cdm570RxDemodType
Module: CDM-570
OID (symbolic): CDM-570::cdm570RxDemodType
OID (numeric): 1.3.6.1.4.1.6247.24.1.2.3.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Rx demodulation type, where: 0 = BPSK 1 = QPSK 2 = OQPSK 3 = 8-PSK 4 = 16-QAM (Turbo or Viterbi + RS only) 5 = 8-QAM
Depending on FEC type, not all of these selections will be valid.
What is cdm570RxDemodType?
This read-write object sets the receive demodulation type to one of BPSK(0), QPSK(1), OQPSK(2), 8-PSK(3), 16-QAM(4) (Turbo or Viterbi+RS only), or 8-QAM(5). As with cdd564RxDemodulation, this must exactly match the modulation the far-end transmitter is using, and because 16-QAM specifically requires either Turbo or Viterbi+Reed-Solomon coding per the MIB's own note, selecting it without the matching FEC type configured would be an invalid, non-functional combination. A hub operator upgrading their outbound carrier from QPSK to 16-QAM to increase throughput must ensure every remote's Rx demodulation type is updated to demod16QAM(4), and its FEC type confirmed compatible, before those remotes can reacquire lock on the changed carrier.
