Federal Communications Commission (FCC) Compliance for DID
Answer Supervision
If FCC Compliance for DID Answer Supervision (FC68) package 223 is
configured on XFCOT units, it may lead to incorrect call status. Therefore,
equipping the FCC package is not recommended.
Trunk Failure Monitor
As part of the Trunk Failure Monitor feature, the BAR/UNBAR messages
received from IPE XFCOT trunks are treated in the same manner as the EPE
Line Break Alarm/Line Break Alarm Clear signals are treated for EPE trunks.
When a BAR message indicating a problem situation is received, a trunk
message is printed on the TTY, the uppermost key lamps light up on the
Attendant Console, and the trunk is placed into 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 message is
printed on the TTY, the lamps on the Attendant Console are darkened, and
the seized trunk is idled. Note that BARA Class of Service must be
configured on the trunk for the described processing to occur.
UK XFCOT (NT5K18AA)
For the UK XFCOT card, the NT5K18AA, there are no changes in
configuration and operation except in the following areas:
• For static pad setting, the configuration for short line and long line has
been changed from TRC to SHL for short line, and NTC to LOL for long
line.
• The PPM configuration is done on a per route basis.
• Only one value is now downloaded for the PPM ID, on all UK cards.
• Only COT trunks are supported on the NT5K18AA. The NTAG04AA
card supports COT and DID trunks.
• The balance impedance may now be configured on the NT5K90AA
(Danish PPM) or NT5K90BA (Danish non-PPM) card.
