administration. However, the Layer 3 test (test 637) cannot detect end-to-end transmission problems
with the Standby D-channel since Layer 3 messages are not sent on the standby channel.
The SYS-LINK Maintenance Object reports Layer 2 ISDN-PRI D-channel problems. The Layer 2
Query test is provided to detect D-Channel Layer 2 failures and generate an associated Warning
alarm independent of the hardware configuration used for the D-channels.

Description/ Recommendation
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
Media Module must be specified when a Signaling Group is
administered:
Retry the command at one minute intervals a maximum of five times.
Internal system error:
The associated DS1 Media Module is not administered. This
condition should not be possible since an administered DS1 Media
Module must be specified when a Signaling Group is administered.
Retry the command at one minute intervals a maximum of three
times.
Internal system error:
Retry the command at one minute intervals a maximum of five times.
Layer 2 of the primary signaling channel is down:
Examine the results of the Primary Signaling Test (#636) and follow
recommendations provided there.
If test #636 passes, the Layer 2 Query test may still fail if the
Signaling Channel at the far end has not been administered correctly
or if the Signaling Channel has been busied out. Verify that the
Primary Signaling Channel (D-channel) at the far end has been
administered correctly. Verify that the DS1 port used for the Primary
D-channel has not been busied out at the far end.
Layer 2 of the secondary signaling channel is down.
Examine the results of Secondary Signaling Link Hardware Test
(#639) and follow recommendations provided there.
If tests #639 passes, the Layer 2 Query test may still fail if the
Signaling Channel at the far end has not been administered correctly
or if the Signaling Channel has been busied out. Verify that the
Secondary Signaling Channel (D-channel) at the far end has been
administered correctly. Verify that the DS1 port used for the
Secondary D-channel has not been busied out at the far end.
