Abstract:
A device for coupling first and second bi-directional wired digital data signals to each other and to a data unit, for use with first and second service wire pairs installed at least in part in walls within a building. The first service wire pair concurrently carries the first bi-directional wired digital data signal and a first service signal carried over a first service signal frequency band, using frequency division multiplexing. The first wired digital data signal is carried over a frequency band distinct from the first service signal frequency band. The second service wire pair concurrently carries a second bi-directional wired digital data signal and a second service signal carried over a second service signal frequency band, using frequency division multiplexing. The second wired digital data signal is carried over a frequency band distinct from the second service signal frequency band.

The device includes: a telephone connector for connecting the device to the telephone wire pair; a filter coupled to the telephone connector to pass only the digital data signal; a modem coupled for bi-directional digital data signal communication with additional modems over the telephone wire pair; a data connector for connecting to the data unit; a data transceiver coupled to effect full-duplex serial digital data communication with the data unit; a power port; and a single enclosure housing the filter, the power supply, the modem and the data connector.
Abstract:
An outlet for coupling a data unit and an analog telephone set to in-wall wiring that simultaneously carries a bi-directional serial digital data signal multiplexed with a telephone signal. The outlet includes: a wiring connector operative for connecting the outlet to the in-wall wiring; a data interface connector coupled to the wiring connector and connectable to the data unit, for coupling the serial digital data signal to the data unit; a telephone connector coupled to the wiring connector and connectable to the analog telephone set, for coupling the telephone signal to the telephone set; and a single enclosure housing the wiring connector, the data interface connector and the telephone connector, wherein the enclosure is dimensioned to be mountable into a standard outlet receptacle or opening.
Abstract:
A communication system having first and second states for use with a shared transmission line composed of at least two conductors and composed of first and second transmission line segments connected to each other at a single connection point. In the first state, a termination is coupled to the single connection point and is operative to at least attenuate a signal propagated between the first and second segments. In the second state, a driver is coupled to the connection point and is operative to conduct a signal over the first and second segments.
Abstract:
In conjunction with a data communication network (53) carrying multiple telephony signals and allowing for connection of telephone sets (17), a system and method in which two external feeders (55a, 55b) connect to the data network (53) at two distinct points via two distinct devices. The data network can be based on dedicated wiring or can use existing in premises medium such as telephone, powerlines or CATV wiring. In the latter case, the wiring can still carry the original service for which it was installed. The external telephone connections can be based on the traditional PSTN, CATV network, cellular telephone network or any other telephone service provider network, using specific adapter for any medium used. In the case of connection to a POTS telephone signal, VoIP gateway (or any other converter) is required.
Abstract:
A service outlet for coupling a data unit to a wired digital data signal and for coupling a service unit to an analog service signal, for use with a service wire pair installed in walls of a building, the service wire pair concurrently carrying a wired bi-directional digital data signal and an analog service signal carried over a service signal frequency band, using frequency division multiplexing, wherein the wired digital data signal is carried over a frequency band distinct from the service signal frequency band. The outlet has a single enclosure and, within the enclosure: a wiring connector; first and second filters coupled to the wiring connector; a service connector coupled to the first filter and connectable to the service unit for coupling the service unit to the analog service signal; a service wiring modem coupled to the second filter; and a power supply coupled to the service wiring modem.
Abstract:
An outlet for a Local Area Network (LAN), containing an integrated adapter that converts VoIP to and from analog telephony, and a standard telephone jack (e.g. RJ-11 in North America) for connecting an ordinary analog (POTS) telephone set. Such an outlet allows using analog telephone sets in a VoIP environment, eliminating the need for an IP telephone set or external adapter. The outlet may also include a hub that allows connecting both an analog telephone set via an adapter, as well as retaining the data network connection, which may be accessed by a network jack. The invention may also be applied to a telephone line-based data networking system. In such an environment, the data networking circuitry as well as the VoIP/POTS adapters are integrated into a telephone outlet, providing for regular analog service, VoIP telephony service using an analog telephone set, and data networking as well. In such a configuration, the outlet requires two standard telephone jacks and a data-networking jack. Outlets according to the invention can be used to retrofit existing LAN and in-building telephone wiring, as well as original equipment in new installation.

Abstract:
A telephone outlet simultaneously supporting both standard telephony and data communications over telephone wiring within a residence or other building. The outlet typically contains a low pass filter, connected between the telephone wiring and the telephone connector pins used for telephony (e.g. pins 2 and 3 in typical North-American RJ-11 connectors). In addition, a direct, unfiltered connection to the telephone wiring is supported via two other unused pins (e.g. pins 1 and 6 in typical North American RJ-11 6-pin connectors), thus allowing the connection of modems and high pass filters for access to the high frequency portion of the spectrum for data communications. Benefits include easy and direct connection of a telephone set or data devices to the same outlet, and elimination of the need to modify the telephone with low-pass filters or to provide an external module with a low-pass filter in series with the telephone. The direct, unfiltered connection to the telephone wiring also permits using a modified telephone having a low-pass filter, or an external module if so desired.
Abstract:
A local area network using the telephone wiring within a residence or other building simultaneously with telephony signals, with network outlets having telephone and data connectors allowing connection of Data Terminal Equipment to the network. The network outlets use high pass filters to access the high-frequency band across the media, whereas the standard telephone service uses low pass filters to access the low-frequency voice/analog telephony band across the same media. The high pass filters of the network outlets at each segment end are connected to modems or other Data Communication Equipment, thus supporting data communication networks of various topologies, including point-to-point topologies. The invention also contemplates a network outlet having a data interface connector for allowing connection of Data Terminal Equipment thereto and having a telephone connector for connecting a standard telephone thereto. A splitter is adapted to be connected to a telephone line for separating data and telephone signals transported on the telephone line, whilst a coupler is adapted to receive telephone and data signals and feeds a composite signal at an output thereof to the telephone line.
