Re: How many PRIs per pair of DASS-II BNCs?

Hi Alex,

A pair of BNC cables would certainly imply just the one circuit. If you
really do only have one connection then perhaps you could assume that
the DDIs on the second one are actually not being used. Perhaps you
should request details of which DDI numbers are assigned to each
circuit. DASS2 offers various features that Q.931 can't - you could have
some channels split across two DASS2 circuits sharing DDI numbers, and
then some channels on either one of the DASS2 circuits with other DDI
numbers on.
