MPOE/MPOP
- In most residence and small business situations, the MPOP and the first Network Interface are in the same spot. If MPOP and NI are separate, most tariffs require that the NI must be no more than 12" from the MPOP.
- “House” cable and inside wiring in each unit belong to the building, not CenturyLink. Therefore, the landlord or building owner owns all cable and wire past the MPOP in each building and all cable between buildings on the customer’s property. If they request that CenturyLink work on this cable or wire, CenturyLink will bill them for this work.
MPOP Locations:
- Single Residential Dwellings: the service interface point is located on an exterior wall of the residential structure.
- Single Business Locations: the service interface point is located on an interior wall of the business structure.
- Condominiums: the service interface point will be located at each building.
- Multi-Tenant Buildings: the MPOP is usually a single location or utility closet where regulated facilities enter the building. Beyond the MPOP, there may be multiple Network Interfaces (NIs) serving different apartments, suites, or floors.
- Campus Arrangement: on a campus, industrial park, or in a multi-building apartment or business complex, the MPOP is normally in the first building where Company network services are terminated.
