Spot on - my upstream is channel 2 at 25.8 Mhz, TDMA

I'll see if I can find the 29.2Mhz one. Hopefully they will move to ATDMA and 18 Mb/s before too long, since the upgrade work seems to be in progress given I noticed the move from QPSK to 16QAM on DOCSIS 1. The DOCSIS 1 network here seemed to have three upstreams. Do you know if the upstream upgrade work provides more upstream channels as well as increasing the capacity of those already available? Where more than one is available what determines which one the modem will lock onto?

Also in a given area on DOCSIS 3 are the same 4 downstreams used by all or are there a pool of channels available and the modem will select 4 of them?
