Connecting the Six-port Line Busy Module

The optional Six-port Line Busy Module is used to simulate an "off hook" (line busy) condition when a malfunctioning COM port is detected or WorldDesk Commuter is powered off. When the Telco switch or PBX senses a line busy condition, calls are rerouted to the next available "on hook" (not busy) line.

Designed for use with WorldDesk Commuter, each line busy module supports up to six serial COM port connections. The line busy module may be installed as a table top or rack mount unit. When rack mounting the line busy module, make sure the cabinet supports 19-inch RETMA standards. Table top and cabinet installation procedures are located toward the end of this chapter.

Figure 3 - 4 shows the line busy module’s connector locations. Figure 3 - 5 illustrates connections from the line busy module to WorldDesk Commuter and external modems via the octopus, line busy, and telco cables.

For additional information on the Line Busy feature, refer to the WorldDesk System Administrator’s Guide.
