Major Applications 

Cisco ASR 920 routers 

support broadband access for delivering “any-play” services (that is, voice, video, data, and 

mobility) to thousands of subscribers. Quality of service (QoS) on these routers can scale up to a large number of 

queues per device. This large number of queues, combined with a three-level hierarchical QoS algorithm, can 

deliver an enhanced broadband user experience. This full-featured Layer 2 switch 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 (EPN) architecture. 

Deployed as a converged access platform for mobile backhaul, the ASR 920 router can aggregate multiple base 

stations through multiple Ethernet and IP interfaces, and it can use MPLS as a transport for mobile backhaul traffic. 

It also provides the Synchronous Ethernet (SyncE) and IEEE-

1588 timing services required in today’s converged 

access networks. The model (ASR-920-12SZ-IM/ASR-920-12SZ-IM-CC) has a built-in GNSS receiver, which can 

act as a grandmaster clock for aggregating and backhauling small cell traffic. It also supports Cisco Universal 

Power over Ethernet (Cisco UPOE

®

) technology, which can be used to power small cell radios. The router can be 

deployed in small, completely sealed cabinets in outside environments, because of its small form factor and its 

durability in extended temperature ranges. 

Small cells deployments face challenges on the security front due to their location. The model (ASR-920-12SZ-

IM/ASR-920-12SZ-IM-CC) supports security service such as IP Security (IPSec) to help protect against 

vulnerabilities to subscriber traffic and the network. A built-in hardware crypto engine allows the feature to scale 

and makes it ideal for extensive small cell deployments. 

The Cisco ASR 920 router is built to meet service provider requirements for Carrier Ethernet access. It is optimized 

for remote access and central offices, for smaller aggregation sites where a full-featured, small-footprint converged 

platform is needed. The router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced 

L2VPN, L3VPN, and multicast services. 

Major Differentiators 

ASR 920 routers help service providers deliver differentiated, cost-effective services such as residential 

broadband, mobile, and Metro Ethernet. 

ASR 920 routers are designed with a 1RU compact form factor to accommodate deployment in small spaces. ASR-

920-24SZ-IM model is 1.5RU to accommodate the interface module in the chassis. Available with a range of 

mounting options, these routers can be deployed in space-constrained locations and cabinets. The extended 

temperature range supported by ASR 920 router allows them to be deployed in locations with minimal 

environmental control. In addition, their small footprint allows service providers to extend the reach of their Carrier 

Ethernet networks to more challenging and remote locations.
