Feature description

Automatic Number Identification (ANI) on Digital Trunk Interface (DTI)
extends the ANI feature to digital Central Office (DCO) and Digital Toll Office
(DTO) trunks. In addition, the ANI capability is extended to Primary Rate
Access (PRA) trunk routes through the Primary Rate Interface.

For further information, refer to the Automatic Number Identification feature
module in this guide.

Operating parameters

The QPC189F or NT817 (all vintages) are required to support this feature.

DTI interfaces externally with a digital trunk carrier facility at the DS-1 rate.
MF signals pass across this interface in a digitally encoded format.

Supervisory signaling through DTI is accomplished by A&B bit signaling.
A&B bit signaling can emulate E&M or loop signaling.

Address (called number) signaling through DTI can be dial pulse or MF.
Immediate start or wink start may be used.
