Bonded FTTC combines 2+ FTTC lines for speeds up to 320 Mbps. 50–70% savings vs. leased lines. Benefits: failover, fast setup, VoIP. Best for high-speed without critical uptime needs.
What is bonded FTTC and when should your business use it? Bonded FTTC combines 2+ Fibre to Cabinet lines into single logical connection delivering aggregated speeds (up to 320 Mbps download, 60 Mbps upload). Works by splitting data streams across multiple FTTC lines, then recombining at receiving end. Similar concept to bonded DSL but faster speeds. Benefits: 50–70% cost savings vs. leased lines, comparable speeds, automatic failover resilience (if one line fails, remaining lines continue service), fast 10-day installation (vs. 65–75 days for leased lines), suitable for VoIP/video conferencing. NOT uncontended service—speeds variable. Best for businesses needing high speeds without mission-critical uptime guarantees or budget for leased lines. Realistic speeds: 200–300 Mbps combined practical maximum.
Bonded FTTC addresses connectivity challenge: FTTC availability limited to certain areas, but single FTTC lines often insufficient for growing bandwidth demands. Rather than expensive leased lines, bonding multiple FTTC connections delivers comparable speeds cost-effectively.
This guide explains bonded FTTC mechanics, realistic speed expectations, cost comparison with alternatives, and when bonded FTTC delivers genuine value.
Bonded FTTC splits outbound data into multiple streams distributed across FTTC lines simultaneously. Receiving end recombines streams into single high-speed connection.
Example: Video streaming normally sent as single data stream through one FTTC line. With bonded FTTC, video split into multiple fragments sent simultaneously through two FTTC lines. Receiving end reassembles fragments instantly appearing as continuous stream.
Distribution happens at packet level (individual data packets). Each packet routed through FTTC line based on intelligent load-balancing algorithm. Packets arrive at destination in potentially different order, reassembled correctly by receiving bonding device.
Bonding device sits on-site (customer premises) between connection point and firewall. Presents single RJ45 interface to network—network devices see single connection, not multiple lines. Bonding device handles all splitting/recombining complexity transparently.
Service provider maintains matching bonding device at data centre. This device recombines packet streams, handles failover logic, manages monitoring.
Bonded FTTC marketing often cites 320 Mbps download, 60 Mbps upload. This represents absolute peak—multiple optimal FTTC lines bonded perfectly.
Realistic bonded FTTC speeds: 200–300 Mbps combined (accounting for bonding overhead, line quality variation, network conditions).
Scenario 1: Two 50 Mbps FTTC lines bonded = approximately 95–100 Mbps combined
Scenario 2: Four 75 Mbps FTTC lines bonded = approximately 280–300 Mbps combined
Key point: Bonded speeds faster than single FTTC line, but NOT guaranteed at peak rates due to broadband variability.
Single 100 Mbps leased line: £300–500/month. Bonded FTTC achieving similar speeds: £150–250/month. 50–70% cost savings.
Business impact: Organizations on tight budgets can access high-speed connectivity affordable.
Bonded FTTC speeds (200–300 Mbps) match single dedicated leased lines at fraction of cost. Organizations prioritizing speed over guaranteed SLA benefit significantly.
If one FTTC line fails, bonding device automatically reroutes traffic through remaining lines. Service continues without interruption (speed reduced proportionally).
Example: Four lines bonded, one fails = service continues at approximately 75% speed automatically.
Bonded FTTC typical installation: 10 days. Compare alternatives:
Business benefit: Rapid deployment for organizations needing speed quickly.
Bonded FTTC optimized for low-latency applications. VoIP requires latency below 150 ms—carrier networks typically deliver below 30 ms. Video conferencing, streaming function well on bonded FTTC.
Bonded FTTC appears as single transparent connection to firewall. Minor firewall configuration changes needed—no major rewiring required.
Broadband (even bonded) remains shared/contended service. Peak times may see slower speeds. Not suitable for organizations requiring guaranteed bandwidth.
Speeds fluctuate based on network conditions, line quality, time of day. Organizations requiring guaranteed speeds need leased lines.
Bonded FTTC only possible where FTTC available. Rural areas without FTTC infrastructure cannot use bonded FTTC.
Unlike leased lines (often 99.9% SLA with financial penalties), bonded FTTC provides no formal service level guarantees. Failover automatic but no compensation for downtime.
Single FTTC: Lower cost, simpler, but lower speeds (typically 30–75 Mbps)
Bonded FTTC: Higher cost, more complex, but higher speeds (200–300 Mbps)
Choose bonded FTTC if: Speed important, FTTC lines available, budget permits bonding cost
Leased line: Guaranteed speeds, formal SLA, higher cost (£300–500+/month), 65–75 day installation
Bonded FTTC: Variable speeds, no SLA, lower cost (£150–250/month), 10 day installation
Choose leased line if: Guaranteed uptime critical, mission-critical operations, can justify premium cost
Choose bonded FTTC if: Speed important but uptime not mission-critical, budget-conscious, fast deployment needed
Standard broadband: Cheapest (£30–80/month), slowest (10–30 Mbps)
Bonded FTTC: Mid-range cost (£150–250/month), high speeds (200–300 Mbps)
Choose bonded FTTC if: Standard broadband insufficient speed but leased line unaffordable
A: Yes, minor configuration changes needed (router rules, security policies). IT team can typically implement in less than one hour.
A: Service providers typically include bonding device in service cost. No separate hardware purchase required.
A: Yes, designed to support VPNs. Appears as single transparent connection—VPN sees single link, not multiple underlying lines. Single line failure doesn't disconnect VPN.
A: Failover automatic, transparent to users. Speed reduces proportionally (four lines, one fails = ~25% speed reduction). No service interruption.
A: Typical 10 days from order to live connection.
Start by confirming FTTC availability at your location. If FTTP available, single FTTP connection often superior to bonded FTTC.
Next, assess speed requirements. If current broadband insufficient but mission-critical uptime not paramount, bonded FTTC worth evaluating.
Then, request quotes from bonded FTTC providers. Compare costs with single leased line. Calculate ROI difference.
Finally, discuss failover/VPN compatibility with provider. Confirm hardware included, setup timeframe, ongoing support.
