Abstract
In the inventive circuit arrangement and appertaining method, data of at least respectively one ISDN data connection, a traditional telephone connection as well as of a broadband data connection are transmitted in an SDSL frame of an SDSL data connection, where the necessary control data are suitably transmitted in the overhead of the SDSL frame.
Claims17
A circuit arrangement, comprising:
- a transmission unit for inserting data belonging to at least two terminal equipment types or services that are capable of including both voice and data in a common frame having a frame length, said transmission unit comprising an insertion mechanism for inserting said data of the at least two terminal equipment types, said data of all terminal equipment types being synchronously inserted into said common frame with a common channel for operational control and transmitted with a digital time-division multiplex technique.
A circuit arrangement, comprising:
- a reception unit for dividing a datastream transmitted in a common frame with a common channel for operational control, said common frame comprising data belonging to at least two terminal equipment types or services that are capable of including both voice and data, said data of all terminal equipment types being data synchronously inserted into said common frame with a common channel for operational control, by a transmitter to at least one terminal equipment type of said at least two terminal equipment types;
- and
- a switch module for a purpose-conforming division of said data stream synchronously transmitted in said common frame, in which a further division onto further terminal equipment of said at least two terminal equipment types or services is undertaken based on control data.
A method for transmitting a data stream in a common frame with a common channel for operational control belonging to at least two terminal equipment types or services that are capable of including both voice and data, comprising the steps of:
- synchronously inserting data of said at least two terminal equipment types or services into said common frame in a first unit;
- transmitting said data to a second unit with a time-division multiplex method;
- and
- dividing said data stream in said common frame to terminal devices of at least two terminal equipment types or services in said second unit.
