    DESCRIPTION
       "This variable identifies whether a SONET
       or a SDH signal is used across this interface."
    ::= { sonetMediumEntry 1 }

sonetMediumTimeElapsed OBJECT-TYPE
    SYNTAX  Integer32 (1..900)
    MAX-ACCESS  read-only
    STATUS  current
    DESCRIPTION
       "The number of seconds, including partial seconds,
       that have elapsed since the beginning of the current
       measurement period. If, for some reason, such as an
       adjustment in the system's time-of-day clock, the
       current interval exceeds the maximum value, the
       agent will return the maximum value."
    ::= { sonetMediumEntry 2 }

sonetMediumValidIntervals OBJECT-TYPE
    SYNTAX  Integer32 (0..96)
    MAX-ACCESS  read-only
    STATUS  current
    DESCRIPTION
       "The number of previous 15-minute intervals
       for which data was collected.
       A SONET/SDH interface must be capable
       of supporting 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 will be <n> unless the measurement was
       (re-)started within the last (<n>*15) minutes, in which
       case the value will be the number of complete 15
       minute intervals for which the agent has at least
       some data. In certain cases (e.g., in the case
       where the agent is a proxy) it is possible that some
       intervals are unavailable.  In this case, this
       interval is the maximum interval number for
       which data is available. "

          sonetFacilityLoop
             The received signal at this interface is looped back
             out through the corresponding transmitter in the return
             direction.

          sonetTerminalLoop
             The signal that is about to be transmitted is connected
             to the associated incoming receiver.
