In cases a), b), c), d), and e) we're sending one or more Measurement
Reports via the A-bis/RSL, and then immediately triggering a traffic
channel assignment by calling f_TC_chan_alloc_algo(), which sends an
Assignment Request via the A interface.
The above-mentioned messages are sent immediately all together, so it
may happen that the BSC handles the Assignment Request earlier than
the Measurement Report(s). In this case there will be no RxLev
samples, so the BSC would fall-back to ascending allocation order.
Recently we saw this race condition actually happening on Jenkins:
https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-bsc-test-sccplite/1583/
Let's introduce an artificial delay before sending the Assignment
Request, so that the BSC has enough time to process received MRs.

That config is used to control the use of osmux between BSC<->MSC. Since

separate way. Let's rename it so that we can add a "use_osmux_bts" later
on.

BSC_Tests_CBSP was sending an ETWS message but using non-ETWS templates

This test case verifies the new channel allocation mode, which
is expected to switch between ascending and descending modes
dynamically based on the following two configurable parameters:
* Uplink RxLev threshold (and min number of samples),
* C0 (BCCH carrier) channel load threshold.
The test case scenario includes:
Case a) Unknown Uplink RxLev => fall-back to ascending.
Case b) Not enough RxLev samples => use ascending.
Case c) Uplink RxLev below the threshold => use ascending.
Case d) Uplink RxLev above the threshold => use descending.
Case e) Uplink RxLev above the threshold, but C0 load is not.

The aim of these new test cases is to verify both ascending and
descending modes of the BSC's channel allocator. Both tests are
using BTS2, which has 4 TRX instances.
The common test scenario can be described as follows:
1. Establish an SDCCH channel, send some dummy payload on it.
2. Send a BSSMAP Assignment Request for a TCH/F channel.
3. Expect RSL CHANnel ACTIVation for a TCH/F channel.
4. Respond with RSL CHANnel ACTIVation NACK (*).
5. Expect a BSSMAP Assignment Failure.
These steps are repeated several times. Note (*) that for the
sake of simplicity, I am aborting the assignment procedure by
sending a NACK, so that the requested logical channel becomes
BORKEN and behaves like an occupied one until the A-bis/OML
link is re-established. This reduces the overall complexity.

Recently I noticed sporadic CBSP test case failures on Jenkins:
Timeout waiting for RSL_OSMO_ETWS_CMD (disable)
BSC_Tests_CBSP.ttcn:1209 BSC_Tests_CBSP control part
BSC_Tests_CBSP.ttcn:1056 TC_cbsp_emerg_write_bts_cgi_cchan_disable
The related timeout is set to 5.0 seconds in f_exp_rsl_etws(), what
matches the Warning Period IE sent in CBSP WRITE-REPLACE message.
Adding a debug log printing T.read on receipt of RSL_OSMO_ETWS_CMD
reveals that we're cutting it too close: the message arrives just
a few milliseconds before the timeout expires.
f_exp_rsl_etws(): T := 4.999196s, remaining 0.000804s
f_exp_rsl_etws(): T := 4.998683s, remaining 0.001317s
f_exp_rsl_etws(): T := 4.999344s, remaining 0.000656s

Similar to [1], this is happening because the VTY command setting

So far it was possible to communicate with multiple BTS instances,
however we were limited to only one IPA/RSL connection per BTS.
Communicating with additional TRX instances requires establishing
additional per-TRX IPA/RSL connections. This patch extends the
testsuite infrastructure, so that it becomes possible to have
up to 4 individual TRX instances for each BTS.
* Introduce record 'BtsParams', store per-BTS params in an array.
* IPA_RSL_PT: test_CT.IPA_RSL[NUM_BTS] -> test_CT.IPA_RSL[NUM_BTS][NUM_TRX].
* BTS_State: test_CT.bts[NUM_BTS] -> test_CT.bts[NUM_BTS][NUM_TRX].
* f_init_bts_and_check_sysinfo() accepts number of TRX instances.
* f_init_bts() accepts number of TRX instances to configure.
* f_ipa_rsl_start() accepts a BtsTrxIdx param.
* Introduce record BtsTrxIdx allowing to specify BTS/TRX index values.
* f_ipa_tx(), f_exp_ipa_rx() accept a BtsTrxIdx param (default {0, 0}).
* f_est_dchan[_dyn]() accept a BtsTrxIdx param (default {0, 0}).
** and store the given BtsTrxIdx in returned DchanTuple.
* f_chreq_act_ack() accepts a BtsTrxIdx param (default {0, 0}).
* f_expect_chan_rel() accepts a BtsTrxIdx param (default {0, 0}).
* f_exp_ipa_rx_nonfatal() accepts BtsTrxIdx (default {0, 0}).
* f_exp_chan_rel_and_clear() uses BtsTrxIdx indicated in the given DchanTuple.
* Fix CTRL/statsd expectations in TC_stat_num_bts_connected_[123].
* Fix CTRL expectations in TC_ctrl_trx_rf_locked.
The major limitation is that MSC_ConnHdlr components still have no
access to additional TRX instances - this can be implemented later.

When running ttcn3-bsc-test against osmo-bsc in SCCPlite mode,
TC_lost_sdcch_during_assignment fails with the following output:
Local verdict of MTC: fail reason: "Timeout of T_guard"
Final verdict of PTC: fail reason: "Unexpected DLCX received"
One key problem is that in f_TC_lost_sdcch_during_assignment() we
expect to receive a DLCX message on port MGCP, but somehow it gets
caught by the as_Media_mgw earlier than we attempt to receive it.
* Fix this race condition by activating the as_Media_mgw with
fail_on_dlcx := false, so that it does not catch DLCX messages.
Another problem is that for SCCPlite we're running the MGCP_Emulation
component with multi_conn_mode=true, so that all MGCP messages are
arriving at port MGCP_MULTI (not MGCP) wrapped into MGCP_RecvFrom.
* Expect the DLCX message on either of the two ports depending
on the value of g_pars.aoip (AoIP or SCCPlite mode).
This change makes BSC_Tests.TC_lost_sdcch_during_assignment pass.

These test cases sporadically fail on Jenkins and 9/10 times on my

RSL CHANnel ReQuireD and the VTY command simultaneously, and the
later may be handled earlier than the former by osmo-bsc.
Ensure that the RSL message is handled first by sending the VTY
command after we have received the RSL CHANnel ACTivation message.

First, page only on BTS0, not all the BTS. This simplifies the test and
also makes the subscriber be refcounted only on BTS0.
Then, drop the OML connection after receiving all the expected paging

After osmo-bsc Change-Id I1ae6d97152c458247bc538233b97c2d245196359,
initial requests are prioritized over retransmits.
Before that feature was in place, when sending 500 requests in this test
to the BSC, it could happen that the paging scheduler triggered (every
500ms) before all the 500 requests were received at the BSC. As a
result, the scheduler would put some requests to the end of the queue
after sending an initial request for it towards the BTS. If later more
requests where received from TTCN3, they'd be put at the end, after the
retransmissions.
As a result, the emulated BTS would in general receive retranmits for
the first bunch of requests before receiving the initial transmit of the
later requests.
Ths is no longer the case since the osmo-bsc is prioritizing now the
initial requests. Hence, we'll only start receiving retransmits after
all the new paging requests are received.
