As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, BD-FE1-IP adopts the innovative TDM over IP technology, it transports the legacy E1 data through the existing Ethernet or IP network.

BD-2FE1-IP is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of four E1 over Ethernet or IP network. The uplink ports and user data ports are IEEE 802.3 compliant, 10/100M BaseT auto-sensed Ethernet port.

The state-of-the-art design provides the highest availability with the accurate timing signal and data bit stream reconstruction. Predefined system parameter profiles that according to different application requirement; ultimately simplify the installation process and saving the maintenance cost.

The E1 tdm over IP converter have the performance of high  transmission efficiency, low transmission delay, high precision clock recovery. Support 1E1 interface and IP internet transmission of 4 100MEthernet interface . It is also suitable for connecting to the wireless equipment to achieve fast deployment of E1 services. One particular application is to build E1  links with low cost Wireless LAN bridges, replacing much more costly microwave radios.
