DEFINITY ProLogix Solutions Release 2 Overview 555-235-100
The DEFINITY Prologix Solutions system with Release 7 or later software can
support two C-LAN circuit packs. Each C-LAN circuit pack (TN799) can support 17
LAN ports per circuit pack. Of these ports, only one port supports an Ethernet
connection required for use with the Lucent INTUITY system. The Lucent INTUITY
system LAN link does not operate with the synchronous point-to-point protocol
(PPP) provided by the other ports. The other ports can be used for other DEFINITY
systems for PPP connections as part of a DCS network. (See Chapter 10 for further
details about DCS using C-LAN.)
The mode code (in band) link allows the Lucent INTUITY system and a DEFINITY
ProLogix Solutions system to communicate using the same analog telephone lines
that connect the two systems for call answer and message retrieval. This integration
uses touch-tone signaling, call-progress signals, and switch hook flashes over the
ordinary tip and ring analog wiring to transfer information about the telephone call
between the two systems. This integration does not require a separate link as needed
for LAN integrations.
Table 2 summarizes the features available with the different types of integrations for
DEFINITY systems.
