BTW Network Changes – 3 month rolling plan
• BTW continually works to enhance its network, whilst minimising customer disruption. The four main drivers for change are:-
– Stability – to improve the reliability of the network. – Capacity – the need for additional capacity is driven by an increase in the number of broadband and ethernet
users on the 21C network (through migration from 20C and growth) and also by the ever-increasing bandwidth demands of those users.
– Resilience –to improve the resilience of the network , BTW is actively removing single points of failure from the network
– New Functionality – to meet the needs of the market BTW needs to enhance its network to deliver the services its customers require.
• This presentation outlines the key upgrade programmes, their drivers, customer impact and the number of upgrades per programme per week.
• BTW is keen to deliver all the required improvements as quickly as possible whilst actively managing the risk to customers. For this reason a range of run-rates against each programme has been outlined. The actual run-rates achieved will be determined by this ongoing live analysis of risk.
• Customer outage times for the PEWs normally start at 02:00 with the aim of completing customer impacting work by 06:00.
• Business as usual capacity upgrades and upgrades to resilient structures have not been listed here.
