Bryan Biedenkapp ed4c7aca49 fix issue with RemoteCommand not properly connecting the UDP socket; fix SNDCP_CH_ANN not properly computing Rx frequency; implement TIA-102.AABF-2015 LC_CONV_FALLBACK specification;
4 years ago
Bryan Biedenkapp 4239d21a2b initial experimental support for DFSI communication via DVM modem serial interface (DFSI support is disabled from compilation entirely by default, the -DENABLE_DFSI_SUPPORT compiler directive is required to enable it);

Bryan Biedenkapp 28c0d383d5 bump copyright dates;

Bryan Biedenkapp 71c18d9aa9 cleanup implementation;

Bryan Biedenkapp 842c17c985 more very very experimental PDU AMBT support;

Bryan Biedenkapp 8bd0a0cbbc more very very experiemental PDU AMBT support;

Bryan Biedenkapp 2d99f7f48f add very very experimental support to process PDU MBTs into TSBKs;

Bryan Biedenkapp cf364aa2c5 fix issue with P25T VOC networked traffic where the P25T VOC channel would not process network voice frames (this is really a partial fix, there is still room for more improvement);

Bryan Biedenkapp dd5bfa235b continue implementing DFSI; remove some header information (it was included incorrectly some cases);
4 years ago
Bryan Biedenkapp 16a9e59f44 add capability to disable unit-to-unit availability check (U2U calls are still acting strangely though); ACK a EMERG_ALRM_REQ (but do nothing else, this is by design); properly ignore a TSBK_IOSP_TELE_INT_ANS, we don't support PTSN connections (and probably won't ever);
4 years ago
Bryan Biedenkapp d588982b72 implement an internal DVM MFId so we can abuse TSDUs to transmit call termination across the network with ease; properly implement GRP_VCH_GRANT_UPD;
4 years ago
Bryan Biedenkapp 94213364fa add option to disable TSDU MBF transmission; recorrect generated slot status bits during TSDU transmission;
4 years ago
Bryan Biedenkapp ab56ce8a3a cleanup copy assignment implementation for LC and TSBK;
5 years ago
Bryan Biedenkapp 525ffd9471 refactor P25 LC; refactor DMR CSBK; better handle scenario where P25 may start without having received a HDU, in this case we will transmit without HDU which would be interpreted by SUs as a late entry condition (better helps encryption sync in some cases);

Bryan Biedenkapp 09df9a0241 file commenting cleanup;
5 years ago
Bryan Biedenkapp a66f91fe2f minor fixes and cleanups; allow transmitted service class properly reflect registration and composite classes based on configured options;
5 years ago
Bryan Biedenkapp e71e946990 support location registration;
5 years ago
Bryan Biedenkapp ef453a4f73 remove old TDULC Channel Grant logic (I don't even remember why this was here); move TDU preamble before voice call; correct Modem debug messages appearing as regular log messages;
5 years ago
Bryan Biedenkapp aa1a3d5ed8 enhance available options for P25 control data (enable/disable broadcast, enable/disable dedicated); enhance availablt options for RCON for enabling/disabling P25 CC dedicated and broadcast, as well as some remote debug enable/disable commands;
5 years ago
Bryan Biedenkapp 3375748224 fix incorrect handling of GRP_VH_REQ during a network voice call;
5 years ago
Bryan Biedenkapp 28bb91fbd2 fix issue where erroneous CALL_TERM would be transmitted; support SCCB_EXP for when there is more then one CC at a site;
5 years ago
Bryan Biedenkapp 4b3e8de18f add support to selectively do a hex dump of the TSBK, TDULC or DMR CSBK bytes for encode/decode; add appropriate P25 PDU response packet; correct CRC-9 table and implementation (although I believe its still wrong); add support to adjust engineering parameters for symbol levels; add support to selectively disable P25 ACK responses for some TSBKs;
5 years ago
Bryan Biedenkapp 8feecf49ec correct RF talkgroup hang timer (allows the local RF to steer the talkgroup); fix labeling for the preamble and DMR Rx Delay; correct TDU preamble before voice transmission in P25;
6 years ago
Bryan Biedenkapp 95364cbcf1 implement support for auto-affiliating units who can't affiliate in "enhanced" mode; better handle generating MBF CC data;
