The standard application for the paddle board is to connect the switch to
the system console. This can be either a direct connection if the console is
located near the switch, or through a modem for remote maintenance.
Bell 103/212 compatible dumb modems are recommended to connect a
remote data terminal. If a smart modem (such as a Hayes modem) is
used, configure the modem for the dumb mode of operation (Command
Recognition OFF, Command Echo OFF) before connecting the modem
to the asynchronous port.
The serial data interface connectors on the paddle board are not RS-232-C
standard DB-25 connectors. The NT8D84AA interface cable is used to
adapt the paddle board to a non-standard pinout DB-9 connector (normally
located on the I/O panel). The NT8D93 cable is then used to connect
the non-standard DB-9 connector to a peripheral that uses a RS-232-C
standard DB-25 connector. See

The NT8D41BA Quad Serial Data Interface (QSDI) paddle board provides
four RS-232-C serial ports. These ports allow communication between
the Meridian 1 system and four external devices, either DTE or DCE. The
QSDI paddle board is normally used to connect the Meridian 1 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:
