  • BT are currently offering 100Mbps using 1Gbps circuit bandwidth at £282 using Netify discounts.

BT Authorised Partners are an alternative route into BT vs Local Business and Corporate. In this article, we've included some examples of where we've transacted BTNet orders with specific offers from the Partner Channel. All quotations are available with or without a managed Cisco Meraki Wireless router together with a number of failover options including Broadband, 4G and Ethernet over FTTC depending on availability. We are able to specifically analyse options for your business to understand whether certain failover options may not be available.

Where maximum uptime is required, resilient access products allow us to design Ethernet capability with no single point of failure, subject to survey. And, we'll also provide the option to include Security and Cloud access with hosted voice packages or SIP where required.

Real world results

Client - Woodrush School

Industry -  Education

Their problem was - Woodrush were looking for 100Mbps leased line connectivity for their School campus.

Results - Faye Parker ordered BT Business leased line connectivity via BT Partner Sales with an additional first year discount. We worked with Faye to set expectations across installation and have recently added 100 Cloud Voice licences to their account.

What is the typical SLA for BT leased line services?

  • 4 hour support response time and 5-hour target fix.
  • Flex bandwidth quickly up to the the 100Mbps or 1Gbps Ethernet limit.
  • Delivery SLA: Beyond 7 days of CDD (Committed Delivery Date).
  • BT Leased lines provide 100% availability, reduction of rental charges if an outage occurs
  • Core network guarantees a latency of 20ms or less between core nodes.
  • Transatlantic leased line latency is guaranteed at 95ms of less between transit hubs.
  • All managed hardware should covered for 4-hour change where required. (based on the typical Cisco fix time)

Obtaining the latest BTNet leased line pricing is a great way to set budgets and to make sure your business is obtaining the best deals. 

  • Infrastructure both here in the UK is key but also across the globe for International based business.
  • Ethernet services offer 1:1 guaranteed bandwidth - understanding coverage is key to unlocking performance.
  • You can flex your bandwidth speeds, why not take a 100Mbps Ethernet circuit and opt for a lower bandwidth tier to reduce leased line costs. Upgrades can be completed anywhere from a few hours.
  • Connection availability is assured via a service level agreements, but there are other failover options.
  • BT prevent downloading of illegal content, and there are options to further protect against malicious attacks.
  • Managed services with Cisco Meraki or Juniper edge.
  • BT leased line services offer accreditation including both BSI 7799 / ISO 17799.
  • Public allocated IP addressing is provided.
  • Performance data is available to provide network statistics.

What are the resiliency and diversity options to improve BTNet SLA uptime?

Adding resilience to your BT leased line requires the addition of a diverse secondary circuit, RA02 Secure Plus. We will primarily design a solution which avoids any single point of failure (subject to survey). The success of any resilient and diverse solution surrounds the ability to connect into diverse building entry points, dual routers and dual tail circuits routed to separate exchanges.

Again, this is a real plus point regarding the discussion of network coverage since larger network providers can provision/route your traffic into diverse points within the network. With managed services, two managed routers are deployed configured as an HSRP pair. If one managed route fails, the failover would automatically re-route your Internet traffic.

As you would expect when connecting a second circuit, the overall costs will increase.

Services are also available with load balancing - the traffic is shared across two physical access which, again, may be diversely routed. The second circuit could be a lower bandwidth than the primary circuit depending on the traffic profile. With leased line bandwidth connection speeds available from 10MBits Ethernet through to 10Gbps within hosting sites, there's a little risk of congestion. Available managed (with router) or unmanaged.

BT leased lines offer a 1:1 performance guarantee, uncontended to ensure applications and data perform with a consistent level of speed and uptime. These features provide a competitive edge to your business. As an example, 35% of UK broadband consumers use BT's Internet services with peering agreements which mean 75% of users connecting to the Internet are only a hop away.

Flexing of bandwidth is easy: you're able to flex within 72 hours, so you only pay for what you need. With circuits typically based on 100MB Ethernet, you'll get plenty of bandwidth to avoid congestion.

BT Ethernet circuits are supported 24/7/365 with a 4 hour response time and 5 hour fix. The only exception if copper-based Ethernet First Mile (EFM) where the support fix time is typically around 7 hours.

In the corporate environment, it is important to protect users and your web presence. We ask about security to prevent illegal downloading of content - including  optional services which safeguard your web presence against attacks.

BT Leased Line BGP Multihoming

A further more complex design is available called BGP multihomed architecture. This is where two ISPs are used to provide diversity and resiliency. Customers purchase their own AS (Autonomous System) number and essentially become part of the Internet.

Leased line IP Addressing and DNS (Domain Registration System)

  • BT include a set of IP addressing and DNS management
  • The DNS element covers where the ISP points your traffic for web, email and other hosts. 
  • For example, if you host your own web or email server, DNS resolves the hostname to the IP address - e.g. Wikipedia to an IP address.

Firewall Security, DDoS, IP Addressing and DNS

All public Internet services require Firewall security to protect your userbase from external threats. With the addition of Cisco Meraki, BT (as an example) now offer the security licence to negate the need for an additional Firewall. In addition to general security, how your business intends to use the leased line from the perspective of applications must also be considered. If, for example, voice (VoIP) is to be used, the users traffic is typically segregated.

In the corporate environment, it is important to protect users and your web presence. Leased line services offer security to prevent illegal downloading of content. Selected ISP capabilities also offer optional services which safeguard your web presence against attacks.

The Internet Watch Foundations managed blacklist to prevent users from downloading illegal content. Providers also proactively monitor and protect the core network against denial of service attacks. There is also security accredited to BSI 7799 / ISO 17799 with optional distributed denial of service protection. Essentially, the service mitigates against traffic DDoS attacks, DoS floods, Protocol misuse, works and behaviour anomaly based attacks. If you're unsure about these terms, we'll explain over coffee.

DDOS (Distributed Denial of Service) is an additional option available to clients.

IP Addressing is available - both IPv4 and IPv6 - but all applications must be justified to RIPE. In other words, let us know as soon as possible the amount of hosts on your network requiring a static IP address.

With regards to DNS, the typical email system is based on the Simple Mail Transfer Protocol(SMTP). SMTP allows the transmission of messages from one server to another.

Multiple mail servers may be used (if you have your own mail server) an SMTP outgoing mail service and a 2nd preference incoming mail service. This is based on standard SMTP protocols.

The services supported by the Mail platform are:

  • Outgoing Mail (SMTP Relay) – customer can configure email server to send via the ISP mail server
  • Incoming Mail (2nd preference Mx) - Provides a back-up mail service to the customer’s primary mail server. The customer would configure their DNS settings so that in the event their primary mail server is down their mail gets sent to the Incoming Mail servers. Servers hold the mail for 3 days and will attempt to re-deliver this mail to the end customer’s primary mail servers when they become available. This is a backup mail service.
  • Access to the SMTP outgoing mail relay service is controlled by adding the Customer’s domain name to an access list. The customer must have a matching forward (A record) and Reverse DNS12 entry that should be provided at time of order.
  • The Incoming and outgoing mail relays both use the Spamhaus blacklist and will not relay or accept mail for IPs on this list. Customers managing their own mail servers must ensure they are NOT configured to allow open mail relay. Failure to enforce this could lead to the ISP blocking all customers mail as open relays are used for SPAM.

What else is there to know?

  • Since your traffic is best served when sent over a single provider (rather than effectively hopping from provider to provider) certain networks have a significant advantage vs. most of the competition.
  • And perhaps this is the key critical area to be aware of since smaller providers may be offering Internet access out of a single data centre using wholesale providers such as Open Reach and Virgin to connect your business.
