MODEM "Clear To Send" missing
STAP TYP 00:00:00 NAME
MODEM "Clear To Send" missing
->MSGDEV (M.RDCS)
In Ring NAME the "Clear to send" signal is missing in the modem section of the SDLC
controller. We distinguish between two different types of Ring controllers:
FSK Here the cause may be a fault in the Ring controller's transmitter
section, or a short circuit at the controller's transmit output line.
V.24 Here the cause may be either that the modem is not providing the
signal, or that the jumper for connecting the signal to the Ring
Connection Unit is not in place. (V.24 Rings with version C are rare.)
Check and correctly set the jumper on the Ring Connection Unit (V.24). Otherwise,
replace the controller.
