1 x E1 over Ethernet multiplexer product is a new generation of TDM over IP technology with IP circuit emulation that supports transportation of 1 E1 over an Ethernet or an IP network.

The uplink Ethernet port and user data port are IEEE 802.3 compliant, 10 / 100BaseT auto-sensed ports. The state-of-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 simplifies the installation process and saving maintenance cost.

Telecom and Enterprise users can save significant access and equipment costs and generate new revenue resources by offering different types of legacy services over Ethernet networks. It is also suitable for connecting to the Ethernet based wireless equipment to achieve fast  deployment of E1 services. One particular application is to provide a combination of Ethernet and E1 services using low cost Wireless LAN bridges, or over RPR Ethernet rings. Operators can use the 1 x E1 over Ethernet multiplexer to provide a provide a combination of Ethernet and legacy E1 (TDM) services over wired or wireless packet networks, or RPR rings.

TDM technology occupies fixed transmission bandwidth which is suitable for real-time applications such as voice and video. Ethernet technology is based on statistical multiplexing, transmitting and exchanging information in packets. It does not take up a fixed transmission bandwidth, which is good for achieving higher bandwidth utilization. But Ethernet technology does not provide adequate QoS for real time applications.

The 1 x E1 over Ethernet can be used to emulate transparent E1channels over an Ethernet link with an acceptable QoS (Please see the note: QOS, below), so that a majority of the existing E1 based applications can be readily setup over Ethernet LANs and WANs.
