Enumeration
The Forward Error Correction (FEC) interleaving used
for this downstream channel.
Values are defined as follows:
taps8Increment16(3): protection 5.9/4.1 usec,
latency .22/.15 msec
taps16Increment8(4): protection 12/8.2 usec,
latency .48/.33 msec
taps32Increment4(5): protection 24/16 usec,
latency .98/.68 msec
taps64Increment2(6): protection 47/33 usec,
latency 2/1.4 msec
taps128Increment1(7): protection 95/66 usec,
latency 4/2.8 msec
taps12increment17(8): protection 18/14 usec,
latency 0.43/0.32 msec
The value 'taps12increment17' is supported by EuroDOCSIS
cable systems only, and the others by DOCSIS cable systems.
If the interface is down, this object either returns
the configured value (CMTS), the most current value (CM),
or the value of unknown(1).
The value of other(2) is returned if the interleave
is known but not defined in the above list.
See the associated conformance object for write
conditions and limitations. See the reference for the FEC
configuration described by the setting of this object.
