The channel ID 0.0 and 1.0 use the same Downconverter in the fallow frequency:
RF Interface : 2150 to 2162Mhz
IF Frecuency : 14 - 26Mhz
I have a problem because I buy the new downconverter with the fallow specification:
RF Interface: 2150 to 2162Mhz
IF Frecuency: 30-42Mhz
The transceivers that use for connect to CMTS use the fallow specification
RF Interface : 2150 to 2162Mhz
IF Frecuency : 14 - 26Mhz
The company where I buy the new downconverte they tell me that I need:
re-configure your CMTS box to receive customer modem signal at 30 to 42 MHz range while requesting from customer modem to transmit at 14 to 26 MHz range.
My Question for all is: żIt is possible this, the cable modem can transmit in diferent frequency?
I wait your commentaries

Hey there wiyat
In the UK, generally Cisco equipment is used for CMTS deployment rather than Arris on cable networks, although I believe Arris kit is being tested for the Docsis 3 trial (just a rumour though).
Cisco equipment is preferred due to its scalability and ease of administration through the Cisco Admin panel to change these types of settings. With Arris I'm not to sure what admin control is used, I'm only sued to Cisco myself.
Best bet is maybe to get in touch with the manufacturer direct.
Surely if you are using a CMTS kit, this would mean you work with an ISP, do you not have direct support for this equipment from the vendor ??
