Figure A2, Illustration of the Required Connection, between the MTIP/MRING and
TTIP/TRING pins, in order to permit “Transmit Drive Monitoring” via the DMO
Bit-field.
Bit D1 – DLOS (Digital Loss of Signal)
This “Read-Only” bit-field indicates whether or not the Digital LOS Detector is currently
declaring an LOS condition.
If this bit-field is set to “1” then the “Digital LOS Detector” is currently declaring an
LOS condition. Conversely, if this bit-field is set to “0”, then the Digital LOS Detector is
NOT currently declaring an LOS condition.
Bit D2 – ALOS (Analog Loss of Signal)
This “Read-Only” bit-field indicates whether or not the Analog LOS Detector is currently
declaring an LOS condition.
If this bit-field is set to “1” then the “Analog LOS Detector” is currently declaring an
LOS condition. Conversely, if this bit-field is set to “0”, then the Analog LOS Detector
is NOT currently declaring an LOS condition.
