  1. The Commission does not regulate interexchange telecommunications services. As explained below, retail tariffs are not required from carriers providing service to 20,000 or fewer subscribers.
  2. All applications for authority to provide regulated telecommunications services in the State must be made using the Application Form that is posted on the Commission’s website. Applications made in any other format will not be processed. The Application Form lists all requirements for filing. As noted on the Form, certain attachments are required to be filed with the Form. Forms that are incomplete or which do not contain the required attachments will not be processed. If Applicants have any questions or concerns with respect to this requirement, they should contact the Telecommunications Staff.
  3. Carriers providing retail service to more than 20,000 subscribers, carriers providing Switched Access Services, and Inmate Calling Service Providers will be required to file an initial tariff with its Application. Model Tariffs are included on the Commission’s website. In order to expedite the review process and ensure that all Maryland-specific tariff requirements are included, the carrier should use the Model Tariff. Any changes a carrier makes to the Model Tariff should be shown in legislative format as required by the Code of Maryland Regulations (COMAR) Section Proposed additions to an existing tariff are required to be underscored. Deletions must be shown in brackets or in strike-through text. Filings should include: (1) the currently effective tariff pages; (2) the proposed changes in legislative format; and (3) a clean copy of the proposed tariff. In addition to the marked-up tariff, carriers will also be required to file a clean copy of the tariff. The Telecommunications Staff will not consider tariff revisions that do not follow these requirements.
  4. Carriers providing retail service to 20,000 or fewer subscribers are not required to file a tariff with the Commission. These carriers must provide a website containing a pricing guide of service terms and conditions. A carrier must maintain a record of all changes to its pricing guide for no less than three years.
  5. The Commission routinely grants waivers of certain requirements contained in COMAR. Previously, the Commission granted different sets of waivers depending on the type of authority being requested. The Commission no longer regulates interexchange services and, therefore, only one set of waivers is currently applicable. The set of waivers granted to competitive carriers is listed on the Application Form.
