Operational data input into telecommunication exchanges or terminals - involves conversion between formats of data received or transmitted over wireless link to remote operation unit

摘要

The remote operation unit (FB) incorporates a transmitter (FBS) and receiver (FBE) with wireless links to their counterparts (E, S) at the exchange (VA) or terminal (EG) where a data format converter (FU) is connected through system interfaces (SS) to a memory (HSP). A remote display (AE) is associated with a selection keyboard (WT) and function keys (FT). The format conversion may be performed by either a custom circuit or a microcomputer able to serve a wide variety of exchanges or of programmable terminals. -
