End Loopback/Span Test (#1216)
This test is destructive.
The End Loopback/Span Test will terminate an active loopback or span test on a
TN767E DS1 circuit pack. Bit error counting against the received test pattern
stream is terminated and sending of the framed 3-in-24 test pattern is halted. If
either the CPE Loopback Jack or the far-end CSU is looped, the appropriate
loopback deactivate code is sent. If the loopback could not be deactivated, then
the test will FAIL and a MINOR alarm will be noted in the alarm log until the
loopback is cleared.

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
