4/8*Voice over Ethernet(IP)

Description

The Voice over Ethernet converter encapsulates the voice data in the IP packet, supports the UDP packet mode, realizes the 1-8 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 10M / 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;
• Based on hardware design, start fast;
• DC-48V / DC24V power supply with polarity automatic detection installation does not need to distinguish between positive and negative;
