PASS The RLB test executed successfully. The test pattern was transmitted and
received successfully over the connection from the DS1 board to the
far-edge of the 120A CSU module/T1 sync splitter.

This test is destructive.
For documentation purposes, the term DS1 applies to the following:
DS1 Interface circuit packs
DS1 Interface media modules
UDS1 circuit packs.
The CPE Loopback Jack (CLJ-LB) test causes a loopback at the CPE loopback jack and tests
the building wiring connection between the DS1 board and the CPE loopback jack.
The test is highly destructive and can only be initiated by entering the command
test ds1-loop location cpe-loopback-jack-test-begin [number-of-bits
bit-pattern]. Enter a loopback activation code on the command line or use the default code
(0x47F).
Enter busyout board to busy out all trunks or ports on the DS1 Interface circuit pack before
running the CPE Loopback Jack test.
The CPE Loopback Jack test has the 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 framed 3-in-24 test pattern, begins counting bit
errors in the received test pattern, and returns a PASS result to indicate that the pattern was
successfully sent. If the loopback is not established within the 10 seconds, the test returns FAIL.
The status of the CPE Loopback Jack test appears in the error log as Error Type 3900. Several
distinct aux values give information on the status of the test.
