                                STRATEGIC REVIEW


London, UK - 5 November 2007: Spirent Communications plc ("Spirent" or "the
Company") (LSE: SPT), a leading communications technology company, is announcing
today the results of the second phase of the Group Review.

As stated in the interim results announcement on 9 August 2007 the aims of the
Strategic Review were to address the Company's business portfolio and product
development priorities, as well as further cost containment opportunities and
the structure of the balance sheet.

Overview

The restructuring of the Company aims to target Spirent to areas of strategic
advantage in desirable market segments in order to deliver growth in excess of
the industry average.  Incremental cost savings of £7.3 million have been
identified, principally to the benefit of 2008, bringing the total savings to
£28.3 million.  These have been achieved with minimal effect on sales and
product development, as demonstrated by current trading and planned product
introductions for 2008, and at no increase in exceptional costs.

Business portfolio
     
•    Focus on developing the core Performance Analysis business, operating
     at 11 per cent return on sales.

•    During the third quarter 2007, growth in Spirent TestCenter(TM)business
     exceeded the decline in legacy business for the first time.

•    Service Assurance operating at 11 per cent return on sales with a
     stable outlook for 2008.

•    Systems operating at 12 per cent return on sales in a stable long term
     market.

Product development
     
•    Build on the exceptional product breadth of our core business Performance 
     Analysis through greater engineering efficiency.

•    Enhance development of Spirent TestCenter.

•    Migrate to a higher software component in the business.
     
•    Pursue integration synergies and wireless market opportunities.

Cost containment
     
•    Further incremental savings of £7.3 million identified, equivalent to 0.
     8 pence earnings per share.

•    Incremental savings achieved with no increase in exceptional costs.

•    Trading performance in the third quarter demonstrates that the cost
     improvements have been achieved with minimal effect.

Balance sheet structure
     
•    From 1 January 2007 to the end of September, £21 million has been
     utilised for share repurchase.

•    Targeting a total return through share repurchases of £65 million by
     the next AGM.

•    Strong cash generation for the nine months ended September 2007 - net
     operating cash inflow of £26 million.

Corporate Governance
     
•    Board composition is now compliant, as is each Board Committee.

Edward Bramson, Chairman, commented:

"The business has become more predictable and the strong cash flow performance
supports continued future financial flexibility.  Planned product introductions
in desirable market segments offer encouraging prospects for Spirent to deliver
medium term growth."
