Abstract
A CPE application automatically detects an intermediate-layer protocol used at a DSL-connection head end and configures the DSL modem driver for that protocol. The application sets the driver to a possible driver protocol and attempts to connect to a head-end server. If a response is received from the head end, then the application reads the headers on the responsive message to determine whether the protocol at the head end is consistent with the protocol that the DSL modem is set to. If so, then the settings are loaded into the driver. If no response is received from the head end, then the application initiates a series of commands to elicit a response from the head end. If the protocol is not consistent or no response is elicited, then the DSL modem is set to another protocol, and the application again attempts to connect to the server at the head end.
