  • Patent number: 6757369
    Abstract: A voice over DSL telephone system for a customer premises. The system includes a network interface device having a DSL filter coupling DSL service from a central office to the customer premises wiring and a switch for automatically connecting POTS service from the central office to the customer premises wiring whenever there is no active integrated access device, IAD, connected to the wiring. A detection circuit detects the presence or absence of the IAD and opens and closes the switch accordingly. Both DSL and POTS ports of an IAD may then be connected to the same customer premises wiring. Telephone sets are coupled to the customer premises wiring through low pass filters which block DSL frequencies.

  • Patent number: 6711417
    Abstract: An interface between a public switched telephone network (PSTN), a wireless communication network having a plurality of cells and a plurality of mobile switching centers (MSCs), and a wireless device. The interface includes a broadband telecommunications network. It also includes an integrated services hub (ISH). The ISH is communicatively coupled to the wireless device and the broadband network. The ISH receives RF communications from the wireless device and converts the RF communications into control and data signals usable by said broadband network. The ISH has an antenna with a first coverage area extending over a pico cell. The interface also comprises a service manager communicatively coupled to the broadband network, to the wireless network, and to the PSTN. The service manager receives the control and data signals from the ISH via the broadband network and forms and provides signaling communications in response to receiving the control and data signals.
