Abstract:
1. A telephony distribution system comprising: at least one first connector terminal with two connection points for a pair of conductors providing a telephone line and a plurality of second connector terminals with two connection points for a pair of conductors forming part of a telephony distribution installation, with each connection point of each of said second connector terminals connected or connectable to a respective connection point of said first connector terminal, which system comprises, for each of said second connector terminals, a short circuit manager including: a substitution current source; a switch having a first input terminal connected or connectable to said first connector terminal, a second input terminal connected to said substitution current source, and an output terminal connected to said each of said second connector terminals, without being connected to another second connector terminal, said switch having a first position in which said switch connects the output terminal to the first input terminal and isolates the output terminal and the second input terminal from each other and a second position in which said switch connects the output terminal and the second input terminal to each other and isolates the output terminal and the first input terminal from each other; and control means for controlling said switch to normally set said switch to said first position and to set said switch to said second position in the event of a short-circuit between the two connection points of said each of said second connector terminals.
