至于传统的电信业务成本有效的解决方案，迁移到IP分组的网络技术，BD-8E1-IP采用创新的TDM over IP技术，它输送遗留E1数据通过现有的以太网或IP网络。

BD-8E1-IP是新一代基于IP的TDM设备与IP电路仿真，支持八个E1和以太网或IP网络中的两个本地网口的交通。 上行链路端口和用户数据的端口都符合IEEE 802.3，个10 / 100BaseT自动感应以太网端口。

国家的最先进的设计，提供了最高的可用性与准确的定时信号和数据比特流重构。 根据不同的应用的要求，即预定义的系统参数型材; 最终简化安装过程，节省了维护成本。

电信和企业用户可以节省大量的接入和设备成本，并通过在现有的以太网网络提供不同类型的服务产生新的收入。 它也适合于连接到无线设备实现快速部署的E1业务。 一个特定的应用是构建低成本无线局域网网桥E1链路，更换更昂贵的微波无线电。 运营商可以利用BD-8E1-IP超过有线或无线分组网络提供传统的TDM服务。

As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, BD-8E1-IP adopts the innovative TDM over IP technology, it transports the legacy E1 data through the existing Ethernet or IP network.

BD-8E1-IP is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of eight E1 and two local Ethernet ports over Ethernet or IP network. The uplink ports and user data 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 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 BD-8E1-IP to provide legacy TDM services over wired or wireless packet network.
