Introduction

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:
