The elastic buffer is placed in the receive path.
The elastic buffer is placed in the transmit path.
The elastic buffer is disabled.
The elastic buffer is enabled.
Remote loop is switched off.
Remote loop is switched on. The remote loop-back mode
disconnects the transmit data received on XDIP/N from the
transmitter. Received data on pins RL1/2 is looped back to the
line interface with or without jitter attenuation. The decoder and
encoder are ignored.
If LIM0.ARL (automatic remote loop) is selected and no valid
ARL condition is decoded, the remote loop stays active until RL
is reset (higher priority of RL compared to ARL)
Local loop is switched off.
Local loop is switched on. Data received on ports XDIP/N is
looped back through the analog receiver to pins RDOP/N. An
alarm indication signal (blue signal) can be sent to the remote
end (LIM1.XAIS). Data received on ports RL1/2 is ignored.
Receiver and transmitter coding must be identical.
Digital loop-back disabled.
Digital loop-back enabled. Data received on ports XDIP/N is
looped back to pins RDOP/N. Optinally an alarm indication
signal (blue signal) can be sent to the remote end (LIM1.XAIS).
