BOUNDARY CLOCKS


Testing PTP Boundary Clocks

This paper looks at the key considerations when testing Telecom Boundary Clocks (T-BCs), a key element in deliverying accurate Sync for LTE-A and TDD-LTE. What is a BC and why it's needed. Why a BC needs to be tested.

T-BC G.8273.2 Conformance Test Plan

A ready-made test plan for Telecom Boundary Clocks to ITU-T G.8273.2 standard. This paper details the tests available to comply with G.8273.2. Calnex makes recommendations on what tests may be appropriate.

G.813 Wander Test Plan

This test plan details the test procedures specified in the ITU-T G.813 standard for wander performance of SDH equipment slave clocks (SECs). The test plan also explains how to use the Paragon-t to provide compliance to G.813.

T-TSC G.8273.2 Conformance Test Plan

The accuracy of Telecom Time Slave Clocks (T-TSCs) is essential to the successful roll-out of LTE-A and TDD-LTE. To meet the new G.8273.2 compliance limits, T-TSCs must meet a very stringent constant Time-Error (cTE) limit of 20 or 50 nanoseconds.

A guide to writing user-defined masks

The Calnex Analysis Tool (CAT) provides a range of pre-defined ITU-T masks to verify that the performance of network devices meets the relevant standards. The CAT also lets you define your own masks; this application note shows you how.

G.8262 Conformance Test Plan

A test plan for SyncE jitter and wander peformance to G.8261 and G.8262. This paper details the test procedures specified in the ITU-T G.8261 and G.8262 standards for Sync-E Jitter and Wander performance.
