Section 4 says:

UNITS definition of the following MIB objects, should change from dBm to dB.
That will also fix the conflict with the units appearing in the Description of these MIB objects (dB).

vdslPhysCurrSnrMgn
vdslPhysCurrAtn
vdslLineConfDownMaxSnrMgn
vdslLineConfDownMinSnrMgn
vdslLineConfDownTargetSnrMgn
vdslLineConfUpMaxSnrMgn
vdslLineConfUpMinSnrMgn
vdslLineConfUpTargetSnrMgn

Example of original text:
   vdslPhysCurrSnrMgn OBJECT-TYPE
       SYNTAX       Integer32 (-127..127)
       UNITS        "0.25dBm"
       MAX-ACCESS   read-only
       STATUS       current
       DESCRIPTION
           "Noise Margin as seen by this Vtu with respect to its
           received signal in 0.25dB.  The effective range is
           -31.75 to +31.75 dB."
       REFERENCE    "T1E1.4/2000-009R3, Part 1, common spec"
        ::= { vdslPhysEntry 5 }

It should say:

Notes:

This Errata replaces errata 1788 (rejected because it did not include list of all MIB objects having this problem and could not be edited).
It was decided by the adslmib Forum, that the solution should be as described by this Errata.
