DvSum gives your NOC an impact-ranked, RCA-backed workqueue — built from NXT telemetry, subscriber context, and HFC domain intelligence. Your analysts stop chasing signals and start resolving problems.
The Problem
The Alarm Storm
The node with 40 enterprise subscribers on SLA gets ranked below the node with 400 residential subscribers — because the signal looks worse. Your best engineer corrects it. The night shift doesn't. Two to three hours per analyst per day, manually sorting a queue that should already be sorted.
The Reactive Trap
Operators don't stay reactive by choice. They stay reactive because the subscriber impact signal needed to justify proactive dispatch doesn't exist. So you wait for the alarm — and by then, the subscriber has already called.
"Every tool you have tells you what alarmed. None of them tell you what's about to — or what you already learned about it last month."
What Your NOC Lives With
Alarm Storm
Your queue ranks by signal physics. Not subscriber impact. Not SLA exposure. Not business vs. residential mix. The experienced analyst knows which alarm matters. The rest of the shift works the loudest one.
Silent Failures
The most dangerous nodes in your plant are stable-but-marginal, degrading and recovering, never crossing threshold — until the hot Sunday when the cascade collapses. Current tools tell you what's bad. None tell you what's fragile.
Manual RCA
Upstream SNR degradation: ingress, amplifier failure, or congestion? Answering that question today means pulling RF data, checking topology, cross-referencing FEC rates — and calling on a decade of plant knowledge. There is no tool that says "ingress, confidence 87%, check the drop cluster in segment 3."
Knowledge Trap
Tech dispatches to Node 47. Finds a loose F-connector. Closes the ticket: "replaced connector." Three weeks later — same alarm, same node, new analyst, diagnosis from scratch. Workforce knowledge doesn't compound; it evaporates when engineers leave.
How DvSum Solves It
Prioritize
Subscriber impact + business vs. residential mix + SLA exposure — not signal levels. Your 40-subscriber enterprise node ranks above 400 residential if it's at SLA risk. P0/P1 working view. P2 trend-flagged so aging problems surface before they escalate.
Detect
Flapping modem patterns, thermal drift signatures, marginal-but-stable nodes flagged before they cross the threshold. Long-horizon trend tracking surfaces the amp that recovers every night but is degrading week-over-week — what operators call "fragile, not bad."
Reason
Connectivity / Congestion / Performance analyzed in parallel. Output: "Ingress — second cascade segment — confidence 87% — check F-connectors at tap cluster." Not a list of alarms. An answer — with the evidence chain behind it.
Learn
Two learning signals: (1) Analyst approves or overrides every RCA — that signal updates knowledge cards so the next similar event is diagnosed more accurately. (2) Post-repair telemetry — before/after signal comparison confirms whether the fix actually worked, independent of ticket closure.
The Act Layer
Act means the system recommends the right action to the right person at the right moment — with full context. You define how much of the loop to automate. Today at most operators: analyst-assisted. The system surfaces a recommendation; the analyst validates it in one click. Every recommended action is logged with its evidence chain — you can audit why the system made that recommendation at any point.
Auto-Fire
Action executes directly
Confidence above 0.75. Action executes directly — your team configured this boundary. Fully logged with evidence chain.
Confirm
One-click analyst approval
Confidence 0.50–0.75. Recommendation surfaced for one-click approval. Full context visible before the analyst acts.
Review / Block
Flagged for investigation
Lower confidence or new node type. Flagged for analyst investigation. System continues learning from the outcome.
The automation boundary is yours to define. It expands as your team builds confidence in the system.

In Production
All metrics from Liberty Latin America production deployment. NTF truck roll figure applies to NTF-specific dispatches only. RCA accuracy measured at week 6 of production; degrades on new or unseen node types. Active pilot: Rogers Canada (UC2A) — available as NXT integration reference.
Integrations
DvSum connects to the NMS you already run via its data catalog layer — NXT/Aurora, Calix, VIAVI, and other leading platforms. A lightweight gateway deploys inside your network perimeter. Your data never leaves.
DvSum understands the signal — not just the alert. Full integration specs in the data sheet.
We run a 2-week Data Audit on your NXT telemetry — no live operations, no workflow change. At the end, you see your actual node prioritization, RCA patterns, and silent failure risk. It either confirms you have a gap or proves you don't. Either way, you know.
