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 proven approach
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.

ReliableMinimized failure risk of switches
High flexibility in migration and consolidation of switches with a view to target technology
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
Through the use of the PConE tool set, the consolidation of switches can be simplified and automated significantly.
Export entire database from the source and destination switches
Import database into PConE
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
Mapping software data
Mapping of software data based on guidelines provided by the network operator
Export of updated database

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.
Implementation of the REGEN processes and export of log files, in which the changes in the switches involved are documented
Import of the REGEN files and permanent integration of the current log files (log-file handling)
Mapping of hardware data
Hardware data mapping (e.g. setting the participant port for LTG, DLU and trunks in the receiving switch)
Mapping the EWSD-specific configurations
Mapping the EWSD-specific configurations (e.g. PA name, trunk name and unique ID handling for the receiving switch)
Generation and export
Generation and export of the command files for expanding the database of the destination switch
