Introduction
The NT8D41BA Quad Serial Data Interface (QSDI) paddle board provides four RS-232-C
serial ports. These ports allow communication between the system and four external devices,
either DTE or DCE. The QSDI paddle board is normally used to connect the system to the
system administration and maintenance terminal. It can also be used to connect the system
to a background terminal (used in the hotel/motel environment), a modem, or to the Automatic
Call Distribution (ACD) or Call Detail Recording (CDR) features.
The QSDI paddle board mounts to a special socket on the rear of the backplane of the following
modules:
• NT5D21 Core/Network module
• NT6D39 CPU/Network module
• NT9D11 Core/Network module
The QSDI paddle board is compatible with all existing system software, but can only be used
with the system options listed above. It does not support the 110 baud rate or the 20 mA current
loop interface.
