30 Channel Voice over Ethernet (IP) Converter

The converter encapsulates the voice data in the IP packet, supports the UDP packet mode, and realizes the 1-30 voice service to the 100M Ethernet conversion, in the same network segment or through the router to achieve different network segment communication.

● High transmit efficiency, low transmit delay;

● Provide Console(CLI)/WEB management interface, easy to install and open;

●Voice port to support FXO/FXS/2-4 Wire E&M/2-4 wire Audio/Magnet phone interface, FXO port plug into PBX, FXS port is connected to the user’s telephone;

● Voice FXO/FXS interface, support for caller ID/reverse polarity billing/fax function;

● Both sides of the device support FXO+FXS hybrid access;

● Ethernet interface rate of 10/100M, full duplex/half duplex adaptive;

● Support power failure or automatic network recovery;

● Support Ethernet packet out-of-order recovery and cache to anti-network delay;

● Adjustable frame length to balance bandwidth and transmission delay;

● DC-48V/DC24V power supply with polarity automatic detection function; installation does not need to distinguish between positive and negative.
