Sonar Customer lights up MDUs with Sonar Professional Services
A custom Positron integration extends Sonar’s native Calix workflow to provision 24 subscribers from a single device — turning existing building wiring into gig‑speed access.
A Sonar customer based in the Southeastern United States with over 35,000 subscribers needed a way to deliver gig‑speed internet across entire apartment buildings using a single Positron device in the utility room. The blocker: Sonar’s native Calix integration is designed for one device per subscriber, not a single device mapped to many subscribers across 24 distinct ports.
Board‑approved rollout schedule demanded a fast, reliable solution
Existing Calix workflows could not specify a target port
Rewiring individual apartments with new fiber was cost‑prohibitive
The Solution
Port‑aware provisioning via Sonar Professional Services
Event‑driven middleware
Through event-driven middleware, Sonar listens for account activations, service changes, and item movement, then calls Calix to provision the correct Positron port.
Works with native Calix
The integration extends (doesn’t replace) existing Calix workflows, preserving the customer’s operational muscle memory.
Fast, low‑risk delivery
Delivered in ~4.5 weeks with production validation in the customer’s lab and field tests.
Clear naming & alerts
Items use a distinct Sonar_Positron_<id> convention with email alerts on key provisioning events.
24 subscribers, one device
The customer can light up entire buildings from a single Positron unit — with clean port mapping per apartment.
No new in‑unit wiring
Fiber enters at the demarc; existing coax/wiring does the rest.
Production‑proven
Validated in lab and field — with real‑world traffic flowing at gig speeds.
“We expected a partial demo. Instead, we got a full, working integration — and we haven’t been able to break it.”
