The WR-Z16 implements the White-Rabbit (WR) protocol, an high-accuracy extension of PTP based on SyncE, that allows to easily distribute sub-nanoseconds timing within Metro Area Network distances and beyond. Worth to mention, that a timing network using WR protocol is not affected by the traffic load nor the number of hops.

Placed at the top of the rack the WR-Z16 can distribute standard PTP IEEE 1588-2008 for the last hop through its 16x fiber ports using the most common profiles such as Telecoms profiles (G.8265.1, G.8275.1) & Power profiles (IEEE C37.238-2011). It also provides NTP interoperability and 10MHz/PPS distribution.

To ensure continuous operation the WR-Z16 incorporates a failover mechanism. It provides a safer version of the “Best-Master-Clock” algorithm as it only allows switching over multiple (predetermined) timing sources when a failure is detected. Additionally, an optional Holdover oscillator can be included to maintain high accuracy (1.5us < 24h) even if all timing references are down.

The new version of WRZ-OS introduces a complete web interface redesigned to provide an excellent user experience: By the means of timing presets, a complex configuration can be done in a few clicks. Simultaneously, the CLI tool has also been rethinking to allow straightforward configuration from the terminal to advanced users.

The WR-Z16 enables extensive monitoring via SNMP including the combination of smart alerts with traps. By providing templates, it facilitates its integration within InfluxDB, Graphana and Zabbix tools. Moreover, it allows automatic topology discovery via LLDP and comprehensible remote logging through rsyslog.

TACACS+/RADIUS have been integrated to enable remote authentication for networked access control through a centralized server. The secure version of most of the protocols such as SFTP, HTTPS, SNMPv3 has been implemented and a firewall has been incorporated to provide a robust system against malicious users.
