Abstract
Kommunikasjonssystem for overforing av informasjon mellom informasjonstjeneste og tcrminalenheler over et tvunnet trådpar-nett. Informasjonstjenestene inkluderer en telefonsentral og andre tjenester, slik som et datanett og et fjernsynsdistribusjonssystem. Terminalenhetcne inkluderer telefoner og andre enheter slik som datamaskiner og fjernsynsapparater. Systemet inkluderer et hovedinformasjonsgrenscsnitt koblet til informasjonstjenestene og et tvunnet parkablingsnelt koblet til terminalenhetene og til hovedinformasjonsgrensesnittet. Kablingsncttet inkluderer et flertall aktive tclefonpar for overforing av lalesignaler mellom telefonsentralen og telefonene. Informasjonsgrenscsnittet inkluderer kretser for å kombinere, på de aktive telefonparene, (a) telefonsignalcr i et telefonfrekvensbåncl som overfores mellom telefonsentralen og den ene eller flertallet av telefoner og (b) høyfrekvenssignaler i et hoyt frekvensbånd høyere enn de for telcfonfrekvensbåndet som overfører informasjon mellom de andre informasjonstjenestene og en eller flere av Icrminalenhetene.Communication system for transferring information between information service and terminal terminal over a twisted wire pair network. The information services include a telephone exchange and other services such as a data network and a television distribution system. The terminal unit includes telephones and other devices such as computers and television sets. The system includes a main information interface connected to the information services and a twisted pair wiring harness connected to the terminal units and to the main information interface. The wiring network includes a plurality of active telephone pairs for transmitting voice signals between the telephone exchange and the telephones. The information interface includes circuits for combining, on the active telephone pairs, (a) telephone signals in a telephone frequency band transmitted between the telephone exchange and one or a plurality of telephones and (b) high frequency signals in a high frequency band higher than those for the telephone frequency band transmitting the other the information services and one or more of the ICR terminal units.
