Abstract
A long-distance transmission system includes a network terminal that accommodates terminal equipment, and a line terminal connected to the network terminal via a two-wire metallic subscriber line. The network terminal includes an amplifier, which amplifies a transmission level of a transmission signal to be transmitted to the line terminal via the two-wire metallic subscriber line on the basis of a characteristic of the two-wire transmission line.
Claims31
A long-distance transmission system comprising:
- a network terminal that accommodates terminal equipment;
- and
- a line terminal connected to the network terminal via a two-wire metallic subscriber line, the network terminal comprising an amplifier, which amplifies a transmission level of a transmission signal to be transmitted to the line terminal via the two-wire metallic subscriber line on the basis of a characteristic of the two-wire transmission line.
A network terminal connectable to a two-wire metallic subscriber line, comprising:
- a transmission circuit that outputs a transmission signal;
- and
- an amplifier part which amplifies a transmission level of the transmission signal which is to be sent to the two-wire metallic subscriber line.
