ENE-04 multiplexer

The ENE-04 multi-service multiplexer is designed for generating Е1 digital signals at a bit rate of 2.048 Mbit/s through multiplexing a wide range of analog and digital data signals. The ENE-04 is compatible with SDH equipment developed by EZAN/NEC and is supported by the Qport

 Main features:

• CTbus H.110 for switching 2048 timeslots, 64 Е1 tributaries; 
• Capable of housing up to 17 channel modules per crate; 
• Distributed control, power supply and cross-connect functions; 
• Hot swapping of similar modules; 
• Management and monitoring using the Qport network management system based on the SNMP protocol; 
• Can be mounted in a 19”and 21” rack; 
• Modern hardware components

Composition:

• Crate with a CTBus Н.110; 
• System controller module;
• Group and channel modules;
• Power supply module.

Supported network topologies:

Control:

• Local control via the F interface (RS-232) using a terminal control program;
• Local and remote control via the Q interface (Ethernet) using the QPort network management system based on the SNMP protocol.

Redundancy:
