PRIME FiBER picks COS Systems for Sun City wholesale fiber rollout

By AI, Created 1:23 PM UTC, May 16, 2026, /AGP/ – PRIME FiBER has selected COS Systems to support wholesale operations and AT&T integration for a new fiber market in Sun City, Arizona. The move is part of PRIME FiBER’s broader expansion across the Phoenix area and aims to speed up launches through more automated partner workflows.

Why it matters: - PRIME FiBER is using software to reduce the operational friction that often slows open-access fiber launches. - The Sun City rollout is part of a broader wholesale expansion in the greater Phoenix region. - Better orchestration between infrastructure owners and retail service providers can shorten launch timelines and reduce manual coordination.

What happened: - PRIME FiBER selected COS Systems and its COS Wholesale Engine to support wholesale operations and integration workflows. - The platform will support PRIME FiBER’s expanding partnership with AT&T in Arizona. - The deployment is tied to PRIME FiBER’s new fiber market launch in Sun City, Arizona. - PRIME FiBER is positioning the launch as part of a larger wholesale fiber buildout across the Phoenix metro area.

The details: - COS Wholesale Engine is a carrier-grade orchestration platform built for open-access and wholesale fiber environments. - The platform handles service qualification, order orchestration, appointment management and partner interoperability. - COS Systems says the platform uses standards-based APIs and operational automation to connect infrastructure operators and retail service providers. - PRIME FiBER will use the system to automate operational workflows and link wholesale infrastructure with retail service delivery processes. - Rob Johnson, PRIME FiBER’s CTO, said open access requires interoperability across multiple systems while still keeping the customer experience seamless. - Johnson said COS Wholesale Engine provides an operational foundation to support PRIME FiBER’s wholesale model and accelerate launches with major service providers like AT&T. - Sajan Parikh, CTO of COS Systems, said the company built COS Wholesale Engine for wholesale broadband ecosystems and to support PRIME FiBER’s scale.

Between the lines: - The partnership signals that software orchestration is becoming a core requirement in open-access broadband, not just a back-office add-on. - PRIME FiBER’s approach suggests it is betting on a wholesale model that depends on fast partner onboarding and repeatable launch processes. - AT&T’s role underscores how large retail providers can rely on third-party wholesale fiber platforms to extend reach into new markets.

What’s next: - The Sun City deployment is expected to support PRIME FiBER’s continuing expansion in underserved and high-growth markets. - PRIME FiBER and AT&T are likely to keep using the operational framework as the company grows its Arizona footprint. - COS Systems will continue positioning COS Wholesale Engine as infrastructure for broader wholesale broadband automation.

The bottom line: - PRIME FiBER is pairing fiber expansion with automation software to make wholesale launches faster and easier to manage.
