hello list,
i'd like you to go with me thru my setup of 2 bs11 and verify it. it looks like this:
E1 E1
PC------BTS0------BTS1
let's begin with the bs11_config outputs
bts0:
LMT LOGON: ACK
PHASE: 3 Normal MBCCU0: Load MBCCU1: No Load Abis-link: Restoring
BS11 ATTRIBUTES:
BS-11 ESN PCB Serial Number: 001104
BS-11 ESN Hardware Code Number: 135-2044/03.07
BS-11 ESN Firmware Code Number: 135-2044/03.07
PLL Set Value=1006, Work Value=1038
SITE MANAGER ATTRIBUTES:
E1 Channel: Port=0 Timeslot=1 (Full Slot)
TEI: 25
BS11 Line Interface ATTRIBUTES:
PLL Mode: Standalone
BS11 CCLK ATTRIBUTES:
CCLK Accuracy: High (1)
CCLK Type=0
BS11 Power Amplifier 0 ATTRIBUTES:
TRX Power: 30mW (GSM)
BPORT0 ATTRIBUTES:
Line Configuration: Multi-Drop (1)
BPORT1 ATTRIBUTES:
Line Configuration: Multi-Drop (1)
LMT LOGOFF: ACK
and that's bts1:
LMT LOGON: ACK
PHASE: 3 Normal MBCCU0: Load MBCCU1: No Load Abis-link: Restoring
BS11 ATTRIBUTES:
BS-11 ESN PCB Serial Number: 001112
BS-11 ESN Hardware Code Number: 135-2044/03.03
BS-11 ESN Firmware Code Number: 135-2044/03.03
PLL Set Value=1073, Work Value=1073
SITE MANAGER ATTRIBUTES:
E1 Channel: Port=1 Timeslot=17 (Full Slot)
TEI: 25
BS11 Line Interface ATTRIBUTES:
PLL Mode: Standalone
BS11 CCLK ATTRIBUTES:
CCLK Accuracy: High (1)
CCLK Type=0
BS11 Power Amplifier 0 ATTRIBUTES:
TRX Power: 30mW (GSM)
BPORT0 ATTRIBUTES:
Line Configuration: Star (0)
BPORT1 GET ATTR NACK <--- do i have to worry about his?
LMT LOGOFF: ACK
here we go with openbsc.cfg. i use only trx0 of each bts. don't ask why i did
something like this or like that, i just adapted the openbsc.cfg-file from the packet to
my timeslots configured

max_power_red 0
rsl e1 line 0 timeslot 1 sub-slot full <-- the same e1 timeslot for oml is used
here for the ccch.
rsl e1 tei 1 | correct?
timeslot 0 | i'd say weird

oml e1 line 0 timeslot 17 sub-slot full <-- harald told me line has to be 0, but i
dont understand why. i configured 2 fragments on the misdn driver, with d-channel on ts 1
and 17, the rest b-channels. each fragment is a device,right? (0 and 1). Each device
corresponds to a port in bs11_config and a line here, right ?
oml e1 tei 25 <-- here again: all oml e1 teis identical?
trx 0
arfcn 122
max_power_red 0
rsl e1 line 0 timeslot 17 sub-slot full
rsl e1 tei 2
timeslot 0
phys_chan_config CCCH+SDCCH4 <--here we go with line(=port=id) 1, since
fragment 2 starts ad device id 1 on e1 ts 17 as d-channel
e1 line 1 timeslot 17 sub-slot full
timeslot 1
phys_chan_config SDCCH8
e1 line 1 timeslot 18 sub-slot 1
timeslot 2
phys_chan_config TCH/F
e1 line 1 timeslot 18 sub-slot 2

phys_chan_config TCH/F
e1 line 1 timeslot 19 sub-slot 2
timeslot 7
phys_chan_config TCH/F
e1 line 1 timeslot 19 sub-slot 3
and for the final: the output of bsc_hack during start:
2 devices found
id: 0
Dprotocols: 00000018
Bprotocols: 0000000e
protocol: 4
nrbchan: 14
name: hfc-e1.1-1
activate bchan
activate bchan
DB: Database initialized.
DB: Database prepared.
since line 1 isnt used for bts1 oml, only device id 0 with d-channel on ts 1 is activated.
but im quite sure this is a mistake, i need 2 devices for 2 bts. right?
this config dont work at all. bts1 not recognised, bts0 is recognised but cant handle
calls. the handys are callable and ring, but no data is transmitted.
please give me as much feedback as possible
mni tnx
T.
