6.  xDSL Multi-Pair Bonding MIB Definitions

   The GBOND-MIB module IMPORTS objects from SNMPv2-SMI [RFC2578],
   SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], SNMP-FRAMEWORK-MIB
   [RFC3411], IF-MIB [RFC2863], and HC-PerfHist-TC-MIB [RFC3705].
   The module has been structured as recommended by [RFC4181].

    DESCRIPTION
      "The objects in this MIB module are used to manage the
      multi-pair bonded xDSL interfaces, as defined in ITU-T
      Recommendations G.998.1, G.998.2, and G.998.3.

      This MIB module MUST be used in conjunction with a bonding
      scheme-specific MIB module, that is, G9981-MIB, G9982-MIB,
      or G9983-MIB.

       This notification MAY be sent for the -O subtype ports
       while the port is 'up', on the crossing event in both
       directions: from normal (rate is above the threshold) to low
       (rate equals the threshold or is below it) and from low to
       normal.  This notification is not applicable to the -R

       It is RECOMMENDED that a small debouncing period of 2.5 sec,
       between the detection of the condition and notification,
       be implemented to prevent simultaneous LinkUp/LinkDown and
       gBondLowUpRateCrossing notifications from being sent.

       The adaptive nature of the G.Bond technology allows the port
       to adapt itself to the changes in the copper environment;
       e.g., an impulse noise, alien crosstalk, or a
       micro-interruption may temporarily drop one or more BCEs in
       the aggregation group, causing a rate degradation of the
       aggregated G.Bond link.  The dropped BCEs would then try to
       re-initialize, possibly at a lower rate than before, adjusting
       the rate to provide the required target SNR margin.

       Generation of this notification is controlled by the
       gBondPortConfLowRateCrossingEnable object.

       rates, modified to compensate for fragmentation and
       encapsulation overhead (e.g., for an Ethernet service, the
       target data rate of 10 Mbps SHALL allow lossless transmission
       of full-duplex 10-Mbps Ethernet frame stream with minimal
       inter-frame gap).
       Note that the target upstream data rate may not be achieved
       during initialization (e.g., due to unavailability of required
       BCEs) or the initial bandwidth could deteriorate, so that the
       actual upstream data rate (gBondPortStatUpDataRate) could be less
       than gBondPortConfTargetUpDataRate.

       The value is limited above by 10 Gbps, to accommodate very
       high speed bonded xDSL interfaces (e.g., 32 x 100 Mbps).

       The value between 1 and 10000000 indicates that the total
       upstream data rate of the G.Bond port after initialization
       SHALL be equal to the target data rate or less, if the target
       upstream data rate cannot be achieved under the restrictions
       configured for BCEs.  In cases where the copper environment
       allows a higher upstream data rate to be achieved than that
       specified by this object, the excess capability SHALL be
       either converted to an additional SNR margin or reclaimed by
       minimizing transmit power.

       The value of 0 means that the target data rate is not
       fixed and SHALL be set to the maximum attainable rate during
       initialization (best effort), under specified spectral
       restrictions and with a desired SNR margin per BCE.

       This object is read-write for the -O subtype G.Bond ports.
       It is irrelevant for the -R subtypes -- attempts to read or
