High Quality Content by WIKIPEDIA articles! In telecommunication, a D-4 is a framing standard for traditional time-division multiplexing, which standard describes user channels multiplexed onto a trunk that has been segmented (framed) into 24 bytes of 8 bits each. Note: The multiplexing function is performed in the D-4 framing structure by interleaving bits of consecutive bytes as they are presented from individual circuits into each D-4 frame. Within Telecommunications operations, a D4 Bank also refers to a type of multiplexer which mux's 24 DS0 signals into a single DS1.
