CRC—Cyclical redundancy check (CRC) word size. The CRC is an error-checking technique that
uses a calculated numeric value to detect errors in transmitted data.
Encapsulation—Indicates whether HDLC or PPP encapsulation is used on the interface.
Framing—Framing for optical digital transmission. SONET is the North American standard, SDH
is the European standard.
Payload Scrambling—Indicates whether or not SONET payload scrambling is enabled on the
interface. Payload scrambling ensures that there is sufficient bit-transition density to maintain the
transmit clock for synchronous signalling. Both ends of the connection must use the same
scrambling algorithm.
Transmit Clock Source—Source of the transmit clock.
loopTiming—Indicates that the recovered receive clock is used as the transmit clock.
–
localTiming—Indicates that the transmit clock source is generated internally.
