Abstract

A hybrid exchange which exchanges the STM data to be transmitted periodically to realize an exchange in unit of the ATM data to be transmitted asynchronously includes asynchronous transmission terminal interface as the interface with an STM terminal, an synchronous transmission terminal interface as the interface with an ATM terminal, an ATM exchange interface as the interface with an ATM exchange, a transmitting unit for transmitting the STM time slot and ATM time slot, and a control unit for controlling the interfaces. The synchronous transmission terminal interface assigns the STM data to be transmitted periodically to the STM time slot, while the asynchronous transmission terminal interface assigns the ATM data to be transmitted asynchronously to the ATM time slot. The STM time slot and ATM time slot are identified by the STM/ATM identifier. The STM time slot is stored by multiplexing a plurality of STM data.
