+* priority
+three sources of audio transmission:
+- crypto-data high priority
+- tones high priority (also high)
+- remote-data low priority
+
+* elapsed
+a variable that temporarily shows the number of samples elapsed since last transmission process.
+p_m_last_tv_* is used to store that last timestamp. this is used to calculate the time elapsed.
+
+* load
+a variable that is increased whenever data is transmitted.
+it is decreased while time elapses. it stores the number of samples that
+are currently loaded to dsp module.
+since clock in dsp module is the same clock for user space process, these
+times have no skew.
+
+* levels
+there are two levels:
+ISDN_LOAD will give the load that have to be kept in dsp.
+ISDN_MAXLOAD will give the maximum load before dropping.
+
+* procedure for low priority data
+see txfromup() for procedure
+in short: remote data is ignored during high priority tones
+
+* procedure for high priority data
+whenever load is below ISDN_LOAD, load is filled up to ISDN_LOAD
+if no more data is available, load becomes empty again.
