Abstract
An apparatus is provided for charging memories in a telecommunication exchange which includes line modules (LIM). These have communication paths for communication with terminals and possibly external apparatus, and have a control computer (LPU) for maintaining communication between terminals or between a terminal and external apparatus. The communication between terminals connected to different modules is set up via a digital group selector. To enable writing from a data information source (BS, TS) to all the module control computers in a single process through a module (LIM 1) selected as a main unit, the data information to be written is preceded by conditioning information (INP 1, INP 2, etc). This actuates a loading means (UPK) for establishing a connection to an addressed module (LIM 1-LIM 32) with the aid of initial information written into an unchangeable memory (MIN) in the module. Furthermore, it adjusts a decoding means (AVK) in correspondence with an identity number assigned to the module until all modules are conditioned and connected to the data information source via a common communication path. Each of the modules can only take the data information for which its deco…
