Digital Telecoms Testing

We can help you with Digital Testing for Integrated Services for Digital Network (ISDN) telephones, ISDN cards within datacoms systems and products with ISDN as a backup communications interface.

We are UKAS accredited to BS EN ISO/IEC 17025:2005, a Telecommunications Certification Body for the US and a Certification Assessment Body for Japan. TRaC has accreditations with ICASA (South Africa) and Telepermit (New Zealand), and our Telecommunications test reports are accepted around the globe, allowing easy access to alternative markets in addition to Europe.

Our extensive Digital Testing experience and assistance in standard development ensures that our services meet manufacturers’ expectations and help them gain access to international markets.

TRaC provides a wide range of regulatory and non-regulatory Digital Testing services covering electrical and protocol testing solutions. Our regulatory based ISDN testing ensures that your product meets with the requirements of the standard under assessment. This regulatory testing is based on assessing the performance of the lower three layers of the OSI 7 layer model.

The regulatory requirements for most countries are based on the Euro ISDN testing of ETSI TBR 3 and ETSI TBR 4 standards with country-specific requirements. For regulatory testing, TRaC has vast experience of offering ISDN analysis and developing test suites to assess ISDN devices to specific conformance requirements.
