IPCP (PPP) doesn't seem to work on serial port

Hi,

I’m replacing our Airlink Ravens with GX400’s. The serial port of the Raven connects to the serial port on a Cisco router. The router initiates a PPP session (via a chat script) with the Raven, and during the IPCP phase the Raven provides the IP address to the router’s serial port.

However, when I connect the new GX400, the IP address is not getting transferred from the GX to the router serial port. Using debug mode on the Cisco I can see the GX400 entering PPP mode but IPCP fails after that.

I can supply more detailed logs if necessary. Has anyone else come across this. Any ideas? I don’t think it’s the router because it works fine with the Raven and the config is fairly simple. Both the Raven and the GX400 run ALEOS (different versions).

SOS. Thanks…Ron
