3-16 Provisioning guidelines
Detailed calculation: method 1
This method can be used when there are no incoming
Digitone
DID trunks
and the following is assumed:
-
Receiver traffic is assumed to be inflated by 30% to cover unsuccessful
dialing attempts.
-
Call holding times used in Irma-office and Outgoing Call calculations
can be assumed to be 135 seconds if unknown.
-
Receiver holding times assumed to be 6.2 and 14.1 seconds for intra
and outgoing calls respectively.
-
Factor
(l-R)/2
in (1) Outgoing, assumes that Incoming calls and
Outgoing calls are equal. R is the intra-office ratio.

Calculate Digitone calls:
Intra-office traffic = 100 x Diaitone station traffic (ccs) x
E
call holding time in seconds 2
Outgoing traffic = 100 x Digitone station traffic
X(I-R)
call holding time in seconds 2
2Calculate total receiver traffic:
Total receiver traffic = 1.3 x l(6.2 x Irma) + (14.1 x
