10 Traffic Considerations 
General 
10.1 This part details traffic limitations. Information includes: 
l Busy Hour Call Attempt (BHCA) 
l System Traffic Capacity 
l Grade of Service 
l Receiver Provisioning 
l Trunk Distribution. 
Traffic Limitations 
10.2 Traffic capacities are specified on a per line basis in terms of calls per hour, erlangs, 
and CCS. 
A basicsystem consists of 80 lines and 16 trunks. This configuration has been specified 
to meet the following heavy traffic characteristics: 
Busy...

10.4 The number of DTMF receivers required to be installed in the PABX depends on var- 
ious factors, such as the...

Traffic Considerations 
Multiple of holding time (t) = * 
h (~1 
Probability of delay greater than t (P(>t)) = I - ABSBH ii 00 
Using Erlang C formula delay curves and knowing t, A, P(>t), the minimum number of 
receivers can be obtained. 
Because the MCC II contains seven DTMF receivers, an SX-200 ML PABX configured 
at 96 ports (72 ONS and 24 digital trunks) will not require additional trunks to support 
heavy traffic.
