NetworkCounterpartySystemStatusRequest (MsgType BC)
NetworkCounterpartySystemStatusRequest is the FIX message with MsgType BC, defined in FIX 4.4. It is an application-level message: it carries a business event rather than managing the session. Its body has 5 top-level members once the standard header and trailer are counted.

Shown with | separators for readability. On the wire FIX uses SOH (0x01), an invisible control byte — and because BodyLength and CheckSum are computed over the actual bytes, the two forms have different checksums. Both are valid and both decode here.

Handle NetworkCounterpartySystemStatusRequest in TypeScript
import { createFixEngine } from "@boarteam/fix";import { dictionary } from "@boarteam/fix-dict-fix44";const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);if (message.msgType === "BC") { message.name; // "NetworkCounterpartySystemStatusRequest" // fields are keyed by tag; repeating groups live on message.groups}// Problems come back as data, never as exceptions:issues; // FixIssue[]fix.validate(message); // dictionary-level problemsDecode this in your own code
The same engine that produced the decoded example above is an Apache-2.0 npm package with zero runtime dependencies. It runs in Node and in the browser, and parse() returns problems as data instead of throwing.
