Cisco ASR 900 Series Aggregation Services Routers Data Sheet
Available Languages
Cisco® ASR 900 Series Aggregation Services Routers are full-featured, modular aggregation platforms. They’re designed for the cost-effective delivery of converged mobile, residential, and business services. You get redundancy, a shallow depth, low power consumption, and high service scale in routers packed with useful features and optimized for small aggregation and remote Point-of-Presence (POP) applications.
The Cisco ASR 902 Router, Cisco ASR 903 Router, and Cisco ASR 907/914 Router (Figure 1) provide a comprehensive and scalable feature set, supporting Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in compact designs.
Major applications
Broadband aggregation
The modular Cisco ASR 900 Series router supports broadband aggregation for delivering “any-play” services (voice, video, data, and mobility). Designed to support thousands of subscribers, the ASR 900 Series includes Quality of Service (QoS) features that allow the routers to scale to a large number of queues per device. Combined with a highly granular, three-level hierarchical QoS algorithm, a large number of queues can result in a greatly enhanced broadband user experience. This full-featured Layer 2 and Layer 3 router supports a variety of broadband applications, including IPTV and Video on Demand (VoD), enhancing and extending the Cisco Evolved Programmable Network architecture.
Preaggregation for mobile applications
Deployed as a preaggregation platform for mobile backhaul, the ASR 900 Series router can aggregate cell sites and use Multiprotocol Label Switching (MPLS) as a transport for Radio Access Network (RAN) backhaul traffic. It also provides the timing services required in today’s converged access networks by offering integrated support for the Building Integrated Timing Supply (BITS), 10 MHz, 1 Pulse Per Second (1PPS), and Time Of Day (TOD) interfaces. The router also supports Synchronous Ethernet (SyncE) and IEEE-1588, and it can act as the source for network clocking for Time-Division Multiplexing (TDM), Synchronous Digital Hierarchy (SDH), Synchronous Optical Network (SONET), Synchronous Ethernet (SyncE), and Global Positioning System (GPS) interfaces. In addition, the ASR 900 Series router can be deployed in small and rugged environments, due to its shallow depth and qualification for extended temperature ranges.
Metro Ethernet aggregation
The ASR 900 Series router is built to meet service provider requirements for Carrier Ethernet aggregation. It is optimized for remote central office and smaller aggregation sites where a full-featured, modular, small-footprint, and fully redundant aggregation platform is needed. This router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
Major differentiators
The ASR 900 Series router helps service providers deliver advanced services for residential broadband, mobile, and Metro Ethernet applications. This allows an operator to provide differentiated and cost-effective services to end users.
Flexible deployment options
The ASR 900 Series router is designed with a compact form factor to accommodate deployment in small spaces. Available with a range of mounting options, the router can be deployed in space-constrained locations such as ETSI 300-mm deep cabinets. The side-to-side airflow design allows two Cisco ASR 900 Series routers to be mounted back-to-back in a 600-mm cabinet, while the extended temperature range supported by the router allows it to be deployed in locations with minimum environmental control. Small footprint and extended temperature range support allow service providers to extend the reach of their Carrier Ethernet networks to more challenging and remote locations, yet save money on air conditioning.
High availability and modularity
The ASR 900 Series router is a modular platform. Cisco offers a choice of multiple distinct Route Switch Processors (RSPs), AC and DC power supplies, a fan tray, and a wide range of interface modules. The Ethernet interfaces are available in copper and fiber, with speeds ranging from 10 Mbps to 100 Gbps. The legacy interfaces are available in speeds ranging from nxDS0 to OC-12/STM-4 for Plesiochronous Digital Hierarchy (PDH), SDH, and SONET. The interface modules, power supplies, and fan tray are all field replaceable.
The design of the Cisco ASR 907 and ASR 903 routers delivers in-box hardware redundancy and supports software redundancy with In-Service Software Upgrade (ISSU) support when a pair of route switch processors is inserted in the chassis.
Operational efficiency
The ASR 900 Series router features essential capabilities that help service providers simplify and automate the management of their networks, promoting efficiency gains in the deployment and operation of the networks. The router provides proactive diagnostic tools including Generic Online Diagnostics (GOLD) which help service providers avoid potential problems before they occur, troubleshoot any problems, and implement solutions when problems are diagnosed.
System design
The ASR 900 Series routers are built as fully modular systems with a future-ready design. The router chassis supports online field replacement and upgrades of all components. The Cisco ASR 907 Router is designed to contain one fan tray, up to three power supplies, two Route Switch Processor (RSP) cards, and up to 16 interface module cards. The Cisco ASR 903 Router is designed to contain one fan tray, two power supplies, two RSP cards, and up to six interface module cards. The ASR 902 Router uses the same design as the ASR 903 Router, but due to its smaller size, it has four interface module cards and one RSP card. All components support online replacement and field upgrades, with the exception of the RSP card on the ASR 902 Router, which requires the system to be brought down for a replacement or upgrade.
Fan tray
ASR 900 Series routers have a single fan tray slot, which must be populated for the system to operate. The fan tray contains redundant fans. The systems continue to operate on a single fan failure. The systems have been designed to remain operational during the replacement of the fan tray. The duration of the fan tray replacement has a hard time limit imposed on reinsertion of the fan tray depending on the system’s ambient temperature. In addition to cooling the chassis, the fan tray also contains a connector for dry-contact inputs and several system-level alarm LEDs.
The A902-FAN-E, A903-FAN-E, and A907-FAN-E modules all support an optional field-serviceable dust filter. The dust filter space of the A903-FAN-E and A902-FAN-E fan trays reduces their respective cooling capacity. This can result in a smaller operating temperature range for the total system, especially in combination with RSP3C and interface modules with more than 40G throughput capacity. Consult your account team for more details.
Power supply
A variety of AC and DC power supplies are available for ASR 900 Series routers. Depending on the system module configuration of a larger capacity power supply might be needed. The system supports operation on a single power supply, while two or more power supplies will function in a load-share configuration. Mixing of AC and DC power supplies in a single operational chassis is supported.
Route Switch Processor
The Cisco ASR 900 Route Switch Processor (RSP) is the centralized card in the system performing the data-plane, network-timing, and control-plane functions for the system.
The RSP engine form factor of the Cisco ASR 902 and ASR 903 routers is identical and can be moved between these two chassis types. However, the form factor of the Cisco ASR 907 RSP engine is different and can currently not be shared across different chassis types.
One RSP slot is provided in the ASR 902 Router, while the ASR 907 and ASR 903 routers have two RSP slots. The Cisco ASR 900 RSP is a Field Replaceable Unit (FRU).
Interface modules
Cisco ASR 900 Series routers have interface module slots. The Cisco ASR 902 Router contains four slots (slots 0 to 3). The Cisco ASR 903 Router contains six slots (slots 0 to 5), and the Cisco ASR 907/914 Router contains sixteen slots (slots 0 to 15). The supported combination of interface modules depends on the RSP and other interface modules used in the system as well as the chassis that is used.
Software
ASR 900 Series routers are supported in Cisco IOS® XE S Software, which is a modular operating system. This software is designed to provide modular packaging, feature velocity, and powerful resiliency. For more information on the supported features and software capabilities, see the Cisco IOS XE Software for Cisco ASR 900 Series Aggregation Services Router data sheet.
Network management
