1. Telephone apparatus, comprising:

  • a cable television (CATV) network interface, which is adapted to be connected to a CATV network so as to receive downstream cellular telephone communication signals transmitted at a downstream intermediate frequency (IF) via the CATV network from a base-station transceiver system (BTS) operative in a cellular telephone network;

    a telephone interface, which is adapted to connect to a cellular telephone operative in the cellular telephone network via a physical connection, wherein the physical connection directly connects with internal circuitry of the cellular telephone; and

    signal conversion circuitry, which is adapted to convert the downstream communication signals received at the downstream IF via the CATV network interface to downstream radio-frequency (RF) cellular telephone signals compatible with the cellular telephone network, and to convey the downstream RF cellular telephone signals to the cellular telephone via the physical connection.
