Culmen ISP Suite — Professional Licence

The full platform for operators up to 2,000 subscribers, with multi-uplink failover and content filtering included.

Everything in Starter, plus

• Automatic failover engine — health monitoring across multiple upstream carriers, fast to fail away from a broken link and deliberate to fail back
• Multi-uplink routing — policy routing across several transit providers, removing the single point of failure
• Quota-aware load balancing — a line that spends its daily allowance hands its share to the healthiest line until the window closes
• Content filtering — five-layer filtering with per-tier policy
• Scheduled bandwidth windows — different rate profiles by time of day, including unmetered free windows, applied automatically
• Priority support — direct access during deployment

Deployment

Installed on your hardware and configured to your topology. Includes data migration from your existing billing system where one exists.

Licence terms

Perpetual licence. One-time payment, no per-subscriber fees. Includes installation, configuration and 12 months of updates.

Compare: subscription platforms at this subscriber count typically run $500–$1,200 per month, indefinitely.

Sizing

At 2,000 subscribers the software is not the ceiling — your backhaul is. Plan for a 10G or 20G core uplink, SFP+ on the router, and PON splits calculated against real peak demand rather than nominal line rate. On microwave backhaul, expect to need multiple radios. Sizing guidance is included with the licence.
