NEC Corporation announced the launch of a new Service Aggregation Switch, CX2600/200 series. The new switch incorporates added TDM/ATM interfaces, as well as highly reliable maintenance operation functionality, making it ideal for next generation network construction.
The new features will enable carriers worldwide to carry out smooth mobile infrastructure backhaul [1] area migration, as they change over to an all-IP network.
Some of the features incorporated in the new switch are as follows:
1. Aggregation of diverse services and hybrid switching functions
The new hybrid switching capability of a single switching card simultaneously provides both effective packet switching for Ethernet/ATM traffic and low-latency circuit switching for TDM traffic. In addition, the new PWE (Pseudo Wire Emulation) function provides TDM/ATM emulation over IP networks.
In response to the need to move to an all-IP network in the future, NEC is providing an efficient migration to IP, which includes a phased introduction of the IP changeover in existing TDM infrastructure.
2. Maintenance operation function supporting highly reliable services
Fault detection, line fault localization and performance measurement of maintenance operation, which are issues with existing packet networks, have been broadly improved, contributing to improved service reliability.
3. Intelligent QoS control function
Through NEC's proprietary intelligent QoS control function, low delays and low jitter (delay variation) characteristics are achieved, enabling integration of different traffic quality requirements of each type of service or user contract in a single network. NGN construction, where fine communication quality of per-flow control is considered necessary, is also supported.
Recently, against the backdrop of a rapid increase in traffic through full-scale deployment of 3G/3.5G services and the introduction of WiFI/WiMAX technologies in the near future, there has been increased demand for mobile backhaul solutions that can realize both effective use of existing infrastructure facilities and upgradeability toward all-IP networks in the mobile infrastructure market.
The CX2600 series has been shipped since 2003 as a Layer 2 switch that achieves high level QoS control in broadband access areas, and in Japan, where the move to broadband has been advancing, it's been supporting and contributing to the development of fixed carrier's broadband infrastructure as a Service Aggregation Switch such as ADSL/FTTH access networks for consumer service and wide area Ethernet networks, L2-VPN for business network service.
NEC will offer solutions that can take on the multiple needs in the mobile backhaul areas, such as a solution aimed at expansion of the area of mobile services offerings through a combination of the PASOLINK Series of ultra-compact microware communications systems, with its track record of introduction in over 120 countries worldwide, and the CX2600/200 series, or a network solution that integrates a small space-type PWE gateway "CX2200 series" and is capable of achieving CAPEX reductions and which is highly suited to installation in wireless base stations.
These enhancements of functionality improve operations maintenance capabilities for mobile carriers worldwide, and provide migration to an all-IP network from TDM/ATM networks in mobile backhaul areas.
