The Cisco ASR-9922-DC is a high-performance 20-slot DC chassis for the Cisco ASR 9000 Series Aggregation Services Routers, including Power Entry Modules (PEMs), fans, Route Processors (RPs), and Switch Fabric Cards (SFCs). This chassis provides a flexible, scalable platform supporting multiple combinations of Ethernet ports through modular line cards, enabling network scalability with lower initial costs and ease of upgrades.
Designed for demanding carrier environments, the ASR-9922-DC supports customer applications such as video-on-demand, Internet Protocol Television (IPTV), point-to-point video, Internet video, and cloud-based computing. It delivers economical, scalable, highly available, line-rate Ethernet and IP/Multiprotocol Label Switching (IP/MPLS) edge services, forming the fundamental infrastructure for scalable Carrier Ethernet and IP/MPLS networks that support profitable business, residential, and mobile services.
Key Features and Benefits
- Full compatibility with Cisco ASR 9922, 9010, and 9006 systems, route switch processors (RSPs), and line cards without requiring hardware upgrades to the chassis or cooling system. Total bandwidth depends on the number and type of RSPs installed.
- Ability to mix and match modular port adapters, allowing customization of each slot to specific port demands, such as combining 4-port 10-Gigabit Ethernet with 20-port 1-Gigabit Ethernet in a single slot.
- Simultaneous support for Layer 2 and Layer 3 services and features on each line card, enabling deployment in any combination of applications to reduce capital and operating expenses while accelerating service development and deployment.
- High service density for predictable, managed transport services with optimized network asset utilization.
- Synchronization circuitry and dedicated backplane timing traces for standards-based line-interface functions, supporting transport-class network timing for mobile backhaul and TDM migration. With Cisco RSP-440, supports IEEE 1588v2 synchronization services.
- Integrated media-monitoring technology for real-time monitoring and statistics collection of real-time video and voice flows, enabling proactive maintenance and management of interactive services.
- G.709 with Advanced Forward Error Correction (FEC) for consolidating IP and DWDM networking, providing visibility into DWDM transmission systems, rapid detection and recovery from impairments, proactive protection, and extended performance without regeneration or transponders.
Line Card Types and Capabilities
Cisco ASR 9000 Series modular line cards are available in Service Edge Optimized (enhanced QoS) and Packet Transport Optimized (basic QoS) variants, which can be mixed within the same system. Feature licenses enable advanced capabilities such as Layer 3 VPN (VRF instances), Advanced Optical (G.709 and FEC), and Advanced Video (inline monitoring).
Pluggable interfaces include a wide range of SFP, XFP, and QSFP options for 1GE, 10GE, and 40GE ports. Up to 2 modular port adapters per line card, supporting IEEE 802.3 compliant Ethernet with 10 Gigabit Ethernet PHY monitoring, IEEE 802.x flow control, full-duplex operation, and detailed per-port counters.
Line cards support line card online insertion and removal (OIR) without system impact, Carrier-class operations, administration, and maintenance (OA&M) including NetFlow, IEEE 802.1ag, IEEE 802.3ah, ITU Y.1731, IP SLA, VCCV, ping, and traceroute. Video monitoring (VidMon) provides real-time video flow monitoring with alarms on degradation.
Powered by modular, patchable, restartable Cisco IOS XR Software, the platform supports Synchronous Ethernet and IEEE 1588-2008 for precision time and frequency distribution across the network.
System Requirements and Deployment
The Cisco ASR 9000 Series Modular Line Cards deploy in 20-slot, 10-slot, and 6-slot chassis with Cisco IOS XR Software Release 4.2.0 or later. Maximum line card density: 20 in ASR 9922. Designed to meet NEBS Level 3 criteria, including SR-3580, GR-1089-CORE, and GR-63-CORE, with robust environmental tolerances for operating temperature (5 to 40°C nominal, -5 to 55°C short-term), humidity (10 to 85%), altitude, and storage conditions.
Compliance extends to ETSI, EMC, immunity, and safety standards such as FCC Class A, EN55022 Class A, UL/CSA/IEC/EN 60950-1, and laser safety. This ensures reliable performance in service provider environments for IP NGN deployments.
