DTS 4150.grandmaster is developed as a centralized system for airport applications, enterprise networks usually have a network consisting of a GPS synchronized main master clock, located in the main control room, and a number of sub-master clocks at various terminals. These master clocks then synchronize slave clocks and other IT systems in their environment, whereas the main master clock is connected with all sub-master clocks by means of the LAN/WAN and appropriate protocols (e.g. NTP/PTP).
DTS 4150.grandmaster is equipped with various transmission protocols for e.g NTP, PTP, SyncE & DCF77 (Current loop) passive output / 1PPS. To avoid time deviation between two DTS 4150.grandmasters, they can be linked via a fiber-optic connection by using two GBIC modules. Ideally, both grandmasters use GPS as primary time reference, but any time reference source can be chosen as primary time reference. The two grandmasters automatically negotiate their state as master or slave. The slave is synchronized by the master as soon as any better rated/prioritized source has a failure. Swap between master and slave state will occur automatic.
- PTP profiles supported are default E2E, P2P, utility (61850-9-3) & IEEE 802.1AS.
- High degree of synchronization redundancy by connecting up to 4 time sources: GPS, Link, PTP, DCF
- Supports NTP authentication for increased security, which allows the clients to verify the source of the received NTP packets.
- Alarms are reported via SNMP messages, e-mails and alarm relay.
