Why Careful Contract Review Matters

Essential Questions to Ask Before Signing a Leased Line Contract

| Are there any Excess Construction Charges (ECCs)? | Unplanned installation costs can add thousands to your bill. |
| What is the installation lead time? | Planning ahead avoids disruption to operations. |
| What uptime guarantee is provided? | SLAs should promise at least 99.99% uptime. |
| What is the fix time for faults? | Critical faults should be resolved within 4 hours. |
| Is the bandwidth guaranteed and symmetrical? | Essential for cloud applications and VoIP systems. |
| What happens if I need to upgrade speed? | Check upgrade flexibility and any associated costs. |
| What are the early termination fees? | Understand penalties if your business relocates or closes. |
| Is a backup connection included? | Secondary links or 4G failover improve resilience. |
| What are the terms for price increases? | Ensure costs are fixed or understand annual rises. |
