The various line interfaces work together seamlessly to allow any combination of audio

channels to be connected to a server.

A Truelog server is not limited in the number of channels it can handle, but is rated in

accordance with the number of concurrent channels that can be recorded (up to 480 per

server).

This is a function of the server’s CPU processing capability, which is scaled in accordance

with traffic requirements.

Above 480 channels, multiple-server ‘Cluster’ configurations permit scaling to any number of

concurrent channels.

A server cluster configuration allows fully transparent working, including multi-site

distributed servers within a WAN environment.
