We should check this as well.<br><br>(The PCH is part of the CCCH, which also contains the<br>AGC. How many blocks of the CCCH are to be used by the PCH is set by the<br>parameter bs_ag_blks_res.)<br><br>- Check the FN of each paging message that arrives on L1CTL and make<br> sure that those FN are part of the PCH.<br><br>Change-Id: I839e75ece05166518bf7132acd3017434b3d3bc2<br>Related: OS#1575<br>---<br>M bts/BTS_Tests.ttcn<br>1 file changed, 59 insertions(+), 3 deletions(-)<br><br></pre><pre
