Integrated Timing Switch
The GM330 has it all, in a single unit!
Precision Time Protocol (PTP) is the standard that guarantees both phase and frequency alignment across the entire packet network. Packet network infrastructure relies on PTP to synchronize timing devices across the network.
Essential components of the synchronization architecture are the grandmaster, slave and boundary clocks. A Grandmaster clock provides standard time information to other clocks across the network A slave clock depends on the master clock for its accuracy, whereas a boundary clock can act as either a destination or source of synchronization information.
Protempis’s portfolio of products addresses all these needs.

Applications
Small Cells
In addition to its rugged design, the GM330 addresses the tight timing requirements of typical small cell private wireless services. As more radios and small cells are deployed to ensure coverage, the GM330 offers a scalable solution with its client count that seamlessly addresses the growing network’s time and sync needs.
4G LTE-A & 5G Services
The GM330 is a cost-effective solution for any network that requires stringent phase synchronization of 4G LTE A/5G services. With its high reliability and purpose-built design, it easily deploys at the edge and/or network aggregation layer.
Private 5G & Industrial Data Networks
Third-party providers and municipalities are building their own private 5G networks instead of relying on WI-FI to achieve superior range and coverage. The GM330, with proven time and sync technologies, enables these organizations to meet key connectivity requirements, while its integration of functions reduces implementation cost.
