64 Channel Telephone POTS Line over Ethernet (IP) Extender

This converter encapsulates voice data into IP packets and supports UDP packetization. It enables the conversion of 64 voice services to 2*100 Mbps Ethernet. It can be used within the same subnet or achieve communication between different subnets through a router.

● The Ethernet interface supports speeds of 10 Mbps/100 Mbps and can operate in full-duplex or half-duplex mode with auto-negotiation.

● It supports automatic recovery in case of a power outage or network failure.

● The converter supports Ethernet packet reordering and caching to mitigate network delays.

● Users can adjust the frame length to balance bandwidth and transmission latency.

● Based on hardware design, it ensures fast startup.

● The voice ports support various interfaces such as FXO/FXS/2-wire audio/magnetic telephone interfaces. The FXO port connects to a PBX, while the FXS port connects to user telephones.

● For voice FXO/FXS access, it supports caller ID display, reverse polarity billing, and fax functionality.

● The telephone interface facilitates mutual dialing between two sites.

● The device supports management via Console serial port and web-based management.

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