Specific wireline assets to be gained from Alcatel-Lucent would be the core and edge routers sold to service providers, of which Alcatel-Lucent is the No. 4 and No. 2 player in the industry, respectively.To read this article in full or to leave a comment, please click here

Nokia/Alcatel-Lucent just as John Chambers predicted
