384Voice+4GE Fiber Mux

The series equipment is the company developed the PCM optical fiber transmission for the large-scale integrated circuit on the base of the developed of optical fiber transmission Provide 384 * voice，4 * 10/100/1000M fast Ethernet （wire speed 1000M），2*expansion interface(RS232/RS485/RS422 asynchronous data、switch signal） Ethernet interface can exchange for each other, and VLAN division The working is reliable, stable, and low power consumption, high integration, small size, easy for installation and maintenance.

● Based on self-copyright IC

● The equipment for 4U 19 inch a total of the optical port plates with 16 function boards.

● Maximum configured to 384*Voice, if you want to configure SNMP Network management need to remove a 24* Voice board, Configuring 1*N E1 board needs to remove a 24 * call board too.

● 384Channel voice access, supports caller ID feature and reverse polarity billing functions

● Support FXO/FXS, EM2/4 audio, Magnet Telephone Interface, FXO port docking with program-controlled switchboard, FXS port connected to the user’s telephone

● Support various sites’ mutual number allocation function

● 4Channel Ethernet interface is switch interface, supports VLAN

● Ethernet interface rate is 10/100/1000M, duplex/half duplex adaptive

● Can command the remote interface loop back to maintain the circuit

● The transmission distance is up to 2-120Km without interruption

● AC 220V, DC-48V, DC24V can be optional

● DC-48V/DC24V power has a polarity automatic detection function, you can install the device without differentiation between positive and negative polarity.

● Telephone interface with lightning protection, lightning reached IEC61000-4-5 Short circuit current wave 8 / 20μs, open-peak output voltage 6KV standards.
