"Ventilation? Sure, yeah. Uh, hold on..." The screen of your cell goes to the blue prints of the building, and zooms up to 40th floor with a flourish. Then, green lines spring over the blue background. "There's the utility lines and stuff. I think the nearest useful shaft is next to the first door after the elevator, one your left--hold on, got another call."
"Yeah. Just, like, go to the 52nd floor, and press the hold door button a bunch of times. One min, call waiting."
"Yeah, after first door on your left as you exit the elevator. Crawl strait for about 35 meters, then turn right and go for another 5. There's an exit right there, onto the hallway with White's door just a bit a way. There aren't any shafts that lead strait into the room."
"Just hand White your cell, he'll pull a disappearing act, and make sure you have it with you when you exit the Matrix. See, the legit system is represented by the phone lines, and our pirate signals are represented by sell phone transmissions. So get White into the cell, and get the cell out."
