Axerra Announces Pseudo-Wire Access Device for Mobile Backhaul

Axerra Networks announced the availability of its AXN10-8 Pseudo-Wire Access Device designed to meet mobile wireless operators' growing traffic requirements for backhaul of both voice and data services in packet-based radio access networks (RANs). It also enables cable MSOs and metro Ethernet service providers to deliver traditional T1/E1 voice and data services for business customers.



The AXN10-8, generally available in Q3 of this year, becomes an integral part of the Axerra Pseudo-Wire solution for mobile wireless backhaul. The AXN10-8 combines ATM with IMA, circuit emulation, Frame Relay/HDLC/PPP, and Ethernet Pseudo-Wires in a single access device to enable backhaul of any combination of 2G, 2.5G, and 3G traffic, including CDMA 2000 plus 1RTT plus 1xEV-DO and GSM plus GPRS plus UMTS. The AXN10-8 is optimally sized, furnishing up to eight T1/E1 interfaces for connections to equipment already installed at the BTS and NodeB cell site, each soft-configurable for the type of Pseudo-Wire service required. It also furnishes Ethernet Pseudo-Wire services and four Ethernet ports for connections to new generations of cell-site equipment, aggregating the full range of existing and projected services for backhaul over a unified, packet-optimized RAN.



The AXN10-8 includes new functionality for grooming and consolidation of CDMA, GSM, and UMTS traffic that reduces latency while also optimizing bandwidth utilization in the RAN. In addition, the AXN10-8 is equipped with new OAM features that provide enhanced network visibility and reliability for cell-site backhaul.



Axerra said the new AXN10-8 furthers its role in meeting the stringent clocking requirements of both 2G and 3G network implementations. Axerra provides a high-precision clock recovery (HPCR) mechanism that has already been tested and is being deployed by major operators around the globe.

Using
Pseudo-Wires for Mobile Wireless Backhaul over Carrier Ethernet
The
continued evolution of mobile wireless services is toward technologies
that are intrinsically packet-oriented, such as HSDPA and HSUPA, and
indicative that packet access networks, rather than TDM-based T1s and E1s,
are the logical transport for backhaul in the RAN. A number of new
technologies that are cost-effective and provide flexible, high-capacity
backhaul transport are emerging as the frontrunners for next-generation
packet access networks. These new technologies include Carrier Ethernet
(also known as Metro Ethernet or Optical Ethernet), xDSL, cable HFC, EPON/GPON,
and broadband packet radio (including WiMAX. Pseudo-Wire solutions not
only enables mobile wireless operators to use new packet access networks,
it also gives operators a choice among multiple packet network
technologies in the RAN, including Carrier Ethernet, xDSL, cable HFC, and
even broadband packet radio.)
