Re: (ASCEND) Ascend Max T1 and FR backup

I was thinking about using BRI and connecting an ISDN modem to the WAN port
on the Maxen. Is there an ISDN modem with a V.35 connector? Though at one of
the POP's I'm already using the WAN port--on a 4048 I have CT1 going to the
two Max T1 ports and a CSU/DSU connected to the WAN port to do the FR. Is
there a BRI card for a Max 4xxx? Is it expensive?

On the P130 that you have both T1 and BRI, how do you have the routing
setup? Is it setup so that the BRI line is dialed and link established when
the T1 drops?
Thanks for your input. Any and all comments and suggestions welcomed.
