If it works fine on an unused downstream and upstream port, then wouldnt the angle that its sharing traffic with others be a reason why 38 Mbps cant be achieved on production link? Theres also all the timing/contention issues involved in a product link, too.

Yes, I´ve tested this on an unused downstream and upstrean port in the head end and the download speed is achieved without problem. Apparently there are no factors to unable to pass 20Mb of download on some of the optical... Someone has a similar problem?

Hello, Does anyone know what the best things to do when you have speed problems with cable modems in different downstream/upstream? This is the scenario: uBR 10K with about 17000 customers. Each downstream is configured with 256qam and all upstream have 16qam of modulation. In some cases the upstreams have a load-balance configuration with 2 or 3 upstream per optical node. There are no problems of SNR and FEC. All values are regular... And the used bandwidth are low.. After that, in some upstream can not go to the 20Mb of download Bandwidth and with the configuration used, should arrive without problem to 37Mb... I tested several cable modems and the problem still remain ... Someone has suggestions or ways of action to overcome this type of problem?
