More details

16 E1 T1 TDM over IP,E1 over ethernet:TOIP-16


Product Overview:


As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, TOIP-16 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 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.


TOIP-16 could work together with other members in TOIP family such as TOIP-8, TOIP-4, TOIP-2, TOIP-1 etc. to run legacy E1 services. 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 TOIP to provide legacy TDM services over wired or wireless Ethernet/IP network.
