WebCable modem channels are displayed as “downstream channels number x upstream channels number.”. For example, 8×4, 24×8 or 32×8. The downstream is always listed first. The upstream is always listed second. For example, 8×4 means that your cable modem has four (4) download channels and eight (8) upload channels. The higher the numbers ...
