A method, apparatus, and software for providing lifeline service during power failure affecting Customer Premises Equipment (CPE) in a Digital Subscriber Loop (DSL) arranged to carry voice traffic in band rather than on a separate analogue POTS band. The arrangement provides a reduced service, capable of supporting at least one voice call, to operate during such power failure and, where a single call is in progress during power failure, that call may be maintained during the transition from DSL to analogue POTS lifeline service. Where a call is in progress upon power restoration, the lifeline POTS service may be maintained until completion of the call so as not to interrupt a potential lifeline call.

An in-floor, flush poke-through wiring fitting may be installed in the floor of a structure to enable the activation of power, communication, and/or data services at the fitting location. The poke-through fitting includes a height adjustable mounting bracket that provides for internal mounting of a variety of different low voltage data jacks (e.g. fiber optic, RJ-45 Category 5, coaxial, etc.). The mounting bracket includes a first portion that is mountable in the finish ring over an internal chamber of the poke-through fitting. The data jack is mounted in a second portion of the mounting bracket that is mountable in the bracket first portion in a height adjustable manner, whereby the height of the bracket second portion may be adjusted relative to top assembly to accommodate service connectors of varying heights.

A connector includes a locking mechanism that locks the connector in a socket but allows removal of the connector without a manual operation that relies on depressing the locking mechanism. The connector is released from the socket when a sufficient pulling force is applied to the connector. The connector includes a spring-loaded detent that flexes during the insertion process. The detent snaps into a locking position. The detent can be released from the socket when sufficient tension is applied on the connector such that inadvertent tension will not result in breaking the connector.

A plug locking assembly comprises at least one plug holder comprising opposing top and bottom arms, said top and bottom arms extending tranversely from a wall and defining open spaces therebetween, said open spaces for receiving and holding plugs. The plug holders are typically positioned adjacently to one another or in tandem and the configuration of the opposing top and bottom arms allows for side installation of plugs. The plug locking assembly may further comprise a cover overlying the plug holders.

A method and system of enabling incoming and outgoing call capability for a digital telephone that is limited to analog transmissions include providing a converter that locally supports the protocol of the digital telephone, but that converts digitized signals of voice information, party-specific call messages and call-handling call messages into outgoing analog signals. In one embodiment, one analog signal carries the voice information and a second analog signal carries the party-specific and call-handling call messages, with the first analog signal being transmitted via a public switching telephone network and the second analog signal being transmitted via a data network. Received analog signals are reconverted to digital signals having the appropriate protocol. In another embodiment, the voice information, the party-specific call messages and the call-handling call messages are transmitted along a single digital link between two converters, typically by means of a data network.

A device for preventing unauthorized access to female modular telephone jacks. A physical plug has been designed such that when it is inserted into an RJ-11, RJ-14, or RJ-45 modular telephone jack, it locks into place and cannot be removed without the use of a specialized tool. The specialized tool then acts as a key to unlock the plug. Several different pairs of plugs and corresponding tools have been created such that there are different `locks` and `keys`.

Apparatus for providing an ISDN to analog interface

An interface which includes a MIDI send terminal having first and second pins for providing an output signal, an RS 232 terminal having first and second pins for receiving a signal from the MIDI send terminal, apparatus for coupling any MIDI output signal to the RS 232 terminal, the apparatus for coupling including apparatus for shifting a base level at which the signals are presented at the MIDI terminal to a base level at which the signals are received at the RS 232 terminal, apparatus for shifting the voltage swing of signals presented at the MIDI terminal to a voltage swing at which the signals are received at the RS 232 terminal, and apparatus for disabling the RS 232 terminal if a device to which the RS 232 terminal is connected would normally respond in an undesirable manner to unexpected data received on the RS 232 terminal.
