reasons:
* TC_assignment_fr_a5_4() runs an unusual sequence of messages: it first
fully assigns an lchan, and after that sends a Cipher Mode Command.
Usually, the ciphering happens as part of attaching (Compl L3).
The new test TC_assignment_fr_a5_not_sup() does the ciphering in the
usual sequence, and properly expects a Cipher Mode Reject.
* TC_assignment_fr_a5_4 means to ask for an *unsupported* encryption
algo. Since we are going to introduce A5/4 support shortly, we'll need
to free up this name, for a successful A5/4 encryption test.
New test TC_assignment_fr_a5_not_sup() asks for A5/5 encryption, which
is not supported.

shortly after exiting the function and provoke a Dynamic Test Error

Since Idb453fc894584ccf4f5f8b45a24421db958e9478, osmo-bsc does send
ip.access specific Measurement Pre-Processing Defaults. This message

And it went unnoticed that the ttcn tests expect a MultiRate config of

See mr_conf = '2804'O, where the '8' indicates ICMI = 1.

the expected ICMI value and Start Mode, i.e. ICMI = 1 and StartMode = 0,
which is configured by 'amr tch-[fh] start-mode 1'. This should make

The Mobile Allocation IE generated by the IUT includes not only
the list of hopping ARFCNs, but also ARFCN of the transceiver
itself. This is the correct behaviour, and that's why we see
sporadic test case failures like this one:
Mobile Allocation IE does not match (tn := 1):
{ len := 3, ma := '001010101011111100000000'B }
vs expected
{ len := 2, ma := '0010101010111111'B }
The last '0'B bits may look like redundant padding, but actually
only 7 of them are. The MSB '0'B bit in the last (third) octet
corresponds to pre-configured ARFCN 871.
Since f_TC_fh_params_gen() generates all ARFCNs in GSM-900:
- in f_TC_fh_params_gen(), pick an ARFCN value from GSM-900;
- in f_TC_fh_params_set(), change ARFCN of a given transceiver;
- in f_TC_fh_params_gen_tr_ma(), consider that ARFCN;
- in f_TC_fh_params_unset(), bring it back to 871.

This scenario appeared in jenkins runs of BSC_Tests making

could however not reproduce it on my local docker setup because it
really seems like a timing race condition.
The scenario is:
TTCN3 -> BSC: RESET
TTCN3 <- BSC: RESET
TTCN3 -> BSC: RESET-ACK
In there, TTCN3's f_legacy_bssap_reset() expected a RESET-ACK to be
received, but it may well be that the other end never saw the RESET and
hence it will never sent the RESET-ACK, since it indicated it became
available afterwards. In that case (RESET received), let's not fail if a
RESET-ACK is never received, since the connection is actually in the

My initial assumption was that we can skip redundant '0'B bits or
even '00'O octets in the Mobile Allocation IE, and thus reduce
the overall size of this element. Unfortunately, this is wrong.
3GPP TS 44.018, section 10.5.2.21 clearly states that the Mobile
Allocation IE contains a bit-string of size NF, where NF is the
number of frequencies in the cell allocation. If NF % 8 != 0,
then '0'B padding bits must be appended to make it octet-aligned.
In other words, if the cell allocation contains let's say 13
frequencies, but a hopping timeslot makes use of only a small
fraction of it (e.g. 4 first channels), we would still need to
transmit at least 13 bits (+padding), including all redundant
bits and octets.

Some tests may stop without cleaning up the CBSP state. Avoid affecting
subsequent tests by clearing the state for each f_cbsp_init_server().
Some ETWS CMD may still be left in the RSL queue (from the time period passing
between a stopped test and the next test starting up), so clear all RSL ports.
To be able to do so, move f_cbsp_reset_bss() to the cbsp_test_CT, from where it
can access both CBSP and IPA_RSL[] ports. All current callers are on
cbsp_test_CT anyway.
This patch should fix TC_cbsp_emerg_write_bts_cgi_cchan and
TC_cbsp_emerg_write_bts_cgi_cchan_disable, which so far break because of
leftover ETWS CMDs in the RSL queue from the preceding test run.

For each CBSP test, define one global set of CBSP msg id and serno for use by
that test.
Each CBSP test should use a distinct message id and serial nr, to not get mixed
up with previous state. But keeping those numbers manually is a confusing pain,
and as a reader it is hard to follow how these numbers change (if they do).
In f_cbsp_init_server(), require a preset of msg id and serno to be used in
that test, and from then on only use g_cbsp_msg_id and g_cbsp_ser_no instead of
magic numbers. If they change, write it out explicitly, making it easy to
follow what is expected to happen, and also making it easy to copy-paste code
snippets without having to manually adjust magic numbers.
Choice of numbers: pick a simpler scheme where both msg_id and ser_no share a
common "prefix" in the 1000s range, and for a ser_no add 500 to keep distinct
numbers (that avoid confusion when reading the logs):
test prefix msg_id ser_no next-ser_no
1 1000 1001 1501 1502
2 2000 2001 2501 2502
3 3000 3001 3501 3502
...
E.g. the first test has the prefix of 1000.
msg_id: 1001, ser_no: 1101.

Recently fixed errors in the last_block counting as well as encoding ask for a
proper test coverage of various lengths, which also verifies the expected
blocks count explicitly.
Implement this in TC_cbsp_write_bss():
Run f_tc_cbsp_write_bss() multiple times with differing fixed payload lengths,
at all block count transitions, plus some arbitrary lengths in-between.
Before this patch, TC_cbsp_write_bss() would pick a different random payload
length for every test run, which, until recently, then sporadically hit
last_block value errors. That's not good for reproducability.

messages. However if EMERGENCY CALLS are allowed on a BTS or not is set
in the system information. Also osmo-bsc has the option to deny
EMERGENCY CALLS globally for all BTSs.
Since EMERGENCY CALLS are a crucial application, the BSC should not only
send the appropiate sysinfo messages that forbid emergency calling. It
should also make sure that any attempt to make an emergency call is
rejected early if emergency calls are denied.
Lets add some checks to verify that the allow/deny mechanisms for

osmo-bsc takes a while to notice that a connected MSC is no longer connected.
Once the mscpool tests have run, the additional msc 1 and msc 2 still linger
around even though the BSSMAP link is no longer served by the bsc-tester.
The easiest way to ensure that only expected MSCs are contacted is to set
'no allow-attach' for each MSC that should not be in use.
So, the default setup is 'allow-attach' on msc 0, and 'no allow-attach' on mscs
1 and 2. In f_init(), allow attach on those MSCs indicated by the nr_msc
amount. The entire vty transaction to configure attach/no attach for all three
MSCs takes about 4 micro seconds in my test setup, so it is fine to do this
during f_init() for each BSC test.
After this, tests running after the MSC pooling tests (the LCLS tests) no
longer round-robin their subscribers across disconnected MSCs.
NOTE: it would be good to somehow detect more reliably in osmo-bsc that an MSC
is gone and not use it anymore. That is however not so trivial. To get the LCLS
tests back online, this is a workaround to avoid that complexity for now.

The TC_ho_neighbor_config_* tests sometimes take longer than 30 seconds,

0/0/0 to 99/0/0 to make TC_oml_unknown_unit_id pass again. The test was
failing, because a new bts that matches 0/0/0 was added to osmo-bsc.cfg
in [1], [2] and [3].

The testcase TC_paging_resp_unsol expects the BSC to close the channel
when an unsolicit paging response is received. This expectation is due
to the fact that osmo-bsc supports multiple MSC, which is not specified
in 3gpp specs. Therefore the BSC needs to know which MSC is in charge.
However, with MT-CSFB calls it is a normal situation that the BSC
receives a paging response on abis without sending a paging first since
the MSC has paged the UE via the SGs interface. In those cases we expect
the BSC to forward the paging response to the first configured MSC.

Since osmo-bsc commit "neighbor config: allow re-using ARFCN+BSIC pairs"
(I29bca59ab232eddc74e0d4698efb9c9992443983), osmo-bsc considers only those
cells as neighbors that are explicitly listed, or all local cells if none are
listed. This lead to breaking TC_ho_int, because the osmo-bsc.cfg has only one
remote-cell neighbor for bts 0, and hence a handover to local cell bts 1 is now
regarded as invalid.
The remote-cell neighbor is needed for inter-BSC handover tests; also consider
that the TC_ho_neighbor_config_* tests each place individual neighbor
configuration by live VTY interaction.
Hence make all of these tests more robust: remove the neighbor config from the
osmo-bsc.cfg file, and instead include VTY interaction for each test case that
sets the particularly needed neighbor configuration at runtime.
An analogous osmo-bsc.cfg change in docker-playground is in change
If44dd6b578cdc55076c8180707d1c2d69fe5f2a8.
(It is not actually harmful to leave the neighbor config in osmo-bsc.cfg, but
remove that since it is also not needed anymore.)

Add tests to play through various neighbor configurations.
Tests will pass as soon as osmo-bsc I29bca59ab232eddc74e0d4698efb9c9992443983
is merged.
Add RSL2 to allow triggering handover to BTS 2.
Adjust osmo-bsc.cfg to match the new tests. Also applied in docker-playground
I1c57a04747f5ec004ccf4657954dcb0b003c24fc.
- Actually enable handover.
- Add bts 3

Make sure that the RR is released only after the MSC has sent the Clear Command:
- first expect a Clear Request from osmo-bsc and return a Clear Command,
- only then accept RR release messages.
See 3GPP TS 48.008 3.1.5.3.3 "Abnormal Conditions": "The terrestrial resource
in the old BSS shall remain assigned until a CLEAR COMMAND message is received
from the MSC"
osmo-bsc already complies, the test should continue to pass.

BSC waits to receive a ClearCommand in response to its ClearRequest
before it starts tearing down the MGCP conn on the MSC-side of the MGW
endpoint.
As a result, expected DLCX was not being sent which made test fail.
However, currently test still fails because current osmo-bsc master
sends a repeated ClearRequest message in this scenario.

* MGCP-over-IPA handling in MSC_ConnectionHandler means we need to use
the new MGCP_CLIENT_MULTI port since we'll be managing MGCP messages
from 2 different UDP connections, and we need to be able to route
answers correctly. As a result, parameter multi_conn_mode is enabled for
SCCPlite and all code adapted to use that port in that type of scenario.
* iDuring calls when on SCCPlite, send a full (all-required-params-in)
CRCX through the MGCP-over-IPA connection towards the BSC in order to
emulate the MSC, and expect the correct answer back. This way we test
BSC funcionality to forward MGCP messages coming from MSC works as
expected.

* Some scenarios like MGW BSC-attached in SCCPlite require handling of
2 MGCP-over-UDP sockets in MGCP Emulation: 1 for regular
libosmomgcp-client from osmo-bsc and another one from the forward socket
from osmo-bsc (of MGCP-over-IPA messages communicated with MSC).
* Old port is kept for backward compatibility with other tests and
enabled by default. It's also interesting to keep it because it makes
tests without special needs (2 sockets) to use the old port/API which
produces simpler code to read and mantain.
* Users of the new port have to enable multi_conn_mode parameter and
expect to interact with port MGCP_CLIENT_MULTI instead of MGCP_CLIENT,
which will offer messages containing information about the UDP
connection being used by that message.

Move logic handling CRCX and MDCX to function, so they can be reused for
other ports in forthcoming commits.

* TTCN3 code was not ACKing the DLCXs, and as a result retransmitted
DLCX BSC->MGW were being counted as 2nd DLCX.
* In SCCPLite, only 1 DLCX is expected BSC->MGW, because the BSC only
takes care of the BTS-side conn in the endpoint, while MSC takes care of
the MSC-side conn (which is not sent in this case because doesn't really
involved the BSC other than forwarding the message, which will already
be tested in other places in forthcoming commits).
* Getting rid of retransmissions by ACKing the DLCX, it unconvers a bug
in TC_ho_out_fail_no_ho_detect when on AoIP, where BSC only deletes one
of the 2 previously created connections.
* Code is refactored into the function because its logic is made more
complex, and may be even more complex in forthcoming commits when we add
MGCP-over-IPA forwarding verification support.
