Reference excerpt

The National Network Management Centre is the main national network operations centre of BT Group, situated in Shropshire.

History BT moved to the countryside site in the 1980s. The NMC is also known as the Customer Experience and Management Centre, the International Network Management Centre (INMC), or the National Control Centre (NCC). The BT Global Media Network delivers television content around the world. BT Retail split into BT Consumer and BT Business. The transformation of BT's network to becoming digital began in 1985, and finished in July 1990. BT's Worldwide Network Management Centre at Oswestry opened on 5 September 1990, at a cost of £4m. The site appeared on the BBC Two documentary Genius of Invention.

Structure It is situated on the A495, within a few hundred yards of the road's western terminus at the roundabout with the A5, in the west of the parish of Whittington. The site has a staff of around 440. Jamie Ford, the former chief executive of Plusnet, runs BT IT Services. There were originally two buildings - A and B. Building C was built to link these together and forms the hexagonal reception building. Building D was built to be the new Network Management Centre, which has now been superseded by the New Wave Building.

Display screen The site has a large display screen, built by Synelec (bought by Planar Systems), made from 140 composite screens. The screen is ten feet high, and seventy feet wide.

Function The site is the home of the UK's speaking clock. BT IT Services, headquartered at Barlborough in Derbyshire on the A616, have a main operation in the building. It monitors network traffic on BT's network across the UK, including 0800, 0845 and 999 numbers. It monitors televotes provide by RIDE (Recorded Information Distribution Equipment). RIDE is accessed via the SOAP protocol. At peak periods it implements call gapping load control. BT Wholesale controls its traffic from the site. Every two minutes the site contacts around 700 of BT's telephone exchanges to find out how busy they are. 80% of BT's network consists of optical fibre.

They can apply routing changes to the network if an issue arises such as a major loss of power to an area or an emergency number being announced following a disaster or restrict calls to that number. They also monitor the main news channels to get early indication of a major incident. In addition calls being routed via the UK BT network from foreign telecom groups (i.e. USA to Far East) are monitored and controlled here.

Worked examples

Example 1 — a first encounter with National Network Management Centre

Start with the simplest possible case. Write down what National Network Management Centre claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to National Network Management Centre before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about National Network Management Centre ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of National Network Management Centre

In research: National Network Management Centre appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses National Network Management Centre in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: National Network Management Centre is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s establishments in the United Kingdom, BT Group buildings and structures, Buildings and structures in Shropshire, so understanding it makes those chapters shorter.
In everyday life: Look for National Network Management Centre outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
