This table is deprecated in favour of using
ifStackTable.
The table was mandatory for systems dividing a DS1
into channels containing different data streams
that are of local interest. Systems which are
indifferent to data content, such as CSUs, need
not implement it.
The DS1 fractional table identifies which DS1
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 an application managing a
North American ISDN Primary Rate link whose
division is a 384 kbit/s H1 _B_ Channel for Video,
a second H1 for data to a primary routing peer,
and 12 64 kbit/s H0 _B_ Channels. Consider that
some subset of the H0 channels are used for voice
and the remainder are available for dynamic data
calls.
We count a total of 14 interfaces multiplexed onto
the DS1 interface. Six DS1 channels (for the sake
of the example, channels 1..6) are used for Video,
six more (7..11 and 13) are used for data, and the
remaining 12 are are in channels 12 and 14..24.
Let us further imagine that ifIndex 2 is of type
DS1 and refers to the DS1 interface, and that the
interfaces layered onto it are numbered 3..16.
We might describe the allocation of channels, in
the dsx1FracTable, as follows:
dsx1FracIfIndex.2. 1 = 3 dsx1FracIfIndex.2.13 = 4
dsx1FracIfIndex.2. 2 = 3 dsx1FracIfIndex.2.14 = 6
dsx1FracIfIndex.2. 3 = 3 dsx1FracIfIndex.2.15 = 7
dsx1FracIfIndex.2. 4 = 3 dsx1FracIfIndex.2.16 = 8
dsx1FracIfIndex.2. 5 = 3 dsx1FracIfIndex.2.17 = 9
dsx1FracIfIndex.2. 6 = 3 dsx1FracIfIndex.2.18 = 10
dsx1FracIfIndex.2. 7 = 4 dsx1FracIfIndex.2.19 = 11
dsx1FracIfIndex.2. 8 = 4 dsx1FracIfIndex.2.20 = 12
dsx1FracIfIndex.2. 9 = 4 dsx1FracIfIndex.2.21 = 13
dsx1FracIfIndex.2.10 = 4 dsx1FracIfIndex.2.22 = 14
dsx1FracIfIndex.2.11 = 4 dsx1FracIfIndex.2.23 = 15
dsx1FracIfIndex.2.12 = 5 dsx1FracIfIndex.2.24 = 16
For North American (DS1) interfaces, there are 24
legal channels, numbered 1 through 24.
For G.704 interfaces, there are 31 legal channels,
numbered 1 through 31. The channels (1..31)
correspond directly to the equivalently numbered
time-slots.
