• Static Loss Pad Selection. Trunk pad selection controls transmission
loss. A pad may be inserted within or outside an XFCOT trunk card to
allow a call to terminate on a station or another trunk. Two pad types are
available to support long line or short line. The pad types are configured
in LD 14 on a per unit basis, against a Class of Service of SHL for short
line or a Class of Service of LOL for long line. The SHL or LOL is
downloaded onto the XFCOT card.
• Enabling and disabling of Periodic Pulse Metering (PPM). The user
configures PPM on a per route basis; the software configures the trunk
on a per unit basis.
• Enabling and disabling of Buffered Periodic Pulse Metering (PPM), on a
per trunk basis.
• A PPM ID that designates PPM parameters. This is configured in LD 14
against the PPID prompt. This value is downloaded onto the XFCOT
firmware so that the appropriate PPM parameter may be selected.
• A four-unit card. The NT5K71AA four-unit quad density card has been
introduced to meet German requirements.
• Mixed Central Office Trunk and Direct Inward Dialing on the same
XFCOT card. In LD 14, the XFCOT card may be configured as being
either COT or DID.
• ALS signaling. ALS, available only on the NTAG04AA (Dutch DID/
COT) unit, is combined COT/DID signaling performed on Existing
Peripheral Equipment (EPE) COT trunks having ground start signaling.
Additions to the ground start signaling have been added for the new
XFCOT support. On the near end, a partial release message is sent
instead of a full release message. On an outgoing call, the number
reception is accepted and interpreted by the software. Number reception
is a battery reversal signaling from the CO, indicating that it has received
sufficient dialing information. The ALS signaling type is configured in
LD 14 against the SIGL prompt.
