2.5 PME-216i Packet Multiplexer Module
The Cyan Z-Series PME-216i module is an advanced, high-capacity Ethernet switch providing
MEF-compliant services with connection-oriented Ethernet transport. PME-216i I-Temp transport modules
are supported in the Z22, Z33, and Z77 multi-layer transport platforms for fiber efficient 10G transport
using 10GbE with OTN encapsulation (OTU2) options.
Each PME-216i module supports up to two 10G XFP interfaces for 10 Gigabit Ethernet LAN/WAN and
OTU2 connectivity, plus sixteen SFP interfaces for Gigabit Ethernet connectivity. The SFP ports support
both optical SFP and copper SFP modules. In optical SFP mode, it supports 1000Base-F and 100-FX mode.
In copper SFP mode, it supports 10/100/1000Base-T. You can disable auto-negotiation and provision the
port speed to 10, 100, or 1000 Mbps. Line sensing of Media Dependent Interface (MDI) and Media
Dependent Interface with Crossover (MDIX) in copper SFP port connections is automatic.
The PME-216i module provides 60 Gbps of Ethernet switching capacity. Connect a PME-216i line card to
another PME-216i line card across the backplane via a 20G interface to form a protection pair of line cards
supporting Link Aggregation Groups (LAG) and sub-50 ms restoration.
The PME-216i module supports VLANs at both the provider (802.1ad) and customer (802.1Q) level for
advanced Ethernet services. Support for Provider Backbone Bridge – Traffic Engineered (PBB-TE per
802.1Qay) provides connection-oriented Ethernet transport performance and scale. The module is MEF
compliant supporting EPL, EVPL, E-LAN, and E-VLAN services.
The PME-216i module supports Y.1731 end-to-end service OAM performance monitoring functions and
mechanisms enabled on UNI Flow Points. Y.1731 collects Delay Measurement (DM), Delay Variation
Measurement (DVM), and Loss Measurement (LM) necessary for Service Level Agreement (SLA) services
monitoring.
