Abstract
Call pick-up device for direct observation of the service of an automatic telecommunication network that executes a part of a procedure for direct observation of subscribers, characterized by connecting directly to the distributor of a telephone exchange, which can be rotary or cross-bars indistinctly, and pouring the information generated on a tape recorder controlled by the call picker itself, or on a reading device without a tape recorder, allowing the listening or recording of all the audible signals that appear in the observed circuit; retain at will, or not, the observed circuit; provoke manually, or not, the end of the observation; start the observation only when the first signaling appears on any of the circuits under observation; his indifference to incoming calls; its previous programming of periods of operation and time of each observation; detect and code the number dialed by the subscriber, the hang signal and the count pulses; identify the calling subscriber circuit; conform the level of multi-frequency signals between centrals; record the time at which the observation is made and total the number of observations made.
