Object
column SNMPv2-TCDisplayString
Channels are numbered 1.1.1, 2.1.1, 3.1.1, 1.2.1, ....
The digits are called K, L and M: K.L.M
SDH/E1
======
Refer to G.707 7.3
K = TUG3 number
L = TUG2 number
M = TU-1 number
MLK
ITU-T defines a linear numbering where the K-part is always
changed between two subsequent numbers. Refer to G.707 Figure 7-27:
K L M
1 = 1.1.1
2 = 2.1.1
3 = 3.1.1
4 = 1.2.1
5 = 2.2.1
We call this MLK/ITU-T numbering
The objects are normally listed in MLK-order in the XTM Series.
KLM
There is another numbering called KLM where K is most significant
and M is changed between two subsequent numbers
K L M
1 = 1.1.1
2 = 1.1.2
3 = 1.1.3
4 = 1.2.1
5 = 1.2.2
SONET/T1
========
K = STS-1-SPE
L = VTG
M = VT1.5

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.
