Red
UNI-side optical signal receiving
indication:
On: the received optical power is lower
than threshold
Off: the received optical power is higher
than threshold
RI MASTER
Red
Optical signal receiving indication:
On: the optical power received by
MASTER channel is lower than threshold
Off: the optical power received by
MASTER channel is higher than threshold
RI SLAVE
Red
Optical signal receiving indication:
On: the optical power received by SLAVE
channel is lower than threshold
Off: the optical power received by
SLAVE channel is higher than threshold
NOTE
TO1 interface is used to transmit optical signals to MASTE channel;
RI1 interface is used to receive optical signals from MASTE channel;
TO2 interface is used to transmit optical signals to SLAVE channel;
RI2 interface is used to receive optical signals from SLAVE channel;
When the MASTER channel is fault-free:
1.
PRI: The optical path with high-priority
RO interface (connecting to RX interface of UNI-side device) outputs optical
signal which received by RI1 interface of NNI-side MASTER channel to the RX
interface of UNI-side PRI channel.
