@ The new generation of ATM Switches

Now we are starting to see ATM switches at 50Gbit/s and scale up

BOSTON (US) - A new generation of ATM is coming, aiming to provide new carrier services end2end where quality is a must, and helping to consolidate the current network structures.
In the access network ATM is present in a vast majority of installations, ADSL in residential user environments and more recently SHDSL for professional environments providing voice and data using AAL1, AAL2 and AAL5. In the core network a new generation of ATM switches  has been developed for carriers in order to extend their existing networks and build new infrastructures to support Frame Relay, ATM, Internet and UMTS Installations.A year ago, routing vendors believed that there would be no need for ATM enabled switches to have a larger capacity than 40Gbit/s. Now we are starting to see the availability of switches that start at 50Gbit/s and scale up from there and provide new multi-service capability.  The new ATM multi-service switches have performances up to 450Gbit/s FDX switching capacity, STM1 to STM64 and Ethernet I/F, MPLS, IP routing capacities and have been announced by Alcatel, Lucent, Nortel and Marconi. 

Informed Opinion

"Since the downturn in capital spending began, carriers have been looking for ways to extend their existing networks, and that means building on ATM and frame relay installations, at least for the foreseeable future.... The ATM switches, the demise of which was predicted in 2000, have gained a whole new lease on life.”
(*)The Great ATM Switch Blitz Light Reading  (Jan 2002)

“I'm sure that ATM and IP will coexist for some time; indeed, that was the thrust of what I was trying to say. Coexistence isn't an option, it's a necessity: The carriers may be inclined to keep ATM as a dominant element in their infrastructure, but there's no sign of a similar sentiment by enterprises.”

@ AuroraForte success story

European Mobile Operators Choose AuroraForte for 3G Network Installation

HIGH WYCOMBE (UK) -  Trend Communications has recently secured significant orders for their AuroraForte ATM tester from major European mobile operators, with further interest being shown by many other 3G operators.

Mobile phone operators with 3G licences are now deploying the necessary network infrastructure, and require a new generation of test equipment that supports the use of ATM transmission protocol. For these operators the use of ATM is a new technology and they require portable, easy to use testers that provide a comprehensive capability of network Testing and Monitoring, as well as continuing support for their 2G networks. The tester has been chosen to analyse and commission the operator's 2G and 3G network infrastructure, and to enable comprehensive In-service and Out-of-Service testing of ATM performance throughout the network.

Key Features and Benefits

The following are the key reasons why the customer chose AuroraForte - the only comprehensive hand-held ATM tester that is ideally suited for use in the newly expanding 3G market.

Portability and Ease-of-Use

• Because AuroraForte is portable, and battery powered, it can be used in most telecommunications environments.
• Full Colour Graphical User Interface is quick, easy to learn and use – ideal for field staff and 3rd line support.
• New addition of File Management System allows results and configuration transfer between the tester and a PC using the built-in Ethernet port.

E1 and STM-1 Interfaces 

• Supports both the existing E1 network and soon to be installed STM-1 high-bandwidth networks.
• Plug-in network modules also provide E1 and STM-1 Bi-directional Monitor capability for trouble-shooting performance issues on a live network

@ New  Aurora Presto adds Autotest, G.SHDSL and TDR

Trend´s multilayer solution to cost-effective DSL roll-out

HIGH WYCOMBE (UK) -  AuroraPresto adds TDR/DMM physical layer testing, comprehensive G.SHDSL modem test functionality and Full Router Replacement mode to enhance its market leading DSL test capabilities.
 

AuroraPresto is the most comprehensive xDSL service tester available on the market today. Offering test capability at the Physical Layer, DSL layer, ATM layer, PPP layer and IP layer, the AuroraPresto has been adopted worldwide as the defacto standard for multilayer DSL installation, maintenance and troubleshooting. 

One Button MultiLayer AUTOTEST

The AuroraPresto is a comprehensive tester providing exceptional multilayer test capability. To allow installation engineers to benefit from the complete range of AuroraPresto test capability, a new profile based Autotest feature has been launched. This feature allows comprehensive test scenarios to be saved as test profiles by experienced users, then later utilised as part of a 'one button' test by installation engineers. Automatic session storage and results print out are provided if required. 

TDR/DMM

Fundamentally a TDR is a very simple instrument; a pulse is transmitted down a cable, which is then reflected back from any impedance mismatch that is encountered. The impedance mismatch may be caused by cable problems such as bad connections, a fault or simply by the end of the cable. The reflected pulse is sampled by the TDR and displayed as a waveform on the screen of the instrument. The AuroraPresto uses a graphical display to show the transmitted pulse and reflections that can then be interpreted as specific faults on the copper pair.

G.SHDSL

The majority of early G.SHDSL applications are two wire data applications using existing ATM / IP infrastructure from the DSLAM into the backbone network. The key to cutting the time spent deploying and maintaining G.SHDSL services lies with effective problem resolution. Effective problem resolution in turn depends on accurate fault location. The AuroraPresto provides comprehensive G.SHDSL test capability in addition to its already comprehensive ATM / IP test capabilities. 

Full Router Replacement Mode

AuroraPresto is unique in allowing users to completely replace the customer modem and monitor throughput statisticsat the ATM layer. To enhance this test functionality, the AuroraPresto can now also completely replace the functionality of a customer Router and monitor LAN / WAN throughput statistics.

@ FlexaNet remote Monitoring  through TCP/IP and  SNMP

FlexaNet is an ideal solution for distributed test and measurement

BARCELONA (Spain) - FlexaNet is a distributed monitoring solution based on Network Computing standards (SNMP, Java, SQL) to monitor networks based on SDH and PDH or MPEG video distribution.

FlexaNet is an ideal solution for distributed test and measurement providing a number of services for fault and performance management with non-stop 24/356 tracing capabilities. Web-based GUI enables distributed access to the results from anywhere, at anytime, with a simple Java-enabled Internet browser. Central managment of the monitoring resources is also possible, including topological control, summarizing real-time status of all the circuits, reporting, etc. FlexaNet is a vendor independent system which can be integrated in SNMP platforms to verify the provision of telecom services. Network Audit—The interconnection of networks, together with the appearance of new operators who use leased resources, has increased the need for contracts that define the Service Level Agreements (SLA). A good SLA must be transparent, precise and open for revision, so that it can accurately reflect the rights and responsibilities of both sides. It can provide real-time auditing of the network for Bandwidth providers and infrastructure owners.Differentiation—The most advanced operators know how to stand out from their competitors and attract new clients by offering them tools for verifying the Service Level Agreements continuously and without intrusions. 

FlexaNet fits the requirements of several businesses

1. Integrated monitoring of all the circuits of an operator using plant from many manufacturers, controlled in islands.
2. Supervision of interconnection agreements between two independent operators through a neutral system.
3. Third Parties who lease infrastructures from service providers and operators and need real-time information on the leased resources, but do not have access to the monitoring and performance control or inventory systems of the providers.
4. Service availability providing information on the hired circuits for the preferred clients of an operator.
