Federal Communications Commission (FCC) Compliance for DID
Answer Supervision
If FCC Compliance for DID Answer Supervision (FC68) package 223 is
configured on XDOD units, it may lead to incorrect call status. Therefore,
equipping this package is not recommended.
Trunk Failure Monitor
As part of the Trunk Failure Monitor feature, the BAR/UNBAR messages,
received from IPE XDID trunks, are treated in the same manner as the EPE
Line Break Alarm/Line Break Alarm Clear signals are treated for EPE trunks
(LD 15 must be configured with TFDR = YES). When a BAR message
indicating a problem situation is received, a TRK501 message is printed on
the TTY, the uppermost key lamps light up on the Attendant Console, and the
trunk is placed in the BUSY state to prevent the trunk from being seized for
new outgoing calls. The reception of an UNBAR message indicates that the
problem situation has been cleared. A TRK502 message is printed on the
TTY, the lamps on the Attendant Console are darkened, and the trunk is idled.
