MLTS Model Legislation
Recent technology innovations have made it important to update the MLTS Model Legislation recommended in 2000. The following revised Policy document reflects changes in IP technology; Implementation & Testing; Training and the use of building code Fire Zones to facilitate the creation of the Emergency Response Location.
A companion Technical Information Document (06-502) was created to aid in educating policy officials, government agencies and users of MLTS systems specific to E9-1-1 obligations. The accompanying Technica

Trunking for Private Switch 9-1-1 Service
This NENA TID defines three distinct alternative trunking configurations to accomplish the provisioning of Private Switch 9-1-1 Service (PS/911) in conjunction with the use of Private Branch Exchange (PBX) telephone systems. For PBX systems that use digital trunks, Primary Rate Interface Integrated Services Digital Network (PRI-ISDN) trunks, the provisioning of PS/911 may be accommodated without the requirement of dedicated trunks for transporting 9-1-1 calls. For PBX systems that use analog trunks (i.e. they are not compatible with PRI and/or PRI trunks are not available from local service providers), the provisioning of PS/911 may be accommodated by using dedicated circuits that operate with the Centralized Automated Message Accounting (CAMA) signaling protocol.
There are two CAMA alternatives that can be implemented; connecting the circuit to the Selective Router or connecting the circuit to the PSAP. While this document recommends using the PRI alternative for PBX sites served by PRI trunks, it is recognized that technical issues, tariff issues, or local conditions may determine that the CAMA alternative must be used. This document discusses how these configurations may be implemented, along with the issues and benefits of each alternative.
MLTS E9-1-1 Caller Location Discovery and Reporting
Recent technology innovations have made it critically important for organizations to address the challenge of identifying the location of the users of communications systems during emergencies in the Multi Line Telephone System1 (MLTS) environment. This paper and the accompanying diagrams will discuss many of the issues related to the location of individuals during emergencies in the MLTS environment. It will further outline the current suggested methods of dealing with the challenge using commonly available technology as recommended in this document by NENA.
Much public dialogue has taken place about locating individuals when they dial to signal that an emergency is in progress from cellular telephones or other mobile devices including Voice over the Internet Protocol (VoIP). Less discussed, yet as critically relevant is the large numbers of individuals who on a daily basis might use their office telephone or other device in an MLTS environment to dial for help.

Private Switch (PS) E-9-1-1 Database
Recent technical developments make it possible for Private Branch Exchange Telephone Systems (PBX) to provide Telephone Station level Automatic Number Identification (ANI). This NENA Technical Reference defines the requirements and methods to accomplish the provisioning of Private Switch 9-1-1 (PS/911) data in conjunction with the use of a Multi Line Telephone System (MLTS) or Private Branch Exchange (PBX) telephone system. For the purpose of this document and to be consistent with other NENA documents, a Private Branch Exchange telephone system or PBX will be referred to as a Multi-Line Telephone System or MLTS.
Enabling MLTS Owner/Operator Station or Caller Identification functions make true 9-1-1 for each MLTS Telephone Station possible. Where MLTS Station Level ANI has not been provisioned, the 9-1-1 callers location is unknown. This document identifies the responsibility that each MLTS Owner/Operator accepts when providing Private Switch 9-1-1 (PS/911).
