Feature description
The Commonwealth of Independent states (CIS) Toll Dial Tone Detection
feature allows the Meridian 1 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 Meridian 1 for
outgoing toll calls. The feature is implemented only for CIS DTI2 trunks.
The CIS DTD feature introduces CIS toll outpulsing criteria, which are terms
that define conditions that need to be satisfied to allow Meridian 1 to start the
outpulsing of the decadic digits on the outgoing Toll CIS DTI2 calls (see
Figure 23).
