Procedure 38
Performing the Superloop Network card self-test
Step
To perform the self-test, follow the steps below:

.
DSBL: NOT RESPONDING = the loop is disabled and
the card is not responding (the card is missing, disabled
by the ENL/DIS switch, or faulty).
DSBL: RESPONDING = the loop is disabled and the card
is responding (the card is disabled with DISL command,
the Peripheral Signaling card is disabled, or an overload
condition exists).
Note: Overload conditions are indicated by OVDxxx
messages. Refer to Software Input Output Administration
(NN43001-611) () for the message description and indication
of the problem.
x BUSY, y DSBL = the loop is enabled with x channels
busy and y channels disabled.
CTYF L1 L2É = loop specified in STAT command cannot
receive speech from one or more loops or there is a
possible continuity test failure due to a faulty network
card such as the Superloop Network card.
Type ENLL sl and press the Enter key to enable the superloop,
where sl is the Superloop Network card superloop number. A
message indicating that the Superloop Network card is enabled
and working is displayed on the console. Also observe the red
LED on the Superloop Network card. If it turns off, the Superloop
Network card is functioning correctly. If the LED continues to
stay on, the Superloop Network card probably failed self-test and
a message should be displayed on the maintenance terminal to
that effect.
If the message indicates that the Superloop Network card is
faulty, replace the card.
If the Superloop Network card appears faulty, conduct
the self-test to verify that it is actually faulty before you
replace it. This test verifies the basic Superloop Network
card functions and outputs a fail or pass message after
the test is completed.
