   STATUS      current
   DESCRIPTION
      "Identifies a transceiver as being either xTU-C or xTU-R.
       A VDSL2/ADSL/ADSL2 or ADSL2+ line consists of two
       transceivers: an xTU-C and an xTU-R.
       In the case of ADSL/ADSL2 and ADSL2+, those two transceivers are
       also called atuc and atur.
       In the case of VDSL2, those two transceivers are also called
       vtuc and vtur.

       Specified as an INTEGER, the two values are:
        xtuc(1)  -- central office transceiver
        xtur(2)  -- remote site transceiver"
   SYNTAX      INTEGER {

Xdsl2Direction ::= TEXTUAL-CONVENTION
     STATUS current
     DESCRIPTION
        "Identifies the direction of a band in a VDSL2/ADSL/ADSL2/
         ADSL2+ link.
         The upstream direction is a transmission from the remote end
         (xTU-R) towards the central office end (xTU-C).  The downstream
         direction is a transmission from the xTU-C towards the xTU-R.
         Specified as an INTEGER, the values are defined as
         follows:"
     SYNTAX INTEGER {
        upstream(1),   -- Transmission from the xTU-R to the xTU-C.
        downstream(2)  -- Transmission from the xTU-C to the xTU-R.
            }

Xdsl2Band ::= TEXTUAL-CONVENTION
     STATUS current
     DESCRIPTION
        "Identifies a band in a VDSL2/ADSL/ADSL2/ADSL2+ link.
         For a band in the upstream direction, transmission is from the
         remote end (xTU-R) towards the central office end (xTU-C).
         For a band in the downstream direction, transmission is from
         the xTU-C towards the xTU-R.
         For ADSL, ADSL2 and ADSL2+, which use a single band in the
         upstream direction and a single band
         in the downstream direction,
         the only relevant values are upstream(1) and downstream(2).
         For VDSL2, which uses multiple bands in each transmission
         direction, a band in the upstream direction is indicated by any
         of us0(3), us1(5), us2(7), us3(9), or us4(11), and a band in
         the downstream direction is indicated by any of ds1(4),
         ds2(6), ds3(8), or ds4(10).
         For VDSL2, the values upstream(1) and downstream(2) may be used
         when there is a need to refer to the whole upstream or
         downstream traffic (e.g., report the average signal-to-noise
         ratio on any transmission direction).
         Specified as an INTEGER, the values are defined as
         follows:"
     SYNTAX INTEGER {
        upstream(1),   -- Transmission from the xTU-R to the xTU-C

                       -- (refers to the single upstream band for

                       -- (refers to the single downstream band
                       -- for ADSL/ADSL2/ADSL2+ or to the whole
