Narrative

AFTER LNDG ON RWY 7R WE WERE TOLD TO HOLD SHORT OF RWY 7L AT F13. (ANOTHER COMPANY ACFT WAS HOLDING SHORT OF RWY 7L AT F11 AND ANOTHER CARRIER WAS HOLDING SHORT AT F12). TWR CLRED THE OTHER 2 ACFT TO CROSS RWY 7L AND THEN CLRED US TO CROSS AND TO CONTACT GND CTL. AS WE WERE XING RWY 7L MY FO CONTACTED GND WITH THE PHRASE; 'COMPANY FLT NUMBER CLRED RWY 7L AT THE END FOR SPOT X.' GND TOLD US TO 'HOLD SHORT OF THE NEXT INTXN; AND GIVE WAY TO THE AIRBUS.' THIS HAD US HOLDING SHORT OF TXWY E WITH OUR ACFT STILL ON THE RWY SIDE OF THE HOLD SHORT LINE. FREQ CONGESTION WAS SUCH THAT WE WERE UNABLE TO QUERY GND CTL IF THEY WANTED US TO TECHNICALLY BE ACROSS THE HOLD SHORT LINE. QUICKLY THE AIRBUS HAD ADVANCED TO A POINT THAT PREVENTED US FROM MOVING FORWARD. ANOTHER COMPANY ACFT DID DEPART RWY 7R WHILE WE WERE ACROSS THE HOLD SHORT LINE; BUT WITH A 10000+ FT RWY; WAS OF NO CONSEQUENCE TO OUR SAFETY. GND HAD APPARENTLY CONFUSED OUR ACFT WITH THE COMPANY ACFT THAT HAD CLRED AT F11 WHO WAS IN A POS AFTER CLRING TO GIVE WAY TO THE AIRBUS ON TXWY E. I BELIEVE THAT GND CTL WAS MOMENTARILY OVERWHELMED WITH 3 ACFT XING A RWY ALMOST SIMULTANEOUSLY AND; PERHAPS DID NOT HAVE AN OPTIMAL VISUAL PERSPECTIVE OF THE SIT.
