US 2005/0105472 A1 · Test access matrix (TAM) protector module and associated circuitry for a telecommunications system

Abstract

A Test Access Matrix (TAM) system permits installation onto an existing connector block. The TAM system exhibits a configuration that permits installation on to telecommunications circuits at the connection point provided for installation of protection modules or other devices that are inserted into the telecommunications circuit. The installation can be accomplished either before new or after existing connector blocks are installed on a telecommunication cross connect frame, tie frame, or other support structure. The TAM system can be instructed to connect a two or four wire test bus to any of the individual telecommunications circuits that are connected to the connector block. The test bus can be connected to the individual communication circuits in either a bridging, break towards the distribution side of the local loop, break towards the telecommunications equipment, or an insertion into the line via a “make before break” sequence. The bus can be further redirected to multiple test or monitoring devices.

Dependent claims

A Test Access Matrix (TAM) system operable with a connector block of a telecommunications system for testing telecommunications lines connected to the connector block, which comprises:

a motherboard mountable on the connector block, the motherboard having at least one first connector mounted thereon and a test bus electrically connected to the at least one first connector;
at least one TAM module having an electrical circuit, the at least one TAM module having a second connector mounted thereon which is electrically connectable to the at least one first connector mounted on the motherboard and to the test bus;
a control matrix, the control matrix being electrically connected to the at least one first connector of the motherboard and therethrough being electrically connectable to the at least one TAM module, the control matrix providing a matrix output signal to the at least one TAM module for selectively placing the electrical circuit of the at least one TAM module in a normal operating mode and at least one test mode;
and
a controller, the controller being responsive to an input control signal and generating a controller output signal provided to the control matrix, the control matrix providing the matrix output signal to the at least one TAM module in response to the controller output signal received thereby.
