A900-CM-GNSS

Description

The Cisco A900-CM-GNSS is the ASR 900 Global Navigation Satellite System (GNSS) Clocking Module, a field-replaceable unit designed for Cisco NCS 4200 Series Route Switch Processors (RSP). It serves as a powerful centralized engine for network timing and control plane operations in Cisco NCS 4206 and NCS 4216 Series systems, addressing the demands of converged service provider networks including Carrier Ethernet, MPLS, and advanced timing services.

Key Features and Benefits

• Carrier Ethernet ASIC Integration: Delivers essential Carrier Ethernet technologies such as Hierarchical Quality of Service (HQoS), IPv4, IPv6, MPLS/Flex LSP, and Hierarchical Virtual Private LAN Services (HVPLS) with line-rate performance, innovative traffic management, intelligent packet switching, and routing.
• Service Enhancement: Advanced per-traffic-class metering, bidirectional packet-count and byte-count statistics, Layer 2 Connectivity Fault Management (CFM), IP Service-Level Agreements (IP SLA) for Layer 3, and MPLS OAM functionality.
• Service Scale: Flexible scalability in a small footprint for high-performance point-to-point and multipoint services in wireline and wireless applications.
• High Availability and Modularity: Supports optional intra-chassis hardware redundancy, In-Service Software Upgrade (ISSU), Field-Replaceable Unit (FRU) design, Online Insertion and Removal (OIR), and automatic switchover between active and hot standby RSPs.
• Management Interfaces: Out-Of-Band (OOB) interfaces including dual-mode USB/serial console port, Ethernet management port (RJ45, 10/100/1000Base-T), and USB port for flash storage.

Clocking and Timing Services

The A900-CM-GNSS module provides integrated support for Global Navigation Satellite System (GNSS), Building Integrated Timing Supply (BITS), 10 MHz, 1 Pulse Per Second (1 PPS), and Time Of Day (TOD) interfaces. It enables direct interface to external antennas and supports multiple satellite systems including Global Positioning System (GPS), GLONASS, GALILEO, BEIDOU, QZSS, and SBAS. As the central clocking source for NCS 4200 Series, it supports Synchronous Ethernet (SyncE), IEEE 1588-2008 (acting as ordinary clock, boundary clock, end-to-end transparent clock, or primary clock), and network clocking for TDM and SDH/SONET interfaces.
