Overview:

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. Features1.       User-friendly Web server supported for easy setup and maintenance2.       Support IETF RFC4553 SAToP protocol, Ethernet encapsulation support IP/UDP3.       Point to point and point to multipoint application4.       Eight E1 Ports supported5.       Provide 4 FE electrical ports and 1 FE optical port, 2 uplink ports, 2 local data ports or monitoring ports, optical port can be used for uplink or local data.6.       Stable E1 clock recovery, low jitter and wander7.       Low processing delay for E1 channels, high bandwidth usage efficiency8.       Resist to packet loss, with PCM frame synchronization protection9.       User definable encapsulation packet size for different application10.    Support VLAN settings for E1 service and in band VLAN management.11.    E1 clock supports 3 mode: local clock, adaptive and loopback12.    Enough jitter buffer to resist packet delay variation (PDV)13.    Local Ethernet port throughput limiting, assuring E1 QoS14.    Local and remote E1 LOS and AIS and packet loss indication for trouble-shooting and maintenance15.    Ethernet built-in layer 2 switch, support VLAN(port based, 802.1Q based and QinQ based), QoS(port based,8021.1P based,MAC based and TOS based).
