LONDON, March 17 (Reuters) - Bankers working on Vodafone's $10 billion deal to buy Spain's Ono could pocket up to$62 million in advisory fees, according to an industry estimate,the latest windfall for dealmakers in the technology, media andtelecom (TMT) sectors.

Vodafone Group Plc said on Tuesday it has agreed tobuy Spain's largest cable operator Ono, as the British grouprebuilds its European operations with a broadband offering.

Vodafone adviser Morgan Stanley and Robertson RobeyAssociates, who assisted the company's board, will share fees ofbetween $22 and $27 million, Freeman Consulting, which tracksbankers' fees, estimated.

Deutsche Bank, who acted as lead adviser for Onoshareholders, will receive the lion's share of a $28 to $35million fee pool. The remainder will be split with co-advisersBank of America Merrill Lynch, UBS andJPMorgan.

TMT has been a particular bright spot for investment banksso far this year, thanks to several high-profile deals includingComcast's $45.2 billion takeover of Time Warner Cable and Facebook's $19 billion acquisition ofmessaging service WhatsApp. .

Year-to-date, global M&A activity in TMT is up 186 percentto $266.9 billion based on 1,424 deals, compared with $93.2billion over 1,589 deals a year earlier, Thomson Reuters datashows.

Total worldwide M&A activity so far in 2014 is up 48 percentt $627 billion, according to the data.

Fees earned by TMT bankers have risen accordingly, jumping18 percent on a year ago to $893.9 million, Freeman estimated.By contrast, fees earned by bankers across M&A are broadly flatyear-on-year at $4.3 billion.

Thomson Reuters data ranks Morgan Stanley as the topinvestment bank in TMT M&A, having worked on deals worth $113billion, including the pending Comcast and Facebook deals.

Goldman Sachs, an adviser to both Vivendi and Numericable, which are now in exclusive talks overtelecoms unit SFR, takes second place.

Freeman estimates that the nine banks that worked withNumericable could earn fees of between $43 million and $52million. Those advising Vivendi, including Lazard andBNP Paribas, could share between $51 million and $59million.

Goldman, the world's top deal adviser for nine of the past10 years, has missed out on a number of 2014's largest mergers.
