Feature description
The Commonwealth of Independent states (CIS) Toll Dial Tone Detection
feature allows the system to detect a dial tone from a CIS Toll Central Office
(CO) on outgoing toll calls. When received, the tone indicates that the CIS
CO is prepared to collect dial pulse (decadic) digits from system for outgoing
toll calls. The feature is implemented only for CIS DTI2 trunks.
The CIS DTD feature introduces CIS toll out-pulsing criteria, which are
terms that define conditions that need to be satisfied to allow the system to
start the out-pulsing of the decadic digits on the outgoing Toll CIS DTI2 calls
(see
The criteria is composed as a combination of two events: dial tone detection
and ANI interaction. It may include only dial tone detection, only ANI
Interaction, dial tone or ANI, dial tone and ANI. The criteria is defined at the
route data block level. The detection is performed by the CIS DTI2 cards
(NTCG01AC and NTCG02 AC) and when the criteria is satisfied the system
receives a report from the card. The system postpones the out-pulsing of
