asynchronous
ON
– Async operation
OFF
– Sync operation
Sync
Section 2

1STB
Section 6
Controls the RTS to DCD
transfer
transfer
ON
– DCD, the DCD signal
turns on when the two units
reach synchronization
OFF
reach synchronization
OFF
– CNT, the DCD signal of
the local unit follows the RTS
signal of the remote unit
DCD
Note: The DCD signal is OFF when a digital loopback is active (receiving RLB command) or when there is no
synchronization between the units).
