A junctor for use in a time division multiplex telephone system of the kind having clock input means for establishing successive information frames each consisting of a plurality n of time slots, said junctor including: a pair of input highways and a pair of output highways, for any given two way conversation between a pair of subscribers one of said input highways and one of said output highways being provided to carry samples relating to one way of the said two way conversation and the other of said input highways and the other of said output highways being provided to carry samples relating to the other way of said two way conversation; a plurality n of stores connected in series between the said one of the pair of input highways and said other of the pair of output highways; and controllable gating means connected between each store and the next for routing samples stored in each store to the next store or to the said one of said pair of output highways.

Claim 3

A junctor as claimed in claim 1 and wherein said controllable gating circuit is controlled such that a sample relating to one way of a two way conversation is routed from said one of said pair of input highways into and through one or more of the serially connected stores to the said one of said pair of output highways whilst at the same time a sample relating to the other way of the same two way conversation is routed into and through the remaining stores to the said other of said pair of output highways.

Claim 4

A junctor for use in a time division multIplex telephone system of the type having clock input means for establishing successive information frames each consisting of a plurality n of time slots; a plurality n of input means for receiving voice signal samples from a number n of subscribers in sequence during said n time slots; and a plurality n of output means for transmitting voice signal samples to said subscribers in sequence during said n time slots, the improvement wherein said junctor comprises: a plurality n of stores serially disposed between one of said input means associated with a first subscriber whose voice signals are sampled during a time slot A and one of said output means associated with said first subscriber so as to receive voice signal samples from a second subscriber whose voice signals are sampled during a time slot B; and gating means for connecting said one input means to said further output means serially through some of said stores during time slots A-B and thereafter for connecting said further input means to said one output means serially through the remainder of said stores to establish two-way conversation between said subscribers during different time slots of each frame.

Claim 5

A junctor for use in a time division multIplex telephone system of the type having clock input means for establishing successive information frames each consisting of a plurality n of time slots; a plurality n of input means for receiving voice signal samples from a number n of subscribers in sequence during said n time slots; and a plurality n of output means for transmitting voice signal samples to said subscribers in sequence during said n time slots, the improvement wherein said junctor comprises: a plurality n of stores serially disposed between one of said input means associated with a first subscriber whose voice signals are sampled during a time slot A and one of said output means associated with said first subscriber so as to receive voice signal samples from a second subscriber whose voice signals are sampled during a time slot B; and gating means for connecting said one input means to said further output means serially through some of said stores during time slots A-B and thereafter for connecting said further input means to said one output means serially through the remainder of said stores to establish two-way conversation between said subscribers during different time slots of each frame.
