Ireland are undefeated in their Euro 2016 qualifying campaign to date, having beaten Georgia and Gibraltar and claiming a creditable away draw at world champions Germany.
O'Neill's men next face a visit to Scotland on November 14, before hosting the US in a friendly in Dublin on the following Monday, and the coach is keen to see his players maintain their momentum.
"I am looking forward to assembling the squad for the last time this year in preparation for our final games of 2014," he said. "I am absolutely delighted with the courage and determination we showed in our last two qualifiers, and hope we can continue this run next month against Scotland and the USA.”
Hull City's Brian Lenihan is the only uncapped player on O'Neill's bumper list, although the defender has been named in a preliminary squad before.
Record cap-holder and goalscorer Robbie Keane is named among the strikers, while O'Neill has given himself five goalkeepers to choose from.
