After you have completed the preplanning tasks described in
You Begin'', you can plan the control unit configuration. Planning the control unit
configuration consists of the following tasks:
1. Planning Module Placement. Calculate the systems line/trunk and
extension capacity according to the number of module types; then map out
the placement of the modules on the Control Unit Diagram.
2. Recording System Operating Conditions. Note the systems type of
programming equipment, mode and language choice, and whether the
Automatic Maintenance Busy feature is to be enabled or disabled.
3. Numbering the System. Decide the order in which to connect the
telephones and other equipment to the control unit based on the customers
needs and applications. Determine whether the system-assigned
extension numbers are appropriate for the customers business or if they
need to be renumbered.
This chapter contains instructions for completing each of these tasks.
Planning Module Placement
In addition to the processor module and power supply module, the system
supports several types of line/trunk and extension modules. Deciding how to
place the modules in the carriers consists of the following tasks:
1. Calculating the systems line/trunk capacity according to module types
2. Calculating the systems extension capacity according to module types
3. Mapping out module placement on the Control Unit Diagram according to
specific guidelines
This section contains instructions for each of these tasks.
