UNEQUIPPED GENERATION
The TEMx28 Mapper is capable of generating and sending an unequipped channel or unequipped supervisory
channel over either the A or B buses or both buses for channel n. An unequipped VT/TU format consists of:
An unequipped supervisory VT/TU format consists of:
The various states associated with an unequipped channel selection are shown in the table below. Where n is
equal to 1-28.
Note: Control bits ATnTPTV (bit 5, X+063H) and BTnTPTV (bit 5, X+0D3H) must be set to 0 when generating
unequipped or supervisory unequipped.
