3Com NBX V3000 Family Hardware

The 3Com NBX V3000 platform is a full-featured IP telephony solution designed for small and medium-sized organizations moving to a Voice over Internet Protocol (VoIP) architecture. Its ease of use allows non-technical personnel to make individual or system-wide changes with the click of a mouse. The system’s ability to scale up to 1,500 devices and
to support standards-based protocols, including Session Initiation Protocol
(SIP), gives organizations the confidence to choose the NBX solution for
their current and future telecom needs.

With a built-in analog gateway interface, the platform can connect up
to four analog loop-start central office (CO) lines directly to the Public
Switched Telephone Network (PSTN), reducing configuration time and
its related expense. Additionally, the NBX V3000 solution—in
combination with an NBX Expansion Chassis—accommodates further
communications options via T1/E1, PRI, analog and BRI trunking.
