After MDANO DFW Center cleared us to descend to FL330; then pilot's discretion to 240. I asked if we were cleared on the DEBBB1 arrival was told the next controller would assign the arrival. Next controller assigned VIA DEBBB1 arrival approaching BELFR. Began reviewing arrival points and was interrupted with radio call and checklist. About 2-3 miles prior to LETNN we noticed wrong altitudes for fix. First Officer (FO) increased descent with speed brakes; and I tried to call ATC for relief. Was unable to get a word in with Center until LETNN fix. Controller replied with something like 'request should have been earlier'. Was handled to approach control and given vectors to DEBBB intersection. Upon further review somehow JOVEM arrival was selected.    On STAR arrivals where same points are used and altitudes differ; point names should be changed or not identical. This would help aircrews notice discrepancies sooner on STAR arrivals. As pilots; altitudes on every arrival where fixes are the same or similar altitude vigilance will have to be monitored more closely; especially when STAR arrivals are received late.
During descent from FL330 to FL240 on the DEBBB1 RNAV arrival into DFW; MDANO transition; and after vectors and new speed restrictions were issued; we discovered the JOVEM1 RNAV was in the FMC. We asked for altitude relief at LETNN intersection; but frequency congestion was problematic. All other speed/altitude constraints were complied with pertaining to the DEBBB1 RNAV arrival; and landed without any further problems. I was in the [relief pilot] position.Quicker notification of which specific arrival we were to fly; as the first controller said the next controller would issue the appropriate arrival. Closer review of which arrival was in the FMC; which arrival was issued and being flown.
B777 flight crew reports being cleared for the DEBBB One (RNAV) Arrival to DFW. During descent it is noticed that the JOVEM One (RNAV) Arrival is loaded in the FMC which uses many of the same waypoints with different crossing restrictions. LETNN is crossed 3;000 feet high.
