TDM to VoIP – An Introduction

VOIP has, in many ways, revolutionized the way people communicate. The technology itself doesn’t get the credit, though. Rather, it’s the way many companies have leveraged their VOIP projects. They have used them to streamline their wide-area networks, standardize their voice infrastructure and calling features, unify their voice-messaging platforms, and implement collaborative applications that integrate in with their IP telephony systems. It’s a movement, more than anything, wherein VOIP is the first application in a broader strategy that unifies voice, data, and video communications.

But with these advancements come unprecedented network complexity and a lack of internal expertise on how to implement, troubleshoot and optimize the networks. During a time when IT staffs are lean to start, IT executives must bring their teams up to speed to manage their newly converged infrastructure and applications—starting with IP telephony alone. As such, a growing number of IT decision-makers are using or evaluating third-parties or Managed Service Providers (MSPs), to monitor and manage all or a portion of their converged networks, which connect a growing number of remote locations.

As companies migrate to IP Telephony (IPT), their support personnel soon discover the need for new monitoring and management tools (and often new skills), in order to deliver a reliable, high quality telephony service to their business – while also ensuring the IPT project achieves its planned rollout timeframes and ROI targets.

Unlike its predecessor, TDM (Time Division Multiplexing, a circuit mode communication used for telephony), IPT is not a closed, single application environment using its own network resources. Indeed, IPT infrastructure is more complex and involves many more moving parts. It is an integral component of an overall unified-communications infrastructure, where multiple applications compete for finite network resources.

Many IT managers view the task of managing IPT as being easier than it is. Up until recently, they haven’t spent enough time evaluating management tools, nor have they tended to budget appropriately – until they’ve had enough problems to force them into action. More recently however, IT decision makers are increasingly considering and evaluating monitoring and management tools such as PROGNOSIS earlier in their project timeline.

Whether companies are just starting, continuing, or finished with their IP telephony deployments, one thing’s for certain: They need to manage their newly converged networks. They must deliver voice traffic over the IP network in a way that is consistent and predictable, with sound quality on par with or better than TDM.

Many IT managers view that task as much easier than it actually is. As such, they don’t spend enough time evaluating management and monitoring tools, nor do they budget appropriately—until they have had enough problems to force them into a quick purchase to solve an urgent problem.
