PRI test commands

See
test commands and a corresponding description of these commands. The
PRI test commands are in LD 60.
Table 12
PRI test commands in LD 60
Command Description
ATLP (0) 1
Automatic loop test enable (= 1) or disable (= 0) default.
1 = Loop test enable; this will cause far end to raise and clear remote alarm.
0 = Run the partial loop test; there is no interaction for the far-end loop
(default value).
SLFT L Invokes PRI self-test on loop L. The loop must be disabled because the test
disrupts call processing.
SLFT L CH Invokes partial PRI hardware self-test using channel CH of loop L.
RLBK L Closes the loop at the carrier interface point of the PRI so the far end can
perform an external loopback test. PRI loop L must be disabled because the
test disrupts call processing.
DLBK L Disables the remote loopback test per RLBK L. The loop remains disabled.
DLBK L CH Disables the remote loopback test per RLBK L CH. The channel remains
disabled.
RLBK L CH Per RLBK L, but performed on channel CH. This channel must be disabled
prior to issuing the request.
RMST L Performs self-test on loop L, providing the far end is in the remote loopback
mode.
RMST L CH Performs self-test on channel CH, providing the far end is in the remote
loopback mode.

PRI tests

PRI self-test
The self-test checks speech-path continuity, zero-code suppression, and
remote-alarm detection. This test is performed manually on a per-channel
or a per-frame basis.
The DCHI and PRI must be disabled before performing the self-test, or call
processing will be disrupted. To perform the self-test on a specific loop,
follow
