Communication Server Directory Programming
The Communication Server programming area allows you to designate the type of interface
module that is installed in each of the module bays of the Mitel CS-5200/5400/5600 Base
Server. In addition, there is information which tells you the number of timeslots required by the
database configuration. This is done so that you are aware of the number of timeslots in use by
the system. Although the basic system configuration is non-blocking, certain configurations can
lead to circumstances wherein more timeslots are assigned than are available, which may result
in blocking if an attempt is made to use all resources at once.
For more about time slot allotment, refer to the Specifications chapter. In addition to the
Processor Module (PM-1), Base Server modules can be installed in any of the three available
bays. The Digital Expansion Interface supports modules that cannot be installed in the Base
Server.
Modules available for installation include the T1/E1/PRI, Dual T1/E1/PRI, the two-port/four-port
Loop Start (LSM-2/LSM-4), four-port Single Line Module (SLM-4), and two-port Basic Rate
Module (BRM-S) [European market only]. Program these fields to identify which type of module
resides in each bay.

For more information about system modules, refer to the Specifications and Installation
chapters.
When changing the module type, existing circuits must first be reconfigured. Not redefining the
associated circuits before inserting another module type of a different device type produces an
error message. The fields used in Communication Server programming include the following.
They are described in detail in the following text.
• Module Bays (3)
• Loop Start Ports
• Single Line Ports
• Processor Module
• Processor Expansion Card (optional or included with CS-5400)
• DEI-1, 2, 3, and 4
• Error Thresholds
