When your company establishes new switching facilities or makes changes to existing facilities, you need new Common Language Location Identifier (CLLI) codes for the LERG and FCC NECA Tariff 4 systems. JSI Network Services can help you order the new CLLI codes through our agreements with NTCA (NTCA-member companies and their affiliates receive a discount) and the Telcordia® Common Language group. You can order CLLI codes directly, using our online form, or you can print the form and fax it to us.

For more information, contact Karen Hoffman (khoffman@jsitel.com) at 301-459-7590.
