The system Multiplexer E3 -(EoPDH) provides:

• Multiplexing of 12 x E1 digital streamsE1 
• Мултиплексира 12 х Е1 цифрови потока и един поток с агрегатна скорост 8Mbit/s, в който е вкаран един 10BaseT LAN
• Digital streams can be plesiochronous (not synchronous)
• Converts into higher bit rate streams and after that transmits digital signal with a bit rate of 34 Mbit/s via copper or fiber optic cables
• Built-in BER measuring system, which evaluates the transmission quality during in-service operation
• Management system: local and remote
• Management interface: RS.232
• The control unit functions as network, and multiplex unit.

Accessories:

• Subrack Multiplexer E3
• Power Supply Unit -36 to -72V DC
• Converter Unit 230V AC /- 48V DC

Interfaces:

• Control Unit with one optical network and tributary  interfaces
