uBR7200, frequency question

Hello,

We have a problem selecting the frequency for downstream channels on uBR7200.

From our frequency plan, only free frequency range is 110-124 MHz.

Can we use that frequency to confirure downstream channel?

What problems we may have, during use of this frequency?

What is the reccomended frequency for cable technology downstream channel?

Thank you.

Re: uBR7200, frequency question

Looking over the following link it states:

"With the exception of the UBR-MC16E, all Cisco cable modem cards in a 6 MHz NTSC channel environment operate using the 5 to 42 MHz upstream and 54 to 860 MHz downstream frequency range. In addition, all Cisco cable modem cards, with the exception of the UBR-MC16E, transmit downstream IF signals to an IF-to-RF upconverter using a 44 MHz frequency. "
