Brief Introduction
    As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, BD-2E1-IP-mini adopts the innovative TDM over IP technology, it transports the legacy E1 data through the existing Ethernet or IP network.
   The 2 E1 over ethernet converter can support E1 or T1 protocol,can used as E1 over ethernet converter or T1 over ethernet converter.
    BD-2E1-IP is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of E1 over Ethernet or IP network. The uplink ports are IEEE 802.3 compliant, 10/100BaseT 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.
    Telecom and Enterprise users can save a lot of access and equipement 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 BD-2E1-IP to provide legacy TDM services over wired or wireless packet network.
