2 Channel E1 Protection Switch
Model
FCCE-E2
Description :
This series of equipment is an E1 switcher developed on the basis of special VLSI developed by our company. Two independent E1 switching protection functions are provided.
Overview
Features
● Integrated circuits based on independent intellectual property rights;
● Built in relay, when device power off, support transmission on mainE1line;
● When LOS, AIS, LOF and CRC4 alarms occur on the current transmitting E1 line, the system will switch to another E1 line without damage;
● When the E1 line is in the PCM framing mode, it can be switched according to the CRC4 error;
● You can choose to configure the standby E1 line not to send HDB3 code when the main E1 lineworks;
● Avariety of power supply options: AC220V, DC-48V/DC24V, etc;
● DC-48V/DC24V power supply with automatic polarity detection, no need to distinguish positive and negative when installing.
