5.4.5 Alarm Events, Route Alarms and External Control Relays
Each configuration may be set to run another configuration on a specified
fault condition. The condition can be set to be the failure of an incoming
PCM stream or a fault on a channel card which must exist for a period
defined within the 'Mode Install' menu.
Up to eight circuits may be identified as 'Route alarms' for use by the NCS
for re-routing purposes. They have no use in non-networked mode.
Four relays are provided on the 3200 for control of attached equipment.
These relays may be set to operate as required for different configurations.
