Brandywine Communications is a global leader in the design and manufacture of Network Time Servers (NTP Servers) and Precision Time Protocol (PTP) Time Servers and associated systems.

NTP - We offer a large line of Network Time Servers using NTP (Network Time Protocol). These NTP Servers provide a convenient and flexible means of accurately time-synchronizing computers, time displays, PBX's, and a wide variety of other equipment. All Brandywine Network Time Servers use GPS Network Time Protocol, or NTP for network time synchronization. These network time servers are secure, reliable and easy to install within your system as an accurate timing source. A GPS NTP server will give your company the necessary timing accuracy for military applications, hospitals, technology companies and many other utilities that demand precision timing to support network accuracy and efficiency.

For more information on Network Time Servers please see our NTP Server Matrix or go to our Network Time Server FAQ page.

PTP - Brandywine Communications has engineered a high end range of instruments utilizing the Precise Time Protocol (PTP). These products utilising IEEE 1588 PTP, can be used in many applications including TE, WiMAX, Ethernet Backhaul, Passive Optical Networks (PON), Circuit Emulation Services (CES), Electrical Power Distribution, Automation & Motion Control, Test and Measurement, and for many Military apps.
