- * generating the events.

- * 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 conditions (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,

+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.

+
+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.

-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

+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.

+transmission and signaling on the USRP.  All packets are 512-byte long,
+and are transfered using USB "bulk" transfers.
+
+IN packets are sent towards the host.
+OUT packets are sent away from the host.
+
+The layout is 32-bits wide.  All data is transmitted in little-endian
+format across the USB.

+  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.

 With multi-ARFCN enabled, ARFCN spacing is fixed at 800 kHz or 4 GSM channels.
 So if TRX-0 is set to ARFCN 51, TRX-1 _must_ be set to 55, and so on. Up to
 three ARFCN's is supported for multi-TRX.

 leaving apart of course the mentioned ARFCN limitations explained above and as a
 consequence physical installation and operational differences.
