Expansion Modules
Dependent upon configuration requirements, combinations of the following
Expansion Modules are used with IP Office platforms. With the exception of the
WAN3 module (see page 41), all of these Expansion Modules are connected to
the Expansion Ports of an IP Office platform using Expansion Cables.

Port connections
• DT ports are used for connection to Avaya 2000 series telephones and support
either A-Law or µ-Law PCM encoding. At default the ports are set to µ-Law but
can be switched, in software, to A-Law (refer to the IP Office Administration
Manager Manual for details). Using DT Line Cords (see page 54) and standard
structured wiring, these RJ45 ports can be extended to the required telephone
location. In addition, converters can be used to provide BT New Plan sockets
(431A/631A) if required (see page 63). When devices are equipped with line
cords that terminate in RJ11 plugs, then RJ11/RJ45 adapters should be used.
