4 E1 TDM over IP Ethernet Multiplexer
As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, BD-4E1-IP adopts the innovative TDM over IP technology, it transports the legacy E1/T1 data through the existing Ethernet or IP network.BD-4E1-IP is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of four E1/T1 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/T1 services. One particular application is to build E1/T1 links with low cost Wireless LAN bridges,replacing much more costly microwave radios. Operators can use BD-4E1-IP to provide legacy TDM services over wired or wireless packet network. Features1. User-friendly Web server supported for easy setup and maintenance2. Point to point and point to multipoint supported3. Four E1/T1 Ports supported, E1 or T1 easy selected by Web Manager4. Uplink ports 1+1 backup supported5. Stable E1/T1 clock recovery, low jitter and wander6. Low processing delay for E1/T1 channels, high bandwidth usage efficiency7. Resist to packet loss, with PCM frame synchronization protection8. User definable encapsulation packet size for different application9. Enough jitter buffer to resist packet delay variation (PDV)10. Local Ethernet port throughput limiting, assuring E1/T1 QoS11. Local and remote E1/T1 LOS and AIS and packet loss indication for trouble-shooting and maintenance. 12. Support IETF RFC4553 SAToP protocol, Ethernet encapsulation support IP/UDP 13. E1 clock supports 3 mode: local clock, adaptive and loopback 14. 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). 15. Ethernet support IEEE 802.3x, RSTP (802.1w), LLDP, CDP, Ethernet ring protection, OAM and MAC address automatic learning 16.

Application2: Point to multipoint Application,E1/4E1/8E1 TDM over IP work with 16E1 TDM over IP. Order information Product Model Descriptions BD-4E1-IP 4E1 TDM over IP, two 10/100M uplink ethernet(1+1), two downlink data ports, E1 120ohm, web management, double power AC220V+ DC48V Q&A Question 1: Can the 4E1 of Baudcom’s TDM over IP device be used as four separate E1to transmit different business? For example, an E1 for ethernet data transmission,one E1 for voice transmission and other E1 for video image transmission. Answer: Yes,Baudcom’s 4E1 TDM over IP can transmitt different business for every E1. The data in every E1 will be transparently transmitted.
