-  - FR enabled
-  - EFR enabled
-  - AMR 12.2 enabled (and all other modes disabled !)
-  - Use `amr-payload octet-aligned` in BSC config
-
-* Check BTS config
-  - Disable jitter buffer : `bts N / rtp jitter-buffer 0`
-
-* Check BSC config
-  - Disable radio timeout : `network / bts n / radio-link-timeout infinite`
-
-* Start BER testing tool
-  - `./rtp_ber 4000`
-
-* On the MSC CLI, start a silent-call, then request GSM to test loop
-  - `subscriber imsi <XXX> silent-call start tch/f speech-amr`
-  - `subscriber imsi <XXX> ms-test close-loop b`
-
-  Don't forget to terminate the loop and terminate the silent call !

-/* RTP based GSM BER testing for osmo-bts, implementing ideas described in
- * https://osmocom.org/projects/osmobts/wiki/BER_Testing
- *
- * In short: The command transmits a PRBS sequence encapsulated in RTP frames, which are sent
- * to the BTS, which transmits that data in the (unimpaired) downlink.  The mobile station
- * receives the data and is instructed to loop it back in the (possibly impaired) uplink.
- * The BTS receives that uplink, puts in in RTP frames which end up being received back by this
- * very tool.  By correlating the received RTP with the PRBS sequence, this tool can compute
- * the BER (Bit Error Rate) of the (possibly impaired) uplink.  Doing this with different
- * RF channel model simulators in the uplink allows to establish BER at different levels and
- * channel conditions. */

-Description: Base Transceiver Station for GSM
- OsmoBTS is a software implementation of Layer2/3 of a BTS. It implements the
- following protocols/interfaces:
-    LAPDm (GSM 04.06)
-    RTP
-    A-bis/IP in IPA multiplex
-    OML (GSM TS 12.21)
-    RSL (GSM TS 08.58)
- .
- OsmoBTS is modular and has support for multiple back-ends. A back-end talks to
- a specific L1/PHY implementation of the respective BTS hardware. Based on this
- architecture, it should be relatively easy to add a new back-end to support
- so-far unsupported GSM PHY/L1 and associated hardware.

-=== ETWS (Earthquake and Tsunami Warning System)
-
-ETWS as specified in 3GPP TS 23.041 includes not only notification via
-SMSCB, but also so-called Primary Notifications (PN).  The ETWS PN are
-transmitted
-
- * by the BSC to all subscribers with active dedicated channels
- * by the BTS on the PCH to all subscribers in idle mode
- * by the PCU on the PACCH to all subscribers with active TBF
-
-Unfortunately, 3GPP forgot to update their specifications with any
-information as to how the ETWS PN is transmitted from BSC to BTS in
-a portable way, and Osmocom had to invent their own non-standard
-signaling for it.
-
-See <<OSMO_ETWS_CMD>> for the Osmocom implementation.

-=== BCCH carrier power reduction operation
-
-According to 3GPP TS 45.008, section 7.1, the BCCH carrier (sometimes called C0) of
-a BTS shall maintain discontinuous Downlink transmission at full power in order to
-stay "visible" to the mobile stations.  Because of that, early versions of this 3GPP
-document prohibited BS power reduction on C0.  However, a new feature was introduced
-version 13.0.0 (2015-11) - "BCCH carrier power reduction operation".
-
-This is a special mode of operation, in which the variation of RF power level for
-some timeslots is relaxed for the purpose of energy saving.  In other words, the
-output power on some timeslots, except the timeslot(s) carrying BCCH/CCCH, can be
-lower than the full power.  In this case the maximum allowed difference is 6 dB.
-
-Unfortunately, 3GPP did not specify in which way the BTS is instructed to activate
-and deactivate the BCCH carrier power reduction mode.  Osmocom had to invent their
-own non-standard approach: the BSC needs to send _BS POWER CONTROL_ message with
-the _Channel Number_ IE set to 0x80 (BCCH) and the _Message Discriminator_ set to
-0x06 (Common Channel Management messages).

 Set the number of frames to be transmitted to transceiver in advance of
 current GSM frame number.

-GSM is a TDMA (time division multiple access) system on the radio
-interface.  OsmoTRX is the "clock master" of that in the Osmocom
-implementation. It informs OsmoBTS of the current GSM frame
-number.  However, as there is non-zero delays (UDP packet transmission
-delay, operating system scheduler delay on both OsmoTRX and OsmoBTS
-side, ...), OsmoBTS must compensate for that delay by "advancing"
-the clock a certain amount of time.
-
-In other words, if OsmoTRX informs us that the current frame number is N,
-we advance it by `fn-advance` and transmit burst data for
-`N + fn-advance` towards OsmoTRX.
-
-The fn-advance should be kept as low as possible to avoid additional
-delays to the user voice plane as well as to improve the performance
-of the control plane (LAPDm) as well as GPRS.
-
-However, fn-advance must be kept sufficiently high to ensure no
-underruns on the OsmoTRX side.
-
-The detailed value will depend on your underlying computer systems,
-operating system and related tuning parameters.  Running OsmoTRX
-on a remote host will inevitably require a higher fn-advance than
-running it on the same machine, where the UDP packets are just passed
-over the loopback device.

-the control plane, RTP for the voice plane, and OsmoPCU for GPRS) to
-generate a MAC block and input it into the osmo-bts-trx TDMA scheduler.
-
-If OsmoTRX reported N as the current frame number, the actual frame number

-=== Osmux Support in {program-name}
-
-Osmux usage in {program-name} in managed through the VTY commands in node
-`osmux`. Command `use (on|off|only)` is used to configure use policy of Osmux
-within {program-name}. Once enabled (`on` or `only`), {program-name} will
-announce the _OSMUX_ BTS feature towards the BSC over OML. This way, the BSC
-becomes aware that this BTS supports using Osmux to transfer voice call user
-data when the AMR codec is selected.
-
-It is then up to the BSC to decide whether to use Osmux or not when establishing
-a new call. If the BSC decides to use Osmux for a given call, then the _IPACC
-CRCX/MDCX_ messages sent by the BSC will contain an extra _Osmux CID_ IE
-appended, which contains the Osmux CID to be used by the BTS to send Osmux
-frames to the co-located BSC MGW (aka the BSC MGW' local CID, or {program-name}'
-remote CID). The IP address and port provided in the same messages refer to the
-address and port where Osmux frames with the provided CID are expected to be
-received. Similarly, {program-name} appends an _Osmux CID_ IE to the _IPACC
-CRCX/MDCX ACK_ message it generates, this time with its own local Osmux CID.
-Same goes for the BTS' local IP address and port where Osmux frames are expected
-to be received.
-
-{program-name} will behave differently during call set up based on the VTY
-command  `use (on|off|only)` presented above:
-
-* `off`: If _IPACC CRCX_ from BSC contains _Osmux CID_ IE, meaning
-  BSC wants to use Osmux for this call, then {program-name} will reject the
-  request and the call set up will fail.
-* `on`: {program-name} will support and accept both Osmux and non-Osmux (RTP)
-  upon call set up. If _IPACC CRCX_ from BSC contains the _Osmux CID_ IE on a
-  AMR call (`Channel Mode GSM3`), it will set up an Osmux stream on its end and
-  provide the BSC with the BTS-local CID. If the BSC provides no _Osmux CID_ IE,
-  then {program-name} will set up a regular RTP based call.
-* `only`: Same as per `on`, except that {program-name} will accept only Osmux
-  calls on the CN-side, this is, if  _IPACC CRCX_ from BSC doesn't
-  contain an _Osmux CID_ IE, it will reject the assignment and the call set up
-  will fail. This means also that only AMR calls (`Channel Mode GSM3`) are
-  allowed.

-==== Full example of QoS for osmo-bts uplink QoS

-. configure the osmocom program to set the DSCP value
-. configure an egrees QoS map to map from priority to PCP

- rtp ip-dscp 46

-.Example Step 2: egress QoS map to map from socket priority to PCP values
----
-$ sudo ip link set dev eth0.9<1> type vlan egress-qos-map 0:0 1:1 5:5 6:6 7:7 <2>
----
-<1> make sure to specify your specific VLAN interface name here instead of `eth0.9`.
-<2> create a egress QoS map that maps the priority value 1:1 to the PCP. We also include the
-    mapping 1:1 from the osmo-pcu example (see <<userman-osmopcu>>) here.
-
-NOTE:: The settings of the `ip` command are volatile and only active until
-the next reboot (or the network device or VLAN is removed).  Please refer to
-the documentation of your specific Linux distribution in order to find out how
-to make such settings persistent by means of an `ifup` hook whenever the interface
-comes up.  For CentOS/RHEL 8 this can e.g. be achieved by means of an `/sbin/ifup-local
-script` (when using `network-scripts` and not NetworkManager).  For Debian or Ubuntu,
-this typically involves adding `up` lines to `/etc/network/interfaces` or a `/etc/network/if-up.d`
-script.

-        Access Burst is the first burst a mobile transmits in order to establish a connection and it
-        is used to estimate Timing Advance (TA) which is then applied to Normal Bursts to compensate
-        for signal delay due to distance. So changing this setting effectively changes maximum range
-        of the cell, because Access Bursts with a delay higher than this value will be ignored.

-        USE FOR TESTING ONLY, DO NOT CHANGE IN PRODUCTION USE!
-        During the normal operation, delay of Normal Bursts is controlled by the Timing Advance loop
-        and thus Normal Bursts arrive to a BTS with no more than a couple GSM symbols, which is
-        already taken into account in osmo-trx. Changing this setting will have no effect in
-        production installations except increasing osmo-trx CPU load. This setting is only useful
-        when testing with a transmitter which cannot precisely synchronize to the BTS downlink
-        signal, like R&amp;S CMD57.
