Planning Form Instructions
1. Duplicate Form 5c, if necessary. Note that the button diagram on this
form is used as a guide for labeling the operator console buttons. You
cannot change the button assignments shown.
2 . Transfer the identification information from PBX System Form 2a,
System Numbering - Station Jacks, to each copy of Form 5c. Fill in
the "Logical ID", "Extension No.," and "Person or Location" spaces.
3. Check the box under "Adjuncts" that shows the equipment at the station.
(Refer to the Floor Plan.)
When the system is set up, users can access any trunk pool via the dial-out
code assigned to the pool. You can tailor this arrangement by restricting
telephones from making calls on specific trunk pools—for example, those
consisting of special-purpose trunks such as WATS or FX (foreign exchange).
You can also use this restriction to reserve trunk pools for data communications
only.
If you do not want to restrict trunk-pool access, continue to the "Call Restrictions"
instructions.
Planning Form Instructions
Under the "Pool Dial-Out Code Restriction" heading on Forms 4a through 5c:
1.
Check the box next to "Yes, dial-out codes."
2 .
Write the dial-out codes in the space provided. (Refer to PBX System
Form 3b, Outside Trunks - Pools for the dial-out codes.)
When the system is set up, users can place local and toll calls from all
telephones. You can restrict selected telephones from making outside calls and
allow only intercom (inside) calls—for example, telephones in a reception area
or break room. Or, to control toll abuse, you can restrict telephones from making
toll calls but still allow local and intercom calls.
