Bellcore MIBs

Bellcore's single module here, INTERCARRIER-FR-MIB, isn't a piece of hardware at all but a Bellcore/Telcordia standards-era MIB (tied to the RFC 2233 generation of Frame Relay work) defining generic objects for monitoring Frame Relay service specifically at the handoff points between different carriers' networks. Its intended subject matter is circuit/service-level status at those intercarrier interconnection points, extending the standard DTE-side Frame Relay MIB (RFC 2115) to the multi-carrier case. Come to this page only if you're dealing with legacy intercarrier Frame Relay service handoffs and need the standards lineage for that specific interconnection-monitoring use case, since this bucket represents a telecom standards body rather than an equipment vendor. Because the public source for this module is sparse and undocumented, confirm actual object names against the compiled MIB before relying on it for live polling.
