Description
The Digital Line Card is a voice and data communication link between the
system and Meridian 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.
In Option 11C systems the NT8D02 Digital Line Card is installed in slots 1
through 10 of the main cabinet, or in slots 11 through 50 in the Expansion
cabinets. In Option 11C Mini, the NT8D02 DLC can be installed in slots 1 to
3 in the main chassis, or in slots 7 to 10 in the chassis expander.
