Subsequent patch I3cace19f9e5adc8ebab13ef2328a36dc150b2b31 adds a test with
specific payload lengths. To verify the correctness of the number-of-blocks
calculation (recently fixed), allow pinpointing the expected blocks count.

Keep the default of using a random payload length, but also allow picking one
specifically. TC_cbsp_write_bss() will use this in a subsequent patch.
Change-Id: I259da42cbcbfdfe930aabb45c9de8a2b67c69629
Fix the length calculation to provide a range of [1..82].
f_rnd_int() generates [0..max[ (i.e., < max), so f_gen_page() so far has a
payload len range of [0..81]. We want no zero payload, and we want a maximum of
82 bytes (page max of 88 minus 6 header bytes).
Change-Id: Id521b6038a23dc8e71ea25475bcdef7bc8917531
When dividing the payload by 22, the initial 6 header octets must also be taken
into account.
And, the last_block value indicates 4 as 0, which is not encoded correctly
before this patch. Add a separate f_cbsp_block_count_enc() to fix the
calculation.

The bsc/BSC_Tests_CBSP.ttcn rely on a configuration where the first three BTS
carry out SMSCB messaging, and the fourth BTS does not. That requires a CBCH

- adjust the number of available SDCCH (for TC_chan_exhaustion).
- there now is a CBCH channel description in SI4, add this to

In the ttcn3-bsc-latest tests, there are no 'msc 1' and 'msc 2' configured, so
stepping into 'msc 1' and '2' creates two new, empty MSC configurations.
osmo-bsc latest actually still tries to use them and fails 2/3 Compl L3.
So do not step into 'msc' config scopes if no such MSC is mentioned in the

The EMERGENCY SETUP is an L3 message that normally gets passed through
transparently to the A interface. Nomrally the BSC will not look into L3
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
EMERGENCY CALLS are working as expected.

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,
because they run multiple handovers. Since they don't have access to the
Test_CT, they cannot restart the T_guard. The simplest solution is to choose a
longer T_guard timeout for those tests specifically, by adding an argument to
f_init(). (A longer timeout for those tests is following in another patch.)
Why f_init()? Assigning a different default value to T_guard seems to not be
possible, but a different timeout value can be passed to T_guard.start(), which
happens in f_init().

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.

Since we use some BSSMAP extensions to signal Osmux, we need to maintain
our own fork of BSSMAP_Types in order to supports those IEs in BSSMAP
RESET and BSSMAP Assin Req/Compl. Hence, switch all build componenets to
fetch and use our fork.

Randomly, this test issues the Clear Command so fast that the MGW has not yet
been set up, and hence the test cannot possibly see DLCX for endpoint conns
that haven't been set up at all. So, simply wait a bit before clearing.

The RAN_Emulation currently unconditionally provides BSSAP and MGCP support.
Let's re-structure the code so that support for those protocols is now
possible to enable/disable at compile time.
This patch is in preparation of introducing RANAP support in RAN_Emulation.

So far, BSSMAP_Emulation supported only a transport over BSSMAP.
However, we soon intend to merge support for RANAP in order to
simulate RANAP/Iu connections as well as BSSMAP. Let's start
by renaming some of the existing types/functions/ports/modules
without introducing any functional changes just yet.

Make sure that the S15-S0 related testcases are only executed when AoIP
is used as transport.

The S15-S0 related testscases are missing from the expected-results.xml
file. Lets add them.

The handling of the AMR rate configuration bits S15-S0 is currently only
superficially checked. Lets add more some more elaborated testcases to
check through varios different situations. Also make sure that the
resulting mr configuration IE is verified

The testcase TC_assignment_codec_amr_f uses a combination of S-Bits that
has S1 which configures a set of four rates at once. This is quite a
complex situation and since the BSC was upgraded with new features
affecting the behavior in this special case lets simplify this testcase
for now.

When a MSC releases a connection using the BSSMAP CLEAR CMD, it can
specify that this call was part of CSFB.
The BSC is then supposed to add a special IE to the RR RELEASE
message which will help the phone to switch back to LTE as soon
as possible.
This commit adds a new test case testing for exactly that behavior.
The test does *not* verify if the EARFCN information contained is
actually correct, only that the IE is present in the RR RELEASE.

The 'decmatch' keyword allows us to match the decoded version of some
octetstring, which is very useful in the situations where we have
the L3 message only as octetstring but want to check if it matches
some L3 template.

The RR RELEASE message does not always have to be '060D00'O,
which constrains it to:
* not having any optional IEs
* not having a cause value != 00
Let's relax the matching to accept any RR RELEASE message, whatever
the cause may be, and whether or not there are any optional IEs at the
end.
At the same time, also remove some copy+pasting but rather have one
template that gets used everywhere.

The tests presented in Change I109d986dd7ece1a56422a669ca64353ed46f7ed6,
are using a slightly outdated vty syntax and fail because of that. Lets
update the VTY syntax.

When a channel is assigned via the assignment request throught the A
interface, the MSC may offer either FR, HR or both. When FR and HR are
permitted, a preference is set on one of the two.
At the moment we do not check how the bsc is reacting to those
preferences and its also not checked how the behavior is when the
preferred rate is not available because all lchan of that type are
already in use. Lets add a set of tests to verify this.

Previous RA value (23, Establishment cause = 0010XXXX) meant MS was dual
rate capable but was asking speciifically for only TCH/F channel. As a
result, TCH/H was not being allocated and an immediate assignment reject
was sent.

When an internal handover is performed, the BSC is expected to inform
the MSC about the event by sending a BSSMAP HANDOVER PERFORMED message.
This feature was missing in the BSC and has now been added. The tests
need to be upgraded in order to handle the additional message.
- Upgrade f_tc_ho_int so that it expects a HANDOVER PERFORMED message

TC_paging_resp_unsol spent some time in gerrit before being merged. As a
result, other commits were merged in between the test was submitted (tested)
and merged. As a result, commit a5302c8151
was merged while this test was still in gerrit and thus was not updated
accordingly.
Similar stuff happened with the osmo-bsc commit fixing the scenario this
test was showcasing: The osmo-bsc patch (77cd1129931928d2a6e7667d0374feeeed71b0ce)
had merge conflict with other osmo-bsc commits merged in-between,
and was merged even later than the commit introducing this TTCN3 test, so
failures were expected for this test for a while.
