The EDMAC overhead channel may also be used to convey M&C data to a RF Transceiver at the
distant end of a satellite link if it is connected to a CDM-600, or to a BUC or LNB at the distant end
of a satellite link if it is connected to a CDM-600L.
For the CDM-600L, this FSK interface with the BUC includes a BUC output power leveling mode,
whereby the modem M&C monitors the detected BUC output power level reported on the FSK link
and automatically adjusts the modem Tx output power to maintain a constant BUC Tx output level.
See Appendix E. ODU (CSAT-5060, KST-2000A/B) OPERATION VIA THE CDM-600 or
Appendix F. ODU (BUC/LNB) OPERATION VIA THE CDM-600L for further information.
