Compatible System Options
Card Ports Port types 51C, 61C 81C
QPC841 4 RS-232-C asynchronous X X
QPC513 2 RS-232-C synchronous or
high-speed synchronous* X X
*See the section on the QPC513 card in this manual for details on the high-speed interface
The NT8D41BA QSDI paddle board does not use a front panel. It mounts to
the rear of the backplane in the NT5D21 Core/Network module, and does
not consume a module slot. The RS-232-C connections are brought out
through special cables to the backplane I/O panel.
The QPC841 Quad SDI card mounts in standard backplane slots and its
serial interface connectors are located on the card front panels. A list of the
modules that can be mounted in is given in the section on the individual card.
Uses
Examples of asynchronous devices that can be connected to the system
processor using the NT8D41BA QSDI paddle board and the QPC841 Quad
SDI card are:
• an administration and maintenance terminal
• a background terminal for use in a hotel/motel
• the Automatic Call Distribution (ACD) feature
• the Call Detail Recording (CDR) feature
Examples of synchronous devices that can be connected to the system
processor using the QPC513 Enhanced SDI card are:
• a host computer (DEC, Tandem, for example) using the Meridian Link
communication program
Features
The NT8D41 QSDI paddle board and the QPC841 QSDI card provide the
following features:
