Step 4: Interstate Access Support (IAS)

Interstate Access Support is available only to price-cap incumbent carriers (mostly non-rural and some rural carriers) and competitive carriers operating in the service area(s) of a price-cap carrier.

Filing Requirements

Required Data Filings

A "price-cap" incumbent local exchange carrier (ILEC) must submit to USAC the following information to be eligible for IAS:

  • line count information
  • revenue information
  • unbundled network element (UNE) zone rates, if UNE zones have been established
  • UNE zone maps, if UNE zones have been established
  • an IAS carrier certification.

A competitive carrier serving in the service area of a price-cap carrier must submit only line count data and a carrier certification.

A price-cap ILEC must file its Average Price Cap CMT Revenue per Line per month with USAC on an annual basis. Data as of December 31 each year is due no later than April 16 each year.
