| The Cisco® ASR 920 Series Aggregation Services Class B Timing Compliance Router is a full-featured converged access platform, positioned as a Carrier Ethernet aggregation platform for business services or as a CSR/Small Aggregation platform for the Mobile Backhaul for 5G markets. These 5G ready routers meet ITU G.8273.2 Class B Timing specifications and provides better accuracy using PTP for phase delivery. These high-throughput, small-form-factor, low-power-consumption routers are optimized for mobile backhaul and business applications. ASR 920 routers provide a comprehensive and scalable feature set, supporting both Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact package. They also allow service providers to deploy Multiprotocol Label Switching (MPLS)-based VPN services from within the access layer. |

The new Class B Timing Compliance Cisco ASR 920 Series routers come in a small form factor (1RU) and in the below configurations: Cisco ASR 920-12SZ-A fixed access platform with single AC power supply, twelve 1/10GE SFP interfaces, Timing (1PPS/10MHz/ToD) interfaces and pluggable GNSS module Cisco ASR 920-12SZ-D fixed access platform with dual DC power supplies twelve 1/10GE SFP interfaces, Timing (1PPS/10MHz/ToD) interfaces and pluggable GNSS module Cisco ASR 920-20SZ-M fixed access platform with modular AC/ DC redundant power supplies, twenty GE SFP interfaces, four GE copper interfaces and 4X10GE SFP+ interfaces and Timing (1PPS/10MHz/ToD) interfaces Prominent features Broadband access Cisco ASR 920 Class B timing 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. Converged access for mobile applications 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-A /ASR-920-12SZ-D) has a pluggable GNSS receiver, which can act as a grandmaster clock for aggregating and backhauling small cell traffic. 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. Metro Ethernet access 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. It also provides all the features required for MEF 3.0 service initiation, including services such as ELINE, ELAN, ETREE, ACCESS ELINE, TRANSIT ELINE. Flexible deployment options ASR 920 routers are designed with a 1RU compact form factor to accommodate deployment in small spaces. 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. Power-supply unit The new class B timing compliant routers support dual redundant fixed power supply module for DC(ASR-920-12SZ-D) & single fixed power supply module for AC(ASR-920-12SZ-A) PSU with front to back airflow. ASR-920-20SZ-M supports dual redundant power supply modules with front to back airflow and are field replaceable. Powered by the Cisco Carrier Ethernet ASIC Powered by the Cisco Carrier Ethernet Application-Specific Integrated Circuit (ASIC), which was designed specifically for service providers, ASR 920 routers deliver essential Carrier Ethernet technologies, including Hierarchical Quality of Service (HQoS), MPLS, and Virtual Private LAN Services (VPLS). This custom and advanced ASIC design provides uninterrupted line-rate performance while delivering complex services such as Access Control List (ACL) and HqoS. The Carrier Ethernet ASIC integrates Cisco traffic-management innovation to deliver intelligent packet-switching and routing operations. Service enhancement In ASR 920 routers, each service is assigned enhanced QoS and security attributes. The router provides advanced per-traffic-class metering and offers bidirectional packet-count and byte-count statistics. The service offering is enhanced with Operations, Administration, and Maintenance (OAM) functions that include Layer 2 Connectivity Fault Management (CFM), IP Service-Level Agreements (SLAs) for Layer 3, and MPLS OAM. |
