ALLNET ALL-NTP-101 Rackmount NTP GPS Server 1U for Network Time Synchronisation

The ALLNET ALL-NTP-101 is a 1U rackmount NTP GPS server designed to deliver precise and stable time synchronization across IT environments. Using GPS-derived timing and the Network Time Protocol (NTP), this device distributes accurate timestamps to servers, networking equipment and security systems. Built for integration in racks, the unit supports continuous operation in data centers, telecommunications closets and enterprise network rooms where consistent timekeeping is required for log correlation, transaction ordering and regulatory compliance.

Advantages

The ALLNET ALL-NTP-101 combines GPS-based time reference with NTP distribution to provide high accuracy and reliability for network devices. Its compact 1U rackmount form factor allows straightforward installation in standard racks, while dedicated network interfaces enable simultaneous service to multiple clients. The server reduces dependence on external public time sources and improves internal time consistency, which aids forensic analysis, monitoring and automated processes that rely on synchronized timestamps.

Suitable for

• Data centers requiring centralized time distribution
• Telecommunications equipment and timing-sensitive network services
• Security and surveillance systems that need consistent timestamps
• Enterprise networks for log correlation and audit trails

Key specifications

• Form factor: 1U rackmount
• Time source: GPS-derived timing signal
• Protocol: Network Time Protocol (NTP) for time distribution
• Network connectivity: Ethernet interfaces for client synchronization
• Intended use environment: data centers, telecom rooms, enterprise networks

How to use

Install the ALLNET ALL-NTP-101 in a standard 19-inch equipment rack and connect the GPS antenna according to the manufacturer’s mounting and cable routing guidelines to ensure a clear view of the sky. Connect the device to your management network via Ethernet and configure NTP settings using the device’s web interface or CLI to add client access, define authentication and set stratum preferences. Monitor synchronization status and logs through the provided management interface and integrate address and firewall rules to permit NTP traffic from authorized clients.

Recommendations

Place the GPS antenna where it has an unobstructed view of the sky to maintain a stable time source. Use a dedicated management network or VLAN for NTP traffic to reduce latency and packet loss. Implement redundant time servers or fallback sources to improve availability, and regularly verify firmware and configuration backups to preserve accurate timekeeping.
