Network-based
Telephony
3Com Networked Telephony Solutions merge telephony with networking
by delivering business telephone service over a data network.
To the telephone user, an NBX Telephone is a typical office telephone. You
can use it to make and receive calls, transfer calls, park calls, use voice
mail, and so on. Inside, the NBX Telephone is an Ethernet device that can
communicate over the LAN using Ethernet frames or, with the optional
upgrade, IP packets. The telephone also serves as an Ethernet switch or
hub (depending on the model of telephone) for your computer. You can
connect your computer network interface card (NIC) to your network
(LAN) through the telephone and avoid the need for a second LAN
connection at the desktop.
The core of 3Com Networked Telephony Solutions is the Network Call
Processor (NCP). The NCP manages the processes of making and
receiving calls, providing voice mail and auto attendant services, and
responding to requests for special services, such as access to the
NBX NetSet administration utility, Computer Telephony Integration (CTI)
services, or the system’s IMAP (Internet Message Access Protocol) server.
