- New switch provides optimal solution for mobile backhaul
migration to all-IP Networks -
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. [2]
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.These products are on display at the 3GSM World Congress
being held from the 12 - 15, February in Barcelona, Spain.
