communications link. When it blinks it’s a logic type error
(synchronization, wrong framing…) and when it remains on
it’s a physical type error (short-circuit, open circuit, low
signal…).

interface with a range of 2000 meters (if your installation
entails a range greater than 2000 meters, contact our sales
department).
RJ48 type connector: twisted pair cable interface with
software configurable impedance: 120 / 75 ohms for E1 and
