Avaya 03-300430 User Manual

The DS1 circuit pack hardware applies a DC current while the test is running in order to detect 
any broken wires that may not be detected by the loop-back pattern.
When the test is complete, use release board to restore all trunks or ports on the TN767E 

DS1 Interface circuit pack to the in-service state.

Internal system error

1. Retry test ds1-loop location ds1/csu-loopback-tests at 

1-minute intervals up to 5 times.

CSU Equipment Loopback test cannot be executed in the current 
configuration. To run this test, the Near-End CSU Type field on the DS1 

circuit pack administration screen must be set to integrated and the Bit 
Rate field must be set to “1.544” (for 24-channel operation).

1. Use change ds1 location and set the Near-End CSU Type field 

on the DS1 circuit pack administration screen to integrated, and/or set 
the Bit Rate field to 1.544 if the board is to be used in a 24-channel 

configuration.

2. Retry test ds1-loop location ds1/csu-loopback-tests.

Ports on the DS1 Interface circuit pack have not been busied out to 
out-of-service.

1. Enter busyout board location to put all trunks or ports of the 

DS1 Interface circuit pack into the out-of-service state.

2. Retry the command.

The DS1 Interface circuit pack is providing timing for the system. Executing 

this test could cause major system disruption.
If the DS1 Interface circuit pack needs to be tested, set the synchronization 
reference to another DS1 Interface circuit pack or to the Tone-Clock circuit 
via the following command sequence: 

1. Enter disable synchronization-switch.
2. Enter enable synchronization-switch set 

synchronization location.

3. Enter enable synchronization-switch.
