INFORMATION

Overview:
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.

Features
1. User-friendly Web server supported for easy setup and maintenance
2. Point to point and point to multipoint supported
3. Four E1/T1 Ports supported, E1 or T1 easy selected by Web Manager
4. Uplink ports 1+1 backup supported
5. Stable E1/T1 clock recovery, low jitter and wander
6. Low processing delay for E1/T1 channels, high bandwidth usage efficiency
7. Resist to packet loss, with PCM frame synchronization protection
8. User definable encapsulation packet size for different application
9. Enough jitter buffer to resist packet delay variation (PDV)
10. Local Ethernet port throughput limiting, assuring E1/T1 QoS
11. 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 based8021.1P basedMAC 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.  Support POE (maximum power: 60W) (optional);

Typical Application
   Application1: Point to Point Application,two units 4E1 TDM over IP work with voice device (PBX,PCM) and ethernet device (switch or router),realizing voice and ethernet data over ethernet network.










Application2: Point to multipoint Application,E1/4E1/8E1 TDM over IP work with 16E1 TDM over IP.

General questions:

Question 1: Can  the 4E1 of Baudcom's TDM over IP device be used as four separate E1 to 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.
