Multiline Telephone System (MLTS) Owners

Upload and Maintenance of Telephone Number Records

According to 30 V.S.A., Chapter 87, §7057 MLTS owners/operators are responsible for uploading and maintaining their telephone number records in the 9-1-1 Database. For additional information regarding compliance requirements for MLTS owners, go to the Multi-Line Telephone System (PBX/Centrex) Compliance with Enhanced 9-1-1 information sheet.

MLTS Owners have a few options for uploading and maintaining their records in compliance with 9-1-1:

  1. Working with the VT 9-1-1 Board’s Database Management Service Provider (DBMSP), Fairpoint, MLTS Owners can upload, view and maintain their records using a secure web interface (PSALI).  To receive more information about the Fairpoint WebDBMS, please contact Fairpoint  at (802) 951-1554 or E-mail.
  2. Several Vermont dial tone providers offer a MLTS database maintenance service as part of their PBX/Centrex service offering.  MLTS owners should coordinate with their dial tone provider to confirm that it offers such a service and determine the costs. 
  3. MLTS owners may opt to contract with a third-party database provider to upload and maintain their records in the 9-1-1 database.  A third-party database provider would need to coordinate with Fairpoint on gaining access to its secure web interface.  Please refer to for a list of vendors that provide this type of service. 

Regardless of which option is chosen, addresses are required to be validated against the Master Street Address Guide (MSAG) as part of the maintenance process to ensure a successful update to the 9-1-1 Database.  

Database Error and Resolution Reporting

ALI Discrepancies and Records not Found (RNFs) are reported by the PSAPs and Board staff, every business day, and are viewed by an Faipoint analyst in WebDBMS.  MLTS owners will be contacted directly by Fairpoint via email if they have any ALI Discrepancies and (RNFs) which need to be resolved.  MLTS owners, coordinating maintenance directly with their dial tone providers, will be contacted by their respective dial tone providers.  MLTS owners subscribing to a third-party database provider will be contacted by their vendor.  These discrepancies need to be resolved within one business day of receipt, or within three business days under special circumstances.
