  2. Tone remote - Wikipedia

    en.wikipedia.org/wiki/Tone_remote

    For example, a dispatch center for taxicabs may have an office downtown but have a base station on a distant mountain top. A Tone remote , also known as an EIA Tone remote , is a signaling system used to operate a two-way radio base station by some form of remote control.

  3. Two-wire circuit - Wikipedia

    en.wikipedia.org/wiki/Two-wire_circuit

    A modern line card has no two-to-four wire conversion whatsoever; it is strictly an analog/digital interface to a system that has a completely digital and integrated signal path internally. Using actual wires to circuit switch a telephone call became obsolete when the crossbar switch (a mechanical system) was replaced by 4ESS electronic ...

    en.wikipedia.org/wiki/SAE_J1708

    The standard defines a 2-wire 18 gauge wire cable that can run up to 130 feet (40 m) and operates at 9600 bit/s. A message is composed of up to 21 characters, unless the engine is stopped and the vehicle is not moving in which case transmitters are allowed to exceed the 21 byte max message length.

    Later that year, 2Wire published the Open Gateway Management Protocol (OGMP). [2] The OGMP formed the basis for the TR-069 WAN management protocol subsequently ratified by the DSL Forum in 2004. In early 2003, 2Wire delivered a wireless gateway with a complete system-on-a-chip architecture. Also in 2003, the company acquired Sugar Media, a ...

    A SP1 2-wire variant was also available that provided Centrex services. A version of the SP-1 ESS that could provide both 2 & 4 wire services was also built. The first instance was installed in Vegreville Alberta in 1976 or 1977. SP1 4-Wire (Toll) The first example of this switch was installed for Bell Canada, in Thunder Bay, Ontario in late 1973.

    A common example is to run the entire calculation suite for different input frequencies, and then plot samples on a single chart. One might use this to sample through the UHF television frequencies, for instance, producing a diagram that illustrates the gain across the band. Another common feature is an iterative solver that adjusts a given ...

  8. Balanced line - Wikipedia

    en.wikipedia.org/wiki/Balanced_line

    A signal transmitted over a balanced line. The signal is kept intact while the noise (which appears as a common-mode signal at the receiving end) is rejected perfectly.. In telecommunications and professional audio, a balanced line or balanced signal pair is an electrical circuit consisting of two conductors of the same type, both of which have equal impedances along their lengths, to ground ...

    For example, C1 is the first capacitor, L1 is the first inductor, Q1 is the first transistor, and R1 is the first resistor. Often the value or type designation of the component is given on the diagram beside the part, but detailed specifications would go on the parts list.
