As a cost effectivesolution for the traditional telecom services migrate to the IP packetnetworking technology, BH-TDM Series adopts the innovative TDM over IP technology, with IP circuit emulation that supports transportation of 1 /2 /4 /8 /16 E1/T1 over FE port.The uplink ports and user data ports are IEEE 802.3 compliant, 10/100auto-sensed Ethernet ports.

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

Telecom and Enterprise users can save a lot of access and equipment costs and generates new revenue by offering different types of service over existing Ethernet networks. 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.Operators can use BH-TDM Series to provide legacy TDM services over wired or wireless packet network.
