Call State Audit Test (#257)
If a call is active on the trunk, the switc hes on both sides of the connec tion should
agree on the ISDN state of the call, as defined in the ISDN Protocol Specific ation.
This test audits internal call state da ta by querying the far-end switch as to the
ISDN state of the call. It can be help ful when trying to clear a hung call. If the
internal call state data on the near-en d switch is different than that of the far -end
switch, then
the call will be torn d own.
As with Test #256 (Service State Audit), a PASS simply means that an approp riate
message was composed and sent to the far-end switc h. The ISDN Specification
allows up to 2 minutes for a reply. If a reply is not receiv ed within the 2 minute
window, a protocol time-out violation will b e recorded in the error log against the
associated signaling channel (ISDN-LNK, Error Type 1).

Result Description/ Recommendation
1018 ABORT Maintenance is disable on this trunk.
1. Enable maintenance by entering ‘‘y’’ in the ‘‘Maintenance Tests?’’ field on
page 2 of the change trunk-group form.
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 trunk.
1. Check the results of Test #255 (Signaling Link State Check).
1114 ABORT The signaling link is in a transitional state.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
1116 ABORT The trunk is in an out-of-service ISDN service state.
1. A call cannot be present if the trunk is in an ISDN out-of-service state, so a
call state audit would be inappropriate. No action necessary. (Use the
status trunk group#/member# command to investigate the ISDN state of
the trunk).
2100 ABORT Could not allocate the nec essary system resources to run th is test.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
FAIL Internal system error
1. Retry the command at 1-minute intervals for a maximum of 5 times.
