Study Group 15: Overview
General area of study is on “Optical transport networks and access network infrastructures”
SG 15 is the focal point in ITU T for the development of standards on optical and other transport network infrastructures, systems, equipment, optical fibres, and the corresponding control plane technologies to enable the evolution toward intelligent transport networks. This encompasses the development of related standards for the customer premises, access, metropolitan and long haul sections of communication networks.

Study Group 15 and the main Criteria for interoperability
6 Criteria developed by JCA-CITPosition of SG 15:
… are formally specified in SDL and ASN.1 for use with commercial tools …..typically those, incl. parameter values, are written in clear text … sufficient detail, parameter details and values …approx. 150 Recs comply …acc. to Supplement 1 to Recommendation X.290 …developed for Data Networks and Open System…contain: …Test Suite Structure and Test Purposes, ICS proforma, Implementation EXtra Information for Testing (IXIT) proformamost test work done outside SG 15 Interfaces for connectivity and testing fully definedapprox. 15 comply… are currently used in products in today’s marketSG 15 does not have this information

Example: xDSL
The Broadband Forum (previously known as DSL Forum) has a DSL testing and interoperability program consisting of:
Plugfests to aid the development of equipmentTesting of equipment by recognized independent testing labs per BBF testing specificationsDevelopment of testing specifications:

Example: Optical Transport
Key organisations performing testing: OIF and MEF. In general, these interopability events will involve testing interoperability of "capabilities". For OIF, the capability being tested may involve a collection of standards including ITU-T Recommendations, IETF RFCs, IEEE standards, and OIF implementation agreements. For MEF, it is generally MEF implementation agreements together with the relevant standards of IEEE or ITU-T (e.g., Ethernet OAM).Some publically available documentation:
