In an central office, normally there is one link set that signals to a STP. There are usually multiple trunk groups that signal to many dpc's,. I have been in offices that have one link set, but signal to 20 or 30 different dpc's. So at least in the US, this is very common. /Tom chandler ----- Original Message ----- From: "Matthew Fredrickson" <creslin@xxxxxxxxxx> To: <asterisk-ss7 at lists.digium.com> Sent: Wednesday, December 12, 2007 9:29 AM Subject: Re: libss7 - One linkset but 2 DPC with same CICnumber > Daniel Bichara wrote: >> Hi, >> >> We are running libss7 with 3 E1s.
