GuestReply to Giora answer:
If i am not wrong:
BHCA for 16K erlang(CAT-A)=800K
BHCA for 8K Erlang switch (CAT-B)=500Kmirza
Guesthi vineet kumar,
its definations is ” if a circuit is bussy for 1 hour its mean 1 erlang traffic has been passed.”
example
if we have a average 3 mint call how much erlang has been passed is
3/60=.05 Erlang has been passed.

GuestHow we can increase ASR ?
Krishnan
Guesthi prajakta
well if i relating to your question correctly
here
BHCC = 4.8
ASR = 0.8
BHCA = ?Now the relation is
BHCC = BHCA * ASR
4.8/0.8 = BHCA
BHCA = 6alwasy BHCA > BHCC as it involves unsuccesful attempts of calls
i hope i haveinterpreted ur question rite .
