What is ISO 21806‑7 about?
ISO 21806‑7 is part seven of the multi-series standard that specifies the conformance test plan (CTP) for the data link layer for MOST, a synchronous time-division-multiplexing network, as specified in ISO 21806‑6.
ISO 21806‑7 specifies conformance test cases (CTCs) in the following categories:
- Network frames
- Allocation channel
- Protected system channel
- Timestamp channel
- Flow control
- Cyclic redundancy check
- Arbitration
- Default packet channel
Note-
Interoperability testing is not in the scope of ISO 21806‑7.
Who is ISO 21806‑7 for?
ISO 21806‑7 on Media Oriented Systems Transport (MOST) data link layer conformance test plan is useful for:
- Vehicle manufacturers
- Car infotainment manufacturers and developers
- Vehicle data services providers
- Developers of multimedia and infotainment systems
Why should you use ISO 21806‑7?
MOST enable the transport of high-quality service (QoS) audio and video together with packet data and real-time control to support modern automotive multimedia and similar applications. MOST is a function-oriented communication technology to network a variety of multimedia devices comprising one or more MOST nodes.
ISO 21806 series helps you implement the MOST communication technology into multimedia devices and to provide conformance test plans for implementing related test tools and test procedures.
ISO 21806-7 provides you with test setups for all conformance test cases that will help you carry out tests effectively.
ISO 21806-7 gives CTC that verifies that a network frame consists of a network indicator of type PREAMBLE, indicating the start of the network frame, followed by a number of data bytes.
ISO 21806-7 specifies the size and location test of protected system channel.
