Abstract
Abstract A system for use in a telephone switching office for coupling telephone connector switches either to line group switches or to call intercept apparatus. The system includes a plurality of number terminal blocks and group terminal blocks, each of which have groups of terminal posts. Certain terminal posts of each group of the number terminal blocks are coupled to connector switches and certain other terminal posts are coupled to the call intercept apparatus. Certain of the terminal posts of each group of the group terminal blocks are coupled to line group switches. Also included is a plurality of switching tools, each of which is mounted on a different group of terminal posts of the number terminal blocks and each of which includes a first and second group of terminal posts. Included in each switching tool is apparatus for coupling certain of the number terminal block terminal posts on which the tool is mounted to certain of the switching tool terminal posts of the first group and apparatus for alternatively connecting certain other of the number terminal block terminal posts either to certain other switching tool terminal posts of the first group or to the second group terminal posts. The terminal posts of each switching tool are arranged so that an intercept tool may be mounted thereon in the same manner that such intercept tools are mounted on the terminal posts of number terminal blocks.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
288 words
In a telephone switching office, a system for coupling telephone connector switch output leads either to subscriber lines or to call intercept apparatus, the switching office including a plurality of number terminal blocks, each including a plurality of groups of terminal posts, the lower ends of certain posts of a group being connected to certain connector switch output leads identified with particular subscriber numbers and the lower ends of certain other posts of a group being connected to the call intercept apparatus, and a plurality of group terminal blocks, each including a plurality of groups terminal posts, the lower ends of some of such posts of a group being connected to subscriber lines, the improvement comprising a plurality of switching tools, each including a housing having a plurality of recesses therein for receiving the upper ends of a group of number terminal block terminal posts to enable mounting the switching tool on the posts, a first group of terminal posts extending from the housing to enable mounting an intercept tool thereon, a second group of terminal posts extending from the housing, means for electrically coupling certain terminal posts of a number terminal block on which the switching tool is mounted to certain of the switching tool terminal posts of the first group, and means for alternatively coupling certain other terminal posts of a number terminal block on which the switching tool is mounted either to certain other switching tool terminal posts of the first group or to the switching tool terminal posts of the second group, and means for coupling selected ones of the second group terminal posts of the switching tools to the upper ends of selected ones of the terminal posts of the group terminal blocks.
Claim 2
Dependent Claim
288 words
In a telephone switching office, a system for coupling telephone connector switch output leads either to subscriber lines or to call intercept apparatus, the switching office including a plurality of number terminal blocks, each including a plurality of groups of terminal posts, the lower ends of certain posts of a group being connected to certain connector switch output leads identified with particular subscriber numbers and the lower ends of certain other posts of a group being connected to the call intercept apparatus, and a plurality of group terminal blocks, each including a plurality of groups terminal posts, the lower ends of some of such posts of a group being connected to subscriber lines, the improvement comprising a plurality of switching tools, each including a housing having a plurality of recesses therein for receiving the upper ends of a group of number terminal block terminal posts to enable mounting the switching tool on the posts, a first group of terminal posts extending from the housing to enable mounting an intercept tool thereon, a second group of terminal posts extending from the housing, means for electrically coupling certain terminal posts of a number terminal block on which the switching tool is mounted to certain of the switching tool terminal posts of the first group, and means for alternatively coupling certain other terminal posts of a number terminal block on which the switching tool is mounted either to certain other switching tool terminal posts of the first group or to the switching tool terminal posts of the second group, and means for coupling selected ones of the second group terminal posts of the switching tools to the upper ends of selected ones of the terminal posts of the group terminal blocks.
Claim 3
Dependent Claim
77 words
A system as in claim 1 wherein said alternative coupling means comprises a ganged switch manually operable to either a first position in which said certain other terminal posts of a number terminal block are coupled to said certain other switching tool terminal posts of the first group, or to a second postion in which said certain other terminal posts of a number terminal block are coupled to said switching tool terminal posts of the second group.
Claim 4
Dependent Claim
181 words
In a telephone office intermediate distributing frame arrangement including a plurality of number terminal blocks, each including groups of wire terminal posts, certain posts of each group being coupled to connector switches and certain other posts of each group being coupled to telephone intercept apparatus, and a plurality of group terminal blocks, each including groups of wire terminal posts, certain posts of each group being coupled to a subscriber line, the improvement comprising a plurality of switching tools, each mounted on a different group of terminal posts of the number terminal blocks and each including a group of terminal posts, a plurality of contact elements, each of which engages a different one of the terminal posts of the number terminal block on which the switching tool is mounted, and manually operable switching means for selectively coupling certain of the contact elements of the switching tool either to the remaining contact elements of the switching tool or to the switching tool terminal posts, and means for electrically coupling the switching tool terminal posts to the terminal posts of the group terminal blocks.
Claim 5
Dependent Claim
181 words
In a telephone office intermediate distributing frame arrangement including a plurality of number terminal blocks, each including groups of wire terminal posts, certain posts of each group being coupled to connector switches and certain other posts of each group being coupled to telephone intercept apparatus, and a plurality of group terminal blocks, each including groups of wire terminal posts, certain posts of each group being coupled to a subscriber line, the improvement comprising a plurality of switching tools, each mounted on a different group of terminal posts of the number terminal blocks and each including a group of terminal posts, a plurality of contact elements, each of which engages a different one of the terminal posts of the number terminal block on which the switching tool is mounted, and manually operable switching means for selectively coupling certain of the contact elements of the switching tool either to the remaining contact elements of the switching tool or to the switching tool terminal posts, and means for electrically coupling the switching tool terminal posts to the terminal posts of the group terminal blocks.
Claim 6
Dependent Claim
