This standard represents the PICS Proforma, per ISO/IEC 9646-7 and ITU-T X.296, for the conformance specification of base stations or access nodes, and access terminals or user terminals, based upon the air interface specified in IEEE Std 802.20.

This standard defines tester-independent conformance test procedures for Futurebus+. Specifically, this standard includes test procedures for verifying a module's conformance to the requirements of ISO/IEC 10857 : 19941 and sections 3 and 4 of IEEE Std 896.2-1991. This standard does not include test procedures for physical layer or performance-related requirements defined by the profile specification sections of IEEE Std 896.2-1991 or of any other Futurebus+ standards. Because the requirements contained in the non-profile sections of ISO/IEC 10857 : 1994 and IEEE Std 896.2-1991 are for the logical layer, this is primarily a logical layer test standard. Section 9 contains tests for those electrical requirements that are: a) part of ISO/IEC 10857 : 1994 and b) not profile specific. Since the majority of the requirements for the bus signaling environment are contained in profiles, the tests in section 9 of this standard are not, nor are they intended to be, a complete set of electrical tests for any Futurebus+ profile. Similarly, section 4 of IEEE Std 896.2-1991 contains mainly description and points to profile for the requirements governing the implementation of live insertion. Since this is the case, no live insertion tests are included in this standard. Readers interested in tests for these requirements should look to ongoing standardization efforts for Futurebus+ electrical and live insertion requirements and for Futurebus+ profiles. This standard is intended for use in verifying the conformance of Futurebus+ modules to the Futurebus+ family of standards. Some of the information may be useful in performing production tests and tests that measure a module's level of performance, but these types of testing are not within the scope of this standard. This standard is intended for the use of Futurebus+ manufacturers, users, and third-party test agencies. Use of a single test standard should allow different testers to arrive at similar test results.

This standard is applicable to the development and use of conformance testing methodologies for POSE standards. The generic test methods identified in this standard shall be used in conjunction with test methods identified for a specific standard. This standard is intended for use by working groups developing test methods for POSM standards, developers of POSM test methods, and users of POSIX test methods. The purpose of this standard is to define general rules for developing test assertions… read more and related test methods for measuring conformance of an implementation to POSE standards. Test methods may include POSM Conformance Test Suites (PCTS), POSE Conformance Test Procedures (PCTP), and audita of POSM Conformance Documents (PCD). Testing conformance of an implementation to a standard includes testing the claimed capabilities and behavior of the implementation with respect to the conformance requirements of the standard. Test methods are intended to provide a reasonable, practical assurance that the implementation conforms to the standard. Use of these test methods will not guarantee conformance of an implementation to the standard; that normally would require exhaustive testing (see 4.2.11, which is impractical for both technical and economic reasons. read less
