Evolution from circuit-switched to IP
The Avaya DEFINITY® Enterprise Communications Server G3r has been the flagship product
in the DEFINITY family of communications servers. As technology changed, Avaya was able to
leverage the rapid advances in microprocessor technology to increase the capacity and
processing power of the traditional DEFINITY platform (
Figure 32: Traditional DEFINITY
configuration
) to benefit our customers.

Avaya also has the objective to protect our customers’ communications investment in the Avaya
DEFINITY platform by helping our customers leverage their existing investments in Avaya
solutions. Upgrading allows a customer to make a smooth transition to IP Telephony technology
without sacrificing the features or reliability of their current DEFINITY. A customer can make
small incremental investments to move from the circuit-switched world to a full IP PBX while
retaining their investment in TDM-based equipment and connections. On the endpoints, moving
to IP Telephony allows simplified moves, adds, and changes. It also simplifies the building
wiring plan by sharing one Ethernet connection with both the IP Telephone and the desktop PC.
It also adds IP mobility while retaining the rich set of DEFINITY features. For both IP Telephone
and traditional circuit-switched telephone users, migrating to IP Telephony offers the opportunity
to bypass tolls, and route traditionally metered long-distance calls across an unmetered IP
network instead, saving operational costs.
With the S8700 Multi-Connect solution, Avaya is delivering a high-capacity server and a
migration path from DEFINITY. The S8700 Media Server uses an industry-standard Linux
operating system on an industry-standard server, which enables all endpoints to use
Communication Manager. This solution allows customers to migrate to IP Telephony and to a
higher performance processor without sacrificing the reliability of the G3r platform.
