View : 1,685
Type : Voice Over IP
Description :

The voice over ip converter encapsulates the voice data in the IP packet, supports the UDP packet mode, and realizes the 1-8 voice service to the 100M Ethernet conversion.


This converter encapsulates voice data in IP packets and supports UDP packetization. It enables converting 8-channel voice services to 2-channel 100M Ethernet, allowing communication within the same subnet or across different subnets through a router.

This device provides a Console (RS232) management interface, facilitating installation and activation.

The Ethernet interface supports 10M/100M rates, with auto-negotiation for full-duplex/half-duplex.

It supports automatic recovery in case of power or network outages.

It supports Ethernet packet out-of-order recovery and cache to anti-network delay.

● The frame length can be adjusted to strike a balance between bandwidth and transmission delay.

Based on hardware design, it ensures fast startup.

The voice interface supports FXO/FXS/2-wire or 4-wire EM/2-wire or 4-wire audio/magnetic telephone interfaces. The FXO port interfaces with a PBX, while the FXS port connects to the user’s telephone device.

It supports caller ID display, reverse polarity billing, and fax functionality.

The telephone interface supports mutual dialing between two sites.

It supports management through both Console serial port and web management.

Multiple power supply options are available, including AC220V, DC-48V/DC24V. It supports dual power backup modes such as AC+DC, AC+AC, and DC+DC.
