal SW2-6, 7, 8 (see Figure 5). Depending on the copper distance between the TC1631R/S and the T1 cross connect, set the copper Line Length for the T1 transmit line driver according to the table below. When connecting to DSX-1 cross- connects for copper 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 16, 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 the signal connections by checking the status LEDs on the front panel of the TC1631R/S. If the "LOCRD" LED is "Flashing", a transmit signal is not being detected from the local device. If the "RMTRD"... -

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 TC1631R/S unit set its LEDs appropriately for normal operation. Proceed to the Local Loopback Test. -
