Version before fields
JT/T and GB/T standards have editions and vendor profiles. A parser first checks framing and common headers, then applies only the selected or detectable version rules.
Local test data
Hex, SIP, SDP and XML samples are processed in this browser. Shareable URLs may contain input values, so use synthetic or redacted data.
- Remove vehicle identifiers and coordinates.
- Remove SIP passwords, nonces and public addresses.
- Do not upload production packet captures.
Testing and release process
Parser and converter functions are tested independently from the interface with known-good, malformed and boundary inputs. A release must pass type validation, regression tests and a static production build before representative English and Chinese pages are checked at desktop and mobile widths.
A sample that parses successfully demonstrates only the implemented byte path. It does not establish standards compliance, security, device authorization or end-to-end interoperability.
Source monitoring and controlled updates
Public standards portals and relevant RFC resources are checked by a scheduled monitor. A detected page or document change creates an email review alert; it never publishes new parser behavior automatically. An engineer must identify the applicable edition, compare the controlled document, update test vectors and review the bilingual explanation before release.
Corrections
Report the selected edition, message ID, safe sample frame, expected field value and the reason for the correction. Confirmed fixes receive regression tests.
