After being held high with a late descent and speed restr clearance, flight crew could make the altitude restr, but were still too fast. Because the ATC frequency was congested, the flight crew was unable to notify the controller of their speed immediately, but when finally contacting ATC, they acknowledged and told them to slow and descend further.

Narrative:
ZHU vectors and altitude restr placed us high to make navasota 125 degree radial 7 mi fix at 10000 ft and 250 KTS. Altitude restr of 10000 ft was made, however, we planned to tell houston approach we would be fast. The radio was very busy and when we finally contacted approach control we informed the controller as to our dilemma. The controller acknowledged and we were told to expedite our speed reduction and a descent to 6000 ft. No problems arose from this however, an earlier handoff from the center to approach would probably have taken care of the expeditious relay of pertinent information.

Title: AFTER BEING HELD HIGH WITH A LATE DSCNT AND SPD RESTR CLRNC, FLC COULD MAKE THE ALT RESTR, BUT WERE STILL TOO FAST. BECAUSE THE ATC FREQ WAS CONGESTED, THE FLC WAS UNABLE TO NOTIFY THE CTLR OF THEIR SPD IMMEDIATELY, BUT WHEN FINALLY CONTACTING ATC, THEY ACKNOWLEDGED AND TOLD THEM TO SLOW AND DSND FURTHER.
Narrative: ZHU VECTORS AND ALT RESTR PLACED US HIGH TO MAKE NAVASOTA 125 DEG RADIAL 7 MI FIX AT 10000 FT AND 250 KTS. ALT RESTR OF 10000 FT WAS MADE, HOWEVER, WE PLANNED TO TELL HOUSTON APCH WE WOULD BE FAST. THE RADIO WAS VERY BUSY AND WHEN WE FINALLY CONTACTED APCH CTL WE INFORMED THE CTLR AS TO OUR DILEMMA. THE CTLR ACKNOWLEDGED AND WE WERE TOLD TO EXPEDITE OUR SPD REDUCTION AND A DSCNT TO 6000 FT. NO PROBS AROSE FROM THIS HOWEVER, AN EARLIER HDOF FROM THE CTR TO APCH WOULD PROBABLY HAVE TAKEN CARE OF THE EXPEDITIOUS RELAY OF PERTINENT INFO.
