Extended service portfolio

The Optical Refurbishment Center – long term partner of high qualified HW-Service for variant vendors of wired transmission and access technologies – has extended his service-portfolio and is up to now able to provide a full Maintenance Service (HW/SW) for Siemens EWSD systems in cooperation with it’s partner SilverEngine.


  • The TDM networks will migrate to VoIP but an efficient operation of the existing TDM networks must be ensured by the voice service providers over the next years.
  • A change to VoIP systems isn’t easy possible for Business ISDN customers because ISDN service characteristics are not available anymore and an „end-to-end“ communication of Business communication within a company based on VoIP solutions is still not enough standardized yet.
  • Agreements of spare part management and service for EWSD with the system vendors are mainly expired.
  • Experienced TDM specialists are limited available.


  • Increasing costs for maintenance of used EWSD technologies within the TDM networks
  • Rising default risk of existing TDM central offices
  • Retention of existing high quality standards and services of voice services for business customers

Our solution approach:

  • Ensuring of delivery and swap of high quality spare parts for EWSD
  • 24/7 maintenance of EWSD central offices (Level 1 / 2 / 3)
  • Economical optimization of existing TDM networks
  • Operation of EWSD central offices


As base of our extended service offer we have completed our ORC test lab with a complex EWSD system. The Maintenance service will be provided by German experts which have 20 to 30 years’ intensive experiences in telecommunication technologies of wired networks and worked for vendors like Siemens and NSN in worldwide support in past.


So we are able to offer the following services:

  • Level 1 - Level 3-Maintenance
  • 24h Emergency Support
  • Answer the technical questions
  • Problem solution
  • Project support like installation, integration, workshops and trainings
  • Crisis management, international communication with system development of Nokia, system sest und Project management
  • EWSD system upgrade

All service options could be ordered individual or as service package. We would be glad to communicate with you about your service requirements and to provide an individual offer.

ORC Survey: feedback is once again outstanding

In 2014, ORC repeated its customer survey as part of its quality control process. The survey delivered an average satisfaction rating of 1.57, a further boost from the 1.78 achieved in 2013.

This year’s survey was once again divided into eight criteria: availability, response time, sales expertise, product quality, range of services, value for money, delivery reliability and delivery time. Customers gave scores from 1 to 6, where 1 was "excellent" and 6 was "fail". The survey had a response rate of over 50 per cent.

“We’re honoured to receive such a positive rating from our customers, but we also have the obligation to do better”, says ORC CEO Andreas Fetzner. “We particularly appreciate the many constructive suggestions and ideas for improvement that we have received. This shows that our customers are abreast of the developments and trends on the markets, and have confidence in us in these areas.”
