2.2.32 Single CH 1:1 OLP Card (P1R1)
P1R1 is a 1:1 optical line protection card. It supports automatic
/forced/manual switching modes in case of service interruption caused by
fiber line deterioration or interruption.
P1R1 card is used to process 1-channel optical monitoring channel and
monitor the received optical signals. The OSC interface uses LC dual-fiber
SFP module or single-fiber SFP module.
On the front panel of P1R1 card, there is an OSC optical interface and six
LEDs. The PRI channel and SEC channel on the UNI side respectively
provide an RO interface and a TI interface; NNI side MASTE channel
provides a TO1 interface and an RI1 interface; SLAVE channel provides a
TO2 interface and an RI2 interface. The front panel diagram is shown in
Figure 2-38, LEDs are described in Table 2-41.
