If you have just purchased a new BS-11, this guide will give you some basic instructions on how to proceed.
Check Package contentsPlease check the [wiki:BS11_Package_List Packing List] and see if you can find all the items in your two boxes.
If there is any doubt, please contact the openbsc mailing list and ask for help.
Please follow the instructions at [wiki:BS11_Configuration] to manufacture the power cable
Build E1 cablePlease follow the instructions at [wiki:BS11_Configuration] to manufacture the E1 cable
from RJ45 to the strange RADIALL twinax connectors
If you remove the connector cover (loosen three Philips screws), you will uncover the four E1 connectors,
as well as the RS232 ports. There are also four green jumpers at the side of the connector panel. The
factory default of those connectors is 75Ohms. You need to remove all of the four jumpers to switch to
120Ohms termination.
The Antenna needs to be attached to the BS11 main unit by the means of four screws. Screws are included in
a small plastic bag.
Connect the four RF antenna cables to the connectors of the BS-11. Their order is 1:1, i.e. leftmost plug into leftmost socket, etc.
Test the BS-11 status and configuration * connect the power plug to the BS-11 * connect the RS232 cable to J2 of the BS-11 (see photograph) * connect the RS232 cable to your PC * switch on the power switch of the BS-11 (the LED should light up green in 2-3 seconds) * start the bs11_config program to observe the boot process (see [wiki:bs11_config] for details) * you should observe the boot process like it is indicated at the [wiki:bs11_config] page * at the end of the process (10 minutes or so), you should have ''Phase 3 Normal'' and ''MBCCU0 Load'' and ''Abis-Link Restoring'' * MBCCU1 might be ''Load'' or ''No Load'', depending on whether TRX1 is activated or not * Once you are in "Phase 3 Normal", use ''bs11_config query'' to query the configuration * OML TEI must be 25 * OML E1 Timeslot must be 1 and the full 64kbps timeslot (no subslot)If you see any difference (i.e. not reaching ''Phase 3 Normal'' or no ''MBCCU0 Load'' or a different TEI/Timeslot configuration, please
contact the openbsc@lists.gnumonks.org mailinglist with the full details.
If everything is correct, you can proceed as follows:
