Abstract
Abstract A circuit arrangement for transmitting synchronously and asynchronously occurring data is described. The synchronous data are transmitted using a plesiochronous, synchronous data transmission system. Additionally, at the send side, a submultiplexer receives asynchronous data and transmits that data synchronously with the send-side clock signal to the send-side multiplexer. The aforementioned transmitted data are received at a receive-side multiplexer and coupled to a receive-side submultiplexer for transmission to receive-side subscribers. Both submultiplexers operate in accordance with identical clock signals.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
164 words
Apparatus for transmitting synchronously and asynchronously occurring data, comprising: send-side multiplexer means having at least two inputs, at least one of which is connected to receive synchronous data, and an output coupled to a transmission link, receive-side multiplexer means having an input coupled to the transmission link and at least two outputs, first and second autonomous clock generators connected, respectively, to said send-side and receive-side multiplexer means for timing the operations of the multiplexer means, send-side submultiplexer means having inputs connected to receive asynchronous data and an output coupled to an input of said send-side multiplexer means for emitting thereto the asynchronous data in synchronized form under the control of a first clock signal from said first clock generator, and receive-side submultiplexer means having an input connected to receive the asynchronous data in synchronized form from said receive-side multiplexer means and under the control of a second clock signal from said second generator for emitting the asynchronous data in asynchronous form to receive-side subscribers.
