Static loss pad
One of two loss pads (either long or short) can be selected on a per trunk basis.
To provide this functionality, LD 14 has to be configured with a Class of
Service of either SHL (short line) or LOL (long line). The configured pad
type is downloaded onto the XDID/DOD cards.
Disconnect supervision
To support this functionality, the software has been changed so that an XDID
card can provide disconnect supervision for a DID trunk with Ear and Mouth
(E&M) signaling. The software has also been changed to refrain from sending
an End of Selection (EOS) signal when an incoming trunk call is being
disconnected.
DID digit collection type
To support this functionality, the type of incoming DID digit collection is
configured against a Class of Service and downloaded to the XDID card.
Unsupported Class of Service
If an attempt is made to download an unsupported configuration during
regular enabling of the pack or during audit, the pack responds with a problem
report type 3 message. The error message ERR5327 is printed out on the TTY
and the trunk is disabled.
Incoming Digit collection
This functionality only applies to Dual-tone Multifrequency (DTMF) DID
trunks. The software must be ready to accept incoming digits regardless of
whether or not an “Enable Digit Collection” message is sent. To support this
functionality, the trunk must be configured with an incoming start
arrangement (prompt STRI = IMM in LD 14). Message H0019 is sent when
a Digitone Receiver (DTR) signal is found.
