25Gbps CTX Technical Brief
See KB24091807 for a complete list of CTX services.
Our 10G Carrier Tail (CTX) provides a fixed, uncontended point-to-point Ethernet connection with no PON infrastructure.
Our service offers flexible options to suit your connectivity needs, scalable as standard to 100Gbps with 99.99% availability. For more information, please refer to CTX Service Level Agreement (KB24091815).
Diversity
We provide fully diverse routes across Central London, with multiple Points of Presence (PoPs) and separate paths to customer sites for enhanced resilience. Custom route maps can be supplied on request for your approval.
Our extensive coverage across London allows us to effectively avoid pinch points—areas where network paths converge and create potential single points of failure. We can also establish new intakes into buildings to ensure a completely independent and diverse connection path.
Rapid installation
Rapid installation is available on most of our fibre services. Details can be found in KB24091818.
Installation and equipment
We provide a demarcation device per line on site, meaning for all diverse lines, all equipment is fully independent.
