Description

We are not sure this is working correctly nowadays (and maybe it's not even implemented).

We need to check manually if it is implemented and make sure it is working fine. Ideally, we should test this in TTCN3 BTS_Tests.

In theory this can already be checked in osmo-gsm-tester. We need to add a testsuite which enabled dynamic channels as well as edge with a B200. Currently we test both but separately. See suites:
dynts:trx-b200+mod-bts0-dynts67-osmo
gprs:trx-b200+mod-bts0-egprs

According to [1], SETSLOT is being sent to osmo-trx when a dyn ts channel is modified (PDCH ACT/DEACT).

Assigning to fixeria since he was the initial one having concerns about this perhaps being broken, so he can validate everything's fine.
