TL;DR: In this article, an economic time switch with high flexibility to a traffic variation among bearer signals is presented, in which a channel memory capable of sequential writing and random reading and a converter for converting a data read from the channel memory to a universal signal in accordance with a conversion mode designation.

TL;DR: In this article, a trans-multiplexer arrangement for interconnection of a time division multiplex line and a packet multiplexer was proposed, in which the trans-operator converts data for each of a plurality of terminals on the time division MULE in the unit of a packet, for allocation on the packet MULE line, and a section which identifies the time position of each data unit on the TDM line, prepares a specific packet containing the position information and allocates the specific packet before the data packet on the PULSE line.

TL;DR: In this paper, the authors propose to attain communication between lots of media by coupling a communication processing means provided corresponding to media by means of a common signal means and providing media converting function to at least one communication processing mean.

TL;DR: In this paper, the authors propose a service receiving system whose profitability and flexibility to addition of service are high, by providing newly connected service receiving device which is connected to a subscriber by a switchboard in accordance with a specified number from the subscriber, sends out an inductive guidance to the subscriber and receives each service request signal element which follows said guidance and analyzes it, and has a final service request informing function to the switchboard concerned.

TL;DR: In this article, a digital signal produced at a random pattern generating circuit 17 is applied to a callout signal pattern eliminaing circuit 18, and after the same digital signal as the callout signals are changed into other patterns, it is transmitted to a subscriber circuit via the link.
