It specifies the following: - Physical layer service definition and protocol specification, - Data-link layer service and protocol, - Application layer service and protocol, - Network management, - Security, - Communication profile, - Wireless procedures and Gateway. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - enhancements to the performance statistics using key performance indicators (KPI); - "Stale Data" detection was added (see services Read stale data setpoints, Write stale data timer and Write stale data count setpoint).; - gateway commands were added; - a Quarantined State was added; - CCA Modes were extended to be more in-line with IEEE 802.15.4; - clarifications on whitelist and blacklist management were added; - clarifications on join (e.g. only require a single neighbor) were added; - clarifications on use of join links, table management, and defaults were added; - corrections and updates were made. The reader's attention is drawn to the fact that Annex M lists all of the "in-some-country" clauses on differing practices of a less permanent nature relating to the subject of this standard. The contents of the corrigendum of March 2021 have been included in this copy.
