CTS - Computer Technology Specialists
Business Broadband, NBN and Enterprise Ethernet
CTS helps Melbourne businesses choose, configure, and manage the right broadband connection — from NBN Business for smaller offices to Enterprise Ethernet for high-availability environments where connectivity is as critical as any other IT system.

NBN Business broadband for Melbourne SMBs
NBN Business services offer speeds up to 1000/50 Mbps on the fastest Fibre to the Premises (FTTP) connections and include higher-priority traffic class (TC-4) for business plans, meaning business traffic is prioritised over consumer traffic during congestion. NBN Business plans also come with faster fault resolution SLAs than residential connections — typically a 24-hour restoration target rather than the 5-day residential standard. For Melbourne SMBs with 5-25 staff using Microsoft 365, Teams, cloud applications, and VoIP, an NBN Business plan on a 100/20 or 250/25 tier provides adequate bandwidth for most workloads.
Enterprise Ethernet — when to upgrade
Enterprise Ethernet (also called Business Fibre or Symmetric Ethernet) delivers dedicated fibre with symmetric speeds — the same bandwidth for uploads as downloads — and a 99.95%+ uptime SLA backed by financial credits. Unlike NBN (which is shared infrastructure), Enterprise Ethernet is dedicated to a single business. This matters for workloads that require consistent upload bandwidth — Teams Phone call quality, large cloud backup jobs, VoIP concurrent call capacity, and cloud-hosted server access all benefit from symmetric speeds. For Melbourne CBD offices with 25+ staff or mission-critical connectivity requirements, Enterprise Ethernet is the appropriate standard.
4G/5G failover for business continuity
Even Enterprise Ethernet connections experience outages — planned maintenance, third-party infrastructure damage, or carrier incidents can bring down a primary connection. A 4G or 5G failover connection provides an automatic failover path that activates within seconds of the primary link failing. CTS configures failover using SD-WAN or dual-WAN router configurations that detect primary link failure and route traffic through the mobile connection automatically. The failover connection is sized for essential traffic — voice calls, Microsoft 365 access, and critical cloud applications — rather than full bandwidth replacement.
Comparing NBN Business vs Enterprise Ethernet
- NBN Business — shared infrastructure, asymmetric speeds, 24-hour fault SLA, lower monthly cost, suitable for 5-25 users
- Enterprise Ethernet — dedicated fibre, symmetric speeds, 4-hour fault SLA with financial credits, higher monthly cost, appropriate for 25+ users or mission-critical connectivity
- NBN speed tiers range from 25/5 to 1000/50 Mbps depending on the technology type at the premises
- Enterprise Ethernet speeds start at 10 Mbps symmetric and scale to 10 Gbps or beyond for large installations
- Enterprise Ethernet contracts typically require 36-month commitments; NBN Business plans are available on 12 or 24-month terms
- Enterprise Ethernet is not available at all Melbourne addresses — availability depends on fibre infrastructure proximity
What CTS manages in your broadband setup
CTS manages broadband connectivity for managed IT clients as part of the overall IT environment. This includes carrier relationship management and escalation, router and firewall configuration to optimise traffic routing across primary and failover connections, QoS (Quality of Service) configuration to prioritise VoIP and Teams traffic, bandwidth monitoring to identify growth requirements before they become a constraint, and connectivity fault management — CTS lodges and manages fault tickets with carriers on the client's behalf.
Frequently asked questions
When should a Melbourne business upgrade from NBN to Enterprise Ethernet?
Enterprise Ethernet is appropriate when you have 25 or more staff with high connectivity dependency, require symmetric upload speeds for Teams Phone calls, large cloud backup jobs, or hosted server access, or need a higher SLA than NBN's 24-hour fault response. Enterprise Ethernet provides dedicated fibre with a 99.95%+ uptime SLA backed by financial credits — the right standard for Melbourne CBD offices and businesses where connectivity downtime directly affects revenue.
What is a 4G/5G broadband failover and does my Melbourne business need it?
A failover connection activates automatically within seconds when the primary broadband link fails, routing essential traffic — Microsoft 365, VoIP, critical cloud applications — through a mobile connection until the primary is restored. CTS configures failover on dual-WAN routers or SD-WAN devices for managed IT clients. Any Melbourne business where a connectivity outage causes material disruption to operations should have a failover connection in place.
