PE> Which section would that be in?  Presumably not the bit that says:

PE> 29:30 Trellis encoder select bits:
PE> 0 = 16 state, 1 = 32 state, 2 = 64 state, 3 = reserved for ITU
PE> Receiver REQUIRES remote-end transmitter
PE> to use selected trellis encoder.

RS> Again, you are reading to much into the specific wording
RS> there on the question of all three being mandated.

PE> NOTE - Source modem does not use bits 29-32, and should set these bits to 0

PE> So Rod, just where does the transmitter get to select
PE> maximum supported trellis-encoding, when it is SPECIFICALLY
PE> REQUIRED to zero out the bits that deal with trellis coding?

PE> So try explaining how the calling modem says that it supports a maximum
PE> of 16S trellis coding, when it has to zero-out all the bits.  Have fun.

No need to, clearly it manages to do that somehow when the rockwell
datapump doesnt support 64S. The most likely explanation for how it
achieves that is that you have focused on just one bit of the V34
protocol involved in that negotiation and missed the other bit that
is used to achieve that outcome. Wouldnt be the first time, they aint
easy to read, particularly the hardware ones.

RS> Now try explaining how the rockwell chipsets which
RS> dont have 64S actually manage to work Paul. Have fun.

PE> What evidence do you have that the Rockwell does
PE> not acknowledge the called USR's request for 64S?

64S isnt used dorko.
