[souleymane kante <kante@globeaccess.net>]

Hi
I have to setup cisco 3661 as NAS; It has 16 analog modem card plug in.
When PPP clients dial in the PPP session failed most of time. the
connections is not establish . When It succed , the client is
authenticate with a remote RADIUS serveur. The authnetication is OK. But
the problem is on the PPP level.

1) I have noticed that when the connection failed , the modem debug give
me this:
02:33:27: Modem 2/0 Mcom: in modem state 'Dialing/Answering'
02:33:27: Modem 2/0 Mcom: in modem state 'Incoming ring'
02:33:29: Modem 2/0 Mcom: in modem state 'Waiting for Carrier'
02:33:39: Modem 2/0 Mcom: in modem state 'Connected'
02:33:39: Modem 2/0 Mcom: CONNECT at 300/300(Tx/Rx), BEL103, Normal,
None, Answer
02:33:40: TTY65: DSR came up
02:33:40: tty65: Modem: IDLE->(unknown)
02:33:40: TTY65: EXEC creation
02:33:40: TTY65: set timer type 10, 30 seconds

THE SPEED IS 300/300

2) when it success
02:31:09: Modem 2/0 Mcom: in modem state 'Dialing/Answering'
02:31:09: Modem 2/0 Mcom: in modem state 'Incoming ring'
02:31:12: Modem 2/0 Mcom: in modem state 'Waiting for Carrier'
