16 LinkPlexer
Getting started Standard 3.02
ICM application multiplexing
The CS 2x00/DMS lets a resource be associated with only one link session with
the switch. LinkPlexer 6.0 enables ICM applications to share, through TCP/IP,
the same session and CS 2x00/DMS resources, and manages messages to and
from the switch.
Connectivity of ICM client to CompuCALL
LinkPlexer 6.0 supports a single connection to the CS 2x00/DMS switch, either
Ethernet TCP/IP or X.25. ICM-only applications can access CompuCALL-
equipped systems through this connection. LinkPlexer relays messages to the
X.25/ICM link on the switch.
Messaging
LinkPlexer 6.0 tracks each message from an application to the CS 2x00/DMS.
The initial response message is sent only to the sending application. Event or
unconfirmed type messages are broadcast to all connected applications.
An application communicating with LinkPlexer 6.0 operates exactly as if it were
connected directly to the CS 2x00/DMS.
DN association management
LinkPlexer 6.0 keeps track of which DNs and agent position IDs are associated
with each application (such as Contact Center Manager Server or
Communication Control Toolkit). This ensures that DNs and agent position IDs
associated with a particular agent/client connection are not disassociated by a
dv-Dn-Associate (delete) message being received from another application. For
more detailed information, see Appendix D, “DN association management.”
Session management
Session management is carried out by LinkPlexer 6.0 and operates as follows:
„
On service startup, LinkPlexer establishes a connection with the switch and
starts a logon session by sending a dv-Appl-Logon message.
„
When the last application disconnects from LinkPlexer 6.0, the link
between LinkPlexer 6.0 and the CS 2x00/DMS is also disconnected. After a
short period (less than 10 seconds), LinkPlexer 6.0 reestablishes the
connection to the switch and restarts the logon session by sending a dv-
Appl-Logon message.
