The Calix C7 100-01930 RAP3 (Resource Arbitration Processor 3) is a powerful control card used in the Calix C7 Multiservice Access Platform. Its main role is to act as the brain of the system, managing traffic flow, timing, and system-wide coordination. Here's a breakdown of its key functions:

🧠 Core Functions

• System Control & Switching Matrix: It contains the switch matrix and real-time processor that handle all cross-connect and switching operations within the C7 shelf.

• Database Management: Maintains the system database in nonvolatile memory, storing cross-connect configurations and system software.

• Timing Source: Provides synchronization using a Stratum 3 holdover clock, supporting composite clock inputs.

🔄 Traffic Management

• Packet Switching:

  • 2.4 Gbps ingress (actual packet traffic)

  • 50 Gbps egress (optimized for multicast traffic)

• TDM Switching:

  • 1,056 STS-1 cross-connects for SONET/SDH traffic

  • 11,700 DS0 cross-connects for voice and legacy services

🧩 Distributed Architecture

• Works with other line cards to form a distributed packet switch fabric. This allows for:

  • Efficient traffic shaping and aggregation

  • Scalable packet processing across multiple Physical & Environmental Specs

    • Power Dissipation: ~45 Watts

    • Dimensions: 9.3" x 0.7" x 9.0"

    • Operating Temp: –40°C to +65°C

    • Compliance: NEBS Level 3, Telcordia GR-63
