Radiance T3/E3 Single Interface Line Cards 15
Remote Output Coaxial Link Loss
Loss of link to the remote device produces a red alarm condition at the remote
site and should force the device to revert to its internal clock. If the remote
device is configured to send back a yellow alarm (AIS) under this condition, the
two Radiance T3/E3 line cards will carry the alarm forward to the local device,
as shown below.
