Unreferenced date October 2009 A telecommunication circuit is any line, conductor, or other conduit by which information is Transmission telecommunications transmitted . A dedicated circuit , private circuit , or leased line is a line that is dedicated to only one use. Originally, this was analog signal analog , and was often used by radio station s as a studio transmitter link STL or remote pickup unit RPU for their sound reproduction audio , sometimes as a backup to other means. Later lines were digital , and used for private corporation corporate data network s. The opposite of a dedicated circuit is a switched circuit , which can be connected to different paths. A Plain old telephone service POTS or ISDN telephone line is a switched circuit, because it can connect to any other telephone number . On digital lines, a virtual circuit can be created to serve either purpose, while sharing a single physical circuit. Definitions A telecommunication circuit may be defined as follows The complete path between two terminals over which one way or two way communications may be provided. See communications protocol . An electronic path between two or more points, capable of providing a number of channel communications channels . A number of conductors connected for the purpose of carrying an Current electricity electric current . An electronic closed loop path among two or more points used for Signalling telecommunication signal transfer.

Telecommunication is a 1981 song by A Flock of Seagulls , from their first album. Although it did not chart on either the traditional United Kingdom UK or United States of America US charts, it received considerable time on the dance charts. Citation needed date May 2010 The up tempo beat featuring power chords and heavy synth, along with the futuristic lyrics, has enabled the song to reach cult following cult status. Citation needed date May 2010 The song is noteworthy because the band eschewed the guitar laden choruses many songs of this period had e.g. power ballad , and instead relied on percussion arpeggios and multi layered sounds. The effect is not unlike what is known as the wall of sound effect, although unlike recordings of Phil Spector who expressed interest in the band, calling them phenomenal ref Phil Spector out of his head .

In telecommunication , a drift is a comparatively long term change in an attribute, value, or operational parameter of a system or equipment. The drift should be characterized, such as diurnal frequency drift and output level drift. Drift is usually undesirable and unidirectional, but may be bidirectional, cyclic, or of such long term duration and low excursion rate as to be negligible. ref http www.its.bldrdoc.gov fs 1037 fs 1037c.htm Federal Standard 1037C ref Drift is also common in pseudo synchronised streaming applications, such as low latency audio streaming over TCP IP . Normally both ends of a streaming connection would stay in sync with a master clock but TCP IP does not provide this master clock mechanism. Therefore applications running fixed clocks will drift apart over time and glitch es will occur. This is usually fixed by controlling jitter or drift, by slightly altering the clock speed at one end of the connection. Drift can be removed from signals by signal combination. This strategy is used in optical and electrical systems such as optical tweezers . ref http rsi.aip.org resource 1 rsinak v82 i11 p115103 s1?isAuthorized no Mashaghi et al.

In telecommunication s, transparency can refer to The property of an entity that allows another entity to pass through it without altering either of the entities. The property that allows a transmission system or channel communications channel to accept, at its input, unmodified user information , and deliver corresponding user information at its output , unchanged in form or information content. The user information may be changed internally within the transmission system, but it is restored to its original form prior to the output without the involvement of the user. The quality of a data communications system or device that uses a bit oriented link protocol that does not depend on the bit sequence structure used by the data source. ref FS1037C MS188 ref ref DODDIC ref Some communication systems are not transparent. Non transparent communication systems have one or both of the following problems user data may be incorrectly interpreted as internal commands. For example, modems with a Time Independent Escape Sequence or 20th century Signaling System No. 5 and R2 signalling telephone systems, which occasionally incorrectly interpreted user data from a blue box phreaking blue box as commands. the output user data may not always be the same as the input user data.
