High transmission efficiency, minimal transmission delay, and high precision clock recovery are all features of the 4 E1 TDM over IP. 1E1 interface and IP internet transmission of 4 100MEthernet interfaces are supported.

The revolutionary TDM over IP technology used by the equipment transmits legacy E1 data over an existing Ethernet or IP network. With accurate timing signal and data bit stream reconstruction, the state-of-the-art design ensures the maximum availability. Predefined system parameter profiles that may be customized to meet the needs of various applications, simplifying the installation procedure and lowering maintenance costs.

It is a new generation of TDM over IP equipment that includes IP circuit emulation and can transport four E1s across an Ethernet or IP network. IEEE 802.3 compliant uplink and user data ports, as well as a 10/100M BaseT auto-sensed Ethernet port.
