Cisco 800-18572-02 454 Timing Control+ Card

Overview

The Cisco 454 Timing Control+ Card (part number 800-18572-02) is a high-performance timing and synchronization module designed for Cisco carrier and service provider platforms. It provides precise clock distribution, jitter reduction and seamless integration with existing network timing architectures. This card enables operators to meet strict timing requirements for voice, video and data services while simplifying network design and reducing operational costs.

Key Features

• Accurate timing distribution with sub-nanosecond jitter performance
• Supports multiple timing sources including GPS, IEEE 1588 PTP and SONET/SDH
• Redundant architecture for high availability and failover protection
• Hot-swap capable for zero-downtime maintenance
• Integrated diagnostics and monitoring via Cisco IOS
• Compact form factor fits standard Cisco chassis slots

Technical Specifications

• Form factor: 1RU card
• Power consumption: max 45 watts
• Supported timing protocols: GPS, IEEE 1588 PTP, SONET/SDH, NTP
• Clock accuracy: +/- 10 ppm
• Jitter: less than 20 picoseconds RMS
• Interface: 2 x 10/100/1000 Ethernet ports for management and control
• Operating temperature: 0 to 40 deg C
• Operating humidity: 10 to 90 percent non-condensing

Applications

• Carrier Ethernet and MPLS networks requiring precise timing
• Voice over IP (VoIP) and telephony systems that depend on synchronized clocks
• Video streaming and broadcast distribution where timing drift can affect quality
• Financial trading platforms that need ultra-low latency and accurate timestamps
• Utility and smart grid communications that rely on coordinated timing signals
