Error Test
Code Result Description / Recommendation
PASS Wait 4 minutes and then check the Error Log for any new errors of type 3073. If
there are none, then both sides of the ISDN connection agree on the service
state; the negotiation succeeded. If there is a new 3073 error, then the
negotiation failed (the far-end terminal adapter twice failed to respond within
the mandatory 2-minute window). This switch will automatically retry
approximately every 15 minutes. If the port was initially in the INS (in-service)
state, it will now be placed in the MTC/FE (maintenance, far-end problem) state
(see the "Service States" section which precedes the PE-BCHL "Hardware
Error Log Entries and Test to Clear Values" table); incoming calls will be
accepted, but no outgoing calls will be originated this port. If an incoming call is
presented, another Service State audit will be immediately performed in an
attempt to bring the PRI endpoint port the proper state.
Call State Audit Test (#257)
If a call is active on the port, the switches on both sides of the connection should
agree on the ISDN state of the call as defined in the ISDN Protocol Specification.
This test audits internal call state data by querying the far-end terminal adapter as
to the ISDN state of the call. It can be helpful when trying to clear a hung call. If
the internal call state data on the near-end switch is different than that of the
far-end terminal adapter, the call will be torn down.
As with Test #256 (Service State audit), a PASS simply means that an appropriate
message was composed and sent to the far-end terminal adapter. The ISDN
Specification allows up to 2 minutes for a reply. If a reply is not received within the
2-minute window, a protocol time-out violation is recorded in the error log against
the associated signaling channel (ISDN-PRI signaling link's port, which is listed in
the Error Log as ISDN-LNK; the Error Type is 1).

Error Test
Code Result Description / Recommendation
1019 ABORT An audit is already in progress.
1. Wait 2 minutes and try again.
1113 ABORT The signaling link has failed, so the system cannot send any messages on
behalf of this port.
1. Check the results of Signaling Link State Check test (#255).
