how to calculate assumptions of 20 calls per second per ss7 link? robert 18-October-2007 04:00:15 PMComments www.unifiedcomms.com/article.cfm?id=146 - 46k - please visit Posted by waqasahmad Visit: http://www.unifiedcomms.com/article.cfm?id=146 Posted by sagitraz 1*ISUP call (5 messages * 40 bytes each on average) = 200 bytes = 1600 bits (8 bit = 1 byte) In theory 1 SS7 link data rate = 128000 bits per second (128 kps) A fully utilized signaling link can handle a call rate of = (128000*0.25)/60 = 20 calls per second In practice, with loading percentage per SS7 link is 25% for redundancy = (128000 * 0.25)/1600= 20 calls per second We dimension number of SS7 links based on calls per seconds, not circuits.
