Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 207 words
A trunk extender test and monitor apparatus for central telephone equipment comprising; a trunk jack panel assembly, and a trunk test cabinet assembly, said trunk jack panel assembly comprising a plurality of jacks and a multi-terminal connector, each of said jacks being internally electrically connected to selected ones of the terminals of said multi-terminal connector, said trunk test cabinet assembly comprising a multi-terminal connector, selective switching means, and voltage measuring means, cable connecting means for interconnecting said multi-terminal connectors of said jack panel assembly and said trunk test cabinet assembly with said trunk test cabinet assembly being positionally disposed remotely from said jack panel assembly, said trunk jack panel assembly being adapted to be positioned in proximity of said central telephone equipment, each of said jacks of said trunk jack panel assembly being operable to have a trunk input from said central telephone equipment connected thereto, and said selective switching means of said trunk test cabinet assembly being operatively connected with said multi-terminal connector thereof to selectively connect each of the trunk appearances at said jack panel assembly to said trunk test cabinet assembly for test and monitoring procedures of said selected trunk remotely of its appearance at said central telephone equipment and said jack panel assembly.
Claim 2
Dependent Claim 207 words
A trunk extender test and monitor apparatus for central telephone equipment comprising; a trunk jack panel assembly, and a trunk test cabinet assembly, said trunk jack panel assembly comprising a plurality of jacks and a multi-terminal connector, each of said jacks being internally electrically connected to selected ones of the terminals of said multi-terminal connector, said trunk test cabinet assembly comprising a multi-terminal connector, selective switching means, and voltage measuring means, cable connecting means for interconnecting said multi-terminal connectors of said jack panel assembly and said trunk test cabinet assembly with said trunk test cabinet assembly being positionally disposed remotely from said jack panel assembly, said trunk jack panel assembly being adapted to be positioned in proximity of said central telephone equipment, each of said jacks of said trunk jack panel assembly being operable to have a trunk input from said central telephone equipment connected thereto, and said selective switching means of said trunk test cabinet assembly being operatively connected with said multi-terminal connector thereof to selectively connect each of the trunk appearances at said jack panel assembly to said trunk test cabinet assembly for test and monitoring procedures of said selected trunk remotely of its appearance at said central telephone equipment and said jack panel assembly.
