October 2007 Getting started
Client connection management
LinkPlexer 6.0 manages all application connections. An application connection
is any successful socket connection to LinkPlexer 6.0. Each connection uses one
LinkPlexer 6.0 license. The number of application connections is limited, by the
keycode, to 150.
LinkPlexer 6.0 maintains the integrity of the connection between the LinkPlexer
6.0 server and each connected application. This lets LinkPlexer 6.0 free the
license when an application disconnects.
Generation of dv-Set-Offhook-U on behalf of a softphone
When a physical phoneset is used to make an outbound call, the CS 2x00/DMS
sends a dv-Set-Offhook-U message at the time the phoneset goes offhook. When
a Communication Control Toolkit-enabled softphone is used to make an
outbound call, the CS 2x00 does not sent a dv-Set-Offhook-U message.
However, LinkPlexer 6.0 generates the dv-Set-Offhook-U message and sends it
to all connected applications. For more detailed information, see Appendix G,
“Softphone message sequence chart.”
Application continuity test
Contact Center Manager Server and LinkPlexer applications both support an
application-invoked continuity test. This test is sent by Contact Center Manager
Server or LinkPlexer applications to the switch and the switch responds. This
continuity test is initiated from the opposite direction from that of a switch-
invoked continuity test but performs the same function from the perspective of
the application. In the case of Contact Center Manager Server to the CS 2x00/
DMS, the continuity test interval is 60 seconds. In the case of LinkPlexer to the
switch, you can configure the interval (default is 600 seconds). It is not
mandatory to have both a switch continuity test and an application continuity
test running.
For information about configuring a switch continuity test with X.25, see
“SCAICOMS table” on page 155. For information about configuring a switch
continuity test with TCP/IP, see “SCAICOMS” on page 161.
