Signaling Link Status Test (#626)
This test determines the current status of the signaling link. This test passes if the
link is "bound" to an endpoint and fails if the link is "not bound."
The definition of the term "bound" for a link depends upon the type of endpoint
and may depend on the successful completion of procedures at both Layers 2 and
3 of the protocol. The definition of "bound" for each type of endpoint is as follows:
■
BRI endpoints administered for MIM (management information
messages) initialization (multipoint):
NOTE:
An MIM is a level 3 message that conveys management and
maintenance information between a communications system and a
BRI terminal.
For endpoints of this type, the signaling link is "bound" when the link is
connected at Layer 2 and the link has been associated with an endpoint,
[that is, the endpoint has completed SPID initialization (L3 established)].
■
ASAI adjuncts and BRI endpoints not administered for MIM
initialization (point-to-point):
For endpoints of this type, the signaling link is "bound" when the link is
connected at Layer 2 (L2 established).
For all endpoint types, a signaling link becomes "unbound" when it is
disconnected at Layer 2. For BRI endpoints supporting MIM initialization, a
signaling link may also become "unbound" if a subsequent attempt to perform
SPID initialization on a "bound" link fails, (that is, wrong SPID is entered into the
endpoint by the user).

ABORT
The Packet Bus in the port network is out-of-service.
1. Follow the repair procedures for the Packet Bus.
2. After completing Step 1, use test port long PCSSpp and review the
results of the BRI Port Local LAN Loop Around Test to verify the repair.
