Said switchgear comprises an energy feeder unit (EB), an energy output unit (AB), a contact unit (SB) and an energy transfer unit (TB).

Output means (430) are used to output the digital output block of which a selected part is derived from B1.

This, in combination with additional output registers, output buffers, and an output bank decoder creates a four-way set associative cache memory in a single memory device.

The systematic bits and th e parity bits are grouped in output blocks, each output block to be assigned to an address of a constellation scheme.

A loading block having inlet ports that match the inlets of the channels can be mated to the inlets of the channels, and an outlet block can be mated to the outlets of the channels.

For each output block, the transmitter (110) generates multiple bursts having a training sequence that is shared by these bursts.

As a result, the output block is a product of the validated input.

The collar inlet can be selectively placed in fluid communication with the block outlet by the auto changer device.

Where an output block of the conventional decoder (20) is indicated as being a valid codeword by the first block decoder (26), the bytes in this block are marked as being correct.
