Avaya IP Office 403 Control Unit

The IP403 Office base unit, running software level 3.0 , supports up to eight digital and two analog telephones. This can be expanded, by use of 3 additional extension modules, to a max. of 100 extensions.

The IP403 Office base unit is equipped with DS ports that support Avaya 24xx, 44xx, 54xx and/or 64xx telephones. These ports can be set for either mu-Law or A-Law PCM encoding. At default DS ports are set to mu-Law. However, these can be switched in software (refer to the Administration Manager Manual for details).

Connection to trunks is via any of the following integral interface modules:-

• Single PRI E1 (30 trunks) or Single PRI T1 (23B 1D or 24B trunks - USA only)
• Quad BRI (8 trunks) or Analog 4 (loop start trunks).

An eight port auto-negotiating 10/100 Base-TX LAN hub provides access to networks and/or up to eight IP telephones. (Where IP telephones are to be used, the hub should be connected to a suitable LAN switch with QoS capabilities.)

Expansion Modules

Optional Expansion Modules allow the IP403 Office to be expanded to 100 extensions. These modules (with the exception of the WAN3) are connected via the Expansion Port sockets that are located on the back of each unit. Up to 3, in any combination, of the following Expansion Modules can be supported by the IP403 Office base unit.

IP400 Digital Station 16/30

Two variants of 16 or 30 extensions for digital telephones. Hence, if all 3 extension modules are IP400 Digital Station 30's, then the maximum of 100 extensions will consist of 90 digital extensions, plus the base unit's 2 analog extensions and 8 digital extensions.

IP400 Phone 8/16/30

Three variants (8, 16 or 30 extensions) for analog telephones. Hence, if all 3 extension modules are IP400 Phone 30s, then the maximum of 100 extensions will consist of 90 analog extensions, plus the base unit's 2 analog extensions and 8 digital extensions.

IP400 So8

An S-bus module that provides 8 Basic Rate ISDN interfaces.

IP400 WAN3

Provides support for a further 3 digital leased line (WAN) connections. These expansion modules are connected to the IP403 Office unit via one of the LAN Ports located on the front of each unit.
