Claims23
A customer bridge comprising:
- a housing having snap-in features for attaching said housing to a network interface unit, said housing including:
- first and second network terminals for coupling to first and second network lines;
- first and second customer terminals for coupling to first and second customer lines;
- a single pole, manually operable switch having first and second switch terminals, said second switch terminal being connected to said second network terminal;
- and
- an energy detecting device coupled in series between said first switch terminal and said first network terminal, wherein closing of said manually operable switch results in connecting said first network terminal to said second network terminal via said energy detecting device and said manually operable switch.
3 more elements
A network interface unit comprising:
- a plurality of customer bridges, with each customer bridge including a housing attached to said network interface unit, each housing including:
- first and second network terminals for coupling to first and second network lines;
- first and second customer terminals for coupling to first and second customer lines;
- a single pole, manually operable switch having first and second switch terminals, said second switch terminal being connected to said second network terminal;
- and
- an energy detecting device coupled in series between said first switch terminal and said first network terminal, wherein closing of said manually operable switch results in connecting said first network terminal to said second network terminal via said energy detecting device and said manually operable switch.
