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.
QSDI cards are housed in the following modules:
• NT5D21 Core/Network module (slots 0 through 7)
• NT6D39 CPU/Network module (slots 1 through 9, and 13)
• NT6D60 Core module (slots 0 through 5)
