hello
im still trying to make 2 bts work in multidrop mode. bts0, the one on
the pc, tells that:
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
this bs11 works pretty well as single config.
but bts1 tells that:
LMT LOGON: ACK
PHASE: 3 Normal MBCCU0: No Load MBCCU1: Load
Abis-link: Restoring
BS11 ATTRIBUTES:
BS-11 ESN PCB Serial Number: 001111
BS-11 ESN Hardware Code Number: 135-2044/03.03
BS-11 ESN Firmware Code Number: 135-2044/03.03
PLL Set Value=1042, Work Value=1221
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: Medium (0)
CCLK Type=0
BS11 Power Amplifier 0 ATTRIBUTES:
TRX Power: 2W (GSM)
BPORT0 ATTRIBUTES:
Line Configuration: Star (0)
BPORT1 GET ATTR NACK
LMT LOGOFF: ACK
as you can see, i configured the 2nd bs11 with ts 17 on port 1,
according the bmask and dmask settings(sorry for that yesterday, but
sometimes there are so many trees you dont see the forest - german
saying), and bsc_hack starts now without problems, but bootstrapping is
only on bts0, bts1 isnt recognised.
when i connect bts1 to the pc and run it in single mode(with line 1
timeslot 17 settings in openbsc.cfg), it is recogised with
bootstrapping, but dont function. it isnt seen by any handy. i put 2
attachments in the mail, hope they arent dropped
could the different pll and work values be the reason?
is the BPORT1 GET ATTR NACK from bts1 a possible reason?
what about the strange messages seen in the bts1_err.jpg?

Thomas,
I really don't understand why this is giving you such a hard time.
Was very easy and simple for the HAR2009 setup.
I assume your setup is like this:
E1 E1
PC------BTS0------BTS1
* the PC connects to BTS0 Port0
* BTS0 Port1 connects to BTS1 Port0
As a consequence, it is logical that:
1) BTS0 must have two BPORT (0+1) objects, both in multi-drop mode
2) BTS1 must have one BPORT (0) object, in 'star' configuration
3) both BTS need to run the site manager on Port0, as this is the
port that faces towards the BSC
4) OML of each BTS must be on a serparate timeslot (like 1 + 17)
5) timslot mapping of hfcmulti.ko and BTS0 and BTS1 must match, e.g.
have D channels on 1 and 17.
