Eastern Research MIBs

Eastern Research's MIBs in this database all describe modules and cards for the DNX digital cross-connect/multiplexer chassis, a legacy TDM transport platform: T1/E1/E3/T3 and STM-1/OC-3/STS-1 interface cards, DS0 drop-and-insert ports, octal high-speed serial and T1/E1 port cards, plus chassis-level nest/slot management, automatic protection switching (APS), and a System Management Controller for centralized alarm handling. Recurring data is squarely telecom transport health: per-circuit alarm/loopback/BERT diagnostics, ESF/G.826 error-second performance counters, and slot-level card presence and redundancy status across the DNX nest. Come here if you're maintaining an ERI DNX cross-connect shelf and need the vendor-specific objects for a particular interface card's framing, timing, or protection-switching state, since these MIBs go well beyond what a standard DS1/DS3 MIB exposes. Because each module targets one specific card type (e.g. HDS3, octal T1/E1, STM-1/OC-3), match the MIB to the exact card installed in the slot you're troubleshooting.
