What is a bridge tap?
A bridge tap (or bridged tap, or star wiring) is an unterminated or unused branch of a telecommunications circuit. When a junction is installed in the telephone circuit to provide an additional outlet somewhere else, a bridge tap is created.
Bridge taps are detrimental to data services delivered using xDSL technology as used by the majority of nbn™, and all ADSL services. The unused circuits act as antennas, channelling radio frequency into the circuit which adds noise to the line. The added noise on the line then causes a reduction in the achievable data rate (speed) of the circuit, and also causes dropouts.
A data circuit for xDSL should be straight. A node at one end, and a modem at the other. There should be no other branches or circuits or sockets connected to the circuit.
We can locate and remove any bridge taps or star joins from your internal wiring that may be causing dropouts or slow speeds. We use the same test equipment that the nbn™ technicians use.
- Isolate and test service at entry point
- Locate and remove any bridge taps on the internal cabling
- Provide compliance certification for remediated internal wiring
