1. A method of connecting a communications device to a packet switched network, comprising the steps of:

  • initiating a Point-to-Point Protocol (PPP) session between said device and a network access server, said network access server providing access to said packet switched network for said device, said session associated with a PPP state and with a first port in said network access server, wherein said PPP session thereafter becomes dormant but said PPP state is not removed from said network access server;

    receiving, after said PPP session has become dormant, at said network access server a new call set-up message associated with said device, said new call set-up message arriving at a second port in said network access server;

    switching said PPP state from said dormant PPP session associated with said first port to a session associated with said new call set-up message associated with said device at said second port, wherein said PPP state is transferred to said session associated with said new call set-up message and the negotiation of link control protocols or network control protocols between said device and said network access server may be avoided.
