Note:

(a) Execute test port long location, and review the results of the BRI 

Port Local LAN Loop Around test (#618) to verify the repair.

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 every endpoint type, 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).
