What is a Qualified Managed Facility Voice Network (MFVN)?
A Qualified Managed Facility Voice Network (MFVN) includes the following characteristics:
Has a physical facilities network which is managed and maintained (directly or indirectly) by the service provider.
Can ensure service quality from the service subscriber location to the public-switched telephone network (PSTN) or other MFVN peer network.
Utilizes similar signaling and related protocols as the PSTN with respect to dialing, dial plan, call completion, carriage of alarm signals and protocols, and loop voltage treatment.
Provides real-time transmission of voice signals, carrying alarm formats unchanged.
Provides professional installation that preserves primary line seizure for alarm signal transmission.
Has major and minor disaster recovery plans to address both individual customer outages and widespread events such as tornados, ice storms and other natural disasters. This includes specific network power restoration procedures that are comparable to those of traditional landline telephone services in the same geographic region.
Has informed ADT that its network meets the characteristics of a MFVN.
