If I have known the the total subscriber traffic and mean holding time,how to decide how many ISUP signaling links I need? Thank you very much!!! 29th July 2002 at 15:40 #34404 Zubair A.KhurshidGuest I think it varies from switch to switch. I remeber, EWSD supports upto 2500 PSTN calls and 1200 ISDN calls with one ISUP C7 link. 31st July 2002 at 18:10 #34405 Faisal WaheedGuest Dear Zubair You must be having the calculations for the mentioned no of trunks I will look for it and let every body know. as far as I can remember it had some assumptions as well….
