How 3Com Network

Director Monitors the

Phone Network

Analog Terminal Adapter and Analog Terminal Card

Each Analog Terminal Adapter (ATA) port is represented individually on the map.

The icon used for the ATA port depends on whether the port is connected to a phone or a fax.

For a 4-port Analog Terminal Card, each port uses a separate icon.

NBX Phones and Attendant Consoles

3Com Network Director detects all types of NBX phones, as well as attendant consoles.

NBX Applications

3Com Network Director also detects PCs running the pcXset (softphone client) and ConneXtions (H.323 Gateway) applications.

3Com Network Director monitors the phone network in different ways:

■NBX Call Processor: Whenever the NBX Call Processor becomes unavailable, this affects the whole phone network; all phones on the map become red, showing high stress, and a critical event is logged listing all the equipment affected. In addition, 3Com Network Director regularly polls the NBX Call Processor to check the status of the phones on the network. Whenever the status of a phone becomes offline, the phone becomes red on the map, indicating high stress, and a high severity event is logged against the phone.

■IP Phones: 3Com Network Director checks the availability of IP phones using the IP Ping Service monitor. Whenever the phone stops responding, it becomes red on the map, indicating high stress, and a high severity event is logged against the phone.

■Network Stress: Whenever an event that could impact the NBX system is logged the details for the event warn you of the devices that may be affected.
