The NT8D41AA Serial Data Interface (SDI) paddle board provides two
RS-232-C serial ports. These ports allow communication between the system
and two external devices. The SDI paddle board is usually used to connect the
CS 1000S, CS 1000M, and 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 SDI paddle board mounts to a special socket on the rear of the backplane
of the following modules:
• NT5D21 Core/Network module
