Johannesburg - The South African Fed Cup team was drawn in Pool A alongside hosts Estonia in their Euro/Africa Zone Group Two four-day event starting on Wednesday.
Also in South Africa's pool were Bosnia-Herzegovina and Egypt.
South Africa's team captain Earl Grainger said his charges would have to perform at their best to be competitive .
"The teams are extremely tough and two teams, Estonia and Slovenia, are a bit stronger than us but that is only on paper," Grainger said from Estonia on Tuesday.
"This group is really tough."
Their first tie was against Egypt at the Tere Tennis Centre in Tallinn on Wednesday.
With Chani Scheepers in their line-up at 83rd in the WTA rankings, the South Africans had at their disposal the second highest-ranked player at the event.
"Chani has been really fantastic since her arrival in Estonia and we had a great training session together with her fellow teammates. The girls have loved having her around and she brings positive professionalism to the team," Grainger said.
The eight nations contesting the Euro/Africa Zone Group Two event were Bosnia-Herzegovina, Egypt, Estonia, Finland, Ireland, Luxembourg, Slovenia and South Africa, all bidding for promotion to the Euro/Africa Zone Group One in 2016.
South African team: Chani Scheepers, Chanel Simmonds, Ilze Hattingh, Michelle Sammons, Earl Grainger (captain).
