hello list,
i am setting up linux with pc300 cyclades as our new FRAD device
for the frame-relay service of our internet provider.
i am using PC300/RSV (1 and 2-port model) as my comm card and a
tainet xtream base band modem. i tried both cards on 2 different
linux (mandrake 10 and LFS) using the supplied straight-through
DB25-to-DB25 and M.34 (v35) interface to the modem.
i used both the stock kernel (2.4.26 && 2.6.3-mdk) and official
cyclades drivers (bundled diskette) and their HOWTO, but then i
still not able to connect to the other end of the pvc.
on my LFS, i catch the error "hdlc0: DCD is OFF, going administrative
down" when i activated the hdlc0 interface.
might be a modem to comm port issue?
the tainet xtream base band modem is working OK with the router
being serviced to us by our provider, so i guess it must be a
configuration issue on my linux box.
any other ideas?
thank you.
below is how i configured (manually) the interface. 202.202.202.x
is not my real address though.
