With two Calypso phones it becomes possible to serve two timeslots. Basically, second phone serves one TCH timeslot, but (if I am correct) PDCH has no fundamental differences from TCH, so its support could be implemented too.
After a quick look at OsmoTRX source code, I can assume, that the only difference between TCH channel combinations (I, II and III) and PDCH channel combination (XIII) is a fillerModulus value. Correct me if I am wrong.
Actually GPRS works fine with CalypsoBTS for years. Last time I've tested this was last year, and there was a small patch required in order to allow a PDCH in TS1 with the 'nanoBTS', but that's it.
I've put it here: https://steve-m.de/files/calypso_bts/
