Now I use 123-5ab2 for the LNS(npe-g1).
This release is sending the attribute 77 connectinfo, but in it there
is something other that I expected.
Send this for modem call : Connect-Info = "115000"
Send this for ISDN, and for Multilink ISDN call : Connect-Info = "64000"
I would like something like this for modem: Connect-Info
="48000/28800 ......." I would like to see minimum the rx,tx speed
that it gets from the LAC.
