13-12-0814Network Operators, Service Providers and Public Safety should design broadband networks with the ability to take active measures to detect and restrict or inhibit any network activity that adversely impacts performance or security. This applies to Public Safety only in an NG9-1-1 environment.
13-12-0820Network Operators, Service Providers and Public Safety should deploy networks and services in a manner that mitigates the effects of harmful interference from other sources, and mitigates harmful interference into other services. This applies to Public Safety only in an NG9-1-1 environment.
13-12-0821Network Operators, Service Providers, Property Managers and Public Safety should coordinate to ensure that network deployment and equipment installation, including equipment moves, adds or changes (MACs), do not physically impair the operation of other collocated communications networks/equipment.
13-12-0822Network Operators, Service Providers and Public Safety should incorporate multilevel security schemes for network data integrity in the network design, as applicable, to prevent user traffic from interfering with network operations, administration, and management.
13-12-0900Network Operators, Service Providers should if operating a VoIP Positioning Center (VPC), Mobile Positioning Center (MPC), or Gateway Mobile Location Center (GMLC), strive to reduce missing or malformed shell record data routing errors for 9-1-1 pseudo Automatic Number Identification (pANI) due to incorrect Master Street Address Guide (MSAG) to Emergency Service Number (ESN) to Public Safety Answering Point (PSAP) relationship (MSAG-ESN-PSAP) by following National Emergency Number Association (NENA) 56-504 “NENA VoIP 9-1-1 Deployment and Operational Guidelines” to fully test routing for every pANI placed in service.
13-12-0901Network Operators, Service Providers and Public Safety should conduct extensive 9-1-1 call-through testing for environments that have a high user capacity (e.g., university campuses, large commercial enterprise campuses, and densely populated multi-tenant buildings/complexes) to immediately reduce the risk of misrouting a block of callers at a particular facility.
13-12-0902Network Operators, Service Providers should assess the impact on the routing of 9-1-1 calls when reconfiguring their networks. Such reconfiguration may include: making changes to VoIP Positioning Centers (VPCs), Mobile Position Centers (MPCs), Gateway Mobile Location Centers (GMLCs), and Emergency Services Gateways (ESGWs); rehoming trunking to Legacy Network Gateway(s) (LNGs); and/or establishing IP connections to Border Control Functions (BCFs).
13-12-1008Network Operators, Service Providers, Equipment Suppliers and Public Safety should use the Incident Command System for incident coordination and control in the emergency operations center and at the incident site.
13-12-1063Network Operators, Service Providers should set Initial Address Messages (IAMs) to congestion priority in accordance with applicable ANSI standards. This will ensure government emergency calls (e.g., 9-1-1, GETS) receive proper priority during national emergency situations. Implementation in all networks should be in accordance with ANSI T1.111.
13-12-1064Network Operators, Service Providers, Equipment Suppliers and Public Safety should implement minimum network management controls in order to promote reliability of the interconnected network. This applies to Public Safety only in an NG9-1-1 environment.
13-12-1068Network Operators, Service Providers, Property Managers and Public Safety should utilize Transfer Switch Equipment that conforms to industry standards.
13-12-1069Network Operators, Equipment Suppliers, Property Managers and Public Safety should consider marking or modifying copper bars and cable to deter theft, to make them easier to identify at scrap yards, and/or to reduce their value.
13-12-3203Network Operators, Service Providers and Public Safety should consider developing options that allow for call delivery from Emergency Notification Services to subscribers with call blocking/screening services in order to assist in the effectiveness of Emergency Notification Systems (Public Safety Mass Calling) and return calls from PSAPs.
13-12-3205Network Operators, Service Providers and Public Safety should consider participating in standards bodies and other forums contributing to Emergency Telecommunications Services (ETS) and NG9-1-1 related standards development.
13-12-3214Public Safety should support automated location query capability including rebids, but avoid the sending of overlapping location queries that would negatively impact current location determination capabilities.
13-12-3215Network Operators, Service Providers should in the absence of better routing information, route 9-1-1 calls based on cell sector/tower location toward the designated serving Public Safety Answering Point (PSAP) via the Emergency Service Network when necessary and where feasible.
13-12-3218Public Safety should provide training to educate PSAP personnel as to the process to obtain 9-1-1 Phase II data.
13-12-3219Public Safety should provide training to educate PSAP personnel as to the proper meaning and interpretation of the 9-1-1 Phase II display parameters.
13-12-3223Network Operators, Service Providers and Public Safety should implement dedicated and as diverse trunk groups as feasible and commercially reasonable as possible between the Mobile Switching Center (MSC) end office or similar source and the E9-1-1 Selective Router (SR) or Legacy network Gateway (for NG9-1-1), based on the geography served by the default Public Safety Answering Points (PSAPs).
13-12-3224Network Operators, Service Providers and Public Safety should use dedicated and diverse Signaling System 7 (SS7) or Multi-Frequency (MF) controlled trunk groups as feasible and commercially reasonable as possible for the normal routing of 9-1-1 calls from originating switching entities to 9-1-1 Selective Routers (SRs) or Legacy network Gateway (for NG9-1-1) rather than using shared Public Switched Telephone Network (PSTN) trunk arrangements and where appropriate and necessary supported by service level agreements. Network Operators, Service Providers, and NG9-1-1 PSAPs should use dedicated, geo-diverse and redundant IP connection points when feasible & commercially available.
