Line Loopback Test

The Line Loopback Test is used for both the 100R INA and for the 100 DCD modules. This test
loops the T1 interface back towards the network on the network side of the framer. To perform this
test, you must first busy-out the module. From your system programming console, use the
following sequence to access the Line loopback test.
When this test is activated, the far end generates the test pattern using the built-in BERT
Tests or other data-generating equipment.
Procedure
Appropriate Modules This test can be run on the 100R INA and 100 DCD modules only.

Payload Loopback test

The Payload Loopback Test is used for both the 100R INA and for the 100 DCD modules. This test
loops the T1 interface back towards the network on the communications system side of the framer.
To perform this test, you must first busy-out the board. From your system programming console,
use the following sequence to access the Payload loopback test.
When this test is activated, the far end generates the test pattern using the built-in BERT
Tests or other data-generating equipment.

Bit Error Rate Test (BERT)

The Bit Error Rate Test is used for both the 100R INA and for the 100 DCD modules. This test
allows you to generate several test patterns and monitor the progress of the test to see if the
pattern being generated is being received back. The error count and state of the test represents a
real-time snapshot of the information available in dual-port RAM (DPRAM).
