Introduction

The QPC513 Enhanced Serial Data Interface (ESDI) card gives the CS 1000S, CS 1000M, and Meridian 1 switch two fully synchronous high-speed serial ports.

These high-speed synchronous ports are used to connect the processor to synchronous communication peripherals such as Meridian Mail or to a host computer (for example, DEC or Tandem) using Meridian Link. This card cannot be used as an asynchronous port or to connect to an administrative and maintenance terminal. Use either the NT8D41 SDI paddle board or the QPC841 Quad Serial Data Interface card to connect the switch to an asynchronous serial peripheral.
