ISDN-SGR (ISDN-PRI Signaling Group)
For G3r, the SYS-LINK MO reports layer-2 ISDN-PRI D-channel problems and for
G3i/s/vs, the PI-LINK MO reports layer-2 ISDN-PRI D-channel problems (if the D
channel is connected to the Processor Interface circuit pack). However, for G3i,
the PI-LINK MO does not monitor the layer-2 status of the ISDN-PRI D channel
when it is connected to the Packet Control circuit pack for the ISDN-PRI over
PACCON feature. The Layer 2 Query test is provided to detect Layer-2
D-Channel failures and generate an associated Warning alarm independent of the
hardware configuration used for the D channels.

Error Test
Code Result Description / Recommendation
1132 ABORT Internal system error:
The port location for the primary ISDN-PRI D channel is not known. This
condition should not be possible since an administered DS1 circuit pack must
be specified when a Signaling Group is administered:
1. Retry the command at 1-minute intervals up to 5 times.
1134 ABORT Internal system error:
The associated DS1 circuit pack is not administered. This condition should not
be possible since an administered DS1 circuit pack must be specified when a
Signaling Group is administered.
1. Retry the command at 1-minute intervals up to 3 times.
2500 ABORT Internal system error:
1. Retry the command at 1-minute intervals up to 5 times.
1 FAIL Layer 2 of the primary signaling channel is down:
1. Examine the results of the Primary Signaling test (#636), and follow
2. If Test #636 passes, the Layer 2 Query test may still fail if the Signaling
2 FAIL Layer 2 of the secondary signaling channel is down.
1. Examine the results of Secondary Signaling Link Hardware test (#639),
2. If tests #639 passes, the Layer 2 Query test may still fail if the Signaling

that the DS1 port used for the Primary D channel has not been busied out
