Calculate average holding time:.
Average holding time = f6.2 x Intra) + (14.1 x outeoing)
Intra calls + outgoing calls
4Refer to Table 6-7 or Table 6-8 (at
theend
of this document) and use
answers from (2) and (3) above to determine the number of receivers
required.
Detailed calculation: method
2
This method can be used when incoming Digitone trunks are included in the
system. This method uses the same assumptions as method 1, with the
receiver holding time assumed to be 2.5 seconds for a DID call.
Procedure 3-2
Detailed calculation method 1
Calcualte Intra-office and Outgoing Digitone calls as shown in
Method 1 (1):
DID calls = 100 x Dinitone station traffic (in ccs)
call holding time in seconds
Calculate total receiver traffic:
Total receiver traffic =
1.3 x 6.2 x Intra + (1.3 x 14.1 x outeoinp) + (2.5 x DID call@
100
Refer to Table 6-9 (at the end of this document) and use the answer
from (2) above to determine the number of digitone receivers required.
