Tech Overview

Cisco Part Number: ASR-920-12SZ-D is a Cisco ASR 920 Series - 12 x 1/10GE SFP, DC Model

Introducing the Cisco ASR 920 Series Aggregation Services Class B Timing Compliance Router, a versatile converged access platform designed for Carrier Ethernet aggregation in business services and as a CSR/Small Aggregation platform for 5G mobile backhaul markets. These routers, fully compliant with ITU G.8273.2 Class B Timing specifications, provide enhanced accuracy utilizing Precision Time Protocol (PTP) for precise phase delivery. With their high throughput, small form factor, and low power consumption, these routers are tailor-made for mobile backhaul and business applications. The ASR 920 series offers a comprehensive and scalable feature set, supporting both Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact design. Service providers can efficiently deploy Multiprotocol Label Switching (MPLS)-based VPN services directly from the access layer.

Key Features of ASR-920-12SZ-D router:

  1. Broadband Access: The Cisco ASR 920 Class B timing routers facilitate broadband access, enabling the delivery of "any-play" services (voice, video, data, and mobility) to thousands of subscribers. Quality of Service (QoS) on these routers can scale up to accommodate a large number of queues per device. This extensive queue capability, coupled with a three-level hierarchical QoS algorithm, ensures an enriched broadband user experience. As a full-featured Layer 2 switch and Layer 3 router, it supports various broadband applications such as IPTV and Video on Demand (VoD), thus enhancing the Cisco Evolved Programmable Network (EPN) architecture.
  2. Converged Access for Mobile Applications: Deployed as a converged access platform for mobile backhaul, the ASR 920 router can aggregate multiple base stations via multiple Ethernet and IP interfaces, utilizing MPLS as a transport for mobile backhaul traffic. It also offers Synchronous Ethernet (SyncE) and IEEE-1588 timing services essential for today’s converged access networks. The ASR-920-12SZ-A /ASR-920-12SZ-D model features a pluggable GNSS receiver, which can function as a grandmaster clock for aggregating and backhauling small cell traffic. Its small form factor and durability in extended temperature ranges enable deployment in small, fully sealed cabinets in outdoor environments.
  3. Metro Ethernet Access: Built to meet service provider requirements for Carrier Ethernet access, the Cisco ASR 920 router is optimized for remote access and central offices, as well as smaller aggregation sites where a feature-rich, compact converged platform is essential. It provides service flexibility and offers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.

In conclusion, the Cisco ASR 920 Series Aggregation Services Class B Timing Compliance Router offers a robust solution for Carrier Ethernet aggregation and mobile backhaul, delivering high performance, scalability, and flexibility in a compact form factor, thus catering to the evolving needs of service providers in the 5G era.
