(Adds revenue details, share price, background)

MEXICO CITY, Feb 7 (Reuters) - Mexico's dominant fixed-line telephone operator Telmex posted an 11 percent fall in fourth quarter net profit for its local operations, which are being separated from its international operations.

Telmex (TMX.N) (TELMEXL.MX), controlled by billionaire tycoon Carlos Slim, said on Thursday its October-December net was 6.664 billion pesos ($610 million), or 0.34 pesos per share.

For its international operations, which Telmex is spinning off from its local unit, Telmex reported a fourth quarter net profit of 1.986 billion pesos against a loss of 638 million pesos.

Telmex said revenue from its local operations dropped 2.4 percent to 31.830 billion pesos.

Core earnings before interest, taxes, depreciation and amortization, or EBITDA, dropped 9.3 percent to 14.154 billion pesos.

Shares of Telmex rose 1.29 percent on Thursday to 19.66 pesos ahead of the results release. Its New York-traded stock moved up 1.68 percent to $36.40.

Telmex is spinning off of its fast-growing international operations from the stagnant parent firm and will call the new company Telmex Internacional. Plans are to list the company on Mexican and U.S. stock markets.

The international company will include fixed-line operators, television cable companies and Internet service providers in Brazil, Argentina, Chile, Colombia, Ecuador and Peru.

Telmex, a former state-owned monopoly, dominates the fixed-line and long-distance market in Mexico but has come under pressure in its local markets from increased competition and shrinking profit margins.
