Zhone Technologies has unveiled ETHX 3100 series platforms with Pseudo-wire Edge-to-Edge Emulation (PWE3) enabling operators to migrate TDM applications onto a converged packet network for simpler network management and OPEX savings.
The 3100 series Ethernet Access Devices (EADs) provide enhanced Virtual LAN support with Quality of Service (QoS) for sensitive voice and video services, making it suitable for 3G/4G mobile backhaul and T1/E1 leased line applications. The new platform with PWE preserves existing PBX and TDM equipment investments and is cost optimised to provide operators fast return on investment, the company claims.
Zhone said that the new platform enables up to 48Mbps over four copper pairs and supports IP, MPLS and MEF encapsulation. The ETHX 3100s support a variety of clock recovery techniques and comply with the clock accuracy requirements defined by the ITU-T G.8261 specification.
The company has also introduced the ETHX-3140, a four port EAD without pseudowire emulation for pure IP environments. The ETHX-3100 and 3140 can be configured and managed via Zhone’s ZMS, or a simple web interface for point and click configuration.

Steven Glapa, VP of product marketing and management for Zhone, said: “Our 3100 series gives operators a very quick win by eliminating the cost of high-end T1 or E1 lines without sacrificing quality. In the US alone, out of a quarter-million existing cell towers, more than 200,000 are still copper fed making the opportunity even more immediate for operators as the rapid rise in cellular traffic demands higher-bandwidth backhaul.”
