Port connections

•DT ports are used for connection to Avaya 2000 series telephones (see page 5) and support either A-Law or ∝-Law PCM encoding. Both DT and DS ports can be set for either ∝-Law or A-Law PCM encoding. At default both types of port are set to ∝-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.
