A modular higher density communications coupling system including a universal platform for supporting multiple connectors from a single outlet hole is disclosed. The platform includes a main body member having a registration ridge extending forward of the main body member for extending into a standard sized outlet hole. A pair of apertures adjacent to each other extend through the main body member and are generally surrounded by the registration ridge. A pair of connector housings are attachable to the rear of the platform in alignment with the apertures for housing connectors. A pair of retaining members on two sides of the apertures hold the connector housings in position. A pair of support members extend rearwardly from the main body of the platform on the other two sides of the apertures. A termination plate is mounted in the support members, the termination plate having a plurality of electrical couplings for connecting the wire from a wall to the connector. A grounding screw mount provides easy access from the front, side or rear. The relationship between the retaining members, apertures, and support members facilitates a higher density of electrical couplings than previously possible in the prior art. Telecommunications apparatus of the type identified within the specification, in combination with the aforesaid, is contemplated as coming within the scope of the present invention.

Modular higher density communications coupling system

A handheld battery-powered telecommunications test instrument for monitoring the status of a pair of wires. A tone-generating circuit generates a tone signal in response to the user manually selecting operation in a tone-generating mode. The instrument monitors the pair of wires to determine whether an on-hook, off-hook or ringing signal is present on the wires, and if present, generates an interrupt control signal through a microprocessor. Logic circuitry connected to the microprocessor results in connecting and disconnecting the tone-generating circuit and the pair of wires to selectively apply the tone signal to the wires. In response to the control signal and the user selecting the tone-generating mode, the microprocessor connects the tone-generation circuit to the pair of wires if no control signal is generated, and disconnects the tone-generating circuit if the control signal is generated. The presence of the on-hook, off-hook and ringing signals on the pair of wires is determined by measuring the voltage between the pair of wires. A menu is generated by the microprocessor from which the user can select the frequency and amplitude for the tone signal.
