during network consolidation


Comprehensive support services for network infrastructures while consoldating the network

Highly available and reliable telephony services form a key cornerstone for ensuring customer satisfaction.

However, since this is not a "self-run", especially during the phase of network consilidation, SilverEngine recommends and supports a holistic service for EWSD, hiE9200, hiS700 and NetManager along the product lifecycle.

Our service portfolio

SilverEngine offers a holistic service portfolio from analysis, monitoring and maintenance to upgrades and training.

The technological transformation of network infrastructures and, in particular, the consolidation of switches also impacts on the personnel situation at the telecommunications firms. To ensure a smooth telephony service, selected services related to the operation of the network can be outsourced to SilverEngine.

In addition to operations and preventive services, SilverEngine supports its customers in the event of network failures with comprehensive emergency support extending as far as disaster recovery support.

Test facilities during network consolidation

SilverEngine owns 2 EWSD test facilities. These are located in Leipzig and can be operated remotely.
