Wholesale Private Line circuits

Traditional SDH connectivity is still the preferred choice for some customers, which is why BT Private Line circuits remain a key part of our Wholesale portfolio, delivering high levels of security and resilience to multi-site organisations.

Many organisations still depend on large inventories of private line circuits to connect geographically dispersed sites. Consistent and reliable private lines serve their needs, and BT enables Service Providers to fulfil this requirement with Wholesale Private Line circuits.

Choosing BT as a single provider ensures global as well as local reach because of our partnerships with operators in more than 100 countries. And when your customer decides it’s time to upgrade, we can help them migrate to modern Ethernet and Optical services, seamlessly and cost-effectively.

Features and Benefits

Instant and adaptable – because private lines are permanently connected between sites, they can be accessed instantly without the delay of having to establish a connection. Lines will carry every type of traffic – voice, data, video and any combination.

Geographic reach – the wide coverage of BT’s all-Ireland network ensures strong local connectivity, matched by global coverage in more than 100 countries thanks to partnerships with local providers.

Reliable and secure – dedicated private lines are intrinsically secure. BT’s 24/7 monitoring will give your customers even more peace of mind and the confidence to use the lines for even the most sensitive of data.

Transparent costs – simple pricing structures include a one-off installation charge and a monthly fixed rental fee making it easy to control your costs. SLAs guarantee on-time delivery and high levels of service availability with credits offered if targets are missed.

Locally, our close-meshed Irish network provides wide coverage and enhanced technology for high transmission rates at low cost; internationally, global partnerships with carefully selected providers allow us to offer private line services in over 100 countries.

Every line is carefully managed to optimise performance and security. As well as proactive network monitoring by our state-of-the-art Network Management Centres, we provide on-site support and regular customer updates on fault resolution and security. If a connection fails, we immediately re-route the circuit to minimise disruption.
