DSS1 is the signalling for ISDN in europe (not the physical standard, but
the protocol signalled on the ISDN D channel).

Wikipedia says that this is also called "net3" on BRI and "net5" on PRI
(which is what you'll see in "isdn switch-type ..." config on cisco),
but it's still DSS1...

So: DSS1 is *not* the same as "ISDN PRI", but on an ISDN PRI, one of the
possible D-Channel signalling protocols could be DSS1.
