This Part presents an overview of protocol testing and CDPD ATS methodology.Basic Interconnection Tests (BITs) are used to reduce the likelihood that rogue implementations negatively impact the CDPD infrastructure. A more extensive test capability is provided by conformance tests, which exerci

However, these tests are not so restrictive as to contain implementations by manufacturers.Any conflict, either real or perce

35、The CDPD protocol test specifications consist of a number of interrelated “documents” for testing CDPD protocols. The following diagram illustrates the structure of the documentation. Figure 900-1 shows several documents for each of the protocols to be tested. For each protocol there is a common Pro

For asymmetrical protocols separate test suites exist for the user side of the protocol (end system) and the network side. For a symmetric protocol only one test suite exists.
