Acknowledge - CIDCW
The TLE monitors for a DTMF “D” as an ACKnowledge digit. This is the Bellcore specified
digit expected from a non-ADSI device. The TLE will also monitor for an alternate DTMF
ACKnowledge digit, which is programmable. The default value is a DTMF “A”, which
corresponds to the Bellcore specified digit expected from an ADSI device. The ETSI
requirements state that a DTMF “D” must be accepted as a valid ACKnowledge digit, but
that “A”, “B”, and “C” may be considered valid digits in some networks.
