The crew of a B737-300 missed an altitude crossing restriction because the FMC was used to get ATIS while a descent to the restriction should have begun.

Narrative:
We were at cruise at fl 230 and told to cross a fix at fl 190. I was the pilot not flying so I read back the radio call and the pilot flying put 19;000' in the altitude window. We both verified it and I finished copying down the ATIS. When I was done; the pilot not flying immediately put the crossing restriction in the legs page and we saw we were close. We started down and got a frequency change. When we checked on with the center; the frequency was extremely congested and we weren't able to ask for relief on the altitude by the time we reached the fix. When we were finally able to check on; they asked if the previous controller had issued a crossing restriction and we said they had. If in an aircraft with one FMC; make sure to put in crossing restrictions before continuing on with copying down the ATIS.
