Yes, we hook up an external KPC-9612 TNC which has both 1200 and
9600 baud and then with the D700, we can actually monitor two
simultneous satelilte downlinks at the same time, and on one of
them, be receiving both 1200 or 9600 baud at the same time.

We used this on the Pcsats that downlink in 1200 and 9600 and
any combination on two separate channels.

But with the external TNC  you can only operate one band at a
time.  To operate a TNC cross band, you have top use only the
internal TNC.  Or use the extrnal TNC connected to the speaker
jack instead of the "data" jack.

Also, you could plug the DISPLAY HEAD from a D710 or stand-alone
RC-710 into that D700 data jack and have all APRS functions on
the two separate heads simultaneously.
