GTD-3 EAX (Toll switch, NOT CCS7 capable although CCIS capable) GTD-5 EAX (Class 5 switch, many in use today, was the primary switch in former GTE exchanges. Now supported by Lucent.) GTD-120 Digital PABX; GTD-1000 Digital PABX; GTD-4600 Digital PABX; OMNI-S1 Digital PABX; OMNI-S2 Digital PABX; OMNI-S3 Digital PABX
A time switch (also called a timer switch, or simply timer) is a device that operates an electric switch controlled by a timer. Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall lights, stokers, and oil and gas burners." A consumer version was added in 1952.
A digital delay generator (also known as digital-to-time converter) is a piece of electronic test equipment that provides precise delays for triggering, syncing, delaying, and gating events. These generators are used in many experiments, controls, and processes where electronic timing of a single event or multiple events to a standard timing ...
The GTD-5 EAX (General Telephone Digital Number 5 Electronic Automatic Exchange) is the Class 5 telephone switch developed by GTE Automatic Electric Laboratories. This digital central office telephone circuit switching system is used in the former GTE service areas and by many smaller telecommunications service providers .
The Switching Network consists of four space division stages of 16x16 switches, and a time division section with 16 stages of 4x4 switches. Control is provided by the Coordination Processor. The Coordination Processors exists in several types: CP103 with max 22,000 BHCA (Busy Hour Call Attempts) CP112 with max 60,000 BHCA
In a time-slot interchange (TSI) switch, two memory accesses are required for each connection (one to read and one to store). Let T be the time to access the memory. Therefore, for a connection, 2T time will be taken to access the memory. If there are n connections and t is the operation time for n lines, then t=2nT which gives n=t/2T
Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn.
Digital clocks typically use the 50 or 60 hertz oscillation of AC power or a 32,768 hertz crystal oscillator as in a quartz clock to keep time. Most digital clocks display the hour of the day in 24-hour format; in the United States and a few other countries, a commonly used hour sequence option is 12-hour format (with some indication of AM or PM).
