a pri is a combination of isdn DS0 lines..
a BRI is 2
a pri is 23/30 ...depending on where you are
these are the data lines...
there are signalling lines aswell 64 whole ds0 for pri 16k part of ds0 for
bri.
the pri works in the same fashion...with some slight config changes..
with a pri ...you can...
load balalnce over multiple lines/part of each line(50% of line 1 brings in
line 2)
you can have multiple remote bri`s going to one pri.
you can have voice and video over different lines
there is a difference that the interface pri is a DB16 connector not rj45
on my routers i have configured 8 bri`s as subint`s to one site (fractional
PRI)
and the rest as seperate bri`s going to seperate sites....
