Hello Pankaj,
Could you please explain me the following:
“If you are using the SS7 links for ISUP, a general rule of thumb is to have 40E1s, per pair of SS7 links.”
it will be of great F1.
-Thanks
HariHi all,
I have Erlang table. With this table is possible calculate number of trunk.
Regards
PeterHi Peter,
I have ERLANG TABLE but it is normal one.
If you have some extra features with ERLANG Table ..then send me a copy to scorplund1976@yahoo.com

A single ss7 link can handle how many E1 links,with ISUP an ISUP call is usally made up to five messages of 40Bytes each on average.

why there is 7 in “SS7”. i mean what is the significant of this number seven here?
ITU (previous CCIT) had defined a few signalling systems (Nr. 5,6 etc.) Last version of signalling-SS7 had number in orded 7.
I think it is meaning of number 7 in own name SS7.Hi all,
can someone help me figure out how to calculate the number of ss7 links required per BHCA at the A-interface(MSC-BSC) and the c-interface (MSC-STP)?Thanks!

I have a questions regarding your SS7 calculation.
1. How octet in IAM messages counted?
2.Why only IAM, not till RLC?
3.you used 64Kbps as reference, but in culcation you used 56000 b/s?rgds
