Except for the WAN3 10/100 module, the IP Office 406 V2 supports six expansion modules and the IP Office 412 supports twelve expansion modules. The WAN3 10/100 differs in that it connects to the control unit via a LAN port rather than one of the rear expansion ports. A maximum of 2 WAN3 10/100 modules are supported on the IP406 V2 and IP412 - they are not supported on the IP Office - Small Office Edition.
This module provides additional two-wire analogue telephone interfaces (POT ports). The Avaya IP Office 400 Phone V2 module is available in 3 versions, giving 8, 16 or 30 extensions. Telephones can be located up to 1km from the control unit - for cabling details please see the IP Office Installation Manual. For extensions located "out-of-the building" additional line protection will be needed.
This expansion module provides additional Digital Station (DS) ports for supported 2400, 5400 and T3 Series phones plus 3810 wireless phones. The Avaya IP Office 400 Digital Station V2 module is available in 2 versions; 16 or 30 extensions.
Telephones can be located up to 1km from the control unit - for cabling details please see the IP Office Installation Manual. For extensions located "out-of-the-building" additional line protection will be needed.
Note that if EU24 or EU24BL units are being used with IP phones, as maximum of eight are supported on the whole system.
The Avaya IP Office 400 So8 module provides 8 S-Bus interfaces for Basic Rate ISDN devices.

The IP400 Office WAN 3 10/100 module provides three WAN connections (X21, V35 or V24 via a 37way D Type socket and using an appropriate connector cable). Line speeds up to and including 2Mbps are supporting on each interface, the carrier providing the line dictates the actual operating speed i.e. in some territories the maximum speed may be 1.544M. These interfaces are identical to the single connection provided as standard on the IP406 and IP412 platforms.
The IP400 Office WAN3 10/100 may be connected to the IP406 and IP412 platforms to provide additional WAN ports. Each platform, except Small Office Edition, can support up to two WAN3 10/100 modules.
The IP400 Office WAN3 connects to the base unit through the Local Area Network via a 10/100Mbps connection and does not use an expansion port on the control unit.
