Calculations with Centralized Attendaht Service (CAS)
This method is used to determine the DTR requirements for the main
location of a system equipped with the CAS option. The following is
assumed:
-
All attendant calls presented through Release~Link Trunks’ (RLT) from
a remote PBX require Digitone Receivers.
-
The average number of digits dialed is 4.
-
Average receiver holding time is 6.2 seconds.
Procedure 4-l
Calculations with CAS
1 Calculate the attendant calls from the remote PBX:
attendant call = 100 x attendant traffic from the remote (CCS)
attendant work time (in seconds)
2Add the attendant calls to the intra-office calls calculated in (1) of
Method 1, and proceed with the remaining calculations of Method
1.
