Product Details
256 channel voice optical transmitter and receiver fiber optic network equipment.
Product Overview
The series equipment is the company developed the PCM optical fiber transmission for the large scale integrated circuit on base of the developed of optical fiber transmission Provide 256 channals call,4 way 10/100M fast Ethernet(line 100M),1 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 of installation and maintenance.
Features
- The equipment for 4U 19 inch a total of optical port plate with 16 function board.
- Maximum configured to call 256,if you want to configure SNMP Network management need to remove a 16 way call board configuring 1*N E1 board needing to remove a 16 way call board too.
- 256 Channel voice access, supports caller ID feature and reverse polarity billing functions
- Support various sites mutual number allocation function
- Voice port supports FXO and FXS port,, FXO port docking with program-controlled switchboard, FXS port connected to the user's telephone
- 4Channel Ethernet interface is switch interface, support VLAN
- Ethernet interface rate is 10/100M,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 polarity automatic detection function, you can install the device without differentiation between positive and negative polarity.
