The RIO and LIRO
For Providers that intend to directly interconnect with the ECAS and also provide Location Information the complete Reference Interconnect Offer (RIO) should form the basis of the contract between BT (providing the ECAS) and the Provider.
BT acknowledges that many Providers will be availing of transit services from third parties hence they will not be directly interconnecting with the ECAS although they will still be providing Location Information to the ECAS. The Location Information aspects form a subset of the RIO and for clarity this subset will be known as the Location Information Reference Offer (LIRO) and will form the basis of the contract between Providers not directly interconnected, but providing Location Information under the LIRO terms of this Agreement.
Structurally the whole of the document forms the RIO and the aspects that do not apply for the LIRO are provided in the ‘Definitions and Interpretation’ section, and as set out in Section 5 (“Scope”). Providers select whether they will contract with BT through the RIO/LIRO selection on the signature page of the main body of the agreement.
The RIO (of which the LIRO is a subset) is structured as a main agreement with five schedules attached detailing the various aspects of the service. Additionally four key technical specification documents are referenced by the RIO/LIRO.
A generic version of the ECAS RIO/LIRO contract and schedules can be found below.
