Endpoint Errors
Endpoint is in RESTRICTED mode (ENDPT IN RESTRICTED SVCE)
When the MERLIN LEGEND system is initializing an endpoint, it sends an
initialization request message, which contains the Service Profile Identifier
(SPID), to the CO. If the SPID is invalid, the CO sends back a message that the
endpoint is in RESTRICTED SERVICE mode. In this mode, the CO usually blocks
any outgoing calls. When this error is received, the technician should verify the
SPID and reprogram it.
Endpoint establishment failed (LINK ESTABLISHMENT FAIL)
When this message is received by the MERLIN LEGEND system, the link
establishment request has failed. In other words, the link was not established
before the associated timer expired. Either there is a problem with the port on
the 800 CO-BRI module or the line has not been properly activated by the CO.
Endpoint uninitialized (ENDPOINT UNINIT L2/L3)
When Layer 1 is up but Layer 2 and/or 3 is down for an endpoint, this error is
logged. If this error does not disappear, there is a problem either with the port or
at the CO.
Network took endpoint
This error is logged when the MERLIN LEGEND system tries to put an endpoint
in service and the network responds by taking it out of service,
SETUP and RELease Message Errors
Network not responding to a SETUP message
(NW NOT RESPOND TO SETUP)
Network not responding to a RELease message
(NW NOT RESPOND TO RELEAS)
If the MERLIN LEGEND system sends a SETUP or RELease message and the
CO does not respond with the appropriate message before the BRI timer
expires, the system sends the message again, If the CO still does not respond in
time, the system tears down the call and logs this error,
