As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology, AN-TDM-IP-8E1 adopts the innovative TDM over IP technology, it transports the legacy E1 data through the existing IP network.

AN-TDM-IP-8E1 is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of eight E1 and two local Ethernet ports over the IP network. The uplink port and user data ports are IEEE 802.3 compliant, 10/100BaseT auto-sensed Ethernet ports.

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 requirements 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 services. One particular application is to build E1 links with low cost Wireless LAN bridges, replacing much more costly microwave radios. Operators can use AN-TDM-IP-8E1 to provide legacy TDM services over wired or wireless packet network.

The heart of AN-TDM-IP-8E1 is the TDM/Packet processing unit. It truncates E1/T1 data stream, putting the data into Ethernet packet with or without IP headers. The packets are passed to the Ethernet switch unit via MII interface, and are sent out adaptive the uplink ports. Ethernet data from two local data port are also sent out through the uplink ports, but with lower priority than those packets containing E1/T1 data.
