Fault isolation procedures

Manual loopback procedure

Lightwave transceivers are not isolated as part of Expansion Interface or DS1-
CONV circuit pack tests. For example, when the Expansion Interface Lightwave 
Transceiver Looparound Test (#242) and the Expansion Interface Local Loop 
Around Test #240 pass, this indicates that the Expansion Interface circuit pack is 
functioning properly, but it does not verify that the optical portion of the lightwave 
transceiver is functioning properly.

To being the manual loopback procedure:

1. If duplicate Expansion Interface Links are available, issue the test board 

UUCSS command on the standby Expansion Interface circuit packs on 
both ends of fiber. 

2. If this test passes from both sides, but other tests fail, such as Test #241, 

this condition indicates either a faulty lightwave transceiver or a faulty fiber 
cable. To determine if either a lightwave transceiver or the fiber itself has 
failed, execute the Expansion Interface 

‘‘Manual loopback procedure’’

 

described below.

NOTE:

This test can only be run from both Expansion Interface circuit packs 
if they are the Standby pair, and if the Active pair is working properly.

Use this procedure when

■

Using DS1 CONV facilities and a 9823A lightwave transceiver.

■

An EI/SNI circuit pack cannot be tested by software. For example, an EI 
circuit pack located in an EPN that is down cannot be tested. This can 
occur when communication between the switch node carrier and the SPE 
is down.

!

WARNING:

This procedure is destructive; all calls are broken down.

To begin the manual loopback procedure:

1. Run  the configuration audit test (#759) on SNI circuit packs where possible 

with test board UUCSS s. 

2. Run the Processor Route Audit Test (#760) with the test board UUCSS 

long command for the active SNC in the switch node carrier. If the active 
SNC is not inserted, Test #760 can be run with test hardware-group pnc 
a-pnc or b-pnc.

3. Determine whether more than one SNI is unable to communicate with 

software. Verify SNI and SNC circuit pack insertion with the list 
configuration carrier UUC command and check for SNI and SNC 
insertion for every administered switch node carrier.
