Today’s telecommunication network operators face significant business challenges. ... The solution to all these challenges is the EWSD Platform. The EWSD Platform is the high-performance, cost-effective and future proof solution for PSTN/ISDN networks
The solution is scalable from small to extremely large configurations and therefore adaptable to changing requirements. The EWSD Platform is grouped in core
and peripheral components. All components operate at the highest efficiency and at top performance while their high individual reliability combines to ensure the EWSD system is one of the most stable platforms available. Due to the modular concept of the EWSD
Platform you, as an operator, can configure each switch to exactly suit your requirements. The EWSD Platform, together with associated products, provides you with the ability to offer new and attractive services that open the door to further business and give you a stronger competition position. On top of all this, you only require one management system to control and supervise networks composed of EWSD and its associated products. ...
EWSD
EWSD® is the most successful digital switching system worldwide. Over 250 million EWSD-switched ports across the globe make us the number one supplier for carriers in this segment. With its extensive functionality, EWSD helps you build the network you want, in the market you want. ... And, of course, EWSD makes you ready for the Next Generation Network.
Features with EWSD :
_ New features for traditional POTS
_ Powerful ISDN features
_ Highly flexible CENTREX solutions
_ Carrier-grade Call Center solutions
_ IP-based applications
_ IN services
Traffic data measurement
Networks are subject to considerable fluctuation in the amount of traffic and unexpected external events. ... To record traffic data, the EWSD system provides integrated functions that can be operated without additional equipment or software:
_ Traffic measurement
_ Traffic supervision
_ Traffic structure measurement
Measurement data can be evaluated by programs such as SPOTS (Support for Planning, Operation and maintenance by Traffic analysis System). SPOTS is our performance management tool developed as part of NetManager, the EWSD management system, and is designed to help you reduce operating costs. ...
Four EWSD network solutions are setting the trends in modern TDM telecommunications
1. EWSD for network streamlining
. ... EWSD for all network levels
A best-in-class, flexible solution at local, transit, international, or all-in-one node.
EWSD, the most reliable platform (as proven by FCC statistics), is designed for
placement at any network level. EWSD is the solutions for
_ Local networks
_ Transit networks
_ International gateway networks
_ Combinations of all of the above
3.EWSD in deregulated markets
For interconnectivity to other carriers and to meet the requirements of regulatory
authorities – all you need is EWSD. ... EWSD and Next Generation Networks
EWSD opens your network to the IP world, from multimedia applications to CENTREX over IP – EWSD is the bridge to your Next Generation Network. EWSD is the solution for a risk-free migration to the Next Generation Network. ... EWSD, the most widely deployed switching system in the world does, however, ensure a smooth transition to Next Generation Networks. The EWSD DLU
and RSU access units represent a large amount of installed subscriber line cards (comprising the major part of your investment) and can be re-used as part of the Next Generation Access.
EWSD Platform
The EWSD Platform is the world-class solution that provides you with all the switching performance you need to master the challenges facing you. Thanks to its permanent evolution, EWSD provides the highest possible performance levels while its footprint and power consumption have actually declined by almost 60 percent in recent years. With EWSD your network is prepared for all future traffic and bandwidth demands.
EWSD – the all-in-one solution with unmatched switching performance.
EWSD performs all its functions on a single hardware platform. ... The EWSD Platform consists of the EWSD core and the EWSD periphery.
The EWSD core is comprised of the:
_ Switching Network (SN) – creates the connections between subscribers
_ Coordination Processor (CP) –performs call processing and routing
_ Signaling System Network Control (SSNC) – controls the SS7 signaling
traffic
The EWSD periphery is comprised of the following: -
_ Remote Switching Unit (RSU) –connects subscribers and trunks; can replace local
exchanges
_ Line Trunk Group (LTG) – connects subscribers and trunks
_ Digital Line Unit (DLU) – connects subscribers and concentrates the traffic to the
LTG
_ Synchronous Transport Module Interface (STMI) – provides a fully integrated STM-1
interface to the SDH network
_ Host Timeslot Interchange (HTI) –for connection of the RSU
EWSD Platform – prepared to meet future network demands.
Switching Network (SN)
The Switching Network is the base of EWSD switching. ...
Signaling System Network Control (SSNC)
The Signaling System Network Control (SSNC) is the high-performance EWSD component for SS7 signaling, supporting SS7 over TDM, SS7 over ATM and
also SS7 over IP. ...
The EWSD core – setting the standards in power and flexibility
Remote Switching Unit (RSU)
The Remote Switching Unit is one of the highlights of EWSD. ... This switching function of the RTI takes it possible for internal traffic to be directly switched through the RSU, avoiding traffic loads on the transport links to the host EWSD. ... 5 times higher performance
_ Optical or electrical interface to the Switching Network
Digital Line Unit (DLU)
With the newest Digital Line Unit, the EWSD Platform is perfectly prepared for the future. ... The RSDLU is also located remotely from the EWSD switch. ...
EWSD system periphery – greater efficiency in the access components. ... 25 interface
