The present document specifies the Abstract Test Suite (ATS), the Abstract Test Method (ATM), ATS conventions, the
partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for testing the conformity of an
implementation to the BBCC specification of interfaces at the VB5.2 reference point between an Access Network (AN)
and a Service Node (SN). A proforma for the testing report (PCTR) is also included.
There are in fact two separate test suites, as well as two PCTR proformas, one version for testing the conformity of an
AN implementation, the other one for a SN.
