2. Complete Detailed Product Overview

Product Line Positioning

Cisco ASR 9922 is the top-of-line flagship ultra-large modular chassis within the modern ASR 9900 next-gen IOS XR portfolio, positioned above the 30RU ASR 9912 as Cisco’s highest-capacity carrier core router platformCisco. It adopts a massive 44RU rack form factor with twenty high-density line card slots, dual next-gen RP3 control planes and up to seven independent fabric trays for maximum multi-plane forwarding redundancy, delivering industry-leading up to 96 Tbps total nonblocking full-duplex IMIX throughput. Engineered for strict 99.999% five-nines 24/7 unmanned tier-1 backbone reliability, it supports ultra-large ECC memory for global-scale BGP route reflectors, millions of concurrent BNG broadband subscriber sessions and tens of thousands of synchronized 5G transport pseudowires. It provides full backward compatibility with all ASR 9000 3rd/4th/5th-gen high-density fiber and OTN line cards, converging wireline broadband, mobile 5G packet core and hyperscale cross-continental DCI traffic on a single unified core backbone platformCisco.

Modular FRU Slot Architecture (Core Differentiators vs ASR 9912)

Dual Redundant A99-RP3 / RP3-X Route Processor Slots (Exclusive Next-Gen Control Plane)

Two independent hot-swappable FRU slots dedicated to A99-RP3 / RP3-X high-performance route processors, supporting Stateful Switchover (SSO), Nonstop Forwarding (NSF) and hitless ISSU zero-downtime firmware upgrades without traffic lossCisco. Each RP3 integrates high-performance multi-core industrial Xeon D x86 CPU, expandable ECC DDR4 memory, embedded partial switching fabric and complete multi-standard synchronous timing clock circuitry optimized for packet core and mass BNG workloads. Only ASR 9912 and ASR 9922 support RP3 series processors, delivering superior routing table scale and service processing capacity compared to RSP5-X/RSP880 on smaller ASR 9900 chassisCisco.

Memory tiers: A99-RP3-TR (32GB base, upgradeable to 128GB); A99-RP3-SE service edge variant with native large-scale BNG/CGNAT optimization.

Up to Seven Independent Fabric Card Trays (6+1 N+1 Multi-Path Data Plane Redundancy)

Seven separate hot-swappable fabric trays enable dynamic load-balanced multi-plane forwarding with six active fabric planes plus one spare redundant plane, eliminating all data-plane single points of failureCisco. Memoryless virtual output queuing fabric design avoids head-of-line blocking, with a unified shared hardware crypto resource pool providing consistent wire-speed MACsec/IPsec encryption across all twenty line card ports. The multi-plane fabric architecture enables linear throughput scaling up to 96 Tbps full-duplex system capacity, doubling the maximum throughput of ASR 9912.

Twenty Horizontal Hot-Swap Line Card Slots (Maximum I/O Density of Entire ASR 9000 Portfolio)

All twenty line card slots support OIR (Online Insertion and Removal) for in-service module replacement without chassis power cycle, fully compatible with the full ASR 9000 modern high-density line card portfolio for converged high-speed fiber + long-haul optical transport:

Ultra-high-density Ethernet line cards: 48×10GE SFP+, 12×25G SFP28, 8×100GE QSFP28, 2×400GE QSFP-DD, 1×800G QSFP-DD800 uplink modules
Optical transport line cards: OTN / SONET/SDH POS trunk modules for long-haul carrier backbone convergence

All line cards integrate distributed Quantum Flow Processor forwarding ASICs with dedicated hardware offload engines for L2/L3 forwarding, CGNAT, firewall, AVC DPI, MACsec/IPsec encryption and hierarchical H-QoS scheduling, with up to 4.8 Tbps per-slot forwarding capacity.

Integrated Multi-Standard Precision Timing Interfaces (Critical for 5G Packet Core & xHaul)

1 × GPS GNSS mini-coax input port for Stratum 1 PRTC grandmaster clock generation
