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
