Switch-selectable DTE/DCE
The Async Fiber Optic Mini
Modem features a switch-
selectable DTE/DCE option.
This allows operation as DTE,
for connection to another
DCE such as a multiplexor
port, eliminating the need for
a cross cable.
Continuous or switched
operation
The carrier can be strapped
for either continuous
operation or switched
operation, controlled by the
RTS signal, for transfer of a
control signal end-to-end.
