   DESCRIPTION
      "This type defines a subset of downstream PSD mask
       breakpoints used to notch radio frequency interference (RFI)
       bands.
       Each RFI band is represented by 4 octets: a 16-bit start
       subcarrier index followed by a 16-bit stop subcarrier
       index.
       There is a maximum of 16 RFI bands allowed.
       The subcarrier index is an unsigned number in the range 0 to
       NSC-1."

       breakpoint.  The third octet holds the PSD reduction at the
       breakpoint from 0 (0 dBm/Hz) to 255 (-127.5 dBm/Hz) using units

   DESCRIPTION
        "
         This document defines a Management Information Base (MIB)
         module for use with network management protocols in the
         Internet community for the purpose of managing VDSL2, ADSL,
         ADSL2, and ADSL2+ lines.

         The MIB module described in RFC 2662 [RFC2662] defines
         objects used for managing Asymmetric Bit-Rate DSL (ADSL)

Top      Up      ToC       Page 58 
         interfaces per [T1E1.413], [G.992.1], and [G.992.2].
         These object descriptions are based upon the specifications
         for the ADSL Embedded Operations Channel (EOC) as defined
         in American National Standards Institute (ANSI) T1E1.413
         [T1E1.413] and International Telecommunication Union (ITU-T)
         G.992.1 [G.992.1] and G.992.2 [G.992.2].

         The MIB module described in RFC 4706 [RFC4706] defines
         objects used for managing ADSL2 interfaces per [G.992.3]
         and [G.992.4], and ADSL2+ interfaces per [G.992.5].  That MIB
         is also capable of managing ADSL interfaces per [T1E1.413],
         [G.992.1], and [G.992.2].

         This document does not obsolete RFC 2662 [RFC2662] or
         RFC 4706 [RFC4706], but rather provides a more comprehensive
         management model that manages VDSL2 interfaces per G.993.2
         [G.993.2] as well as ADSL, ADSL2, and ADSL2+ technologies
         per T1E1.413, G.992.1, G.992.2, G.992.3, G.992.4, and
         G.992.5
         ([T1E1.413], [G.992.1], [G.992.2], [G.992.3], [G.992.4], and
         [G.992.5], respectively).

         Additionally, the management framework for VDSL2 lines
         specified by the Digital Subscriber Line Forum
         (DSLF) has been taken into consideration [TR-129].  That
         framework is based on the ITU-T G.997.1 standard [G.997.1] and
         its amendment 1 [G.997.1-Am1].

         The MIB module is located in the MIB tree under MIB 2
         transmission, as discussed in the MIB-2 Integration (RFC 2863
         [RFC2863]) section of this document.

      "Request a bits-per-subcarrier measurement to be made.

       A request for a bits-per-subcarrier measurement is made by
       setting this object to the value of 'measure'.  Upon
       completion of the measurement request, the Access Node shall set
       this object to 'idle'.

       The SNMP agent should allow initiating a bits-per-subcarrier
       measurement process only if there is no other bits-per-subcarrier
       measurement already running, and respond with an SNMP error
       (e.g., wrongValue) otherwise.

       Note that a bits-per-subcarrier measurement is also performed
       during a line diagnostic procedure.  This object provides an
       additional mechanism to fetch the bits-per-subcarrier data.  This
       additional mechanism is provided so that bits-per-subcarrier
       data may be fetched without forcing the line into no power state.
       This is useful because the bits-per-subcarrier allocation may be
       adjusted at show time due to rate adaption and bit swapping.

       The implementation of this additional mechanism for measuring
       bits per subcarrier is not mandatory.

       The results of the bits-per-subcarrier measurement are stored in

Top      Up      ToC       Page 65 
       is made by modifying the xdsl2LineCmndConfBpsc object from

       The measurement results may be very large and will not fit
       into a single PDU; hence, multiple SNMP GET requests may be
       required to fetch the measurement results.
       Because the measurement results cannot be fetched atomically,
       it is possible for a second manager to start a new measurement
       before a first manager has fetched all of its results.
       An SNMP manager can use this object to ensure that the
       measurement results retrieved using one or more GET requests
       all belong to the measurement initiated by that manager.

       The following steps are suggested in order for the SNMP
       manager to initiate the bits-per-subcarrier measurement:

       1. Wait for xdsl2LineCmndConfBpsc value to be idle(1).
       2. Perform an SNMP GET for xdsl2LineCmndConfBpscRequests.
       3. Wait a short delay (4 -> 8 seconds).
       4. Perform an SNMP SET on xdsl2LineCmndConfBpsc with
          the value measure(2).
       5. If step 4 returns an error, then go to step 1.
       6. Wait for xdsl2LineCmndConfBpsc value to be idle(1).
       7. Fetch measurement results using one or more GET PDUs.
       8. Perform an SNMP GET for xdsl2LineCmndConfBpscRequests.
       9. Compute the difference between the two values of
          xdsl2LineCmndConfBpscRequests.  If the value is one,
          then the results are valid, else go to step 1."

   DESCRIPTION
      "Automode cold start forced.  This parameter is defined in

       automode when it is enabled in the MIB.
       Change the value of this parameter to 'true' to indicate a change
       in loop conditions applied to the devices under the test.  The
       xTUs shall reset any historical information used for automode
       and for shortening G.994.1 handshake and initialization.

       Automode is the case where multiple operation-modes are enabled
       through the xdsl2LConfProfXtuTransSysEna object in the line
       configuration profile being used for the line, and where the
       selection of the actual operation-mode depends not only on the
       common capabilities of both xTUs (as exchanged in G.994.1), but
