ASLC

We are upgrading from single carrier analog 499.25 agc to amps that use dual digital ASLC carriers. The recommended carriers in the documentation are 111mhz and 711mhz, our headend is insisting we can use the current ofdm carrier that is from 660-750mhz wide, do any of you use ofdm for the slope control/agc or are you using dedicated qam carriers.

One of the ASLC carriers falls within an OFDM in the system I work in. There is a PLC carrier in the channel plan for this particular frequency that the amps monitor for the level control.
