Distance Learning

Phonoscope developed the original mode of live and interactive distance learning for the Galveston Public School District, connecting eight elementary schools to the district's administration building using coaxial cable. Interactive videoconferencing technology, a cutting-edge solution for the time, significantly expanded access to education for students in Galveston. Phonoscope's involvement in its development dramatically contributed to the field of distance education.

"Since the company's inception, Phonoscope has recognized the transformative power of access to knowledge and the importance of providing educational opportunities for all. Our innovative approach to communications technology has been driven by a desire to connect people and bridge the gap between those who have access to educational resources and those who do not. By developing the first live and interactive distance learning system for the Galveston Public School District in the 1950s, Phonoscope helped to open the doors of education to students in remote and underserved areas. It paved the way for future advancements in the field of distance learning. Today, Phonoscope continues to prioritize education by providing cutting-edge communications technology to educational institutions and working to expand access to knowledge for all."

Public Communications Utility

The Texas Attorney General grants Phonoscope public utility rights for voice and video communications. This designation means that Phonoscope is one of 3 public communication utilities: Telegraph, Telephone, and Phonoscope.

Phonoscope brings telemedicine to the Medical Center

The introduction of telemedicine to the Houston Medical Center in 1985 was a true innovation and helped pave the way for the widespread adoption of telemedicine that we see today. This revolutionary technology allowed for real-time, interactive communication between cardiovascular surgeons and physicians worldwide. This was a major step forward in medicine, and Phonoscope played a significant role in making it possible. With telemedicine, patients had access to a broader range of specialists and treatments, while physicians could share knowledge, collaborate on complex cases, and improve the overall quality of care. It was a game-changer, and it demonstrates Phonoscope's commitment to improving people's lives through the use of advanced technology.

Fiber Optic Network

In 1989, Phonoscope achieved a major milestone with the completion of its large-scale fiber optic ring for ethernet transport. This significant achievement connected all major Houston business districts and the Medical Center through the use of high-speed, reliable fiber-optic technology. This meant that businesses in the city had access to faster, more efficient data transmission and communication, greatly increasing productivity and competitiveness. The Medical Center also greatly benefited from this infrastructure upgrade, as it allowed for faster and more reliable transfer of medical data and images, improving patient care and outcomes.This was a significant project that required a great deal of planning, engineering, and execution. Phonoscope's team worked tirelessly to complete this project on time, and the results speak for themselves. This fiber-optic ring was one of the first of its kind and it set the standard for other cities to follow. The completion of this project in 1989 demonstrates Phonoscope's commitment to innovation and its ability to execute on large-scale projects, which set the stage for the company to continue its growth and success in the following years.

🚀 The GigaBit Age
High-Speed Internet

Phonoscope launches high-speed internet, becoming the first to provide Houston residential customers with multi-internet speeds. Two years later, Phonoscope becomes Houston's first gigabit ethernet connectivity provider.


Phonoscope made another significant leap forward in the field of communications by launching its Voice over Internet Protocol (VoIP) service. This new service allowed customers to make phone calls over the internet rather than through traditional telephone lines. This was a significant development as it greatly increased the flexibility and cost-effectiveness of phone service. With VoIP, customers can make calls from anywhere with an internet connection and enjoy features like caller ID, voicemail, and call forwarding. The launch of Phonoscope's VoIP service marked a significant step forward in the company's history, and it helped to pave the way for the widespread adoption of internet-based phone service. This service was one of the first in the Houston area and proved that Phonoscope continued to be a leader in communications technology.

Gigabit to the Home

Phonoscope made yet another major advancement in communications by launching its Executive Gigabit Internet Service to the home. This new service offered lightning-fast internet speeds of up to 1 gigabit per second, making it one of the fastest home internet services available. This service was designed for power users requiring high-speed internet for gaming, streaming, and video conferencing. With this service, Phonoscope was able to provide customers with unprecedented speed and reliability, making it possible for them to enjoy the internet's full potential.

This allowed Phonoscope to offer a wider range of channels, more interactive features, and better picture quality than traditional cable TV. The IP headend also enabled Phonoscope to offer customers the ability to watch TV on multiple devices, such as smartphones, tablets, and PCs, and to access Video-on-Demand content. This installation marked the beginning of Phonoscope's transition to a fully digital, IP-based cable TV service.

Phonoscope Global

Phonoscope expands its reach by establishing Phonoscope Global, which focuses on providing IP-based services to Greater Houston and around the globe. Phonoscope Global enabled the company to offer a wider range of services, such as dedicated internet access, MPLS, VPN, Cloud, and Managed Services, to businesses, governments, and other organizations, allowing them to stay connected and competitive in the global market.

Fiber to the Home

Phonoscope established Phonoscope Fiber Communications to provide fiber-to-the-home (FTTH) services with symmetrical gigabit bandwidth and IP-based residential services such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Phonoscope Fiber Communications enables the company to offer a wide range of services, such as ultra-fast internet, high-definition television, and advanced phone services, all through a single fiber-optic connection to meet the increasing demand for high-speed internet and advanced communication services for residential customers.

Phonoscope Expands Fiber Optic Network to 20 Terabytes, Becoming the Largest Privately-Owned Metro Fiber-Optic Network in the Country

Phonoscope made a major expansion to its fiber-optic network by adding 20 terabytes of capacity to its existing 250 rings. This expansion allowed Phonoscope to offer unprecedented bandwidth to its customers, making it the largest privately-owned metro fiber-optic network in the country. Expanding fiber-optic wavelengths to 20 terabytes enabled Phonoscope to provide ultra-fast internet and advanced communication services to businesses, governments, and organizations in the greater Houston area, serving nine counties.
