A call processor in an exchange requires 120 ms to service a complete call. What is the BHCA rating for the processor? If the exchange is capable of carrying 700 Erlangs of traffic, what is the call completion rate? Assume an average call holding time of 2 minutes.
Call service time= 120ms
BHCA-(60X60)/ (120X10-3)=30,000
th =holding time 2 minutes
Ao=mean effective traffic carried through the network=700 Erlangs
Ao==Co X th ,
Here
Co=mean effective traffic rate
Therefore Co = Ao/ th =700/2 per minute= 21,000 calls per hour
Therefore total call attempts in Busy Hour= 30,000
And number of successful calls= 21,000
So, CCR= 21,000/30.000 = 0.7
