4.10. T1 Loopback Test
The T1 Loopback Test applies to boards having a T-1 front end. This test uses the front end set to local loopback on boards with a T-1 digital network interface to perform signaling and data loopback tests. It is a stand-alone test and does not require any other network interface boards or external loopback connector.
Parameters
| Number of Iterations |
Decimal number indicating the number of times the test will be executed. Default: 1
Valid Range: 1 to 32767 |
| Signaling Test |
The DSP generates signaling information and verifies that it receives the same signaling information. The signaling test is run four times, alternating the possible patterns for the A and B signaling bits (for example, AB = 00, 01, 10, 11). Default: run test on all time slots
Valid Range: 1 to 24 |
| Data Test |
Generates a data pattern in the DSP and then verifies that the DSP received the correct data. Default: run test on all time slots
Valid Range: 1 to 24 |
