2.2.33 Single CH 1:1 OLP Card (P1R1-M)
P1R1-M 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-M card provides the interface between the system and the network
management system; works with the network management system to
manage each card of the equipment and realizes the intercommunication
between the equipment.
P1R1-M 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-M card, there is an NM interface, a CONSOLE
interface, 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 2-40, LEDs are
described in Table 2-43.
