CPE Loopback Jack Test (#1212)
This test is destructive.
The CPE Loopback Jack (CLJ-LB) Test causes a loopback at the CPE Loopback
Jack and tests the building wiring connection between the TN767E DS1 board
and the CPE Loopback Jack.

The CPE Loopback Jack Test has the TN767E DS1 Interface circuit pack transmit
a loopback activation code to the CPE Loopback Jack, waits up to 10 seconds
for return of the code to verify the loopback has been established, transmits a

The test could not relate the internal ID to the port (no board).
This could be due to incorrect translations, no board is inserted, an incorrect

command to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine if the board is hyperactive. If this is the case, the board is shut
