Alexander Chemeris e510c84860 trx: Implement BER calculations. 
A known issue with this code is that BER is not updated for lost TCH frames,
because osmo-trx doesn't send any indication for them and we don't have
a callback to handle this.

Otherwise the code seem to work fine.

Thomas Tsou d913322b47 TRX: Remove extra TCH/HS puncturing value 
3GPP TS 05.03 "Channel coding" specifies the puncturing matrix (1,0,1)
for class 1 information bits and tail bits valued u(0) to u(103) for a
maximum puncturing index of 311. The puncturing index 313 exceeds the
maximum index and causes osmo_conv_get_output_length() to output the
improper length of 210 instead of 211.

Ivan Kluchnikov eac3b8c2a6 fix: make sysmobts tests only when sysmobts is enabled 2014-05-07 18:09:06 +04:00
Andreas Eversberg d7a3b630b4 TRX: Check if Transceiver indicates an out of range clock 
If frame number is out of range (>= 2715648), the scheduler's process
would end up in an infinite loop. This is because the loop would schedule
bursts until the indicated frame number is reached, which would not be
possible.

The openbts, calypso-bts and osmo-trx might send out out of range clock
indications every 3.5 hour.

Andreas Eversberg 4802b76185 TRX: Add VTY option to allow setting RTS advance in frames 
RTS (ready-to-send) must be issued in advance, so BTS core and especially
osmo-pcu can provide downlink data frames early enough. In some cases PCU
might provide frames too late, so they must be dropped. If PCU provides
frames too late, due to high system load, this "RTS advance" setting must
be increased.

Martin Hauke cc723f630e build: Use AM_CPPFLAGS in Makefile.am 
Since automake 1.13 INCLUDES is depricated and causes a warning
Inspired from similar patches by Alexander Huemer for other osmocom
projects.

Andreas Eversberg e6df0536ad Allow TRX 0..254 at VTY, even if less TRX are available 
Instead of limiting the number of TRX at VTY to the actual number of
supported TRX, VTY allows to configure any possible number of TRX. If a
TRX is configured, which is not supported by BTS model, an error message is
returned, which states that the given TRX is not supported.

Andreas Eversberg 7ba9bf5efa TRX: Do not send burst on IDLE channels at TRX != C0 
This is required, so the transceiver transmits no power.

Andreas Eversberg 770620b847 TRX: Set ciphering to an initial state when activating channel 
Handover and assignment may activate channels with ciphering already set,
so we need to tell scheduler to enable/disable ciphering and set the
correct cipher state.
