44、 strategy for the IPCablecom system. It will describe the elements of the system under test, the interfaces that may be tested and potential functional requirements for validation. Currently it is expected that testing will focus on two objectives: conformance testing to prove a component implements

45、 a particular protocol property and interoperability testing to prove a component from one vendor can seamlessly replace another vendor. The large body of specifications are analysed to examine areas that are affected by these two testing objectives, in the context of the business objectives of the

46、cable TV industry. The present document only scopes the size of the task so that the next step (generation of a system test plan or strategy specification) can be assigned adequate resources. Thus it focuses on identiSling critical components and interfaces for testing, sets priority for testing act

47、ivities and examines availability of commercial test systems. The present document does not define test environments, test cases, test scripts, test tools, test scenarios, test sequences, etc; that is the purpose of the test strategy. However, it should be noted that the job of designing a test plan

48、 should not be underestimated. The Packetcable architecture is similar to IPCablecom, except that IPCablecom defines in addition to Packetcable a V5.2 interface on an IPAT, ISDN-BRI interface on the E-MTA, NCS European analogue line package relevant to European PSTN line characteristics and lawful i

49、nterception interfaces specific to European needs. As of 2001, the Cable Labs Forum under their project, Packetcable, had defiied interoperability tests for 8 out of 11 areas (TGCP, ISTP, and security are still in definition), clearly such interoperability testing of functional requirements is beyond the scope of the ETSI intent. It is important to carefully narrow the nature of the testing intended for IPCablecom to conformance test requirements, defining a PICS, TP define which areas are more applicable to be conformance tested and those which would be best tested by
