 How to comply with Section 13 of the AGPLv3 license.
 
 The recommended method for compliance with Section 13 of the AGPLv3 license is
-to deliver a text message to each handset that attaches to the cellular
-network which uses OsmoTRX.  At a minimum, that text message should include the string
-"OsmoTRX AGPLv3" and a URL that can be used to access the OsmoBTS source code.  This

+network.  At a minimum, that text message should include the string "OpenBTS
+AGPLv3" and a URL that can be used to access the OpenBTS source code.  This
 message need not be delivered to handsets that are denied registration with the
 network, since those handsets have been denied service.
+
+In OpenBTS 2.6, such text messages can be delivered with the "Welcome Message"
+feature.  See the OpenBTS.config.example file for more information on the use of
+this feature for AGPLv3 compliance.

- * rate_ctr API uses several osmocom select loop features, and as a result,
- * calls to it must be done through the main thread (the one running the osmocom
- * loop in osmo-trx).
- * Since read/write from/to SDR is done in separate threads (even read and write
- * each use a different thread), we must use some sort of message passing system
- * between main thread feeding rate_ctr structures and the Rx/Tx threads
- * generating the events.
- * The idea is that upon read/write issues, lower layers (SDR APIs) provide us with
- * underrun/overrun/droppedPackets information, and in that case we pass that up
- * the stack through signal <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> with signal_cb
- * being a pointer to a "struct device_counters" structure, which contains
- * device (implementation agnostic) statful counters for different kind of
- * statistics.
- * That signal is processed here in device_sig_cb, where a copy of the "struct
- * device_counters" structure is held and the main thread is instructed through
- * a timerfd to update rate_ctr APIs against this copy. All this is done inside
- * a mutex to avoid different race conditons (between Rx andTx threads, and
- * between Rx/Tx and main thread). For the same reason, callers of signal
- * <SS_DEVICE,S_DEVICE_COUNTER_CHANGE> (device_sig_cb), that is Rx/Tx threads,
- * must do so with PTHREAD_CANCEL_DISABLE, in order to avoid possible deadlocks
- * in case the main thread decides to cancel other threads due to a shutdown

+This is the interface to the transcevier.
+
+Each TRX Manager UDP socket interface represents a single ARFCN.
+Each of these per-ARFCN interfaces is a pair of UDP sockets, one for control and one for data.
+Give a base port B (5700), the master clock interface is at port P=B.
+The TRX-side control interface for C(N) is on  port P=B+2N+1 and the data interface is on an odd numbered port P=B+2N+2.
+The corresponding core-side interface for every socket is at P+100.
+For any given build, the number of ARFCN interfaces can be fixed.
+
+
+
+Indications on the Master Clock Interface
+
+The master clock interface is output only (from the radio).
+Messages are "indications".
+
+CLOCK gives the current value of the transceiver clock to be used by the core.
+This message is sent whenever a trasmission packet arrives that is too late or too early.  The clock value is NOT the current transceiver time.  It is a time setting the the core should use to give better packet arrival times.
+IND CLOCK <totalFrames>
+
+
+
+Commands on the Per-ARFCN Control Interface
+
+The per-ARFCN control interface uses a command-reponse protocol.
+Commands are NULL-terminated ASCII strings, one per UDP socket.
+Each command has a corresponding response.
+Every command is of the form:
+
+CMD <cmdtype> [params]
+
+The <cmdtype> is the actual command.
+Parameters are optional depending on the commands type.
+Every response is of the form:
+
+RSP <cmdtype> <status> [result]
+
+The <status> is 0 for success and a non-zero error code for failure.
+Successful responses may include results, depending on the command type.
+
+
+Power Control
+
+POWEROFF shuts off transmitter power and stops the demodulator.
+CMD POWEROFF
+RSP POWEROFF <status>
+
+POWERON starts the transmitter and starts the demodulator.  Initial power level is very low.
+This command fails if the transmitter and receiver are not yet tuned.
+This command fails if the transmit or receive frequency creates a conflict with another ARFCN that is already runnng.
+If the transceiver is already on, it response with success to this command.
+CMD POWERON
+RSP POWERON <status>
+
+SETPOWER sets output power in dB wrt full scale.
+This command fails if the transmitter and receiver are not running.
+CMD SETPOWER <dB>
+RSP SETPOWER <status> <dB>
+
+ADJPOWER adjusts power by the given dB step.  Response returns resulting power level wrt full scale.
+This command fails if the transmitter and receiver are not running.
+CMD ADJPOWER <dBStep>
+RSP ADJPOWER <status> <dBLevel>
+
+
+Tuning Control
+
+RXTUNE tunes the receiver to a given frequency in kHz.
+This command fails if the receiver is already running.
+(To re-tune you stop the radio, re-tune, and restart.)
+This command fails if the transmit or receive frequency creates a conflict with another ARFCN that is already runnng.
+CMD RXTUNE <kHz>
+RSP RXTUNE <status> <kHz>
+
+TXTUNE tunes the transmitter to a given frequency in kHz.
+This command fails if the transmitter is already running.
+(To re-tune you stop the radio, re-tune, and restart.)
+This command fails if the transmit or receive frequency creates a conflict with another ARFCN that is already runnng.
+CMD TXTUNE <kHz>
+RSP TXTUNE <status> <kHz>
+
+
+Timeslot Control
+
+SETSLOT sets the format of the uplink timeslots in the ARFCN.
+The <timeslot> indicates the timeslot of interest.
+The <chantype> indicates the type of channel that occupies the timeslot.
+A chantype of zero indicates the timeslot is off.

-About OsmTRX
-============
-
-OsmoTRX is a software-defined radio transceiver that implements the Layer 1
-physical layer of a BTS comprising the following 3GPP specifications:
-
-* TS 05.01 "Physical layer on the radio path"
-* TS 05.02 "Multiplexing and Multiple Access on the Radio Path"
-* TS 05.04 "Modulation"
-* TS 05.10 "Radio subsystem synchronization"
-
-OsmoTRX is based on the transceiver code from the
-[OpenBTS](https://osmocom.org/projects/osmobts/wiki/OpenBTS) project, but setup
-to operate independently with the purpose of using with non-OpenBTS software and
-projects, while still maintaining backwards compatibility with OpenBTS when
-possible. Currently there are numerous features contained in OsmoTRX that extend
-the functionality of the OpenBTS transceiver. These features include enhanced
-support for various embedded platforms - notably ARM - and dual channel
-diversity support for the Fairwaves umtrx.

+The Transceiver
+
+The transceiver consists of three modules:
+   --- transceiver
+   --- radioInterface
+   --- USRPDevice
+
+The USRPDevice module is basically a driver that reads/writes
+packets to a USRP with two RFX900 daughterboards, board 
+A is the Tx chain and board B is the Rx chain.  
+
+The radioInterface module is basically an interface b/w the
+transceiver and the USRP.   It operates the basestation clock
+based upon the sample count of received USRP samples.  Packets 
+from the USRP are queued and segmented into GSM bursts that are
+passed up to the transceiver; bursts from the transceiver are
+passed down to the USRP. 
+
+The transceiver basically operates "layer 0" of the GSM stack,
+performing the modulation, detection, and demodulation of GSM 
+bursts.  It communicates with the GSM stack via three UDP sockets,
+one socket for data, one for control messages, and one socket to
+pass clocking information.  The transceiver contains a priority
+queue to sort to-be-transmitted bursts, and a filler table to fill
+in timeslots that do not have bursts in the priority queue.  The
+transceiver tries to stay ahead of the basestation clock, adapting 
+its latency when underruns are reported by the radioInterface/USRP.
+Received bursts (from the radioInterface) pass through a simple 
+energy detector, a RACH or midamble correlator, and a DFE-based demodulator.
+
+NOTE: There's a SWLOOPBACK #define statement, where the USRP is replaced
+with a memory buffer.  In this mode, data written to the USRP is actually stored 
+in a buffer, and read commands to the USRP simply pull data from this buffer.
+This was very useful in early testing, and still may be useful in testing basic
+Transceiver and radioInterface functionality.

+  mbz   Must be Zero: these bits must be zero in both IN and OUT packets.
+
+  O     Overrun Flag: set in an IN packet if an overrun condition was
+        detected.  Must be zero in OUT packets.  Overrun occurs when
+        the FPGA has data to transmit to the host and there is no
+        buffer space available.  This generally indicates a problem on
+        the host.  Either it is not keeping up, or it has configured
+        the FPGA to transmit data at a higher rate than the transport
+        (USB) can support.
+
+  U     Underrun Flag: set in an IN packet if an underrun condition
+        was detected.  Must be zero in OUT packets.  Underrun occurs
+        when the FPGA runs out of samples, and it's not between
+        bursts.  See the "End of Burst flag" below.
+
+  D     Dropped Packet Flag: Set in an IN packet if the FPGA
+	discarded an OUT packet because its timestamp had already
+	passed.
+
+  S     Start of Burst Flag:  Set in an OUT packet if the data is the
+        first segment of what is logically a continuous burst of data.
+        Must be zero in IN packets.
+
+  E     End of Burst Flag:  Set in an OUT packet if the data is the
+        last segment of what is logically a continuous burst of data.
+        Must be zero in IN packets.  Underruns are not reported
+        when the FPGA runs out of samples between bursts.
+
+
+  RSSI  6-bit Received Strength Signal Indicator:  Must be zero in OUT
+        packets.  In IN packets, indicates RSSI as reported by front end.
+	FIXME The format and interpretation are to be determined.
+
+  Chan  5-bit logical channel number.  Channel number 0x1f is reserved
+        for control information.  See "Control Channel" below.  Other
+        channels are "data channels."  Each data channel is logically
+        independent of the others.  A data channel payload field
+        contains a sequence of homogeneous samples.  The format of the
+        samples is determined by the configuration associated with the
+        given channel.  It is often the case that the payload field
+        contains 32-bit complex samples, each containing 16-bit real
+        and imaginary components.
+
+  Tag   4-bit tag for matching IN packets with OUT packets.
+        [FIXME, write more...]
+
+  Payload Len: 9-bit field that specifies the length of the payload
+        field in bytes.  Must be in the range 0 to 504 inclusive.
+
+  Timestamp: 32-bit timestamp.
+	On IN packets, the timestamp indicates the time at which the
+	first sample of the packet was produced by the A/D converter(s)
+        for that channel.  On OUT packets, the timestamp specifies the
+        time at which the first sample in the packet should go out the
+        D/A converter(s) for that channel.  If a packet reaches the
+	head of the transmit queue, and the current time is later than
+	the timestamp, an error is assumed to have occurred and the
+	packet is discarded.  As a special case, the timestamp
+	0xffffffff is interpreted as "Now".
+
+	The time base is a free running 32-bit counter that is
+	incremented by the A/D sample-clock.
+
+  Payload: Variable length field.  Length is specified by the
+        Payload Len field.
+
+  Padding: This field is 504 - Payload Len bytes long, and its content
+        is unspecified.  This field pads the packet out to a constant
+        512 bytes.
+
+
+
+"Data Channel" payload format:
+-------------------------------
+
+If Chan != 0x1f, the packet is a "data packet" and the payload is a
+sequence of homogeneous samples.  The format of the samples is
+determined by the configuration associated with the given channel.  
+It is often the case that the payload field contains 32-bit complex
+samples, each containing 16-bit real and imaginary components.
+
+
+"Control Channel" payload format:
+---------------------------------
+
+If Chan == 0x1f, the packet is a "control packet".  The control channel
+payload consists of a sequence of 0 or more sub-packets.
+
+Each sub-packet starts on a 32-bit boundary, and consists of an 8-bit
+Opcode field, an 8-bit Length field, Length bytes of arguments, and 0,
+1, 2 or 3 bytes of padding to align the tail of the sub-packet to
+a 32-bit boundary.
+
+Control channel packets shall be processed at the head of the queue,
+and shall observe the timestamp semantics described above.
