The company said it will axe the 1,200 positions, 1,100 of which are full-time, from the Global Markets Group (GMG) in order to save money.
The cuts will start to be implemented over the next few weeks, although the company does not yet know what the costs savings from the cuts will be, said Nicholas Sweers, director of public relations for Sprint E-Solutions and Network Services.
Sprint also announced it will discontinue its Digital Subscriber Line (DSL) high-speed Internet access platform in some cities where Sprint has found another way to deliver the same service, or where it is too expensive to continue the service.
A timetable for decommissioning the service has not been determined yet.
Sprint FastConnect, the DSL service offered in 18 US states by Sprint's Local Telecommunications Division, will not be affected, the company said.
DSL will be offered to GMG customers through Sprint's local and long-distance divisions.
Sprint "will make every effort" to refer customers who lose their high-speed access to another provider if Sprint does not resume service in their area, he said.
Sprint GMG will also help reorganise the company's E-Solutions Web hosting, consulting, marketing and sales into the Sprint Business division, while moving the customer and technical service operations from E-Solutions to Network Services, the company said.
