Diplomat™-IP

DSLAM controller optimized to support Ethernet and ATM traffic for next-generation IP-DSLAM equipment; ideal for bandwidth intensive, triple-play services (TXC-06876)

Summary

The DiplomatTM-IP is a configurable Ethernet/ATM packet processor with an integrated MIPS control processor, comprehensive traffic manager and full switching capability for next-generation applications. The TR-101 standards-compliant device is a complete System-on-a-Chip (SoC) solution for DSLAM line cards. It is a feature-rich controller optimized to transport Ethernet and ATM traffic for next- generation IP-DSLAM equipment. The DiplomatTM-IP is particularly useful to broadband access OEMs seeking a low-cost, high-performance packet processor for high-density line cards. Its two GE ports provide flexible system connectivity with 1:1 protection, link aggregation, or daisy chain for protection/restoration, remote DSLAM and stacked DSLAM respectively.

The DiplomatTM-IP has a powerful packet engine for Layer 2 to Layer 4 wire-speed processing with capacity up to 3.2 Gbps and 4Mpps. It is highly integrated with best in class functionality including Ethernet bridging, stacked VLAN support and flow-based traffic management for advanced QoS handling.
