Planning Form Instructions
Complete the "Button Diagram" section of each copy of Forms 4a, 4b (front
and back), 4c, and 5b (back only).
Note: The button diagrams for DLCs (the back of Form 5a and the front of
Form 5b) will be completed later.
1. Show the types of System Access buttons, by writing "SA Voice," "SA
Ring," "SA Originate Only," "Shared SA," "Pool," or "Personal Line" on
buttons 1 through 10.
For a Shared System Access button, include the extension number of
the primary button owner. (Refer to Form 2a.)
For a Pool button, include the pool's extension number. (Refer to
Form 3b).
For a Personal Line button, include the telephone number and, for
future reference, record the trunk numbers (Refer to Form 2c.)
2 . Assign Loudspeaker Page buttons by selecting the butoon and writing
"Page" on it.
Use these instructions only if the system has one or more direct-line
consoles.
The line buttons automatically assigned to DLCs are different from those on
other telephones. In typical systems, DLC operators are responsible for
handling all incoming calls. Therefore, the factory setting for DLCs is that, in
addition to a System Access Voice and a System Access Ring button, as many
trunks as possible are assigned to each console. Each trunk appears on a
separate button, which means that the number of trunks assigned is limited to
the number of buttons on the console (up to a maximum of 32 on the 34-button
analog DLC).
The system also assigns a Direct Station Selector (DSS) button for each
extension number associated with a station and special-feature buttons that are
used by the DLC operator for call handling.
The number of line, DSS, and feature buttons assigned depends on the type of
telephone and the number of trunks connected to the system.
The figures that follow show initial trunk and feature assignments for digital/lSDN
(MLX) and analog DLC consoles. See the appropriate figure as you decide trunk
assignments for DLCs.
