ECTION
When an IP telephone calls a DT300/DT400 multiline telephone, single line
telephone or trunk, the speech must be converted from IP to TDM (Time Division
Multiplexing) technology. The GPZ-IPLE daughter board provides this function.
Each GPZ-IPLE has a number of DSP resources; each can convert a speech
channel from IP to TDM and vice versa.
It is possible for DT800/DT700 IP Phones to talk directly to other DT800/DT700 IP
Phones without using a GPZ-IPLE resource. For more information, refer to

DT800/DT700 IP Multiline Telephones (ITL/ITZ)

The IP multiline telephone operates in the same way as a DT400 (DTZ)/DT300
(DTL) digital multiline telephone. It has all features and flexibility you expect from
a DT400/DT300 digital multiline telephone. The difference is that the IP telephone
has an RJ-45 for connection to an IP network, rather than an RJ-11 for connection
to a GCD-8DLCA/GCD-16DLCA.
