IP Multiline Station (SIP)
Description
The UNIVERGE SV9100 system supports DT800 IP extensions using a variety of multiline
terminals. These
telephones have the same look and functionality of typical multiline telephones,
but they are connected
to the CCPU via IP rather than by a hardwired connection to a DLC port.
Also The following DT700 IP multiline telephones (ITL) support IP extensions:
ITL-2E-1 (BK) TEL
ITL-6DE-1 (BK) TEL
ITL-8LDE-1 (BK) TEL
ITL-8LD-1 (BK) TEL/ITL-8LD-1 (WH) TEL
ITL-12D-1 (BK) TEL/ITL-12D-1 (WH) TEL
ITL-12CG-3 (BK) TEL
ITL-12DG-3 (BK) TEL
ITL-12PA-1 (BK) TEL
ITL-24D-1 (BK) TEL/ITL-24D-1 (WH) TEL
ITL-32D-1 (BK) TEL/ITL-32D-1 (WH) TEL
ITL-320C-1 (BK) TEL
IP to TDM Conversion
When an IP telephone calls a DT400 multiline telephone, a single line telephone or trunk, the
speech
must be converted from an IP to TDM (Time Division Multiplexing) technology. The GPZ-
IPLE daughter
boards provide this function. Each GPZ-IPLE has a number of DSP resources on
the blade, each one
can convert a speech channel from IP to TDM and vice versa. It is possible for
DT800 IP telephones to
talk directly to other DT800 IP telephones without using GPZ-IPLE DSP
resources.
DT700 IP Multiline Telephones (ITL)
The IP multiline telephone operates the same way as a DT300 (DTL) digital multiline telephone. The
DT700 has all of the features and flexibility you expect from a DT300 digital multiline telephone. The
difference is that the DT700 IP telephone uses an RJ-45 for connection to the IP network, rather than
an
RJ-11 connection to a GCD-8DLCA or GCD-16DLCA.
Power Save Adapter (PSA-L UNIT)
The Power Save Adapter is an add-on module for the IP (DT700) and digital (DT300) multiline
telephones. The PSA-L UNIT allows connection to an analog trunk if the power or system
connection
were to fail, or the IP telephone loses connection to the UNIVERGE SV9100 system. No
programming is
required on the UNIVERGE SV9100 to support this adapter.
Connecting to an IP Telephone
The Power Save Adapter connects to an analog PSTN (Public Switched Telephone Network) line. For
