6/12    Do you need a CSU/DSU for an ISDN line.  If so does Pac Bell supply
        that when they install it?
        \_ yes if its a pri.. no if its a bri.. -shac
        \_ CSU/DSU is something that applies only to T1 lines.  ISDN has
           no such thing.
           \_ if you need anything, it'll be an NT1.
