Resale - CenturyLink Inside Wire Maintenance (IWM) Plans - V19.0

History Log

Product Description

CenturyLink's retail Inside Wire Maintenance (IWM) plans, are available for resale by Competitive Local Exchange Carriers (CLECs) to their residential and business end-users. Additional information about the resale of CenturyLink's retail services can be found in Resale - General.

A Trouble Isolation Charge (TIC) is assessed when a CenturyLink Technician is dispatched to the end-users premises and the trouble is isolated to the end-users inside wiring, jacks, or Customer Premises Equipment (CPE). IWM plans are optional services offered to you for your end-users. End-users are not required to subscribe to IWM plans in order to have basic telecommunications service. When an end-user subscribes to a IWM plan, CenturyLink provides, at no charge, repair or replacement of damaged inside wiring or jacks. The plans can be requested on new or existing service, and are effective on the completion date of the request. On existing service, pre-existing trouble must be repaired prior to adding the IWM plan. CenturyLink's IWM plans, LineBacker™ and UniSTAR™ offer protection for inside wire or jack repair from the assessment of a TIC Trouble Isolation Charge (TIC), also known as Maintenance of Service Charge (MSC), resulting from a repair visit. Additional information on these two plans can be found in Tariffs/Catalogs/Price Lists.

IWM plans do not cover non-standard wiring . There are technical and industry standards for telephone wire required to ensure voice transmission. Non-standard wiring includes speaker wire, electrical wire and electrical cable. Standard wiring requirements are addressed in the Federal Communications Commission (FCC), Part 68 rules.

Continuous Property Extensions are covered on accounts having a IWM plan. Continuous Property Extensions are a single address location that is not separated by a public street, body of water, or public thoroughfare. Exchange Service Extensions (ESE), previously referred to as Different Premises Address (DPA), must be covered by a separate IWM for the ESE location. An ESE is an extension from the main service location to an address different from that of the main service location. They can be separated from the main service location by a street or public thoroughfare.

End-users or tenants in multi-tenant dwellings, such as apartment buildings and business complexes, should contact their property manager or building owner to determine if they are covered by an IWM. If not, CenturyLink does provide IWM plans to you for your individual end-users or tenants if requested.

CenturyLink offers the following IWM plans:

  • LineBacker™ is a residential IWM plan available in all states, for Resale Plain Old Telephone Service (POTS) and DSL (NOTE: Linebacker does not cover CPE associated with the DSL). LineBacker may be ordered for additional lines.

    UniSTAR is a per line, station line or trunk service, however, end-users are not required to have each line at their location covered by the IWM plan. A repair report on an uncovered line could result in the assessment of a TIC charge. Each circuit location or ESE extension requires a separate IWM plan.
