Great Britain's Fed Cup team are looking to end 19 years outside the World Group when they take on Sweden in Boras this weekend.
Not since 1993 have Britain been among the top 16 nations in women's tennis, but victory in an even-looking tie at Borashallen would earn them a place in World Group II.
Judy Murray took over as captain in December and guided her team out of Europe/Africa Zone Group I at the first attempt in Israel in February, with Britain winning three round-robin matches and then a play-off against Austria.
Elena Baltacha and Anne Keothavong took the two singles spots in all of those matches and rose to the challenge, with Baltacha emerging unbeaten, while Laura Robson and Heather Watson won their three doubles clashes.
The players fill the same roles in Sweden, but this time the format is the same as Davis Cup, with four singles rubbers instead of two and one doubles, although the tie is played over two days rather than three.
After finally helping Britain climb out of Zone I with victory in her 46th Fed Cup rubber, Baltacha is relishing the chance to take another step forward.
The 28-year-old wrote in her BBC Sport column: "Having done that massive slog, being here feels like the reward.
"This is the first time since 1993 that Great Britain's women have got this close to being among the top 16 nations in the world, so, don't get me wrong, we're not satisfied at all.
"It's just funny because every other Fed Cup tie I've played in my career has been as part of a massive group of other teams and it took me a while to cotton on to the fact that there is only us and the Swedes here.
"I've also never had to play more than one tie in a year before, because we have never been able to get past that first week before - so this all feels quite new and special."
Sweden just have the edge in the rankings, with Sofia Arvidsson and Johanna Larsson ranked 54th and 71st compared to Baltacha and Keothavong at 63 and 79, but Britain have greater strength in depth.
Teenagers Robson and Watson are both ranked just outside the top 100 and are able singles deputies, while Sweden are very dependent on Arvidsson and Larsson.
Baltacha will open proceedings on Saturday at 1pm UK time against Larsson before Keothavong faces Arvidsson, with the reverse singles and then doubles taking place on Sunday.
Robson hailed the impact made by Murray and believes Britain's team spirit can be a crucial factor.
"Judy was fantastic in Israel and it's been good here so far," Robson told the Daily Mail.
"She is very good at technical analysis and we've done a lot of that. While there is a lot of hard work she realises it's important to have a bit of fun and she's great at building a good atmosphere."
Robson, meanwhile, has revealed she is looking for a new coach after ending an interim arrangement with Luke Milligan.
In the meantime she will continue to work with Sven Groeneveld through the adidas player development programme, which has given her the chance to practise with former world number one Caroline Wozniacki.
Robson said: "I played some great matches while working with Luke but now I need to look at the long term
"I've known Sven since I was 11 and he has a lot of knowledge about my game. It has been fantastic practising with Caroline. She hardly ever misses a ball and there is so much I can learn from her. Apart from anything else she is a very nice person."
