Hi I think just one person can respond your question in the world just Andreas I hope Andreas too reads this text because he does not respond to my letter. It will Certainly possible if you know l1l[3].tx_mask=???? in this site http://www.mail-archive.com/baseband-devel@lists.osmocom.org/msg00098.html sylvan Is told that is possible In theory, sure. But as I said, no idea if the code supports it. Also as I said above one phone can't receive consecutive timeslots so it would be R_R_R_R_ at best I hope Andreas too read this text and respond please?

Question 1: If you are asking if a osmocom-TRX can increase its capacity to multiple handsets by extending the timeslot. I dont think that it is possible (I may be wrong), the handsets are already working beyond their intended capacity in osmocom-TRX.
Question 2: Every incomming TDMA frame generates an interrupt function in sync.c called l1_sync(void). The dsp_api structure is used to communicate with dsp from layer1. If the DSP has encountered an error it puts the error code in dsp_api.ndb->d_error_status. Currenlty dsp errors are printed to the users but generally ignored look at the following code-sample from inside of l1_sync:
if (dsp_api.ndb->d_error_status) { printf("DSP Error Status: %u\n", dsp_api.ndb->d_error_status); dsp_api.ndb->d_error_status = 0; }
This means that regardless of what d_error_status it will be set to 0 and the program will continue as normal, you may consider this message a debug warning.
The file src/target/firmware/include/calypso/dsp_api.h details the different error codes available and their meaning.
