A Plain Old Telephone System (POTS) connection is established between a Broadband modem and a remote server. A configuration request is then transmitted from the Broadband modem to the remote server using DTMF tones. Subsequently a domain name associated with a Broadband Service Node (BSN) and a user identifier, such as a telephone number, is received from the remote server via the POTS connection using Dual-Tone Multi-Frequency (DTMF) tones. A PPPoE session is then established using the domain name, by firstly authenticating the Broadband modem for the PPPoE session and then configuring the DSL modem. This configuration is accomplished by transmitting a request for configuration details from the Broadband modem to the BSN having the domain name and then receiving configuration details from the configuration server. The Broadband modem then automatically configures itself using the configuration details.

A method of producing hydrocarbons from a well. The method begins by injecting steam into a well. The bitumen in the formation is then heated with the injected steam, followed by ceasing the injection of steam into the well and then by soaking the bitumen with the injected steam and collecting the heated oil. Steam that has condensed is revaporized by directing RF / MW radiation to the steam allowing for more bitumen to be produced without injecting more steam. In addition, some of the steam could become superheated, wherein the temperature of the superheated steam is greater than the temperature of the steam. The bitumen is heated by the revaporized steam and the superheated steam, followed by soaking the bitumen with the revaporized steam and the superheated steam. Hydrocarbons are then produced from the well.
