Open Access vs Closed Access Fiber Networks: What Operators Need to Know
How the two models differ, and what open access changes for provisioning, billing and support.
AEX is the wholesale operations platform for open access networks, connecting every ISP to your network through a single interface.

AEX was built for open access operators and has run that way for more than a decade: a wholesale catalog your ISPs build their retail products against, per-ISP ordering and provisioning, an ISP-facing API and portal, and billing that runs both ways. Adding a retailer is a configuration against a standing interface, not an integration project on both sides.
If you run a closed network today and may open it later, you can do that on the same platform. Opening a network means changing configuration and commercial terms, not moving to a new system. It still takes real work across networking, billing, and product management, and we will plan it with you in detail.

More than 100 ISPs sell over networks that run on AEX for OSS/BSS.
No. Closed access is the same platform with one retail brand configured, and plenty of operators run it that way. The point is that you are not choosing a system that forecloses the other model, in either direction.
It’s a configuration and commercial exercise rather than a replatform, but it isn’t nothing. It touches three areas: how subscriber sessions are handed off on the network, how wholesale and retail billing split, and how your product catalog is restructured so ISPs can build against it. We’d work through all three with your team before quoting a timeline.
It depends far more on your commercial process than on ours. On the platform side, an ISP needs an entity, a catalog relationship, portal and API credentials, and VLAN assignment on the network. Our role is to make sure none of that is bespoke.
No. It never required retail open access, and the narrower middle-mile interconnection and wholesale requirement in the original NOFO was removed in June 2025 under the Benefit of the Bargain restructuring. Where public money does favor open access, it’s at the state level, New York’s ConnectALL municipal program being the clearest current example.
Both. ISPs work in their own view of the platform for products, coverage, customers, services, and work orders, and integrate to the AEX ISP API for the same functions. Smaller retailers tend to live in the portal; larger ones integrate.
Yes. The model is set per network, so an operator running closed access in one market and open access in another runs both from one system, with the rules for each applied automatically.
