2BASE-TL Connectors and LEDs

The HN4000 connects to the outside voice‐grade copper plant through two 2BASE‐TL
50‐pin RJ‐21 ("Champ") connectors (Figure

The HN4000 has one status LED for each 2BASE‐TL pair. Table 3‐5 describes the LEDs'
operation.

LED State Description
Off The numbered port has no copper pair attached. Or, if there is a copper pair
attached, the numbered port and the associated port at the CP have not yet
started to train.
Steady Green The copper pair attached to the numbered port has trained with the associated
port at the CP, but there is not traffic passing on the port.
Blinking Green Blinking at approximately 2 blinks/second indicates that the port is in the process
(Slow) of training. The duration of the training process is dependent on the length of the
copper loop connecting the ports.
Blinking Green Blinks as traffic passes through the port, after the pair is trained.
