A transcoding of the form ADPCM-PCM-ADPCM (adaptive differential pulse code modulation-pulse code modulation-adaptive differential pulse code modulation) when there are no transmission errors and the integrity of the bit stream is preserved. [T1.310-1991]

A multiplexing scheme in which timing is obtained from a clock that controls both the multiplexer and the channel source.

The term "Synchronous Test Line" denotes an arrangement in an end office which performs marginal operational tests of supervisory and ring-tripping functions.

In a Broadband Integrated Services Digital Network (B-ISDN), a proposed transport level technique in which time-division multiplexing and switching is to be used across the user's network interface.

Digital transmission in which the time interval between any two similar significant instants in the overall bit stream is always an integral number of unit intervals.
Note: "Isochronous" and "anisochronous" are characteristics, while "synchronous" and "asynchronous" pertain to relationships.

The basic logical building block signal of synchronous optical networks (SONET). The STS-1 signal has a bit rate of

The process of setting the frequency of one oscillator equal to that of another.
Note: The term "synchronization" is commonly used in place of "syntonization" to mean the same thing. [T
