SONET Compliance Codes
The SONET compliance code bits allow the host to determine with which specifications
a SONET transceiver complies. For each bit rate defined in Table 8 (OC-3, OC-12, OC-48),
SONET specifies short reach (SR), intermediate reach (IR), and long reach (LR) requirements.
For each of the three bit rates, a single short reach (SR) specification is defined. Two variations
of intermediate reach (IR-1, IR-2) and three variations of long reach (LR-1, LR-2, and LR-3) are
also defined for each bit rate.
