Call-by-Call
System Availability: Not available with CTX28
Program Number(s): 324 and 323
Call-by-Call service allows multiple facilities to share a PRI channel group. Traffic requirements of
different facilities vary at different times, and sharing B channels on a Call-by-Call basis makes it possible
to use fewer B channels to perform an equivalent service to the discrete counterpart.
1. Complete the
“324 CBC Time
Zones”
on
page 6-30
.
2. From the Program Menu, click
Trunk > ISDN > Call by Call. The
ISDN Call by Call Service screen

323 CBC Service
Prerequisite Program:
302
page 6-25
Call-by-Call service allows multiple facilities to share the PRI channel group. Since the traffic
requirements of each facility may vary at different times, it becomes possible to use fewer ‘B’ channels to
perform the equivalent services of the discrete counterpart. This sharing the ‘B’ channels on a call-by-call
basis can save the user money. To accomplish CBC services, each facility needs to be defined, its related
Line Group assigned and minimum and maximum values for the services provided. These service
parameters may be set for three different time zones, thus allowing fewer or more services of different
types at different times of the day. Complete the
“Call-by-Call Record Sheet”
