This article is designed to guide customers who wish to use their own router, firewall, or switch with our Leased Line service. It outlines the available handover types, the technical requirements for each, and key considerations for successful setup.
While we provide the necessary IP details and handover specifications, configuration of customer-owned equipment is the your responsibility. This guide ensures you have the right hardware, understand the IP addressing model, and are prepared to connect confidently to our network.
💡Please refer to your handover documentation or ask your order owner for which type of connection we have installed.
Copper (RJ45 Ethernet)
Description:
Delivered via a standard RJ45 Ethernet port
Uses twisted pair copper cable
Most common for short-distance handovers
What you need:
A router, firewall, or switch with a Gigabit Ethernet RJ45 port
No SFP module required
A standard Cat5e or Cat6 Ethernet cable
Typical Use Case:
Office environments with short cable runs
Plug-and-play setup with minimal configuration
Fibre – Single Mode (LC Connector)
Description:
Delivered via Single Mode fibre optic cable
Uses LC connector
Supports long-distance transmission
Narrow laser beam for high precision
What you need:
A router, firewall, or switch with an SFP port
A Single Mode SFP module
A Single Mode fibre patch cable with LC connectors
Typical Use Case:
Large campuses, data centres, or long-haul links
High-speed backbone connections
Fibre – Multi Mode (LC Connector)
Description:
Delivered via Multi Mode fibre optic cable
Also uses LC connector
Supports short-distance transmission
Uses broader LED or VCSEL light source
What you need:
A router, firewall, or switch with an SFP port
A Multi Mode SFP module
A Multi Mode fibre patch cable

Support Boundaries
We’re happy to provide the technical details you need to connect your equipment—such as IP addressing and handover type—but we do not offer support for configuring customer-owned routers, firewalls, or switches. Customers are responsible for setting up and managing their own devices.
💡Need help with configuration? In exceptional cases, support may be available at an additional cost. Please contact your account manager to discuss options.
IP Addressing & Configuration
Our standard setup includes:
Point-to-Point (P2P) IP Address: Assigned to the interface connecting to our Network Termination Equipment (NTE)
Customer LAN IP Range: Routed over the P2P link for internal use
Customer Responsibilities:
Configure your device with the provided P2P IP on the WAN interface
Set up routing or NAT to utilise your LAN IP range
💡If you require a different IP setup (e.g., bridged mode, static routing), please inform us during provisioning
Speed & Hardware Compatibility
Leased lines are available in various bearer speeds (e.g., 100Mbps, 1Gbps, 10Gbps).
To ensure optimal performance:
Check your device specs: Your router, firewall, or switch must support the speed of your leased line
Verify port types: Ensure your equipment has the correct interface (RJ45 or SFP) and compatible modules
Avoid bottlenecks: Older or underpowered devices may struggle with high-throughput connections
