Abstract:
1. A telephone switching system comprising: a plurality of line packages; and a switch unit allowing a path to be established between ones of said plurality of line packages, wherein each of said plurality of line packages includes a broadband-adaptive line package interconnected to a broadband network or a broadband-adaptive apparatus and adaptive to both of a first voice coding rule expected of said switch unit with respect to input data and a second voice coding rule having a higher compression ratio for voice coding than the first voice coding rule, wherein said broadband-adaptive line package comprises a setting circuit for monitoring a voice coding rule of another of said plurality of line packages, which is connected to said broadband-adaptive line package via said switch unit, based on information received via said switch unit, and wherein if said another line package is adaptive only to the first voice coding rule, said setting circuit conditions circuitry of said broadband-adaptive line package for the first voice coding rule, and, if said another line package is adaptive to both of the first voice coding rule and the second voice coding rule, said setting circuit condition circuitry of said broadband-adaptive line package for the second voice coding rule.
