libss7 - One linkset but 2 DPC with same CICnumber

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
