Esprit 8/16 Channel

Statistical Multiplexer

User Manual

1

INTRODUCTION

The Esprit is an 8 or 16 channel asynchronous statistical multiplexer, which may be
used with Dial up Modems and Leased lines (such as KiloStream™) up to 256 Kbps in
the case of the 16 channel unit or 64Kbps for the 8 channel.

The unit is easily configured from either end of the link, using a terminal or a PC running
a terminal emulation package.

This user manual covers installation and setup of user options for the multiplexer.
A full set of cable specifications are available in the appendices.
