Hello, Now I can configure the bs11 using the bs11_config. Everything worked fine and I obtained this on bs11_config query : LMT LOGON: ACK PHASE: 3 Normal MBCCU0: Load MBCCU1: No Load Abis-link: Restoring BS11 ATTRIBUTES: BS-11 ESN PCB Serial Number: 001073 BS-11 ESN Hardware Code Number: 135-2044/03.03 BS-11 ESN Firmware Code Number: 135-2044/03.03 PLL Set Value=1053, Work Value=1053 SITE MANAGER ATTRIBUTES: E1 Channel: Port=0 Timeslot=1 (Full Slot) TEI: 25 BS11 Line Interface ATTRIBUTES: PLL Mode: Standalone BS11 Power Amplifier 0 ATTRIBUTES: TRX Power: 30mW (GSM) Mon May 25 16:01:12 2009 <0020> abis_nm.c:811 GET ATTRIBUTE NACK LMT LOGOFF: ACK I didn't doanwload: -the SAFETY LOAD software -the BTS software Is it necessary since I can reach Phase 3 and since I can see the Firmware Code Number? I continued to follow the "getting started" tutorial untill the E1 Link and I have the following problem when launching bsc_hack : ./bsc_hack -f 123 --debug=DRLL:DCC:DMM:DRR:DRSL:DNM:DMI:DMUX:DPAG:DRLL:DSMS DB: Database initialized.

I only changed the Dip switches for 120 ohms. I can see 2 steady red led (which means i am in NT mode, TE mode deactivate). Both green leds are off (is it normal?). /* HFC-E1 OEM */ + /* 2 red blinking: NT mode deactivate + * 2 red steady: TE mode deactivate + * left green: L1 active + * left red: frame sync, but no L1 + * right green: L2 active + */ Anyone? Thanks in advance! Best regards Eric Cathelinaud
