4.9 App 9: Ethernet Services and Transport
The Cyan Z22 shelf is optimized for access aggregation and edge deployments. The system provides a
combination of Ethernet aggregation switching with connection-oriented Ethernet (COE) transport, OTN
encapsulation and DWDM in a single shelf.
The Z22 shelf extends high-performance Ethernet services and carrier-grade packet transport deeper into
the access network. The temperature-hardened Z22 system provides scalable aggregation of broadband
access platforms, fiber to the tower (wireless backhaul) applications, as well as business Ethernet and
residential deployments. The Z22 system supports standards-based COE and G.8032 to provide guaranteed
throughput for MEF certified E-Line and E-LAN services with sub-50 ms Ethernet protection switching.
