Configurable templates define VCO processing and reporting in response to the specific call progress and answer supervision events within the call model. This reduces the amount of information sent over the communications link, and, in some instances, eliminates the necessity for a host computer altogether. TeleRouter also can be used as a backup for call processing in the event of a host failure. Each switch supports up to eight hosts, providing additional operating safeguards and support for multiple applications. The systems are rigorously submitted for compliance testing and certification by national and international regulatory agencies.
All system cards are hot swappable.
Other redundancy options include main control, network control and synchronization, digital tone generation, host communication link, storage subsystem, and power subsystem. SNMP also enables direct host access to the VCO database for dynamic system configuration decision making. Alarm indications are consistent with international telecom standards. Messages can be sent to local terminals, printers, the system hard disk, the host computer, and over Ethernet via Network File System. Alarms isolate problems down to the card level including power supply and fan failures.
