Introduction
Precision Time Protocol (PTP) Support 3
Section 1.3
Precision Time Protocol (PTP) Support
The Precision Time Protocol (PTP) module adds the ability to provide time synchronization via Ethernet using
the Precision Time Protocol (PTP) and Network Time Protocol (NTP), and to synchronize with an external IRIG-B
source or GPS network.
The PTP module features BNC ports for AM IN/OUT, TTL IN/OUT and GPS IN. It also includes an LED to
indicate when synchronization has been achieved.
NOTE
The AM IN port is non-functional.
NOTE
The PTP module can only be installed in slot 1. For more information, refer to Chapter 3,
Communication Ports.

For more information about the BNC ports, refer to Section 3.4, “BNC Ports”.
The following sections describe the PTP support in more detail:
• Section 1.3.1, “Supported Time Synchronization Sources”
• Section 1.3.2, “AM and TTL Outputs”
• Section 1.3.3, “IEEE 1588 Support”
Section 1.3.1
Supported Time Synchronization Sources
The following time synchronization sources are supported by the RSG2488, with or without the PTP card:
