2012-04-14femtobts: Use HW_FEMTOBTS instead of HW_VERSION_1 to select femtobtsHolger Hans Peter Freyther1-2/+2
Our header files use HW_FEMTOBTS guards to select the older femtobts design. Use the same macro in the bts code.
2012-04-05osmo-bts-sysmo: Add gsmtap for uplinkHarald Welte1-0/+30
2012-03-18osmo-bts-sysmo: Add GSMTAP support for transmit (DL) pathHarald Welte1-0/+66
there are VTY commands that can be used to filter which particular L1 sapis (channel types) should be sent in GSMTAP.
2012-03-17introduce a command that permits setting the clock source via vtyHarald Welte1-1/+6
the default source is the OCXO
2012-03-15we currently run the board alwasy in clock master modeHarald Welte1-0/+1
2012-03-15update to new "superfemto.h" header file namingHarald Welte1-20/+20
2012-03-07Introduce a HW_VERSION_1 #defineHarald Welte1-0/+11
This #define helps us to distinguish the subtle API differences between the earlier v1 (2011) hardware and the later v2 (2012) model.
2012-01-14sysmo: handle_ph_data_ind has paths rc is not initializedHolger Hans Peter Freyther1-1/+1
rc might not be initialized when going through the default statement but also hitting a break inside the switch case statement for GsmL1_Sapi_Sacch. l1_if.c:530:2: warning: Undefined or garbage value returned to caller return rc;
2011-10-12add VTY based way to set clock calibration of sysmobts L1Harald Welte1-1/+2
2011-09-09Inquire DSP/FPGA version at BTS boot and check band compatibilityHarald Welte1-0/+52
2011-09-07use osmo_ortp in POLLING mode instead of select loop integrationHarald Welte1-3/+22
This solves a lot of the problems we've been seeing in the context of large jitter (uRTP) or classic RTP with SID frames
2011-09-03Add new ORTP based libosmo-trau based voice supportHarald Welte1-27/+63
Using osmo-bts-sysmo and this code, it is now possible to do FR and AMR based voice calls on TCH/F. A lot of CPU is wasted in the conversion between the RTP formats and the L1 specific formats for the codec frames. All data needs to be shifted by four bits, and the order of bits needs to be reversed in every byte.
2011-07-24sysmobts: add a skeleton for codec frame processingHarald Welte1-5/+9
2011-07-07increae the RACH quality threshold to 5dB C/IHarald Welte1-1/+1
2011-07-05sysmbts L1 if: implement 'dead DSP L1 detection'Harald Welte1-0/+3
when we activate the SCH in the DSP, we start a 5-second timer. If we ever do not receive any MPH-TIME.ind primitives from L1 within that time frame, we stop the process (and will be re-spawned)
2011-07-05l1_if: send EMPTY-FRAME.req instead of fill frame on TCH/F + FACCHHarald Welte1-2/+18
2011-07-05increase RACH threshold to 1 dB C/IHarald Welte1-1/+1
2011-07-05add VTY commands for setting and showing DSP trace flagsHarald Welte1-0/+22
2011-07-02remove FIXME that has long been fixedHarald Welte1-1/+0
2011-07-01logging sanitization (use proper log levels, etc.)Harald Welte1-2/+2
2011-07-01fix BTS initialization orderHarald Welte1-3/+35
The sequence is as follows: 0) start osmo-bts 1) start connection attempts to BTS 2) issue L1-RESET.req 3) receive L1-RESET.conf 4) issue RF-ACTIVATE.req 5) receive RF-ACTIVATE.conf 6) receive attributes for TRX 7) receive opstart for TRX 8) issue MPH-INIT.req [...] The important point here is: We don't want the BSC to set TRX attributes or do TRX opstart before our RF related hardware is initialized.
2011-06-29sysmo-bts: Bring TCH (FACCH) into a working stateHarald Welte1-20/+58
2011-06-29Sysmocom l1if: Don't print hex-dumps of AGCH/SACCH messages anymoreHarald Welte1-4/+0
2011-06-29sysmocom L1: raise the threshold for ignored RACH burstsHarald Welte1-2/+2
the RACH burst detection in the physical layer is appranetly providing many false positives, and we need to raise the bar a bit in order to not allocate channels in a useless way...
2011-06-29implement baseic uplink measurement processing + reportingHarald Welte1-5/+30
* gather measurements from each PH-DATA.ind * check every TDMA frame about meas period expiration * compute averages after period expired * put MS DL MEAS REP into RSL MEAS RES messages, include UL meas bugs: * L3 INFO content seems to have some offset * is_sub is not set anywhere * measurement periods might have up/downlink offset
2011-06-27l1_if: We do not need to supply any SAPI on L1->L2 primitivesHarald Welte1-2/+1
2011-06-27re-work original osmo-bts with support for sysmocom femtobtsHarald Welte1-0/+622
This code re-works osmo-bts to add support for the upcoming sysmocom BTS. It also tries to add some level of abstraction between the generic part of a BTS (A-bis, RSL, OML, data structures, paging scheduling, BCCH/AGCH scheduling, etc.) and the actual hardware-specific bits. The hardware-specific bits are currently only implemented for the sysmocom femtobts, but should be (re-)added for osmocom-bb, as well as a virtual BTS for simulation purpose later. The sysmocom bts specific parts require hardware-specific header files which are (at least currently) not publicly distributed.
