nbsEusmCableTestResult – NBS-EUSM-MIB

Object

column SNMPv2-TCDisplayString

This string will give out the result of the cable test done
with a time stamp that gives the indication as to when the
CableTest was initiated. This also gives the result for all
the 4 pairs of wire. Possible results status includes
invalid, good, mismatch short and open.
              
When the status is mismatch, short or open, there will be
length indicating more information about the location of the
fault. From the LNXNM point of view it is easy to deal with
scalars than tables - so this is made into DisplayString.
Since the MVs use it read-only and display anyway, it is
probably simpler to deal with scalar display string rather
than table. An example TestResult may look like the
following
              
  <time-stamp>pair-1 good,pair-2 invalid,pair-3 open at 25
  meters,pair-4 good.

Syntax

SNMPv2-TCDisplayString

Source: SNMPv2-TCDisplayString
Base type: OctetString
Display format: 255a

Type Description

Represents textual information taken from the NVT ASCII
          
character set, as defined in pages 4, 10-11 of RFC 854.
          
To summarize RFC 854, the NVT ASCII repertoire specifies:
          
  - the use of character codes 0-127 (decimal)
          
  - the graphics characters (32-126) are interpreted as
    US ASCII
          
  - NUL, LF, CR, BEL, BS, HT, VT and FF have the special
    meanings specified in RFC 854
          
  - the other 25 codes have no standard interpretation
          
  - the sequence 'CR LF' means newline
          
  - the sequence 'CR NUL' means carriage-return
          
  - an 'LF' not preceded by a 'CR' means moving to the
    same column on the next line.
          
  - the sequence 'CR x' for any x other than LF or NUL is
    illegal.  (Note that this also means that a string may
    end with either 'CR LF' or 'CR NUL', but not with CR.)
          
Any object defined using this syntax may not exceed 255
characters in length.
