Correcteds This displays the number of blocks received that
required correction due to corruption, and were
corrected.
Uncorrectables This displays the number of blocks received that
required correction due to corruption, but were unable to
be connected.

OFDM Downstream Overview
Receiver This displays the index number of the OFDM receiver
(see OFDM on page 43).
FFT Type This displays the type of Fast Fourier Transform in use
on the relevant OFDM receiver (see FFT on page 43).
Subcarr 0 Frequency
(Hz)
Each OFDM signal consists of multiple subcarriers.This
displays the frequency, in Hertz, of the first OFDM
subcarrier on the relevant receiver.
PLC Locked This displays whether or not the relevant OFDM
connection’s physical link channel (PLC) data is locked.
The PLC tells the CODA-4x8x how to decode the OFDM
signal, and what power level to use. Once the CODA-
4x8x receives a PLC without uncorrectable errors, the
PLC is locked and subsequent communication can
continue.
NCP Locked This displays whether or not the relevant OFDM
connection’s next codeword pointer (NCP) data is
locked. The NCP tells the CODA-4x8x which codewords
are to be used for OFDM communication, and which
profile to use for each codeword. Once the CODA-4x8x
receives an NCP without uncorrectable errors, the NCP
is locked and subsequent communication can continue.
MDC1 Locked This displays whether or not the relevant OFDM
connection’s Multipath Delay Commutator (MDC) data
is locked. This provides information about the method of
Fast Fourier Transform (FFT) to be used on the OFDM
connection. Once the CODA-4x8x receives an MDC1
without errors, the MDC1 is locked and subsequent
communication can continue.
PLC Power (dBmV) This displays the power level the CODA-4x8x has been
instructed to use on the relevant OFDM connection by
the physical link channel (PLC) data, in dBmV (decibels
above/below 1 millivolt).
