Customized Routing - V18

History Log

Product Description

Customized Routing service is available to Competitive Local Exchange Carriers (CLECs) that purchase Resale services, from CenturyLink™.

Customized Routing service allows you to route your end-user's Operator Services (OS) (0+ Local) and/or Directory Assistance (DA) (555 or 411) calls differently than CenturyLink's end-user's calls originating on the same End Office switch. Customized Routing service permits you to identify and route particular types of dialing patterns of your end-user's calls that originate on CenturyLink's End Office switch to your dedicated interoffice trunk facilities, facilities leased from CenturyLink as Unbundled Dedicated Interoffice Transport (UDIT) or facilities provided by a third party. Such interoffice facilities may be terminated on your own DA and/or OS platform, on a third party's DA service and/or OS platform, or to CenturyLink's DA service and/or OS platform.

Customized Routing service is provided using software features of the End Office switch. A unique Line Class Code (LCC) is assigned to the end-user call type(s) you wish to have routed to the dedicated trunks and transport facilities you utilize.


Customized Routing service is available, where technically feasible, throughout CenturyLink QC and where switch software and facilities are available.

Customized Routing is not available for IntraLATA NPA 555-1212 dialing in the following states:

  • Iowa
  • Nebraska
  • North Dakota
  • Wyoming

Terms and Conditions

LCCs are a finite resource within the switch; therefore Customized Routing service will be available on a first-come, first-served basis depending on the availability in each of CenturyLink's switches. Development and deployment intervals for multiple LCCs and/or involving multiple CenturyLink switches are determined on an Individual Case Basis (ICB).

Some switch types and certain End Offices may have memory and technical limitations as to the number of LCCs that can be implemented. End Office capacity and technical limitations will be evaluated on an office-by-office basis.


Rate Structure

Customized Routing service requires complex and detailed programming of CenturyLinkŪ originating and End Office switches. This includes "Pre-Conditioning" of existing LCCs to allow deployment of the requested unique LCCs for your Customized Routing service request. Nonrecurring charges apply for this work.

If you have requested Customized Routing service and an LCC has been established and deployed at a particular End Office, and you wish to have the same LCC deployed at an additional End Office, nonrecurring charges for deployment at the new End Office will apply.


Wholesale rates for this product or service, including tariff references and any applicable discounts, are provided in your current Interconnection, Resale, Commercial, or other governing agreement.

The nonrecurring charges for the development and deployment of Customized Routing service and a new LCC for the routing of DA and OS traffic are provided in your agreement.

Nonrecurring charges to provision the LCC for individual end-users may apply, based on the type of service and activity you are requesting, after Customized Routing LCCs are deployed in a switch. Refer to Resale - General for additional information.

Monthly recurring charges do not apply to Customized Routing service.

Your CenturyLink Service Manager can assist you in filling out the form. A Customized Routing request is required for every end office requiring an LCC. Once the form(s) is completed, submit it to wsst@centurylink.com. Each request will be evaluated on an ICB.
  2. Based on the information submitted on your request form, CenturyLink will determine if facilities are available. The CenturyLink Service Manager will advise you by telephone if facilities are not available and will also advise you when to send a new request when facilities are made available.
