           "The transmit power spectral density mask code, used
           to avoid interference with HAM (Handheld Amateur Radio)
           radio bands by introducing power control (notching) in one
           or more of these bands.

           Amateur radio band notching is defined in the VDSL
           spectrum as follows:

           Band  Start Frequency     Stop Frequency
           ----  ------------------  --------------------------------
           30m   1810 kHz            2000 kHz
           40m   3500 kHz            3800 kHz (ETSI); 4000 kHz (ANSI)
           80m   7000 kHz            7100 kHz (ETSI); 7300 kHz (ANSI)

           Notching for each standard band can be enabled or disabled
           via the bit mask.

           are enabled via the bit mask, then the following objects
           MUST be specified:

           If customNotch1 is enabled, then both

5.  Security Considerations

   There are a number of management objects defined in this MIB module
   with a MAX-ACCESS clause of read-write and/or read-create.  Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.

   Some of the readable objects in this MIB module (i.e., objects with a
   MAX-ACCESS other than not-accessible) may be considered sensitive or
   vulnerable in some network environments.  It is thus important to
   control even GET and/or NOTIFY access to these objects and possibly
   to even encrypt the values of these objects when sending them over
   the network via SNMP.

   VDSL layer connectivity from the Vtur will permit the subscriber to
   manipulate both the VDSL link directly and the VDSL embedded
   operations channel (EOC) for their own loop.  For example, unchecked
   or unfiltered fluctuations initiated by the subscriber could generate
   sufficient notifications to potentially overwhelm either the
   management interface to the network or the element manager.

   Additionally, allowing write access to configuration data may allow
   an end-user to increase their service levels or affect other end-
   users in either a positive or negative manner.  For this reason, the
   following tables should be considered to contain sensitive
   information:

      - vdslLineTable
      - vdslLineConfProfileTable
      - vdslLineAlarmConfProfileTable

   Individual line utilization information, available via the
   performance tables, may be considered sensitive.  For example, if an
   end-user has a far lower line utilization during certain periods of
   the day, it may indicate an empty office or residence.  For these
   reasons, the following tables should be considered to contain
   sensitive information:

      - vdslPerfDataTable
      - vdslPerfIntervalTable
      - vdslPerf1DayIntervalTable

   Further, notifications generated by agents implementing this MIB will
   contain threshold and performance information.

Top      Up      ToC       Page 72 
   It is thus important to control even GET access to the objects within
   these tables and possibly to even encrypt the values of these objects
   when sending them over the network via SNMP.  Not all versions of
   SNMP provide features for such a secure environment.

   SNMP versions prior to SNMPv3 did not include adequate security.
   Even if the network itself is secure (for example by using IPSec),
   even then, there is no control as to who on the secure network is
   allowed to access and GET/SET (read/change/create/delete) the objects
   in this MIB module.

   It is RECOMMENDED that implementers consider the security features as
   provided by the SNMPv3 framework (see [RFC3410], section 8),
   including full support for the SNMPv3 cryptographic mechanisms (for
   authentication and privacy).

   Further, deployment of SNMP versions prior to SNMPv3 is NOT
   RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
   enable cryptographic security.  It is then a customer/operator
   responsibility to ensure that the SNMP entity giving access to an
   instance of this MIB module is properly configured to give access to
   the objects only to those principals (users) that have legitimate
   rights to indeed GET or SET (change/create/delete) them.
