     As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, BD-E1-IP adopts the innovative TDM over IP technology, time division multiplexing, it transports the legacy E1/T1 data through the existing Ethernet or IP network.
    BD-E1-IP is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of  E1/T1 over Ethernet or IP network. The uplink ports is  IEEE 802.3 compliant, 10/100BaseT auto-sensed Ethernet port.
   The Ethernet over E1 converter is a mini type device,which only half occupation of 19" device. It is very convenient for customer to use it.
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-E1-IP to provide legacy TDM services over wired or wireless packet network.

Typical Application:

   Application1: Point to Point Application

     two units E1 TDM over IP work with voice device (PBX,PCM) and ethernet device (switch or router),transmitting voice and ethernet data over ethernet network.

Application2: Point to Point Application

E1 TDM over IP work with Voice over E1 converter,transmitting voice and ethernet data over ethernet network.

Application3: Point to multipoint Application
                16units E1 TDM over IP work with 16E1 TDM over IP or E1/4E1/8E1 TDM over IP work with 16E1 TDM over IP.

Question1: Can Baudcom's E1 TDM over IP support SATOP (RFC4553) protocol?
Answer: Yes, our E1 TDM over IP can support SATOP (RFC4553) protocol.

Question2: Can Baudcom's E1 TDMoIP support CESoPSN (RFC5086) protocol?
Answer: CESoPSN is for framed E1, our BD-E1-IP can not suuport the protocol. Our BD-FE1-IP TDM over IP device can support the framed E1 protocol.

Question3: You have models T1 over Ethernet? I am currently using the brand's devices orion telecom 2T1/E1 over Ethernet, but this device has no point to multipoint application.
Answer: Our E1 TDM over IP (E1 over Ethernet) can support E1 or T1. Our device can support point to multi-point application. For example, one unit 16E1 device can work with 8 units 2E1 device.

Question4: Can your E1 over Ethernet converter work in 110V AC?
Answer: Our E1 TDM over IP device can support power supply AC 220V or AC 110V or DC 48V. We will provide you the device with AC 110V power supply.

Question5: Can Baudcom provide 1*RJ45 to 2*BNC male cable 50cm
Answer: Yes, Baudcom can provide the cable, but need to pay attention to line sequence.
