PM5422 META-20G
Overview
Product Overview
The PM5422 META-20G is a feature-rich, high capacity, single chip solution that provides two universal 10 Gbps interfaces for Service Provider Routers, Carrier Ethernet Switches, Enterprise WAN, and Packet Optical Transport Platforms (P-OTPs). Designed with flexibility in mind, the META-20G offers the industry's first truly universal solution for 10 Gbps interfaces. Each 10 Gbps port may be configured to carry 10GE-LAN, 10GE-WAN, OTU2, or OC-192c/STM-64c (Packet over SONET/SDH) rate signals. The META 20G provides an array of packet mapping options needed by Router and Carrier Ethernet Switch line cards. The META-20G supports GFP multiplexing of up to 64 Ethernet (VLAN tagged and non-tagged) and IP/MPLS data streams into an OTU2. 10GE-LAN/WAN may also be mapped into an OTU2 in accordance with ITU G.709/G.sup43. Dual 10GE MAC/PCS and HDLC/PPP processors deliver a future-proof, line-card solution. The META-20G provides OEMs with an industry leading solution for Carrier Ethernet applications. Packet-based timing distribution via Synchronous Ethernet and IEEE 1588v2 (Precision Timing Protocol) is provided, along with 802.3ah Link OAM. Integrated support of these features enables the widespread adoption of Carrier Ethernet.
Benefits
- Dramatic Reduction in Capital and Operating Expenditure:
- Universal 10G ports enables a single line card to service multiple line-card applications, reducing development and inventory costs for equipment manufacturers and service providers
- OTN's Simplified Operation, Administration, and Maintenance (OAM) reduces the operational network cost
- Carrier Ethernet Ready
- Robust timing recovery and distribution with integrated SyncE and IEEE 1588v2/PTP timing support
- Integrated support for IEEE 802.3ah Link OAM
- Optimal Footprint and System Design Flexibility
- Integrated Carrier Ethernet features eliminate the need for external processors
- Universal port flexibility reduces power and space consumption versus comparable multi-device solutions
- Single 155.52 MHz clock operation reduces BOM costs
- Glueless interconnect to system side next generation packet platforms via Interlaken, XAUI, and extended XAUI as well as high-density line side XFP and SFP+(limiting) optics modules
