The Local DSX1 Channel LOOPBACK LED is on solid when it is
selected by the Select push-button. When the Local DSX1 Channel
LOOPBACK LED blinks at a fast rate, the T-1 CSU/DSU has the DSX1
(Customer T-1 interface) looped back onto itself (see circled loop in
Figure.) and was activated locally. When the Local DSX1 Channel
Loopback LED blinks at a slow rate the T-1 CSU/DSU has the DSX1
(Customer T-1 interface) looped back onto itself but was activated by
the carrier provider or the remote unit sending a V.54 command. When
this loopback is activated, data continues to be transmitted to the
customer equipment. The color of this LED is red.
