Real-world test and Standards Conformance for Ethernet Sync

Paragon-X and Paragon-100G are one box test solutions for Packet Sync, providing optional PTP (1588) Master and Slave emulation and SyncE wander + jitter support for fully controllable protocol and timing test, including industry leading precision for measurements and impairments. Paragon provides complete Standards compliance testing to multiple international synchronisation standards including IEEE, IEC and ITU-T.

Key Features and Benefits

Sync-over-Packet Standards Compliance
Enables design & verification engineers to prove synchronization standards compliance to the requirements defined in ITU-T standards. Proves performance by supplying all the essential capability & providing the highest measurement integrity and greatest efficiency. Integrated PTP Field Verifier and CAT tools provide instant Pass/Fail results for protocol conformance and timing performance.
PTP (1588)
One box Boundary Clock (BC), Transparent Clock (TC) and Ordinary Clock (OC) Test. PTP (1588) Master-Slave Emulation providing an integrated, accurate solution for PTP (1588) devices to standards such as ITU-T G.826x/7x (Telecom Profiles), IEEE 802.1AS/AS-REV (gPTP), IEC/IEEE 61850-9-3 (Utility Profile) and IEEE C 37 238 (Power Profile). In addition to standards-defined test cases, real world time error can be captured in the network and replayed in the lab for troubleshooting and case-by-case performance testing..
Sync-E
Prove Sync-E Jitter and Wander to ITU-T G.8262. at 1G-to-100G rates. Fully test hybrid PTP & Sync-E devices. Validate ESMC to ITU-T G.8264.
Automation with Script Recorder and Calnex Test Sequencer
Fast and easy automation by simple GUI button presses to automatically activate pre-prepared test scripts, or record tcl scripts ‘on-the-fly’, saves days and hours of test development time.

Time and Time Error

This Technical Overview discusses how time is distributed over the network, how Time Error affects network performance, and methods to mitigate Time Error to ensure accurate timing and synchronization throughout the network.

Multi-Clock testing

Running parallel test, or multi-point measurements in a test network, requires aligning and gathering data from multiple pieces of equipment, which is time-consuming and costly. Paragon-t allows up to 8 simultaneous clock measurements, providing faster, clearer insight and a greatly simplified test bed.
