Figure 79: Remote Layer 3 Query Test (#637)
For systems supporting circuit packs (S8700, S8500) Figure 79 illustrates a UDS1 Interface
circuit pack located in the PN. When the UDS1 board resides in a PN, there is additional PNC
hardware connecting the packet buses of the IPSI PN and PN. Examples of such hardware are
the Center Stage Switch and fiber-optic cables.

ABRT Internal system error.
1. Retry the command a 1-minute intervals up to 5 times.
1006 ABRT There are no associated B channels in an ISDN in-service or maintenance
service state.
For country protocol 1 interfaces (including the USA), either there are no
B-channels administered in this signaling group, or all B-channels in this
signaling group are either out-of-service or are in a “pending” state (PINS or
PMTC, indicating that a B-channel maintenance message for that B-channel
has been sent and not yet acknowledged).
This is a NORMAL ABORT.
1. Administer or release an ISDN trunk or PRI endpoint before retrying the
test. For an ISDN trunk, use status trunk grp#/mem# to verify the
ISDN trunk state. For a PRI endpoint use status pri-endpoint
extension. Then, retry this test when at least one B channel is in the
in-service or maintenance states.
For systems not using country protocol 1 interfaces, there are no B-channels
administered in this signaling group.
1019 ABRT There is already a Remote Layer 3 Query in progress. This is a normal
ABORT.
1. Wait two minutes, then follow the procedures for when this test passes.
