Also, is there anybody out there who understands
frame relay over ISDN ? What's the advantage of
this versus "hard-wired" ISDN ? Is it true that
most TELCO's don't support this even if your
hardware does ? Which of the three products under
discussion supports this feature ?
Thanks / Kyle Townsend

A major point is that the BRI-channels support digital leased lines
(D64S or D128S), that means "hardwired" BRI-connection (without
D-channel signalling). A major must for ISPs especially in Germany.
This feature is an RFE from our site since we started the 5BRI/OR-ST
beta. The lack of digital leased line made many of our potential
customers go Cisco or Ascend...
(Yes, I know, I'm getting on everybody nerves at Livingston with this
RFE ;-)))
