Switch Connectivity; High Availability Network; Autostart Software - Nortel CallPilot Install Manual

16 Chapter 2 Introduction

Switch connectivity

Both CallPilot servers have a DS30 connection to the switch. As a result,
the number of MGate cards required in the switch is double the number
required for a single CallPilot server. For a pair of servers providing 192
channels, the switch must have a total of 12 MGate cards installed (six
MGate cards per 192 channels times two servers). At any one time only one
of the two CallPilot servers is up and running. Therefore, even though there
are 384 channels configured on the switch, a maximum of 192 channels are
available for call processing at any one time.

High Availability network

The following figure shows the network containing the two High Availability
servers (CallPilot 1 and CallPilot 2).
