Fast Turn-Up, Budget-Friendly, Great as a Secondary Path
Coax Cable Internet (DOCSIS) delivers broadband over hybrid fiber-coax (HFC) plant. It’s excellent for quick deployments and as a cost-effective underlay behind fiber—especially when paired with SD-WAN for resilience.
SolveForce provisions business-grade coax, integrates it with IPsec/SD-WAN, SASE/Zero Trust, and NOC telemetry, and documents everything with audit-grade evidence.
Where this fits in the portfolio:
🌐 Access → Connectivity • 💡 Prefer symmetric SLAs? → Fiber Internet
📡 Wireless options → Fixed Wireless • 📶 Mobile → Mobile Connectivity • 🛰️ Remote → Satellite Internet
🔀 Control → SD-WAN • 🔐 Edge → SASE / ZTNA
🎯 Outcomes (Why Coax with SolveForce)
- Fast time-to-service— ideal for new sites, swing space, and interim connectivity.
- Great secondary underlay— adds physical diversity behind fiber with solid bandwidth.
- Deterministic paths— IPsec/GRE to hub; SD-WAN steers by loss/latency/jitter.
- Evidence-first— turn-up baselines, SLO dashboards, and carrier tickets exported to SIEM/SOAR.
🧭 What You’re Getting (Plain-English)
- DOCSIS accessover HFC: provider manages the RF plant; you get an Ethernet handoff.
- Business coax tierswith higher upstream and static IP options (varies by market).
- Best-effort service(not DIA); pair with SD-WAN for application-level SLAs. → SD-WAN
📐 SLO Guardrails (Typical Business Coax Targets)
| Profile (market-dependent) | Down / Up (typical) | One-Way Latency | Jitter Target | Packet Loss (sustained) | Availability* |
|---|---|---|---|---|---|
| Mid-tier DOCSIS 3.1 | 100–600 / 10–35 Mb/s | 10–25 ms | ≤ 15% of latency | < 0.3% | 99.0–99.7% |
| High-tier DOCSIS 3.1 | 600–1200+ / 20–50+ Mb/s | 10–20 ms | ≤ 15% | < 0.3% | 99.0–99.7% |
| Sym-leaning (mid/high-split) | 300–1000 / 35–100 Mb/s | 8–20 ms | ≤ 15% | < 0.3% | 99.0–99.7% |
*Availability improves with dual underlays (e.g., fiber + coax) and SD-WAN brownout steering. Actual rates depend on node loading, plant quality, and split architecture.
🧰 Design Patterns (Pick Your Fit)
A) Dual-Path Branch (Fiber + Coax)
- Fiber = primary; coax = diverse secondary.
- SD-WAN steers per-app by loss/latency/jitter; IPsec to hub for predictable routing.
→ SD-WAN • Direct Connect
B) Interim / Quick Turn-Up
- Use coax to bring sites online while fiber is built; later keep coax as a backup underlay.
C) Tertiary Resilience (Fiber + LTE/5G + Coax)
- Triple-path for high availability: fiber primary, LEO/LTE secondary, coax tertiary.
🔒 Security & Zero-Trust (Built-In)
- Tunnels— IPsec/GRE from branch to hub/colo or cloud on-ramps for deterministic paths.
- Per-app access— ZTNA/SASE for users; no flat VPNs.
- Edge policy— deny by default; QoS classes; microsegmentation for OT zones.
- Secrets— pulled from vault; short-lived tokens; never in device configs.
→ ZTNA • SASE • Microsegmentation • Secrets Management
⚙️ Networking Notes (Reality Checklist)
- Static IP vs CGNAT— business coax often offers static public or private static IP; residential-grade plans may be CGNAT only.
- Modem/eMTA— we typically bridge to your firewall/SD-WAN CPE for policy control.
- DOCSIS splits— upstream capacity depends on plant split (mid/high-split markets have better uploads).
- Power— HFC relies on outside plant power; keep CPE on UPS and plan for node power events.
- MTU/MSS— set MSS for tunnels to avoid fragmentation; validate end-to-end path.
📊 Observability & NOC
- Telemetry we track: modem sync, power/SNR, correctable/uncorrectable codewords, retrains, throughput, latency/jitter/loss.
- SLO dashboards & alarms; carrier escalation runbooks; monthly SLA reviews.
→ Circuit Monitoring • NOC Services
💵 Commercials (No Surprises)
- Speed tier (down/up), static IP option, term (12/24/36 mo), and install type (standard vs special).
- Equipment: provider modem/eMTA + your firewall/SD-WAN CPE.
- Coax remains best-effort; for strict SLAs and symmetric bandwidth, see Fiber Internet.
🧪 Turn-Up & Acceptance
1) Pre-qual address and speed tier; confirm static IP need.
2) Install modem; bridge to FW/SD-WAN; bring up IPsec to hub.
3) Baseline throughput/latency/jitter + failover drills; archive RFC 2544/Y.1564-style results.
4) Monitor with NOC; thresholds/alerts; carrier escalation contacts.
Artifacts (photos, configs, tests) export to SIEM for audits. → SIEM / SOAR

Key terms in plain language
Open a term for a concise explanation of language used on this page.
Broadband
A general term for always-on, high-speed Internet access. Broadband can be delivered over fiber, cable, DSL, fixed wireless, cellular, or satellite networks.
Fiber Internet
Internet delivered through strands of glass using light. Fiber commonly supports high capacity, low latency, and strong upload performance, but availability must be confirmed for the exact address.
Bandwidth
The amount of data a connection can carry in a given time, usually measured in Mbps or Gbps. More bandwidth supports more users, devices, and simultaneous applications.
Latency
The time it takes data to travel between two points. Lower latency improves voice, video meetings, cloud applications, gaming, and other real-time services.
Service-Level Agreement (SLA)
A provider’s written commitment covering service targets such as availability, response time, repair time, and sometimes financial credits when commitments are missed.
Dedicated Internet Access (DIA)
A business-grade Internet connection with capacity dedicated to the customer rather than shared in the same way as typical consumer broadband. It often includes symmetrical speeds and an SLA.
SD-WAN
Software-defined wide area networking. It manages multiple connections and chooses paths based on application needs, performance, and policy to improve resilience and control.
VPN
A virtual private network creates an encrypted connection across another network, commonly allowing remote users or offices to access private resources securely.
