Demand Tests

The INA module board incorporates three new demand tests:

•Line loopback

•Payload loopback

•Bit error rate test (BERT)

Line Loopback Test

The line loopback test loops the T1 signal back towards the network without regenerating framing and without recalculating a cyclic redundancy test (CRC) checksum. To perform this test, you must first busy out the INA module. From your system programming console, use the following sequence to start the line loopback test:

Menu: Maintenance→ Slot→ Slot#→ Enter→ Demand test→ LineLpbk

After the line loopback test has been started, selecting → Back terminates the test.

Note – During the line loopback test, the INA module transmit clocking is derived from the signal received by the INA module. The remote end of the T1 connection must be
