4E1 TDM over Ethernet (IP) Converter | Desktop Type

View : 795
Type : E1 TDM over Ethernet (IP)
Description :

This 4E1 TDM over Ethernet (IP) converter is mainly used to transmit E1 signals on the IP network. The TDM over Ethernet converter allows people to seamlessly and reliably connect TDM equipment.


The 4E1 TDM over Ethernet (IP) converter is mainly used to transmit E1 signals on the IP network. It enables operators and enterprises to seamlessly and reliably connect TDM equipment and user Ethernet on a standard low-cost wireless or wired Ethernet/IP structure without any impact on quality.


The 4E1 TDM over Ethernet converter is transparent to TDM signals and ensures the seamless connection of any equipment with a physical E1 interface, such as PBX, mobile base station, SS7 signaling equipment, and voice mail system. TDM over Ethernet converter can be used in IP-based communication systems, such as LAN, WAN, MAN, and wireless networks.


The 4E1 TDM over Ethernet converter has 4 E1 service ports, 2 10/100/1000M Ethernet ports, a 100/1000M adaptive SFP optical port, and one console management interface.
