Harald Welte ed607f475f increae the RACH quality threshold to 5dB C/I 2011-07-07 18:17:31 +02:00
Harald Welte be598e3afd RSL: Send fake CIPHERING MODE COMPLETE 
we do this as a hack as long as the MSC assumes the BTS supports
A5, but the L1 really doesn't support it yet.

Harald Welte 540410c123 RSL: implement RSL ENCR CMD, feed L3_INFO to LAPDm 
This is not full encrpytion support, the bts-model part still
needs to detect the ENCR CMD when de-queueing from LAPDm and enable
the de-ciphering, detect the arrival of the first encrypted frame,
etc, enable en-ciphering, ...

Harald Welte 39eadbbb17 sysmbts L1 if: implement 'dead DSP L1 detection' 
when we activate the SCH in the DSP, we start a 5-second timer.  If
we ever do not receive any MPH-TIME.ind primitives from L1 within
that time frame, we stop the process (and will be re-spawned)

Harald Welte 547b1d1916 l1_if: send EMPTY-FRAME.req instead of fill frame on TCH/F + FACCH 2011-07-05 16:15:26 +02:00
Harald Welte 1920738840 L1/OML: De-activate L1 SAPIs in opposite order of activation 
L1 wants TCH to be activated before FACCH, and it wants FACCH
to be de-activated before TCH.  By iterating the array in iverse
order, we ensure this.

Harald Welte f788d79411 sysmobts-remote: Remove hard-coded BTS IP address 
The BTS IP address can now be specified by the L1FWD_BTS_HOST env
variable.

Option parsing would not have been that easy to integrate without
touching the main program...

Harald Welte f15cef94f7 fix various compiler warnings 2011-07-01 18:22:01 +02:00
Harald Welte 9fa0cce100 fix BTS initialization order 
The sequence is as follows:

0) start osmo-bts
1) start connection attempts to BTS
2) issue L1-RESET.req
3) receive L1-RESET.conf
4) issue RF-ACTIVATE.req
5) receive RF-ACTIVATE.conf
6) receive attributes for TRX
7) receive opstart for TRX
8) issue MPH-INIT.req
[...]

The important point here is: We don't want the BSC to set TRX attributes or do
TRX opstart before our RF related hardware is initialized.

Harald Welte 0f827275d7 sysmo-bts: Ignore OPSTART on the TRX until we have seen SET ATTR 2011-07-01 16:02:19 +02:00

Harald Welte b849684181 deactivate RF + exit when the Abis link is gone

Harald Welte 2bc0e10fa1 RSL/LAPDM: make sure we do lapdm_channel_reset()

clean start for the next user of the same lapdm channel.

Harald Welte b9919bd2a6 Fix support of SDCCH4 
In SDCCH4, we use lchan number 0...3 for the SDCCH/SACCH, and
we statically use lchan[4] as the dummy for activating the CCCH
L1 SAPIs.

In order to make combined and non-combined CCCH orthogonal, we simply
also use lchan[4] in that case.  On a 'pure' CCCH, therefore lchan
0..3 are unused and 4 is the actual CCCH.

Harald Welte a7d6261108 sysmocom L1: raise the threshold for ignored RACH bursts 
the RACH burst detection in the physical layer is appranetly providing many
false positives, and we need to raise the bar a bit in order to not allocate
channels in a useless way...

bugs:
* L3 INFO content seems to have some offset
* is_sub is not set anywhere
* measurement periods might have up/downlink offset
