Avaya Definity (Also known as Lucent Definity) is a modular, circuit-based PBX system. It uses the Linux operating system via a media server.

The system is cabinet based and can be either a single carrier cabinet (SCC) or a multi carrier cabinet (MCC). The SCC’s contain 14 slots and can support up to 120 users. The MCC’s, when linked, provide a large mainframe. They bring together around 200 slots and support up to 650 users.

The Avaya Index is a modular system with a flexible communications platform. Like the Avaya Definity, it is a cost effective system, with the option of upgrading, rather than replacing, the existing infrastructure. Obtaining further features and services is possible via the addition of key codes, software upgrades and modules.

The Avaya IP406 Office system has eight digital station ports for 2400, 4400, 5400 and 6400 Series phones (plus 3810 and 9040 models). Avaya IP Office 500 is a modular unified communications platform designed to meet the requirements of small and medium sized organisations.

MF Communications stocks a wide range of parts and accessories for both popular and rare legacy Avaya systems. All new and remanufactured parts and phones are rigorously tested and come complete with a full one year warranty.
