The TimeMachines TM2000A GPS NTP+PTP Network Time Server represents a major step forward in capabilities at a breakthrough price point. It will supply accurate time for all computers and time keeping devices on the network. Supporting both precision time protocol (PTP) and network time protocol (NTP), a Stratum 1 time source can now be available on the local network with no need for an internet connection. SNMP V2/V3 is supported on the device, authenticated NTP, Peer NTP lookup, and Manual time setting modes. The TM2000A NTP and PTP time server uses an active GPS antenna to maintain the current time as broadcasted by United States GPS satellites planet-wide.
In addition, a high stability OCXO reference clock is included that allows the unit to serve time if GPS lock is lost for periods of time. This NTP and PTP time server is small and can be placed anywhere within the network layout. The built in high sensitivity GPS receiver is able to lock multiple satellites from within many buildings or from a window location, often removing the requirement that outdoor antennas be installed in every application. Outdoor antennas are available from TimeMachines including custom length cables and accessories.
