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.

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.
will you plz tell me the exact figure.30th September 2004 at 21:35 #37059S.VijayGuest

why there is 7 in “SS7”. i mean what is the significant of this number seven here?26th October 2004 at 11:57 #37066PeterGuest
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 SS7.22nd November 2004 at 17:26 #37067ChuckGuest
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!5th January 2005 at 23:54 #37068albinoGuest
1. SS7 Link (64k) Load calcualtion
MSU = 0-272 Octets
IAM = 100 Octets max.
40% load on one link
10,080000 octets/hour (load/link
20,160,000 octets/hour (load/2link
100 IAM (octets)
201,600 IAM/Hour (/2links)
To be engineered for :
max. 0.4 Erl. /link (40%load)
up to 0.8Erl. in case of failure
17,231 trunks (ds-o) …. ex.
12,062 trunk usage
3,600 call sec.
43,422,120 call sec/h
200 average holding time
217,111 total attemps/h
15,631,963 octets/h (sig.load ds0)
100 IAM (octets)
156,320 IAM/h(generated by a ds0)
SSP ——— STP ———- SSP
| link link |
voice trunks ( x DS0)6th January 2005 at 06:37 #37069mohsinGuest
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?
