the received optical signals. The OSC interface uses LC dual-fiber SFP
module or single-fiber SFP module.
On the front panel of P1R1-P card, there are two OSC optical interfaces
and six LEDs. The PRI channel and SEC channel on the UNI side
respectively provide an RO interface and a TI interface; NNI side CHL1
channel provides a TO1 interface and an RI1 interface; CHL2 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.
