BT is to close the trial network it set up for its 21CN (21st Century Network) linking exchanges in central London, Woolwich and Cambridge. The network has carried over 160 million calls, and made communications history by carrying the first phone calls over a totally IP, next generation network. The testing involved 600 BT employees and the equipment handled over 500,000 calls per day.
Wick, in South Wales, saw the first live customers moved onto BT's 21CN in November last year, and BT are looking to complete the migration of 350,000 customers in the Cardiff area this year.
This follows news yesterday of Paul Reynolds, Chief Executive of BT Wholesale is leaving BT to become CEO of Telecom New Zealand. Paul lead the development of BT's 21CN, placing it where it is today.
Further details on the trial 21CN closure are available on the BT Media centre.
