CIRCUIT ARRANGEMENT FOR TELECOMMUNICATION SWITCHING SYSTEMS, ESPECIALLY TELECOMMUNICATION SWITCHING SYSTEMS, WITH DETECTING METER DEVICES FOR DETECTING REQUIREMENTS.

摘要

1. Circuit arrangement for telecommunication exchanges, especially telephone exchanges, with counting devices (X, Y, Z) for registering processing requests issued to a processing network, which counting devices, according to a percentage transmitted to them by a traffic measuring device, effect a rejection of a corresponding portion of these processing requests, wherein the counting device, restricted in its counting volume by a number of counting steps, contains means (C, G) by means of which it is incremented (e, g) for every processing request (a, L) by a number of counting steps which is obtained as a product in each case on the one hand from the percentage (c1, ... cn, g1 ... gm) of the processing requests to be rejected in the current operating status in question, and on the other hand from the total number, corresponding to the counting volume, of counting steps, and wherein the counting device contains means (R, S) which, when its counter status reaches the counting volume, cyclically increment the counting device in the overflow over the zero state, and cause said counting device to issue a command for rejecting a processing request each time an overflow occurs.
