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 26), all of these Expansion Modules are connected to the Expansion Ports of an IP
Office platform using Expansion Interconnect Cables (see page 73).

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 68) 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 77). When
devices are equipped with line cords that terminate in RJ11 plugs, then RJ11/RJ45
adapters should be used.
