Type Alias: TelecomVersion

TelecomVersion = { kind: "d0"; } | { kind: "f6"; stamp: string; } | { kind: "unsupported"; stamp: string; }

Classification of the version stamp peeked from a raw Telecom message.

• "d0": the supported D.0 standard; decode the fixed header at D.0 offsets.
• "f6": the emerging F6 stamp; recognized but not decoded (different layout).
• "unsupported": no recognizable version stamp; the byte layout is untrustworthy.
