Internet service provider Andrews & Arnold (AAISP) has decided to provide its customers with broadband access to the Be network as well as BT's.
Previously, the internet wholesaler had offered the majority of its customers broadband access via BT 21CN and 20CN lines.
However, following a string of problems with those services, the provider has signed a new deal to allowing it to use cheaper unbundled connections on Be Broadband and O2's Be network instead.
AAISP said on its blog: "This will allow us to provide an alternative to BT routed broadband lines where everything from the exchange equipment right back to the link in to us is separate from BT.
It warned that the Be network would not be available from all exchanges, but predicted that around 80 per cent of its customers would be able to make the switch.
"We plan to launch a range of new packages to use this service shortly including bonding and fall-over high availability dual line broadband solutions using BT and BE lines together."
The ISP specialises in high-reliability business broadband subscriptions and provides a number of multi-line packages in order to cut down on the risk of failure causing an outage.
