Narrative:
We received a TCASII alert and then a TCASII command to descend at 2000 FPM. At FL226 I saw an air carrier widebody transport at 1 O'clock. We held at FL226 until clear of the widebody transport then climbed back to FL230. ZJX was told of the alert. Center asked if we had to descend and I said yes. We then climbed back to FL230. We first saw the target 3 mi on TCASII as 1400 ft (descending). That is the last time we keyed on TCASII target altitude. I was visual and the PF was concentrating on TCASII rate commands after that.

Narrative: WE RECEIVED A TCASII ALERT AND THEN A TCASII COMMAND TO DSND AT 2000 FPM. AT FL226 I SAW AN ACR WDB AT 1 O'CLOCK. WE HELD AT FL226 UNTIL CLR OF THE WDB THEN CLBED BACK TO FL230. ZJX WAS TOLD OF THE ALERT. CTR ASKED IF WE HAD TO DSND AND I SAID YES. WE THEN CLBED BACK TO FL230. WE FIRST SAW THE TARGET 3 MI ON TCASII AS 1400 FT (DSNDING). THAT IS THE LAST TIME WE KEYED ON TCASII TARGET ALT. I WAS VISUAL AND THE PF WAS CONCENTRATING ON TCASII RATE COMMANDS AFTER THAT.
