Using a single node at 100% CPU capabilities and 100 % utilization for the SS7 links ,please provide performance numbers in terms of voice messages per seconds and BHCA "Busy Hour Call Attempt" that the system can handle for the following scenarios

Average voice message duration
20 sec
30 sec
40 sec
50 sec
60 sec

Please state the characteristics of the CPUs used for these benchmark tests.

i have a statistical result for BHCA toatl per subs and BHCA Mobile pe subs in several hour of one day,and i need to know how to calculate the BHCA per subs,for me i think the average is the correct value,but other's think that the we must take the biggest BHCA
thanks for ur time and ur help

hi prajakta

well if i relating to your question correctly


BHCC = 4.8
ASR = 0.8
BHCA = ?

Now the relation is

4.8/0.8 = BHCA
BHCA = 6

alwasy BHCA > BHCC as it involves unsuccesful attempts of calls

i hope i haveinterpreted ur question rite .

How we can increase ASR ?

Prajakta - 24th January 2007  (07:10 GMT)

10,000 subscribers are connected to an exchange.If the exchange is designed to achieve a call completion rate of 0.8 when the busy hour calling rate is 4.8, what is the BHCA that can be supported by the exchange?

hi vineet kumar,
its definations is " if a circuit is bussy for 1 hour its mean 1 erlang traffic has been passed."
if we have a average 3 mint call how much erlang has been passed is
3/60=.05 Erlang has been passed.

Reply to Giora answer:

If i am not wrong:
BHCA for 16K erlang(CAT-A)=800K
BHCA for 8K Erlang switch (CAT-B)=500K
