We use traffic management on our cable network to ensure the vast majority of our customers receive the high quality of service they expect. As part of the speed doubling programme, you'll enjoy faster speeds alongside increased peak time allowances enabling you to get even more out of your services. With significant additional investment being put into our network, we will be trialling a variety of different approaches to traffic management over the coming months to make the system more intelligent and flexible. To that end, we've started a STM trial in Preston and Selly Oak (Birmingham) this week that will last for the next 2 weeks.
Thanks
