4. Firmware Description
Auto and manual data speed selector description:
4-Band VDSL CO modem is a 4 band VDSL solution which supports real plug & play and can do auto and manual selection of the
data speed, the setting of the data speed depends on the phone cable limit, they can support 5M/15M/25M
symmetrical data service
but depends on installation environment. If 4-Band VDSL CO modem try to link at the data speed of 25Mbps but fails to do so, then
4-Band VDSL CO modem data speed must be lower due to the limitation of the phone cable length. If the cable length is unsure,
then auto selection of the data speed at the default setting is recommended. Power must be unplug before changing of data speed,
then power on and wait for VDSL to link again at the correct data speed function.

We recommend that phone cable must meet CAT 3 standard or above and without clustering,
otherwise the above
guarantee will be void.
