As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, the 16 E1 over Ethernet (E1 over IP) adopts the innovative TDM over IP technology, with IP circuit emulation that supports transportation of 8~16 E1s and 5 GE electrical ports and 1 GE SFP optical port. The uplink ports and user data ports are IEEE 802.3 compliant, 10/100/1000M 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 device can support point to point applicaton (two units work in pairs, one device at each end of the network mode point to point). The device also can support point to multipoint application (the 16 E1 device work together with other members in Baudcom TDM over IP family such as 1E1/2E1/4E1/8E1 tdm over ip device). Telecom and Enterprise users can save a lot of access and equipment costs and generates new revenue by offering different types of services over their packet-switched infrastructure. 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 Baudcom TDM over IP devices to provide legacy TDM services over wired or wireless Ethernet/IP network.
