Product Overview:

As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, BD-16E1-IP adopts the innovative TDM over IP technology, with IP circuit emulation that supports transportation of 16 E1 over FE port. The uplink ports and user data ports are IEEE 802.3 compliant, 10/100 auto-sensed Ethernet ports.


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.


The 16E1 TDM over IP converter provide 2 power supply, 16 E1,2FE uplink 2FE downlink and one optical FE SFP slot.


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.

Application story:


Question1: Can the 16E1 TDM over IP device web management support different browsers?
Answer: Yes, the devices can be monitored and configured in most browers, for example, IE, Google Chrome, Firefox, etc.

Question2: Can the 16E1 TDMoIP converter support CESOP protocol?
Answer: The TDM over IP can not support CESOP protocol. Our BD-FE1-IP can support the CESOP protocol.

Question3: Thanks for your soon feedback and professional support. The only problem I see is, I don't need 220V AC. I would prefer 110/120V AC. Plus the option for -48V DC.
Answer: Our 16 E1 over Ethernet Multiplexer power is with a wide range, which can support AC 220V and 110/120V. The 16E1 TDMoIP device also can support double AC and DC 48V.

Question4: 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.

Question5: Can the 16 E1 TDMoIP converter support optical uplink? 

Answer: Yes, the E1 tdm over IP converter can support both 10/100M-TX electrical and 10/100M-FX optical uplinks.

Question6: Does the 16E1 ethernet converter support VLAN? 

Answer: Yes, the E1 tdm over ethernet converter can support VLAN function. The user can configure the VLAN and Q-in-Q VLAN via web management.
