What is a leased line?

A leased line is a permanent, dedicated high performance telecommunications network connection which can carry voice, data and Internet traffic via a copper or fibre optic connection between a customer site and a Zen Point of Presence (POP). Leased lines are also sometimes referred to as a T1 connection/ T1 line, or an E1 connection/E1 line.

Why would I need a leased line?

Leased lines are used by businesses that need high speed reliable Internet access 24 hours a day, seven days a week giving greater peace of mind. They offer dedicated, uncontended bandwidth ensuring that the maximum line speed is always available when required.

What speeds are available with a Leased Line from Zen?

Our leased lines are available in three products: Fibre Ethernet, EFM and EoFTTC. Fibre Ethernet is available from 1Mbps up to 1Gbps, EFM from 1Mbps to 35Mbps, and EoFTTC from 1Mbps to 20Mbps.

We have fibre at our premises; can this be used for the leased line service?

All quotations assume existing fibre is present and available for use, however, a site survey will still have to be carried out to ascertain whether the correct fibre is present and available for use. This can only be determined following order placement.

Can the leased line service be upgraded?

Yes, but there are some restrictions that need to be considered however. When upgrading from an older services, a new circuit and CPE may be required. All Ethernet circuits can be upgraded up to the maximum speed of the circuit (10Mbps, 100Mbps, or 1Gbps) subject to increased annual rental charges.

What equipment is needed to connect to the leased line service?

All our Leased Lines and Ethernet services are provided with a fully managed Cisco Router suitable for your service.

How secure is the leased line service from Zen?

A leased line is inherently secure in its own right because it operates as a point to point service. However, if a connection is provided to the Internet additional security services will need to be implemented such as firewalls. We provide a full range of managed security products, more details can be found in the security section.

Can I use my existing firewall?

Yes. Any firewall can be installed behind the CPE to protect the customer network from security breaches; however, Zen will only support devices that form part of a contracted managed security solution. For a full Unified Threat Management solution more details can be found in the security section.

Is it a totally managed solution from Zen?

Yes, we offer a fully managed leased line service. This incorporates management of the CPE and monitoring of the leased line circuit. However, we also offer an unmanaged service (wires only) for some customers wishing to source and manage their own hardware.

What Service Level Agreement (SLA) is available on the leased line service?

Our Leased Line and Ethernet customers are covered by a 100% SLA. If your service is unavailable at any stage, you are entitled to service credits as compensation.

What level of support is available?

The service is fully supported 24/7 by our BSU team and Network Operations Centre. Any faults reported by customers will receive a response within 1 hour.

Can we save money with a leased line/Ethernet line from Zen?

You can actually save a considerable amount of money through vast improvements in performance, reliability and uptime, thereby improving organisational efficiency. This can apply from small companies with few users up to large companies with thousands of users.
