3.16 Integrated Call Costing
Call costing provides a means of establishing costing that the system can apply to outside calls made from
system telephones. Call costing computes charges for a call after it is completed. It does not restrict
dialing as toll restriction does. The system provides several ways of establishing call costing that are as
follows:
·exception tables for local and long distance calls,
·office code band tables for local calls,
·zone call band tables for long distance calls,
·area...

Example A For Local Dialing Sequence(201-nnnn)
For this example, assume that you have installed the digital telephone system in a location where callers
have an opportunity to dial number combinations that contain a common sequence in both the area and
office code.
The illustrated sequence is a local call (less than 10 digits) and 201 is the office code. Program call rate 18
to cost calls of this sequence. Also program the office code band table by assigning office code 201 into
band one. Note that the...

Example B For Long Distance With Office Code Dialing Sequence(1-201-201-nnnn)
The illustrated sequence is a long distance call (more than 10 digits) with 201 as both the area code and
the office code. Program call rate table 25 to cost calls of this sequence. Also, program the zone call band
table by adding office code 201 to area code 201 in band one. Add any other office codes (for example
478) to area code 201 in band one as required.

Example C For Long Distance Dialing Sequence(1-201-nnn-nnnn)
This illustrated sequence is a long distance call (more than 10 digits) with 201 as the area code. Program
call rate table 11 to cost calls in this sequence. Also, program the area code band table by adding area
code 201 to band one.
