Spectracom offers Command Center Packages that address redundancy and diversity for the PSAP master clock. These packages include the PresenTense software package, which you can set up on your Domain Controllers to point to both NetClock time sources. If one NetClock goes off-line for whatever reason, your critical equipment is still synchronized by the other NetClock unit.
