Interface apparatus of ATM/STM coexistence network system
First Claim
1. An interface apparatus of an ATM/STM coexistence network system wherein a communication method based on an asynchronous transfer mode (ATM) coexists with a communication method based on a synchronous transfer mode (STM), said interface apparatus comprising:
- first conversion means for converting a first input signal of the synchronous transfer mode into a signal with a cell format having an additional address for the asynchronous transfer mode, and outputting said signal with said cell format as a first asynchronous transfer mode cell;
second conversion means for extracting an asynchronous transfer mode cell having a destination address from a multiplexed asynchronous second input signal and outputting said extracted asynchronous transfer mode cell having said destination address as a second asynchronous transfer mode cell; and
an output-destination controlling means for determining output destinations in accordance with said addresses shown respectively in said first and second asynchronous transfer mode cells.

Abstract
An interface apparatus of an ATM/STM coexistence network system includes a first converter for converting a first input signal of a synchronous transfer mode into a signal with a cell format having an additional address for an asynchronous transfer mode and outputting the signal with the cell format as a first asynchronous transfer mode cell and a second converter for extracting an asynchronous transfer mode cell from a second input signal in which the asynchronous transfer mode cell is multiplexed in the synchronous transfer mode and outputting the extracted asynchronous transmission mode cell as a second asynchronous transmission mode cell. The interface apparatus further includes an output-destination controller for determining output destinations in accordance with addresses shown in the first and second asynchronous transfer mode cells.
