1~8*E1 to 4*ETH (2M) Protocol Converter

SVP10B E1 to Eth protocol converter provides 1* E1 interface and 4* Ethernet interfaces, can comprehensively replace simple 10/100BaseT to single E1 network bridge. Apply to carriers providing large bandwidth private line access or government, police, enterprise, etc to construct MAN/WAN network, or used to existing narrow private network upgrade. It can also apply to Intellectual Transportation System, Highway Video Monitoring System, High Fidelity Video Conference System and Security Video Monitoring Signal Transmission. 

E1Loop-back Isolation: When there is E1 link loop-back, the device can automatically detect and isolate this loop-back E1, and give alarm instruction. The isolation can effectively avoid the whole link blocking caused by Broadcast Storm. After loop-back being straight, E1 can automatically return to service. It is a unique function, which can effectively avoid service break caused by careless loop-back E1 during the project and operation maintenance.

Strong Power Supply Adaptation: The device working voltage range is wide (not less than nominal voltage ±20%), adopting appropriate lighting protection, adapt to power supply in remote rural areas.

Interface Surge Protection: Both E1 and Ethernet RJ45 interface adopt advanced SPD device, can effectively reduce the rate of communication interface breaking caused by power supply fluctuation and lighting induction.

Network Management Function:  The device supports local/remote network management, local/remote terminal alarm function.

Embedded Mini Switch:  The device has 4 switching network interfaces, can interconnect and intercommunicate.
