Problems with PPP Negotiation

Once you have a modem connection and completed the login phase, the next step in the connection phase is the PPP negotiation. The client and the server communicate to negotiate a common configuration for the PPP link. The policy is to converge if at all possible; however, failure to agree on certain mandatory parameters will cause the negotiation to fail, as shown in the following log file extract:
