This displays the number of blocks received that
required correction due to corruption, but were unable to
be connected.
This displays the ID number of each channel on which
the downstream signal is transmitted.
Click this to return the Forward Error Connection (FEC)
columns (Correcteds and Uncorrectables).
This displays the index number of the OFDM receiver
(see OFDM on page 25).
This displays the type of Fast Fourier Transform in use
on the relevant OFDM receiver (see
Each OFDM signal consists of multiple subcarriers.This
displays the frequency, in Hertz, of the first OFDM
subcarrier on the relevant receiver.
This displays whether or not the relevant OFDM
connection's physical link channel (PLC) data is locked.
The PLC tells the E31N2V1 how to decode the OFDM
signal, and what power level to use. Once the E31N2V1
receives a PLC without uncorrectable errors, the PLC is
locked and subsequent communication can continue.
This displays whether or not the relevant OFDM
connection's next codeword pointer (NCP) data is
locked. The NCP tells the E31N2V1 which codewords
are to be used for OFDM communication, and which
profile to use for each codeword. Once the E31N2V1
receives an NCP without uncorrectable errors, the NCP
is locked and subsequent communication can continue.
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 E31N2V1 receives an MDC1
without errors, the MDC1 is locked and subsequent
communication can continue.
This displays the power level the E31N2V1 has been
instructed to use on the relevant OFDM connection by
the physical link channel (PLC) data, in dBmV (decibels
above/below 1 millivolt).
FFT on page 25).
