EWSD
Overview
Consolidation of the EWSD component in the TDM-based network
Today, fixed-line operators face the challenge of actively steering the technological transformation from the traditional TDM-based network to the new IP-based broadband networks (next-generation networks = NGN) and managing the resulting risks in an active manner.
SilverEngine combines long-term experience in the operation of TDM networks required for this – especially in telephone switching systems (EWSD) – with comprehensive expertise regarding new technology. As a competent partner both in the consolidation of existing EWSD, S12 or other TDM-based exchanges and in the migration towards IP-based networks (NGN), SilverEngine offers flexible and individually tailorable solutions.
Our approach -
proven & sustainable
The consolidation process for TDM networks managed by SilverEngine considerably minimizes risks such as increased maintenance costs or a network failure – thus ensuring long-term customer loyalty.
For the prioritization of the consolidation, parameters such as the previous life time of relevant EWSD components as well as information as to whether the warranty has expired for certain components are taken particularly into account.
This approach contributes significantly to minimizing the failure risk of switches.
1 As-is analysis
Perform a technological audit and assess existing TDM switches as well as design consolidation of EWSD and S12 switching networks in the customer's TDM-network
2 Definition of steps towards the target architecture
Define the concept for consolidating TDM-networks as well as the concept for migration towards the target architecture
3 Transformation planning
Define consolidation sequence (taking the usage duration and the warranty for the components into account)
Create, adapt and pilot procedures
Verify the concept up to the network acceptance test4 Implementation of the network evolution
Implement pilot and series upgrades
Consolidate subscriber data and corresponding profile information
Consolidate switches and commission consolidated switches
Provide services accompanying the consolidation
Your benefits -
stable services and optimized costs
The consequent implementation of SilverEngine's proactive consolidation strategy offers fixed-line operators crucial advantages.
Optimized costs
Optimization of the maintenance and repair costs as well as energy costs for TDM networks
Stabile services
Secure provision of TDM services – especially ISDN services for business customers – for smooth and flexibly manageable migration to new technology
Reliable
Minimized failure risk of switchesFlexible
High flexibility in migration and consolidation of switches with a view to target technology
Automated
Automated consolidation through the use of a stable and tried-and-tested tool set (PConE) for database migration from n to m switches (whereby m can also be >= n)
Our PConE tool set
The consolidation of switches is a complex process in which adaptations repeatedly become necessary. In order to manage this process as effectively as possible, SilverEngine uses a self-developed and multiply tried-and-tested tool set (PConE) that convinces thanks to the following 4 arguments:
Create conditions for optimized network planning
Automated provision, updating and maintenance as well as targeted analysis of the database according to pre-defined parameters, consequent derivation of consolidation potential for maximum capacity utilization while simultaneously reducing switches in the network
Effective utilization of resources available in the network
Analysis of subscriber data and hardware at the source and destination switches, based on the data stored in the tool set, for the derivation of recommendations on the distribution of subscriber data and use of hardware components
Minimization of workload during migration phase
Automatic generation of command files for transfer and migration of the subscriber data
Efficient administration based on consistently current data
Transparent and consistent management of all parameters (subscriber data and corresponding profile information, hardware and software configurations of switches) with the ongoing option for access and updating
The automated process
with PConE
1 Export
Export entire database from the source and destination switches
2 Import
Import database into PConE
3 Mapping hardware data
Mapping of hardware data and definition of hardware requirements related to the destination switches based on guidelines provided by the network operator
4 Mapping software data
Mapping of software data based on guidelines provided by the network operator
5 Export of updated database
Generation and export of data files for expanding the database of the receiving switch
Automated
EWSD consolidation
In the specific case of the automatic consolidation of EWSD switches, the process is run through on an analogue sequence and comprises the steps described in the graphic.
1 Export
Implementation of the REGEN processes and export of log files, in which the changes in the switches involved are documented
2 Import
Import of the REGEN files and permanent integration of the current log files (log-file handling)
3 Mapping of hardware data
Hardware data mapping (e.g. setting the participant port for LTG, DLU and trunks in the receiving switch)
4 Mapping EWSD-specific configurations
Mapping EWSD-specific configurations (e.g. PA name, trunk name and unique ID handling for the receiving switch)
5 Generation and export
Generation and export of the command files for expanding the database of the destination switch
