Overview:
As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology(time division multiplexing), BD-4E1-IP E1 over Ethernet Multiplexer 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.
- SupportIETF RFC4553 SAToP protocol, Ethernet encapsulation support IP/UDP
- E1 clock supports 3 mode: local clock, adaptive and loopback
- 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).
- Ethernet support IEEE 802.3x, RSTP (802.1w), LLDP, CDP, Ethernet ring protection, OAM and MAC address automatic learning
- Support POE (maximum power: 60W) (optional);

Question1: Can the 4E1 of Baudcom’s TDM over IP device can be used as four seperate E1 to transmit different business? For example, a E1 for Ethernet data transmission, one E1 for voice transmission and other for video image transmission.
Answer: Yes, Baudcom’s 4E1 TDM over IP can transmit different business for every E1. The data in every E1 will be transparently transmitted.
Question2: 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.
Specification
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.

a) How can I exclude timeslot 0 from being sent and expected to be received by your device?
Answer: No.Cannot exclude timeslot 1 from being sent.
b) In case there is no way to exclude timeslot 0 what data does your device expect to receive?
Answer: The E1 data included the timeslot 0 which is International Standards, we cannot exclude the timeslot 0, if without timeslot, that cannot work.
Your device connect to our device by E1 port.
E1 has 32 timeslots, the 0th time slot is used to transmit the synchronization data, and the remaining 31 time slots can be used to transmit valid data. No timeslot 0, E1 data can not be identified. The E1 meet to G.703/704 standard protocol. Timeslot 0 is neccesary.
After our device received your E1 data, our device packed the E1 data into ethernet packet, make it can transmit in etherent network.
In the remote site, our E1 TDM over IP device get the ethernet packet, it will restore the ethernet packet to E1 data. Then transmit to your E1 device.
During the process, your data is restored to its original E1 data. Our device do not change your data.
