Avaya IP Office Phone ユーザーズマニュアル

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).

Note:  The IP400 Digital Terminal 16 Expansion Module is only equipped with the 

bottom row of ports (1-16). 

•  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.
