ASR 920 routers provide the timing services required in a converged access network to support mobile solutions, 

including Radio Access Network (RAN) applications. They also support SyncE with Ethernet Synchronization 

Messaging Channel (ESMC) and Synchronization Status Messages (SSM) to allow excellent clock-source 

traceability. In addition, the routers support IEEE-1588, and the ASR-920-12SZ-IM/ASR-920-12SZ-IM-CC model 

has a built-in GNSS receiver which can act as a grandmaster clock for aggregating and backhauling small cell 

traffic. 

Cisco ASR 920 routers feature major enhancements that help service providers simplify and facilitate network 

management, for reduced operational costs. With these innovative features, ASR 920 routers can be deployed in a 

variety of applications, including business services with 10-Gigabit Ethernet User Network Interface (UNI) and 

Ethernet mobile backhaul. The features enhance performance awareness, facilitate troubleshooting, and simplify 

service turn-up and restoration.

”Dying gasp” for power indicators and four external alarm inputs also detect 

changes in remote sites, giving service providers additional tools to manage the health of network elements. 

With all interfaces built in, this fixed-form-factor platform is versatile and can address many deployment scenarios, 

including Gigabit Ethernet and 10 Gigabit Ethernet deployments. The licensing mechanism allows additional 

1 Gigabit and 10 Gigabit Ethernet interfaces to be activated as required for a particular deployment, so service 

providers can customize the configuration of the device and pay only when their services grow. With support for 

extended temperatures, ASR 920 routers can be deployed in outside environments and remote locations. 

Cisco ASR 920 touters are supported in Cisco IOS

®

 XE 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 ASR 920 routers are supported in Cisco Prime

™

 for EPN architectures. The Cisco Prime end-to-end network 

management solution drastically simplifies the design, provisioning, and management of carrier-grade networks. It 

is a comprehensive solution that centralizes and automates service design, fulfillment, assurance, and 

performance analysis to help service providers and enterprises lower their costs while meeting high customer 

expectations. 

Interface modules supported on the ASR 920 routers are listed in Table 1 and Table 2.
