ISDN Call-by-Call
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 6-37.
2. Select Trunk > ISDN Call by Call.
3. Enter Channel Group number.
4. Enter Program 323 data.
5. Enter Program 324 data.
6. Click Submit.
323 CBC Service
Prerequisite Program: 302 page 6-30
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.
