Frame sync (FSYNC), Serial Clock (SCK), Serial audio data (SDATA), Channel
status (C), User channel data (U), and data validity information (VERF) are
passed directly to the transmitter section for reformatting into the output data
stream. VERF is an OR’ing of the validity information from the incoming data (V)
with an internal error flag (ERF) that detects serious transmission errors such as
parity errors, bi-phase coding violations and an out-of-lock PLL receiver. Errors
are displayed on the front panel to aid in troubleshooting. VERF then becomes
the transmitted validity bit (V) and can be used by downstream error correction
devices to interpolate through errors.
FRONT PANEL DISPLAYS AND SWITCHES
