The Cisco ASR 900 Series delivers on the Cisco Unified Ethernet Access

vision by having a single product family with one software and system

architecture to enable service providers to offer Ethernet transport

services across access and aggregation networks for business access,

mobile backhaul, residential, and other deployments.

The Cisco ASR 903 Router is Cisco’s first product built specifically for the

pre-aggregation function in networks that target convergence of wireless

and wireline services. A natural extension to Cisco’s service provider

access and aggregation portfolio, the Cisco ASR 903 Router extends the reach of the portfolio with a small-

footprint, redundant, modular, and industrial temperature-hardened device.

The Cisco ASR 903 Route Switch Processor (RSP) provides the central control and forwarding capabilities of

the router with rich clocking and management interfaces. I/O connectivity is provided through hot-swappable

Interface Module (IM) cards. The IM cards can deliver DS-0 to OC-12 TDM/ATM and n x 10-Mbps Ethernet to n x

10-Gigabit Ethernet connectivity into service provider access and aggregation networks at wire speeds of up

to 55 Gbps.

The Cisco ASR 903 Routers combine Layer 2 and Layer 3 networking capabilities with a high-bandwidth, high-

performance architecture, including hardware-based forwarding of Circuit Emulation, Ethernet Operations,

Administration and Maintenance (E-OAM) protocols, Multiprotocol Label Switching (MPLS), Multiprotocol Label

Switching Transport Profile (MPLS-TP), IPv4, and IPv6.

The Cisco ASR 903 Router architecture, software redundancy and hardware redundancy provide a high-

availability platform. Additionally, the modular Cisco IOS XE Software facilitates In Service Software Upgrade

(ISSU).

Key Features and Benefits

• Flexible deployment options—The Cisco ASR 903 Router is designed with a 3RU compact form factor to

accommodate deployment in small spaces. Combined with various mounting options, the Cisco ASR 903

Routers can be deployed in space-constrained places such as ETSI 300mm cabinets. The side-to-side

airflow design allows for two Cisco ASR 900 Series Routers to be mounted back-to-back in a 600mm

cabinet. The wide temperature range supported by the Cisco ASR 903 Routers allows the router to be

deployed in locations with minimum environmental control. Small footprint and extended temperature

range support allows service providers to extend the reach of their Carrier Ethernet networks to various

types of locations and save money on air conditioning.

• High availability—The Cisco ASR 903 Router offers in-box hardware redundancy for all hardware

components and supports software redundancy with ISSU when two Route Switch Processors are

inserted in the chassis.

• Modularity—Cisco offers a choice of two Route Switch Processors (RSPs) providing different service scale

and a wide range of LAN and WAN Interface Modules (IMs). The LAN interfaces are available in copper and

fiber Ethernet interfaces with speed ranging from 10 Mbps to 10 Gbps. The WAN interfaces are available in

speeds ranging from DS-0 to OC-12. IMs, power supplies, and the fan tray are all modular and fully

upgradable when future generations are released.

• Industry standards certifications—The Cisco ASR 903 Router is certified for both Network Equipment

Buildings Standards Level 3 (NEBS3) and European Telecommunications Standards Institute (ETSI)

standards.

• Timing and synchronization services—The Cisco ASR 903 Router provides the timing services required in

today’s converged access networks to support mobile solutions, including Radio Access Network (RAN)

applications, and offers integrated support for the Building Integrated Timing Supply (BITS), 10MHz, 1 Pulse

Per Second (PPS), and Time Of Day (TOD) interfaces. The Cisco ASR 903 also supports synchronous

Ethernet (SyncE) and IEEE-1588, and it can also act as the source for network clocking information.

• Cisco Carrier Ethernet application-specific integrated circuit (ASIC)—Powered by the Cisco’ Carrier

Ethernet ASIC, designed specifically for the needs of service providers, the Cisco ASR 903 Router delivers

essential Carrier Ethernet technologies including: VLAN translation, selective QinQ, hierarchical QoS (H-
