Great Britain's Fed Cup captain Anne Keothavong says they can emulate the men's Davis Cup team and "put women's tennis on the map in this country".
They begin their campaign in Estonia on Wednesday in the Europe/Africa zone.
Johanna Konta, the first British woman to reach the world's top 10 in 32 years, joins Heather Watson, Laura Robson and Jocelyn Rae in the GB squad.
"Hopefully Jo's success and the way she goes about it will inspire the other girls," said Keothavong, 33.
British number one Konta, 25, reached the quarter-finals of the Australian Open before a nine-match winning streak - which included victory at the Sydney International - was ended by Serena Williams.
