System division multiplex switching time (MDT) specially designed for telephone signals modulated pulse code (mic).

摘要

A switching system (TDM) FOR MAKING CONNECTIONS CHOSEN AMONG MANY NUMBERS LINES AND LINKS AND MAY COMBINE IN AN INTEGRATED, MISCELLANEOUS SYSTEMS SWITCHES (TDM) THAT ARE REACHED TO MANAGE SMALL NUMBER OF LINES AND LINKS AS enlarging THE CAPACITY TDM smaller systems. The system has a modular construction, DISTRIBUTED, WHICH ARE THE LINES AND LINKS ACFOPLADOS into a plurality of fields. FIELDS each have a link controller connecting the PCM FIELDS BETWEEN CAMPOS VIAS. FIELDS each include how its members, a plurality of devices. These members DEVICES MAY BE SHIPPED BETWEEN PHASES CONNECTING LINES AND TELEPHONE LINKS AND BECOMES telephone analog signals into signals PCM and vice versa CIRCUITS perform services, such as ring tones, CONFERENCE FACILITIES DTMF TONE DUAL (DTMF), PROCESSORS TELEFONICOS CONTAINING THE DATA BASE OF SPEECHES (TELEPHONE NUMBERS) multiline and links, SOUNDS AND DEVICES GENERATING INTERFACE PROVIDING FOR AN ENTRY VIA SIGNALS IN THE FIELDS FOR MINORS TDM switching systems. Each field has its own channel PCM INTERIOR TO WHICH ARE CONNECTED DEVICES. Each field can have a different SUPPLEMENT devices. MODULAR DEVICES ARE interchangeable. Communicates STRUCTURE OF CONTROL SIGNALS CONTROLLING THE TELEFONICA PROCESSED SIGNAL ALONG separate rings, unique to each device, such devices CONNECTING LINK CONTROLLER. Signaling messages are communicated to each FIELDS ALONG TIME CHOSEN LINES IN A SERIES OF CYCLIC IN TIME LINES BETWEEN THE FIELDS AND ROADS ON device controlling the links connecting devices to link controllers. The device contains GENEREADORES DIGITAL SIGNAL FOR GENERATING MESSAGES SIGNALING AND COMMUNICATION OF THEM ON CONTROL DEVICE RINGS TO THE DRIVER LINKS AND medante CONTROLLER LINKING AND LINES OF TIME CHOSEN IN TRACT BETWEEN CAMPOS (well over a BASE OF ADDRESS OR RELEASED OR ISSUED BY THE MESSAGE OF SIGNALING) TO OTHER FIELDS BY DRIVERS LINK THEM TO THE ELECT DEVICES IN THEM AS THAT MAKE THE ESTABLISHMENT OF TIME TO DATA MESSAGES AND VOICE AMONG THE FIELDS AND THE VIAS between courses. FROM BEING USED SOLELY CONTROL AND SEPARATELY, THE EXPECTED INDEPENDENDIA SYSTEM OF CONTINUING OPERATIONS OTHER SYSTEM IN THE EVENT OF ERROR IN A PARTICULAR DEVICE OR UNIFORM an entire field. Synchronization signals AND CUTTERS ARE GENERATED BY ELECTED OR DEVICES CONTROLLERS PROVIDING SIGNALING LINK AND COUNTING AND TIMING MANAGERS SO THE CONNECTIONS BETWEEN FIELDS MAY BE SYNCHRONIZED THROUGHOUT THE SYSTEM. ELASTICOS reservoirs MAY BE USED TO FACILITATE A particular device each field or in the field, OPERATE asynchronously while providing data messages and voice signals PCM FORMAT THAT CAN BE TRANSMITTED BY SMART entire system.
