Definitions
- the present invention relates in general to communications systems and more specifically to a communications system using hybrid- fiber coax networks.
- Digital communications are becoming increasingly important and prevalent in all aspects of life.
- PC personal computer
- One approach to an in-home network uses much of a home's existing telephone wiring to permit an ethernet-type network over the existing wiring. Connections to the wiring by devices within the home can be made via the existing telephone jacks (e.g., RJl 1 connectors).
- One popular standardized approach is known as the Home Phoneline Networking Alliance (HomePNA). See, for example, www.homepna.org for more information.
- HomePNA has the advantages that the wiring is often already in place so that multiple connectors are present in different rooms.
- telephone devices and connectors are standardized - a single connector type is used for almost all devices and connections.
- the existing wiring can also be used to support fairly high local data rates.
- the present invention provides an efficient and flexible interface for adding new lines and services to a home phoneline network by using the limited existing hardwire lines in a home.
- the home phoneline network is adapted to a hybrid- fiber coax link to an external communications network such as the Internet.
- a telephony device is provided that allows multiple devices to connect to a single standard telephone jack. Digital data communication is multiplexed over existing wiring and demultiplexed at a receiving unit. This provides for easy addition of virtual telephone "wires" to customer premises as the customers order additional services, lines or features.
- a preferred embodiment of the invention provides a hybrid-fiber coax Internet Protocol (IP) telephony device that supports multiple phone lines without requiring new telephone wires to be installed.
- IP Internet Protocol
- One embodiment adapts an integrated HomePNA interface in a communications gateway to support a standard connector, such as an RJl 1 connector, for connecting to existing home phone wire.
- the first telephone line can be with traditional analog signals compliant with today's telephones.
- the second, third and higher lines can be achieved by sending digital voice packets over the HomePNA network to HomePNA receivers plugged into wall jacks. Those receivers translate the HomePNA signals to traditional telephone signals to support traditional phones.
- Another embodiment is a system providing communications interconnectivity.
- the system includes an analog communication line; a communications gateway coupled to the analog communication line, wherein the communications gateway converts between analog signals and digital signals; one or more digital communication lines coupled to the communications gateway; and one or more user interfaces coupled to the digital communication lines.
- the HomePNA interface could also be used to carry information other than voice. It could carry video, audio, data, FAX information, control information for home automation, etc.
- Fig. 1 shows a system-level block diagram using the present invention.
- overall communications system 100 includes primary communication networks IP network 110 and telephone network 108. These are, for example, the Internet and the standard public telephone network. Note that any manner of primary communication networks can be included in the overall system. For example, the cellular telephone network, radio-frequency, microwave, or other communication networks can be included.
- IP Network 110 includes Call Management System 102 and Operation Support System 104 to symbolically represent additional infrastructure to handle, for example, voice-over-IP telephone calls over the Internet, billing, provisioning, etc., of Internet resources.
- Gateway 106 allows the transfer of digital information from the Internet to the analog or digital telephone system so that telephone calls can be made to and from user telephones 114.
- Network Management System 116 handles other Internet functions.
- Cable Modem Termination System 112 provides for transfer of information from the Internet to a cable network, such as a cable television network.
- the cable network includes hybrid fiber-coax lines 120 that are used to distribute digital information to homes, businesses or other destinations (i.e., "end-points") and sources of information.
- Interface 118 is the subject of the present invention.
- interface 118 provides for the transfer of information between the hybrid fiber-coax network and devices at the end-point such as device 120.
- Device 120 can be a telephone, computer, peripheral, set-top box, or any of many other devices that send or receive information.
- the devices are either standard telephone handsets or devices which comply with the HomePNA standard for digital data transfer over a home network. Fig.
- FIG. 2 shows subsystems of interface 118 of Fig. 1.
- information modulated by an rf carrier is transferred to and from hybrid fiber-coax as indicated at 202.
- Tuner/ Amplifier 206 can be a two-way data communication device.
- Cable modem 208 is used to send and receive digital data to the hybrid fiber-coax link.
- Bus 230 provides a communications path for cable modem 208, random access memory (RAM) 210, non- volatile memory (NVMEM) 212, processor 214, subscriber line interface circuit 216, digital signal processors 220 and other devices (not shown), as desired. Transfer of information can be under the direction of processor 214, any of the devices shown, by a bus master (not shown), or by other means.
- RAM random access memory
- NVM non- volatile memory
- Standard RJl 1 telephone jacks are provided so that digital and analog telephone equipment can be connected to the interface.
- a wide variety of other devices can be coupled to the interface via the jacks.
- any device supported by the HomePNA standard can be attached to the interface.
- the interface can also be designed to support other standards or custom communications and devices.
- a preferred embodiment of the invention is designed to handle a single analog and multiple digital voice communication lines.
- An analog line can be connected via jack 226.
- SLIC 216 and other subsystems within interface 118 convert the analog voice information to digital information for transfer within the home network or to the external network.
- Digital devices including telephones, can be connected via jack 228 to HPNA interface 224.
- Codecs 218 and 222 act to encode and decode digital information.
- DSPs 220 can process the digital information before transfer.
- digital telephone devices and other digital devices such as computers, peripherals, consumer electronics, etc.
- HPNA interface 224 and connectors 228 can be connected to the interface via HPNA interface 224 and connectors 228.
- the original analog telephone line is still preserved via SLIC 216 and connectors 226. All of the benefits of HomePNA networking can be achieved while still maintaining the original analog line and providing for additional digital telephone lines without requiring additional wiring at the end-point location.

Abstract
Un dispositif de téléphonie PI hybride fibres-coax prend en charge des lignes téléphoniques multiples sans nécessiter l'installation de nouveaux câbles téléphoniques. Un mode de réalisation adapte une interface HomePNA intégrée dans une passerelle de communication afin d'accepter un connecteur normalisé, tel qu'un connecteur RJ11, pour la connexion à un câble téléphonique domestique existant. La première ligne téléphonique peut avoir des signaux analogiques classiques compatibles avec les téléphones actuels. Les seconde, troisième lignes et au-delà peuvent être obtenues par envoi de paquets vocaux numériques par le réseau HomePNA à des récepteurs HomePNA branchés dans des prises murales. Ces récepteurs traduisent les signaux HomePNA en signaux téléphoniques classiques afin d'accepter des téléphones classiques.
