COMMUNICATION OF INFORMATION VIA TWO WIRE LINES
First Claim
1. A method of communicating information via a two-wire telephone line, comprising the steps of:
- communicating information to and from a customer premises via the line using a first modem coupled to the line at an end thereof distant from the customer premises and a second modem coupled to the line at the customer premises, the first and second modems operating in a first frequency band above a frequency band for telephone signals on the line;
communicating information within the customer premises via the line using a plurality of further modems coupled to the line at the customer premises, the further modems operating in a second frequency band above the first frequency band; and
coupling information between the second modem and one of the further modems.

Abstract
Ethernet frames of information are communicated to and from a customer premises via a two-wire telephone line which can be simultaneously used for telephone signals, using a first modem at the customer premises which operates in a first frequency band above a frequency band for the telephone signals, conveniently in a half duplex manner controlled from a head end of the line to avoid collisions of Ether net frames on the line. Ethernet frames are also coupled between terminal devices within the customer premises via the same line using further modems which operate in a second frequency band above the first frequency band, conveniently also using half duplex communications controlled by one of the further modems also to avoid collisions on the line. Ethernet frames of information are coupled for example via an Ethernet hub between the first modem and one of the further modems.
