RFC 1407 MIB 33
dsx3FracTable {1.3.6.1.2.1.10.18.13} Implementation of this group is optional. It is designed for
those systems dividing a DS3/E3 into channels containing different data streams
that are of local interest. The DS3/E3 fractional table identifies which DS3/E3
channels associated with a CSU are being used to support a logical interface, i.e.,
an entry in the interfaces table from the Internet-standard MIB.
For example, consider a DS3 device with four high-speed links carrying router
traffic, a feed for voice, a feed for video, and a synchronous channel for a
non-routed protocol. The allocation of channels, in the dsx3FracTable, is described
as follows.
dsx3FracIfIndex.2. 1 = 3 dsx3FracIfIndex.2.15 = 4
dsx3FracIfIndex.2. 2 = 3 dsx3FracIfIndex.2.16 = 6
dsx3FracIfIndex.2. 3 = 3 dsx3FracIfIndex.2.17 = 6
dsx3FracIfIndex.2. 4 = 3 dsx3FracIfIndex.2.18 = 6
dsx3FracIfIndex.2. 5 = 3 dsx3FracIfIndex.2.19 = 6
dsx3FracIfIndex.2. 6 = 3 dsx3FracIfIndex.2.20 = 6
dsx3FracIfIndex.2. 7 = 4 dsx3FracIfIndex.2.21 = 6
dsx3FracIfIndex.2. 8 = 4 dsx3FracIfIndex.2.22 = 6
dsx3FracIfIndex.2. 9 = 4 dsx3FracIfIndex.2.23 = 6
dsx3FracIfIndex.2.10 = 4 dsx3FracIfIndex.2.24 = 6
dsx3FracIfIndex.2.11 = 4 dsx3FracIfIndex.2.25 = 6
dsx3FracIfIndex.2.12 = 5 dsx3FracIfIndex.2.26 = 6
dsx3FracIfIndex.2.13 = 5 dsx3FracIfIndex.2.27 = 6
dsx3FracIfIndex.2.14 = 5 dsx3FracIfIndex.2.28 = 6
There are 28 legal channels, numbered 1 through 28 for dsx3M23,
dsx3SYNTRAN, dsx3CbitParity, and dsx3ClearChannel.
For e3Framed there are 16 legal channels, numbered 1 through 16. The channels
(1…16) correspond directly to the equivalently numbered timeslots.
Object Name Object ID User Access Object Description Get Set
dsx3FracIndex dsx3FracEntry 1 read-only The index value which uniquely identifies the
DS3 interface to which this entry is applicable.
The interface identified by a particular value of
this index is the same interface as identified by
the same value an dsx3LineIndex object
instance. (2) - Returns
the ifIndex of
the DS3
interface.
dsx3FracNumber dsx3FracEntry 2 read-only The channel number for this entry. Returns 0.
dsx3FracIfIndex dsx3FracEntry 3 read-write An index value that uniquely identifies an
interface. The interface identified by a
particular value of this index is the same
interface as identified by the same value an
ifIndex object instance. If no interface is
currently using a channel, the value should be
zero. If a single interface occupies more than
one time slot, that ifIndex value will be found
in multiple time slots. Returns 0. Can assign
the channel to
an interface.
