The decision covers 1.8 GHz-capable ICON3000 and ICON4000 amplifiers, together with Argus NMS and VDM, for Comporium's future HFC modernization.

ROCK HILL, S.C., and TURKU, Finland, Sept. 28, 2026 /PRNewswire/ -- Comporium, Inc., a diversified communications provider serving more than 145,000 customers across the Carolinas, has selected Teleste as the sole supplier of amplifiers and network management solutions for its future HFC upgrades following a competitive RFP process.

The selected platform combines Teleste ICON3000 line extenders and ICON4000 system amplifiers equipped with plug-in transponders, together with the Teleste Argus Network Management System and Virtual Device Manager (VDM).

Comporium's decision reflects the strengths of the complete platform. In the outside plant, the ICON amplifiers stood out for their RF performance, usability and speed of installation. In network operations, Argus, VDM and Teleste's amplifier telemetry were selected for their maturity, feature depth and operational value.

"During the field trial, we evaluated the amplifiers in our own plant and with the technicians who will install and maintain them," said Mike Deller, Senior Vice President of Engineering and Planning at Comporium. "The ICON3000 and ICON4000 exceeded the desired RF performance and stood out for their usability and speed of installation. That gave us confidence in Teleste as the amplifier platform for our future HFC upgrades."

The ICON amplifiers' plug-in transponders connect outside-plant telemetry to Teleste's management environment. VDM provides the virtualized device-management layer, while Argus brings centralized monitoring, alarms, diagnostics, remote control and device inventory into Comporium's operational workflows.

"Argus, VDM and Teleste's telemetry capabilities stood out for their maturity, feature depth and operational value," said Brian Bendt, Vice President of Network Services and Internet Planning & Development at Comporium. "The ICON amplifiers and the plug-in HMS transponders provide a standards-based foundation that integrates seamlessly with our network-management workflows. Together, these capabilities create a unified operational environment that gives our teams the visibility and the control they need."

"Comporium's decision is a strong endorsement of the complete platform," said Steve Condra, Senior Vice President of North America Sales for Teleste. "This was not a single-product selection. Comporium evaluated RF performance, field usability, telemetry and network management as one operational environment. Being chosen as sole supplier reflects the maturity of the platform and its ability to support the network strategy Comporium has defined. We are proud to have earned that confidence."

Future HFC upgrades and network expansion will use Teleste's ICON family of 1.8 GHz-capable amplifiers together with Argus and VDM. Deployment will follow Comporium's priorities as it advances its high-split modernization and prepares for a later transition to 1.8 GHz.
