Network Cabling

Determining the optimal cable for your applications and ensuring its proper installation are integral to the successful infrastructure of your business. Shortchanging the process or installing cable without consulting a professional telecommunications company can wreak havoc for your business and incur expensive upgrades later. How can you be sure you've selected the right cable – and feel confident about its installation?  



After providing and installing your business telephone system, National Telesystems stays with you, offering the services to meet your unique business needs. As your business needs change, we're here to support your success, keeping your telecommunications quality consistent with your growth. As a one-stop shop, we're proud to offer a full-range of services.



We know you have lots of questions about buying a new telephone system. These are the ones we hear most often. Why use VOIP telephone systems? How much should they cost? What about warranties and service? Our goal is to help you make the most informed decision possible.




National Telesystems, Inc.

Years before businesses relied on the internet, National Telesystems was providing quality service to the Dallas/Fort Worth metroplex. For over 25 years, we have offered award-winning office telecommunications solutions, successfully serving over 11,000 businesses. We are proud to supply the highest quality telephone equipment and phone systems available – at the best prices available in the metroplex. But brand name equipment isn’t the most important factor in choosing a phone system. Your primary consideration should be the technology needed to implement your telephone system – and our tech team has the deep-dive experience to recommend ideal customized solutions for any business size.

Telephone System Services

While we deliver the highest quality telecomm products and the finest technology available – we know the hardware and the technology are only as good as the service it takes to keep them reliable. Your office system requirements are as unique as your business – and as a one-stop shop, we make it our policy to support our products with an all-encompassing range of business telephone system services and solutions.
