ZyXEL-COE-MIB

Defines ZyXEL Central Office Equipment objects for DSL DSLAM management and subscriber provisioning.

ZyXEL-COE-MIB is a ZyXEL private enterprise MIB for Central Office Equipment (COE), covering ZyXEL DSLAM management and subscriber-line provisioning, placing it in the DSL access/central-office equipment category. It exposes configuration and status objects for DSLAM shelves/slots/ports and the subscriber DSL lines they terminate, spanning both provisioning, such as line profile assignment, and operational status. Its monitoring emphasis includes both chassis-level hardware status, such as card/slot presence and state, and per-subscriber line status, making it useful for tracking whether DSLAM hardware modules are healthy and whether individual subscriber lines are up and correctly provisioned. It typically works alongside a corresponding DSL line MIB, such as ZYXEL-VDSLLINE-MIB or a standard xDSL line MIB, that provides the detailed per-line performance counters, with COE-MIB providing the chassis/slot/provisioning context. It is typically deployed in central-office or cabinet DSLAM installations where ZyXEL COE equipment aggregates and provisions many subscriber DSL lines. Engineers can download the ZyXEL-COE-MIB file directly to load it into their MIB browser.

An operator would check the status of a DSLAM card/slot to confirm it is present and operating normally, then check the provisioning/line-profile assignment and operational status of a specific subscriber's port to troubleshoot a reported connectivity issue. A slot reported as missing or in a fault state would explain why an entire group of subscriber lines on that card are simultaneously down, versus a single subscriber line showing a provisioning mismatch when only one customer is affected. No sample objects were listed for this MIB, so exact table/column names are unconfirmed, but the functional data centers on slot/card status and per-line provisioning/status.
