Introduction
The QPC841 Quad Serial Data Interface (QSDI) card provides four
RS-232-C serial ports between the system and external devices. The QSDI
card plugs into a slot in the common equipment area of any system.
The Quad Serial Data Interface card is normally used to connect the system
to its administration and maintenance terminal. It is also used to connect the
system to a background terminal (used in the Hotel/Motel environment), a
modem, or the Automatic Call Distribution (ACD) and Call Detail Recording
(CDR) features.
The QSDI card is compatible with all existing system software. It does not
support 20 mA current loop interface.

NT6D39 CPU/Network module (slots 1 through 9, and 13)
•
