Abstract (en)
[origin: CA2227267A1] The present invention uses digital communications over a non-telephone wiring network (220) (i.e. existing power line distribution network) to provide telephone line service to individual users (210). The telephone line service is "on-demand" in that any user can interface a telephonic device to the electrical wiring (220) and instantly obtain telephone line service. The present system may be used to provide primary telephone service and alternatively secondary telephone service for those not willing to pay for dedicated line service. For primary or secondary service, the telephone number associated with the line may be assigned by the telephone company, or utility company, or may be a uniquely assigned telephone number hardwired into each particular telephone to be connected to the electrical wiring (220). The additional "on-demand" telephone lines may be assigned an identifier, such as a suffix, for use in routing calls to and from the particular "on-demand" line.
