128 Remote IPE maintenance
Superloop Network card fault isolation and correction
The Superloop Network card provides a communication interface between
the CPU in the local system and the Peripheral Controller card in the
Remote IPE.
The Superloop Network card processes signaling information and data
received from the Peripheral Controller card over the fiber-optic link.
Problems with the Superloop Network card may be caused by hardware
faults, incorrect configuration, a disabled Superloop Network card, or
continuity problems between the card and other network cards connected
to the network bus. To isolate and correct problems with the Superloop
Network card, follow the procedures below.

problems" (page 126)
Network card may be faulty or disabled. The first step
in identifying the problem is to verify the status of the
Superloop Network card. The status of a Superloop
Network card is obtained by executing the STAT sl
command in Network and Signaling Diagnostic Program
LD 30.
Action
Log in on the MMI maintenance terminal, first as FIBER to get
into the MMI mode, and then login as HOST to get into the Host
SDI mode.
Note: If you entered the HO command while someone else is
active in the Host SDI mode, the system does not permit login
and it displays on the terminal "CONN DENIED".
At the > prompt, type LD 30 and press the Enter key to access
the Network and Signaling Diagnostic Program LD 30.
Type STAT sl and press the Enter key, where sl is the
superloop number of the Superloop Network card being tested.
If the response is UNEQ = then the superloop is not equipped
(the Superloop Network card is not installed).
If the Superloop Network card is manually disabled using LD 30,
the response can be:
