# LCR GSM options #################

# Enable debugging of OpenBSC library. # Refer to OpenBSC project for debugging options. # By default, debugging is turned off. #debug DRLL:DCC:DMM:DRR:DRSL:DNM:DSMS:DMNCC:DMNSMS:DPAG:DMUX:DMEAS

# Two Loopback interfaces for audio transfer between OpenBSC and mISDN. # The first interface must provide B-channelis for each call mobile call. # The seond interface links them to LCR. # Use 30 B-channels unless you need more due to many TRXs. # -> Load with: "modprobe mISDN_l1loop pri=1 nchannel=30" # By default "mISDN_l1loop.1" and "mISDN_l1loop.2" is used. #interface-bsc mISDN_l1loop.1 #interface-lcr mISDN_l1loop.2

# Give openbsc.cnf config file # It will be located at /usr/local/lcr by default. config /opt/openbsc/src/openbsc.cfg

# Give database of Home Location Register (HLR) # HLR stores all subscribers. It will be used to grant access to the network. # It is an Sqlite3 database. Refer to OpenBSC project for handling. # The database is located at /usr/local/lcr by default. hlr /opt/openbsc/src/hlr.sqlite

# To keep layer 2 connection to BS11 when quitting, use this option. # It is only usefull for developing. TRX will stay on. # Also changes in frequency, mcc, mnc, lac while keeping layer 2 will cause # malefunction of BSC. # Warning: Keeping layer 2 link may prevent emergency calls. (See below) #keep-l2

# Shutdown on emergency calls: # This option will prevent a shutdown if an emergency call is received. In # case of an emergency, a mobile phone may log onto you GSM network and may # use it to set up an emergency call. # The received emergency call will have 'emergency' as dialed number. But this # number can't be dialed on PSTN networks without chaning. # If you disable shutdown, be sure to provide routing of emergency calls to # emergency facility. If you can't do that, don't touch it! #no-emergency-shutdown

# Write BTS-Link traffic to PCAP file. #pcapfile pcap

it seems that you hook twice on some interface. are you using asterisk also (in conjunction with chan_lcr)?

yes i'm using it also

regards,

andreas

p.s. please discuss this in the mailing list (see openbsc.gnumonks.org), so other users may have the same problems in the future. there are not many installations with LCR and openbsc.

hye Andreas,

i'm trying to get lcr working with openbsc and nanoBTS. To be able to come through this i have some questions:

First when i start lcr i have the following following error-informations:

** LCR Version 1.7

DB: Database initialized. DB: Database prepared. ERROR Port 1 already in use by LCR. You can't use a NT port multiple times. LCR 1.7 started, waiting for calls... ERROR (in main() line 447) LCR was stalling 2.25 seconds

but lcr seems to work actually. Is that the normal way it works or it there something wrong? I have nothing else running on LCR.

When i then try to set a call, lcr break out with the following information:

layer3_thread read socket error No space left on device

I don't known how many space is needed therefore, or in which folder or directory this space should be available. But the drive is quite empty. there is so much space available on it!

Also can you send me an example of a working dialplan and sip.conf to enable the routing of gsm calls??

thanks and best regards!!
