Symmetricom creates white papers that discuss the fundamental issues that companies face in relation to time management of their IT systems. These white papers also present the latest developments in technology and law affecting time management. To help you determine which white paper to download, we have written brief abstracts about each of them.
Cisco IP Telephony Clock Synchronization: Best Practices
More and more enterprises are using IP telephony solutions based on Cisco networking solutions. But many customers are overlooking an important part of the system architecture—the need to synchronize the infrastructure design with an external network time server. Proper clock synchronization is critical to ensuring good performance, improving troubleshooting, and producing accurate call detail records (CDRs) for billing. Download Now From Download Library.
Network Time Synchronization: 5 Essential Elements
Organizations today need network time synchronization that ensures the integrity of network operations and applications yet needs little in the way of management overhead. It’s hard to imagine a company that would knowingly tolerate only some of its processes running on time or only some of its timestamps being accurate — especially if they realize how easy and inexpensive good network timekeeping can be to accomplish. To make time both pervasive and accurate, five essential elements must be present: Download Now From Download Library.
5 Dangers of Poor Network Time Keeping
This white paper provides a compelling argument for having accurate and synchronized time in an IT infrastructure. It discusses the technical and business consequences that can occur when clocks in a network fall out of synch. Download Now From Download Library.
The Importance of Network Time Synchronization
As you read this, your network of workstations and servers, each with their own clock, are time stamping files, email, transactions, etc., all the while your server logs are recording every manner of transaction in the event you need that information. At some point during the day it is quite likely that automatic processes such as archiving, directory synchronization, cron jobs, etc. will execute and alter files based on time stamps. Fundamental to all of this is the belief that the time is correct. Even if the time is not absolutely correct there is often a belief that at least the time is “close enough.” This paper describes why “close enough” is no substitute for accurate network time and why network time synchronization is critically important.

It’s All in the Timing – Synchronizing the VoIP Network for Quality, Savings and Performance
As we accelerate into the New World of VoIP we assume we can leave some of the trappings of wireline telecom behind, such as the need for synchronization. After all, an IP network is about as asynchronous as it gets. While this may be true in some respects, precise time and synchronization continue to permeate many areas of IP telephony operations. Customer expectations of voice quality and service reliability remain unchanged, and as a result, the need for precise time remains unchanged though it manifests itself in different ways. The bottom line is that trying to design a VoIP network without considering network synchronization is probably the shortest path to realizing that you need it. Download Now From Download Library.
Stochastic Model Estimation of Network Time Variance
This white paper presents a study of clock drift in computers and other networked devices. The paper starts with an introduction to clock architecture, distribution of standard time, drift in oscillators, and efforts to improve clock precision. This is followed by an equation for clock drift that shows the how the calculation for modeling drift in networks was established. Finally, statistical projections are presented along with results and conclusions about the significance of network clock error, even in relatively small networks. Download Now From Download Library.
GPS Antenna Basics
This application note covers the basics of GPS antennas, installation and cables. The paper starts with the basics of why antennas are necessary and moves into the practical areas of installation and how to be the most successful in receiving satellite signals. Download Now From Download Library.
Complying with FDA's 21 CFR Part 11 Regulation: A Secure Time Management Primer
This white paper presents some of the key "time-integrity" considerations that will be critical for complying with this regulation and addresses issues surrounding electronic records, electronic signatures and time stamps. Download Now From Download Library.
Time: the Currency of Computer Crime
Definitions of what is computer crime matter less now that computers permeate everything. What does matter is how criminals and investigators use computer time. Criminals, victims and investigators all share one thing when it comes to crime involving computers. Everything that took place in a computer happened because a clock ticked. That means that protection and recovery (technically, legally and financially) require timekeeping that is pervasively and demonstrably accurate. Therefore, this white paper discusses why accurate time indexing, including the time stamping of events and the synchronizing of events to an accurate clock, has great potential to deter crime and investigate it.

A Hidden Security Danger: Network Timing - The role of accurate timing in reducing network security risk
This white paper looks at why it’s important for any network to keep its devices in sync and examine the security implications – and financial ramifications - of improper network time. It also explains an approach to keeping proper time that doesn’t require you to leave holes in your network defenses. Download Now From Download Library.
