How 3Com Network
Director Monitors the
Phone Network
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.
