Abstract:
A broad bandâ€”narrow band connection node unit for communicating digital data between a narrow band network and a broad band network in an encoding/decoding format that is the same as an encoding/decoding format used on a communication route in the narrow band network in an integrated network composed of the broad band network and the narrow band network, comprising:at least one encoding/decoding unit having a digital one-link function that causes compressed digital data to be passed or to be decompressed only at a communication termination point depending on a setting of the compressed digital data so as to prevent a quality of the digital data from deteriorating; an individual encoding/decoding format managing unit storing the relation between each destination route in the narrow band network and formats of said encoding/decoding unit used on each destination route; and an encoding/decoding unit selecting unit asking said individual encoding/decoding format managing unit the format of the encoding/decoding unit corresponding to the destination route information included in signaling data and selecting one of said encoding/decoding unit corresponding to the obtained format.
