Note: 

The IP400 Digital Terminal 16 Expansion Module is only equipped with the bottom row of 

ports (1-16). 

 

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.
