420 NT7D16 Data Access card
Introduction
The NT7D16 Data Access card (DAC) is a data interface card that integrates
the functionality of the QPC723A RS-232 4-Port Interface Line card
(RILC) and the QPC430 Asynchronous Interface Line card (AILC). This
combination allows the NT7D16 DAC to work with the RS-232-C interface,
the RS-422 interface, or both.
The DAC supports up to six ports, each capable of operating in RS-232-C or
RS-422 mode. Each port supports its own parameters that, once configured
and stored in the system database memory, are downloaded to the card.
You can install this card in any IPE slot.
Features
Light Emitting Diodes (LEDs) indicate the status of the card, the call
connection, and the mode (RS-232-C or RS-422) the DAC is operating in. A
push-button toggle switch allows you to scan all six ports and monitor the
activity on each port.

• Asynchronous and full duplex operation
