Cisco ONS 15600 Reference Manual, R7.2
Chapter 12 Performance Monitoring
12.5.2 Physical Layer Parameters
12.5.2 Physical Layer Parameters
The ONS 15600 retrieves the OPR, OPT, and LBC from the line card and stores these values with the
PM counts for the 15-minute and 1-day periods. You can retrieve current OPR, OPT, and LBC values
for each port by displaying the card view in CTC and clicking the Maintenance > Transceiver tabs.
The physical layer performance parameters consist of normalized and non-normalized values of LBC,
OPT, and OPR. Table 12-4 defines the non-normalized values.
12.6 ASAP Card Performance Monitoring
The following sections define performance monitoring parameters for the Any Service Any Port (ASAP)
card.
12.6.1 ASAP Card Optical Performance Monitoring Parameters
Table 12-5 lists the near-end and far-end section layer PMs.

OC-192/STM64 Cards
Parameter Definition
Non-normalized LBC (mA)
1
1. This value should be somewhat consistent from port to port and cannot be configured.
The actual operating value of laser bias current (mA) for the specified
card port.
Non-normalized OPR (dbm)
2
2. This value will vary from port to port because of received optical signal power differences. This value can be configured by
calibrating the nominal value to the initial receive power level when the port is put in service.
The actual operating value of optical power received (dBm) for the
specified card port.
Non-normalized OPT (dbm)
1
The actual operating value of optical power transmitted (dBm) for the
specified card port.
