Line bonding has proved to be a "surprisingly popular" service, according to Be Broadband.
The firm explained there has been a high level of demand for line bonding, which enables end users to double their download speeds by using two lines at their local telephone exchange.
Be Broadband recently started selling line bonding services again, after it was forced to suspend activities in August due to the high number of orders being placed.
The firm explained that line bonding – which uses traditional ADSL broadband technology - is available to anyone with access to the nationwide Be network.
"The router does the hard work of merging the two connections, so you can plug it straight into your existing network at home or the office," the broadband provider said.
"A side benefit that's popular with businesses and people who run servers is that the two lines are independent, which can improve redundancy."
Be Broadband explained that the service is "not just for speed freaks" – it can be a good option for anyone who wants more speed but is limited by their distance from the exchange.
In order to take advantage of line bonding, users will need two telephone lines and will be required to pay an £85 connection fee and a £65 monthly subscription.
"Prices reflect the higher speeds and won't be everyone's cup of tea - but for people who need an unlimited, reliable, high speed connection recognise it's a good alternative to things like leased lines and SDSL," the firm said.
"Line bonding comes with the same unlimited, unthrottled experience that we provide across all our products."
Users can double their broadband speeds to a maximum of 44Mb using line bonding, and take advantage of 5Mb upload speeds.
