NEW YORK (CNNMoney.com) -- Ex-WorldCom CEO Bernard Ebbers reported to a federal correctional institution in Oakdale, Louisiana Tuesday to begin his 25-year sentence for his role in an $11 billion accounting fraud.

The Oakdale, Louisiana Federal Correctional Institution is in central Louisiana, 35 miles south of Alexandria and 58 miles north of Lake Charles, according to the Federal Bureau of Prisons.

Oakdale FCI has a population of 1,172 male inmates and 485 staff.

Medium-security prisons have "strengthened perimeters" according to the Federal Bureau of Prisons website, which often include double fences with electronic detection systems, cell-style housing, "a wide variety of work and treatment programs."

Jobs can include cutting grass, raking leaves; doing plumbing or painting; working in food services; cleaning bathrooms, showers, and buffing floors, according to Mike Truman, Spokesman for the Federal Bureau of Prisons.

Truman said medium-security prisons also provide educational programs such as adult continuing education, GED high school equivalency certificate, and subjects like English for speakers of other languages, personal growth and life skills.

Such prisons have both legal and leisure libraries for inmates.

A typical day would start at 6 a.m. with work starting 1 and a half hours later.

Work usually ends at 3:35 p.m.

At 4 p.m. comes "count time" when each inmate, unless he is assigned to the food service area, must be by their bunk, Truman said.

Mail call follows count time which is then followed by dinner, served in staggered shifts.

After that, inmates can typically walk in the recreation yard around the track or go to the chapel or the library, Truman said.

Depending on the institution, the day most likely finishes around 9 p.m. when inmates are required to be back in their bunks with lights out.

Ebbers will be required to wear a khaki uniform. An on-facility commissary allows inmates to buy personal items such as soap, toothpaste, or toothbrushes.

Ebbers was convicted by a jury in March 2005 of nine counts of conspiracy, securities fraud and other crimes that led to the phone company's July 2002 bankruptcy.

Ebbers transformed WorldCom into a telecommunications powerhouse through a string of takeovers. He was known as a grandfatherly CEO who preferred cowboy boots to suits, but he also has been described as an exacting, cost-obsessed boss.

WorldCom emerged from bankruptcy as MCI Inc., which was later acquired by Verizon Communications Inc (up $0.46 to $37.96, Charts). Ebbers agreed last year to forfeit almost all of his personal wealth in a settlement with WorldCom investors.
