i think its not limited by

i think its not limited by cable modem.. its limited on cmts. on bsr1000 docsis 1.1 its limited at 6000 classefires, you can put all classefiers on 1 cm.

classifiers in practical scenarios

Ok thanks, that's the theory

i change my question to : On heavy scenario, for heavy user , how many classifier are activated on the average for a CM?
Im sure its a lot less than 6000.
can i say the a CM can't activate more then 32 classifiers at the same time and still work great on heavy scenario?

yes, i think 32 is the

yes, i think 32 is the maximum number of class on cm.

what's added with docsis 3.0

in regards to modem tlv's for docsis 3.0. what's added:
docsis version: value 3 added as legal value

upstream freq band now has support for up to 85Mhz

upstream symbal rate, indicates whether the modem is able to support various upstream symbol rates, required to only support the 5120, 2560 and 1280 ksps rates.

selectable active code mode 2. indicates that modem supports selecting codes with a bit string when number of active codes is less than 128

code hoping mode 2. indicates the modem supports hopping of only active codes in matrix

5.12 Msps upstream transmit channels. # channels

2.56 Msps upstream transmit channels. # channels

total SID clusters. total number of SID groupings

SID clusters per service flow. number of SID clusters ( = # SID's supported on any 1 channel on any flow
