Abstract
A communication system is provided. It comprises a central office (CO) of a communication service provider and at least one subscriber premise (SP), each SP being linked to a CO by a subscriber-associated communication line comprising a twisted pair of telephone lines, and at least one xDSL modem in the CO coupled to said subscriber-associated communication line. Each SP has a plurality of communication devices, which comprises one or more telephone devices connected to the communication line and at least one network DSL (NDSL) modem associated with a computerized device, the NDSL modem being connected to said communication line; each of said modems having an upstream transmitter and a downstream receiver for communication with the CO and an upstream transmitter and an upstream recevier for communication with other NDSL modems within the SP. Provided is also a novel NDSL modem for use in the above system there are a plurality of communication devices comprising one or more telephone devices connected to the communication line. Each of the NDSL modems having an upstream transmitter and a downstream receiver for communication with the CO and an upstream transmitter and an upstream receiver for communication with other NDSL modems within the SP. Provided is also a novel NDSL modem for use in the above system.
