Axerra Networks announced the availability of a full-service
Pseudo-Wire backhaul solution positioned as an alternative to TDM access for mobile wireless operators, including those providing CDMA and EV-DO as well as GSM and UMTS services.
The Axerra AXN Pseudo-Wire solution combines circuit emulation, Frame Relay/HDLC/PPP, and Ethernet Pseudo-Wires in a single platform that has both n x T1 and Ethernet connections at the BTS to enable backhaul of every generation of wireless service, including CDMA plus 1RTT plus 1xEV-DO, and even CDMA 2000 or 4G, all over a single packet RAN. The solution also uniquely incorporates ATM with IMA, enabling GSM plus GPRS plus UMTS. Axerra said the resulting unified, high-capacity RAN reduces OpEx while enhancing the user experience for high-speed data services.
Axerra’s AXN Pseudo-Wire Gateways and Access Devices are currently installed and carrying revenue-generating traffic for operators on four continents.

| 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.) | |
