Quantum Bridge MIBs

Quantum Bridge (later part of Motorola) made broadband and optical access equipment, and its QB-* MIBs in this database reflect that: ATM PVC/soft-PVC signaling and PNNI topology, SONET/SDH transport (section/line/path overhead, APS switching, VT1.5 virtual tributaries), DS1/T1 circuit emulation, and network clock timing (BITS references) for an Optical Access System. Distinctively, Quantum Bridge's own QoS and VLAN features (QB-QOS-MGMT-MIB, QB-VLAN-MGMT-MIB) are built around policing/thresholding rather than the classic queuing or 802.1Q tagging you'd expect from a switch vendor, since these are broadband access-multiplexer features rather than enterprise switch features. Come to this page if you operate Quantum Bridge optical access or ATM aggregation equipment and need the vendor-specific PVC, timing, or SONET overhead MIBs alongside the IETF ATM/DS1/SONET standards those devices also implement. Several modules (QB-CESV2-MIB, QB-DWS-MIB, QB-VT15-MIB) have no confirmed populated runtime objects in this corpus, so verify object names against your device's actual MIB file before building polling around them.
