Re: Cisco BRI to Ascend Max authentication



See below:

On the BRI interface, you need to add the following command to do LQM:
	ppp quality "%"

Where "%" is replaced with the percentage of errors over which the router
will disconnect the call.

type = 0 (??)
>May 12 13:41:17 border 6145: PPP BRI1/0: B-Channel 1: rcvd unknown option
0 rejected

Type 0 is RESERVED in the PPP RFC.

Try adding the LQM on the Cisco router.  If that doesn't work, send me
email.

In the future, you might want to join and send email to one of the Cisco
lists for Cisco-specific questions:
	as5200-request@wwa.com			For AS5200 questions
	cisco-request@spot.colorado.edu	For Cisco general questions
	cisco-nsp-request@cic.net		For Cisco ISP/NSP questions
