	Switching system for digital transmission network - Patent 4774703
		The HDB3 output 111 is connected to the input of the normal channel 1 and the HDB3 output 112 is connected to the first of seven HDB3 inputs 91 to 97 of the switching circuit 9 whose HDB3 output 98 is connected to the input of the emergency channel 8.
		The HDB3 outputs of the two output circuits 119 are connected to the HDB3 outputs 111 and 112 of the transmission junction 11.
		The HDB3 output of transcoder 219 is connected to the seven outputs 101 to 107 of the time shift compensation circuit 10, whose seven control inputs 81 to 87 are connected together and connected to the inputs controlling the variation of the delay of each of the variable incremental delay circuits 101.

	MV1442 - HDB3 Encoder/Decoder/Clock Regenerator (Obsolete) (Zarlink Semiconductor) (Site not responding. Last check: 2007-10-09)
		The MV1442 is an encoder/decoder for the HDB3 pseudo-ternary transmission code, described in Annex A of CCITT Recommendation G.703.
		Error monitoring functions are provided to detect violations of the HDB3 coding, all ones detection and loss of input (all zeros detection).
		The circuits are fabricated in CMOS and operate from a single +5V supply with all inputs and outputs being TTL compatible.

		If you have three partitions, hda3, hdb3, and hdc3, and each is about 2Gb, they will create a resultant linear volume of 6Gb.
		The first third of the linear volume will reside on hda3, the last third on hdc3, and the middle third on hdb3.
		Linear mode is also a good way to combine partitions of different sizes on different disks when you just need a single big partition (and don't really need to increase performance).

		The conventional way of recovering clock is to feed the recovered data stream (not the one which has been HDB3 decoded, but the combination "OR" of the positive and negative input data) and stick it into a low Q tuned circuit.
		Amplify the resulting sine wave and square off.
