		Extended chords are tertian chords (built from thirds) or triads with notes extended, or added, beyond the seventh, including all the thirds in between the seventh and the extended note.
		The extended Euclidean algorithm is a version of the Euclidean algorithm; its input are two integers a and b and the algorithm computes their greatest common divisor (gcd) as well as integers x and y such that ax + by = gcd(a, b).
		In telecommunication, an extended superframe is a T-carrier framing technique in which framing requiring less frequent synchronization than the original T-carrier superframe format is provided for D-4 formatting and for on-line, real-time testing of circuit capability and operating condition.

	ESF - Extended SuperFrame
		Extended Superframe: A DS1 framing format in which 24 DS0 times lots plus a coded framing bit are organized into a frame which is repeated 24 times to form a superframe.
		A TI framing format that utilized the 193rd bit as a framing bit, but with a superframe made up of 24 frames instead of 12 (as in a D4 format).
		(extended superframe format) A framing format that extends DS1 framing from 12 to 24 frames so that an 8-kbps F-bit pattern can be used for three separate functions: framing, cyclic redundancy check, and a data link.

		One might imagine that when installing a new T1 line, that the information regarding the line configuration supplied by the Telco is always correct, but quite frequently this is not the case.
		On modern T1 lines, the line encoding on T1’s and the Framing are pretty standard at B8Zs and ESF (Extended Superframe) respectively.
		So the default setting of 0 to 110 ft. is always good unless you have some extended cabling inside your own premises.

		SF/ESF and RBS SF (SuperFrame) and ESF (Extended SuperFrame) are two variations in framing.
		SF With SF, (also commonly referred to as D4 Framing or D3/D4 Framing, which is the same as D1D or D2 with the exception of DS0 channel sequence numbering) the sync bit (that one bit inserted in the 193rd position of every frame) is used only as a pattern to detect frame sync.
		A superframe consists of 12 frames, and the sync bit pattern for those 12 frames is 1000 1101 1100.
