Publication of Customer Interface Specifications
Providers of Public Electronic Communications Networks (PECNs) are required to publish the technical specifications of their customer interfaces under the terms of the Radio Equipment and Telecommunications Terminal Equipment Directive (R&TTE, 99/5/EC). In agreement with operators and manufacturers working in the Network Interoperability Consultative Committee (NICC), Ofcom has produced the Guidelines for Interface Publication Issue 3.
The specifications of relevant interfaces provided by PECN Providers are available through the links below, which will take you out of the Ofcom web site.
If you have any queries regarding the contents of a Provider's specification(s), then these should be raised directly with the Provider concerned. Questions concerning Providers' publication obligations should be emailed to Neil.Nasralla@ofcom.org.uk
