                         SPIRENT PLC AGREES TO ACQUIRE                         

              ANRITSU'S REMOTE SPECIAL SERVICES TEST PRODUCT LINE              

Spirent plc (LSE: SPT; NYSE: SPM), a leading international network technology
company, announced today that it has agreed to acquire certain assets of the
remote special services test product line of Anritsu Company US for a cash
consideration of $26 million (approximately £17.4 million). Following
completion of the acquisition, the remote special services test product line
will be integrated into the Service Assurance division of Spirent's
Communications group. The acquisition is expected to be immediately earnings
enhancing for Spirent.

The Anritsu remote special services test product line includes systems to
access, test and monitor the performance of networks for many of the world's
leading telecommunications service providers. Products being acquired by
Spirent include Anritsu's remote test probes and access units for HiCap (DS1
and DS3), Digital Data and voice frequency circuits, referred to as `special
services'. Anritsu's remote special services test systems currently monitor
some two million circuits for some 20 service providers located in eight
countries. For the year ended 31 March 2002, the product line being acquired
generated unaudited revenues of $21.5 million (approximately £14.4 million).

Nicholas Brookes, Chief Executive of Spirent, commented:

'We are firmly focused on growing the Spirent Communications service assurance
business. This acquisition further strengthens our award-winning broadband
product portfolio and opens opportunities to expand our customer base. Three of
the largest service providers in North America, Verizon, SBC and Qwest, have
made significant commitments to Spirent's service assurance solutions. This
acquisition will bring us additional installed base in these customers as well
as BellSouth, Korea Telecom and other important customers on which we can
build.'

Jim Schleckser, President of the Spirent Communications Service Assurance -
Broadband unit, commented:

'We already have a strong position in the special services remote testing
market. Special services, or private lines, are currently the primary broadband
access technology for business customers. We are committed to the market long
term and dedicated to helping our customers build the bridge from legacy
networks and operations support systems to next-generation technologies. We
look forward to fully supporting Anritsu's remote broadband test business
customers and their installed base.'

The acquisition is subject to certain terms and conditions and is expected to
complete next month. The cash consideration for the acquisition will be
financed out of Spirent's existing cash resources.
