Avaya IP Office 412 Control Unit

The IP412 Office base unit, running software level 3.0+, supports up to 360 extensions by using up to 12 Expansion modules. Connection to trunks is via a combination of any of the following integral interface modules:

• Single or Dual* PRI E1/PRIE1-R2 (30 or 60 trunks respectively).
• Single or Dual* PRI T1 (24 or 48 trunks respectively - USA only).
• (*dual PRIs can be fitted to either Slots A or B).
• Quad BRI (8 trunks) .

Dual independent auto-negotiating 10/100 Base-TX Ethernet ports provide segmented access (allows a firewall break to be used) to the LAN. (Where IP telephones are to be used a suitable LAN switch with QoS capabilities, must be used.)

Analog 4 (4 loop start trunks).

Expansion Modules

Optional analog extensions. The Expansion Modules (with the exception of the WAN3 – see below) are connected via the Expansion Port sockets that are located on the back of each unit.

Up to twelve, Office base unit provided that the maximum number of extensions does not exceed 360.

Expansion Modules allow the IP412 Office to be expanded to a maximum of 360 digital or in any combination, of the following Expansion Modules can be supported by the IP412
