Object

column r/w SNMPv2-TCDisplayString 
A Directory Number. Directory Numbers are used
to identify incoming calls on the signaling
channel given in isdnDirectorySigIndex.
              
The format of this information largely depends on the type
of switch or PBX the device is connected to. Therefore,
the detailed format of this information is not
specified and is implementation dependent.
              
If possible, the agent should implement this information
using the E.164 number format. In this case, the number
must start with '+'. Otherwise, IA5 number digits must
be used.

Syntax

Base type

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.
