<p>A system and method (104) for establishing a link layer connection between a calling modem having a plurality of possible first physical layer modulations and one or more possible link layer connections and an answering modem having a plurality of possible second physical layer modulations and one or more possible link layer connections include establishment of a physical layer connection between the calling and answering modems, chosen from among the possible first and second physical layer modulations by negotiation (40). A link layer connection is chosen based on the chosen physical layer modulation. The link layer connection includes parameters that are preset to default values based upon the chosen physical layer modulation (42). This serves to provide faster and more robust connection by avoiding link layer negotiation.</p> |
