Abstract
The present subject matter relates to methods, circuitry and equipment providing a multi-functional, cost effective, media independent, open platform for communication services using differential signaling interfaces. The methods, circuitry and equipment comprise a plurality of input amplifiers, output amplifiers, and multiplexer switches or resistive dividers. which provide the ability to monitor, provide service protection switching, provide redundant services, provide on-demand service, provide service upgrades, security, test. and troubleshoot any communication devices and services.
Claims23
A system for communications networks, comprising:
- a communications device having communication circuitry comprising:
- a plurality of connections defining at least a first network connection configured to transmit and receive communication service, and a second network connection configured to monitor the communication service and to selectively inject the communication service or test signal;
- a plurality of input differential amplifiers;
- a plurality of multiplexer switchers or resistive dividers;
- and
- a plurality output differential amplifiers;
- wherein the circuitry defines a plurality of differential signal paths between the plurality of connections;
- and
- a first Small Form-factor Pluggable SFP variant device at the first connection, and a second Small Form-factor Pluggable SFPT variant device at the second connection;
- wherein each of the plurality of multiplexer switches is selectively determinative of the differential signal paths between an input path of each of the plurality of connections and an output path of at least two other connections simultaneously though one input differential amplifier, one multiplexer switch and two output differential amplifiers.
