Medium Table

UP_ARROW138B.GIF (883 bytes)
SONET/SDH interfaces for some applications may be electrical interfaces and not optical interfaces. This group handles the configuration information for both optical SONET/SDH interfaces and electrical SONET/SDH interfaces.

Field Descriptions

sonetMediumType This variable identifies whether a SONET or a SDH signal is used across this interface.
sonetMediumTimeElapsed The number of seconds, including partial seconds, that have elapsed since the beginning of the current error-measurement period.
sonetMediumValidIntervals The number of previous intervals for which valid data has been stored.  A SONET device must support at least n intervals. The minimum value of n is 4. The default of n is 32. The maximum value of n is 96. The value of this object will be n unless the device was brought online within the last (nx15) minutes, in which case the value will be the number of complete 15 minute intervals the device has been online.
sonetMediumLineCoding This variable describes the line coding for this interface. The B3ZS and CMI are used for electrical SONET/SDH signals (STS-1 and STS-3). The Non-Return to Zero (NRZ) and the Return to Zero are used for optical SONET/SDH signals.
sonetMediumLineType This variable describes the line type for this interface. The line types are Short and Long Range Single Mode fiber or Multi-Mode fiber interfaces, and coax and UTP for electrical interfaces. The value sonetOther should be used when the Line Type is not one of the listed values.
sonetMediumCircuitIdentifier This variable contains the transmission vendor's circuit identifier, for the purpose of facilitating troubleshooting.
