The Power "A" and/or "B" and VCC LEDs should be lit. TC8612 cards installed in the 1U rack chassis will not show the NOTE PWR A LED in the “On” lit state and will be Off. This is normal and the power to the card will be monitored by the VCC LED being “On”... -
Page 14: System Configuration
System Configuration The TC8612 has been pre-tested and switches have been set per factory specifications. The channels can be factory configured (in groups of four) for RS- 232, RS-422 and RS-485 interfaces at the time of ordering. -

Page 22: Local Loopback Test
1 & 2 of Port 1 will be looped back to pin 1 & 2 of Port 3. The loopback is formed inside the TC8612 after the input signal is converted to the TTL level. The purpose of this test is to verify the input and output wiring connections, signal input receiver and signal output driver. -
Page 23: Remote Loopback Test
Remote Loopback Test When you have completed the Local Loopback test for both units, proceed to the next step. Connect the local and remote TC8612 units as shown on the diagram below. Connect the T1/E1 connections as shown on the diagram below. Be sure to make the correct pin connections, refer to page 2-6 for pin assignments. -

The “LOS” LED should be off indicating that a valid T1/E1 signal is being received. If the “LOS” LED is flashing it means that the TC8612 is not receiving a valid T1/E1 or the T1/E1 cable is in question. -
Page 25: General
General Alarm conditions occur whenever a power or sync "fault" condition is detected by the TC8612. Under normal operation, PWR, Vcc, and SYNC LEDs should be lit. All LEDs are OFF If no LEDs are lit on the unit, check the DC power supply, connector plug, and/or the power source. -
