Cole's one-year contract is worth $500,000, according to the Milwaukee Journal Sentinel. Arth reportedly signed a two-year contract.
Arth spent all or parts of the last three seasons with the Colts. Originally a nondrafted free agent, Arth last season was on the team's practice squad. He was an assistant to Peyton Manning the previous two seasons. As a senior in college, he earned first-team All-America honors at Division III John Carroll.
Cole, a 6-foot-2, 325-pound defensive tackle out of Iowa, played in all 16 games last year in his first full NFL season. Three of his four starts came in consecutive fashion from Dec. 11-25. He came away with a career-high 62 tackles (34 solo), including his career's initial two sacks, and batted down two passes.
A nondrafted free agent, Cole first entered the league with the Minnesota Vikings in 2003 and spent time with the Detroit Lions before making his NFL debut for the Packers in 2004.
