2. Complete Detailed Product Overview
Product Line Positioning
Cisco ASR 9001 is the compact 2RU entry chassis of the high-performance ASR 9000 IOS XR carrier router family, distinct from shallow-depth ASR 900/901/902/903 IOS XE mobile transport routers. It delivers fixed 120 Gbps nonblocking fabric capacity within a compact 2RU rack footprint, combining integrated RSP control/forwarding plane and two MPA high-speed fiber expansion slots, sharing identical IOS XR software feature parity with larger ASR 9006/9010 modular chassis. Optimized for carrier central office compact edge sites that require high-speed 10G/40G fiber port scalability, full carrier-grade hardware redundancy, synchronous timing for mobile fronthaul/backhaul and multi-tenant broadband aggregation without deploying large 4RU/6RU chassisCisco.
Fixed Native Front-Panel Ethernet Ports
All fixed ports support SyncE, IEEE 1588 PTP, MACsec hardware encryption, H-QoS offload and wire-speed CEF forwarding:
-
4 × fixed 10GE SFP+ slots for high-speed fiber uplink aggregation to core MPLS networks or data center DCI fabrics
All fixed ports accept SFP+ transceivers for single/multi-mode fiber and copper 10G RJ45 connectivity.
Modular MPA Expansion Slots (Two Hot-Swap Bays)
Two independent OIR-capable Modular Port Adapter slots, support mixed high-density fiber MPA modules for pay-as-you-grow port expansion:
-
MPA-4×1GE: 4-port Gigabit SFP for branch access aggregation
-
MPA-8×10GE: 8-port 10G SFP+ high-density multi-tenant access
-
MPA-2×40GE: Dual 40G QSFP uplink modules for large traffic aggregation
All MPA ports inherit full service-edge NP offload capabilities for NAT, firewall, AVC and multicast replicationCisco.
Integrated Precision Timing Subsystem (Carrier & Mobile Transport Critical)
-
1 × GPS GNSS input port for Stratum 1 grandmaster clock generation
-
1 × BITS RJ45 timing port compliant with GR-1244-CORE Stratum 3 carrier synchronization standard
Native support for SyncE, IEEE 1588v2 PTP telecom profiles, ToD and 1PPS clock signals to eliminate clock drift for 4G/5G mobile fronthaul/backhaul synchronous transport.
Fixed Management & Auxiliary Interfaces
-
1×10/100/1000BASE-T RJ45 out-of-band management Ethernet port for isolated remote chassis monitoring
