Major Applications

TDM/SONET/SDH Migration to MPLS/IP

The ASR 900U Series routers have rich MPLS features, high performance, and IoT Interface Module (IM) support that enable the migration from TDM/SONET/SDH to MPLS/IP. They support MPLS-TE, MPLS-TP, and FlexLSP (RFC 7551) features that enhance various types of services such as data, voice, video, and circuit emulation. They also support fast reroute capability to achieve high resilience for critical operational processes.

The ASR 900U Series routers also provide the timing and synchronization services required in today’s converged MPLS/IP 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 routers support Synchronous Ethernet (SyncE) and IEEE-1588 PTP, and they 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-920U-12SZ-IM router has a built-in GNSS receiver, which can act as a grandmaster clock.

Industrial IoT

The Cisco ASR 900U Series routers support IoT interfaces: Sync/Async Serial, C37.94, and E&M. These interfaces enable industrial IoT use cases such as teleprotection, SCADA, and so on for power utility, transportation, oil and gas, and other industries. Timing synchronization features mentioned in earlier sections make sure of deterministic processes to be reliably and accurately synchronized and transported. The Cisco ASR 900U Series is compliant with power utility standards, including IEEE 61850-3 and IEEE 1613.

Multiservice Network Convergence

The Cisco ASR 900U Series routers support broadband aggregation for delivering “any-play” services (voice, video, data, and mobility). Designed to support thousands of subscribers, the ASR 900U 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.

Metro Ethernet Aggregation

The Cisco ASR 900U Series routers are built to meet industrial IoT requirements for Carrier Ethernet aggregation. It is optimized for remote control centers 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 900U Series routers help enterprises deliver advanced services for operation processes, voice, video, and data applications. Converged MPLS/IP networks allow network operators to provide differentiated and cost-effective services to end users.

Flexible Deployment Options

The ASR 900U Series routers are 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 300mm deep cabinets. The side-to-side airflow design allows two Cisco ASR 900U Series routers to be mounted back to back in a 600mm 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 enterprises to extend the reach of their MPLS/IP networks to more challenging and remote locations, yet save money on air conditioning.

High Availability and Modularity

The ASR 900U Series routers are modular platforms. 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 10 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 903U 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 900U Series routers feature 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 routers provide 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 900U 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 903U Router is designed to contain one fan tray, two power supplies, two RSP cards, and up to six interface module cards. The ASR 902U Router uses the same design as the ASR 903U Router, but due to its smaller size, it has four interface module cards and one RSP card. The ASR 920U Router is designed to contain embedded RSP, one fan tray, two power supplies, and one interface module card. All components support online replacement and field upgrades, with the exception of the RSP card on the ASR 902U Router, which requires the system to be brought down for a replacement or upgrade.

Fan Tray

ASR 902U and 903U 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 and A903-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. Consult your account team for more details.

ASR 920U-12SZ-IM has a single fan tray slot, which must be populated for the system to operate. The fan tray of ASR 920U-12SZ-IM is field-replaceable.

Power Supply

A variety of AC and DC power supplies are available for ASR 900U Series routers. Depending on the system module configuration, a larger capacity power supply might be needed. The system supports operation on a single power supply, while two 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 900U 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 902U and ASR 903U routers is identical and can be moved between these two chassis types. One RSP slot is provided in the ASR 902U Router, while the ASR 903U router has two RSP slots. The Cisco ASR 902U and 903U routers work with RSP2A,which is a Field-Replaceable Unit (FRU). The ASR 920U-12SZ-IM Router contains an embedded RSP.

Interface Modules

Cisco ASR 900U Series routers have interface module slots. The Cisco ASR 902U Router contains four slots (slots 0 to 3). The Cisco ASR 903U Router contains six slots (slots 0 to 5). The ASR 920U-12SZ-IM Router contains one slot (slot 1). 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.
