held in the burst position. For the A/B mode
the burst position causes a single signaling
sequence to be output. For the DPL and
DPL lnv modes the Burst position causes a
133 Hz tone to be output. For the Tone
Remote mode either the Burst or the Cont
position causes a tone remote access
sequence to be output. The access sequence
leaves tone A at a low level for transmit-type
commands until the switch is returned to the
Off position. This switch is spring loaded to
return to the Off position from the Burst
position.
