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 30), all of these
Expansion Modules are connected to the Expansion Ports of an IP Office platform using Expansion
Interconnect Cables (see page 61).

Note:
Port connections
• DT ports are used for connection to Avaya 2000 series telephones (see page 5) and support
either A-Law or µ-Law PCM encoding. Both DT and DS ports can be set for either µ-Law or A-
Law PCM encoding. At default both types of port are set to µ-Law but can be switched, in
software, to A-Law (refer to the Administration Manager Manual for details).
Using DT Line Cords (see page 56) 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 65). When devices are equipped with line
cords that terminate in RJ11 plugs, then RJ11/RJ45 adapters should be used.
