The device offers a Console and WEB management interface, facilitating installation and activation.

It features an Ethernet interface with a speed of 10M/100M, supporting full-duplex/half-duplex auto-negotiation.

It supports automatic recovery from power outages or network disconnections.

It supports Ethernet packet reordering and caching mechanisms to combat network latency.

The frame length can be adjusted to balance bandwidth and transmission latency.

Based on hardware design, the device offers fast startup speed.

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

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

The telephone interface supports mutual number allocation between both sites.

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