Commercial Resale - Public Access Lines (PAL) Service - V1.0

History Log

Product Description

CenturyLink™'s retail telecommunication service, Public Access Line (PAL), is available for resale by Resale Customers to Payphone Service Providers (PSPs). Additional information about resale of CenturyLink's wholesale PSP service can be found in Commercial Resale – General PCAT.

PAL is a 2-wire, loop start business access line that is similar to Plain Old Telephone Service (POTS). PAL offers connectivity to the CenturyLink exchange network so the general public will be able to place telephone calls from public locations such as airports, schools, dormitories and correctional institutions.

A PSP who wants to connect their hardware to the exchange network will place the order for the PAL. Once the order connection is complete, access is provided to the network along with any elected screening and blocking. For required and option blocking values, refer to Blocking Procedure.

    Types of PAL services are:
  • Basic PAL - Provides a connection for your PSP's "smart" or instrument-controlled payphone to the CenturyLink Switched Network. Depending on the state, Basic PAL may be billed using a flat, measured, or message monthly rate. Measured or message rates may include a call allowance for a set number of local sent paid calls which are included in the monthly recurring charge.

    Basic PAL includes all functions associated with the CenturyLink network such as access to operator, sent paid (1+) service, N11 and 800/888 services. Coin collection and/or return of coins are controlled by the PSP's pay telephones.

  • "Guestline/ Coinless" Subscriber Service/Interexchange Carrier (IXC) Access Line – Provides a connection for your PSP's "smart" or instrument-implemented, coinless telephone to the CenturyLink Switched Network. Providing restricted access to the network, these lines are programmed to block direct dialed toll service. These services may also be billed using a flat or usage sensitive rate. Often used for courtesy phones or inmate facilities, Guestline/Coinless lines offer your PSP significant control of equipment usage.


Not all PAL services are offered on a resold basis throughout CenturyLink QC; refer to the state specific Tariffs/Catalogs/Price Lists for availability.
