What is Internet Leased Line
A dedicated business internet circuit designed to provide predictable bandwidth between a business site and the provider network.
For a growing business, internet quality affects far more than web browsing. A dedicated leased line gives the office a predictable connection for cloud applications, customer calls, VPN traffic, video meetings and large file transfers. The connection is provisioned for the customer rather than shared like a typical broadband service, so the commercial discussion should focus on committed bandwidth, SLA, latency, installation feasibility and support rather than only the advertised speed.
When evaluating providers, ask whether the proposed route has diverse last-mile options, what uptime and restoration commitments are included, and whether static IPs, managed routers, DDoS protection or backup links are available. A 100 Mbps connection with good routing and support can be more useful than a higher-speed circuit with poor last-mile resilience. Businesses with critical applications should also consider a second link from a different carrier or physical route.
BANTConfirm helps buyers structure the requirement around location, bandwidth, budget and timeline before requesting quotes. This makes vendor responses easier to compare and reduces the chance of choosing a plan that looks attractive on price but does not fit the operating environment.
A leased-line procurement brief should start with the business locations and the workloads that depend on connectivity. List the required bandwidth, number of users or sites, cloud applications, voice traffic, VPN use and any backup requirement. Then ask providers to confirm physical feasibility, last-mile ownership, installation assumptions, SLA metrics and restoration commitments. For critical offices, evaluate whether a second circuit can use a genuinely diverse route or carrier. Static IPs, managed routers, DDoS protection and monitoring should be treated as separate scope items unless explicitly included. Commercial comparison should show one-time installation, recurring rental, equipment and optional services separately. Buyers should also confirm the handoff, support escalation and process for service credits. This makes quotations comparable and avoids selecting a circuit based only on advertised Mbps. A structured requirement is especially useful when several locations need different bandwidth levels or when the business is moving workloads to cloud and needs predictable connectivity.
Key features and what to check before you buy
- Committed symmetric bandwidth and dedicated capacity.
- Last-mile feasibility and installation responsibility.
- SLA for uptime, latency, faults and restoration.
- Static IP, managed router, DDoS and backup options.
- Support escalation and monitoring.
- Installation, rental, taxes and contract terms.
For a useful quotation, include the quantity or capacity required, locations, current environment, integrations, users or concurrent demand where relevant, preferred timeline and any mandatory controls. Ask providers to separate one-time charges from recurring charges and usage-based charges. If a requirement depends on feasibility, coverage, regulatory approval or third-party platform availability, treat that as a validation item rather than assuming it is included.
