Introduction
The Digital Line card is a voice and data communication link between the
system and Digital Telephones. It supports voice only or simultaneous voice
and data service over a single twisted pair of standard telephone wiring.
When a digital telephone is equipped with the data option, an asynchronous
or synchronous terminal or personal computer can be connected to the system
through the digital telephone.
IMPORTANT!
The NT8D02 digital line card is supported in CS 1000S, CS 1000M, and
Meridian 1.
The NTDK16 digital line card is supported ONLY in the Chassis system.
