Descriptions
RI MASTER
Red
NNI-side 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
NNI-side 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;
TI interface (connecting to TX interface of UNI-side device) inputs UNI-side TX
signal and transmits it to NNI-side TO1 and TO2 interfaces.
RO interface (connecting to RX interface of UNI-side device) outputs optical
signal received by NNI-side RI1 and RI2 interfaces to the UNI-side RX interface.
Management Ports
P1P1-M provides 1 NM port and 1 CONSOLE port as its network
management ports, marks and definitions are shown in Table 2-12.
