no need to buy hirschmann plug
The Hirschmann plug used for the power connection is called ''Hirschmann Leitungsdose CA 4 LD 09 ZS'' and has the product number
932 362-100. The BS-11 includes one such plug, so unless you loose it, damage it or want multiple power cables, there is no need in obtaining this plug separately.
The pin-out is as follows: * GND: your shealding/earth line (PE), German:yellow/green wire * 1: phase (L), German: Brown wire * 2: not connected * 3: neutral (N), German: Blue wire
Please refer to the photograph of a fully wired plug:

We are using a 120 Ohms balanced connection between the BS11 and a HFC-E1 card.
To configure the BS11 hardware correctly, you need to
* open the connection between pin 2 and 3 of the 4 jumpers below connector J01
=== Cable to RJ45 ===
The E1 interface[s] of the BS-11 are on some strange BNC-related twinax plugs called "BR2" (Radiall product # 605006000), you can find the PDF data sheet of the connectors at [http://radiall.applixia.net/catalogue/resource?path=PRODUCT/PDF/TDS/coaxialconnectors/R605006000EN.pdf Radiall]. There are four such plugs included in the BS-11 package. If you need more, you can buy them online from [http://webradiall.applixia.net/buyonline?PN=R605006000&LANG=en&SUP=FARNELL this link] (which for Germany results in a hyperlink to [http://de.farnell.com/jsp/displayProduct.jsp?sku=4196995 this page of the Farnell webshop] where they cost EUR 16.51 each).
- left Y01 PCM in (from BSC): RJ45 pin 4,5
- Y02 PCM out (to BSC): RJ45 pin 1,2
- Y03 PCM left open
- Y04 PCM left open
the polarity of the two wires (4,5) or (1,2) inside one twinax plug does not matter, as the signals are symmetric anyway.
Configuration of BTSM Object=== bs11_config ===
If you're using [wiki:bs11_config], then the configuration is compiled-in (thus automatically
correct) and you can only change it by changing the source code.
=== LMT ===
If you're using LMT, you have to use the following settings for the BTSM object:
- Start LMT Release 04.21(!) and make sure the cable is connected.
- Set the serial port to the port you connected your serial console
cable to - Logon as Administrator (Password is "admin")
- The factory configuration will not have any software installed
(Phase will show Software required) - Select Software->Download SM Safety Load to load BTSBMC76.SWI from
the HS010876 directory - After the download completes the BTS will restart and enter Phase
Wait Min Config - Create an Object "LI", "GPSU", "ALCO", "CCLK", "BBSIG 0", with the
default config - Create an Object "PA 0" with the following config: "GSM 0,03W(M3)"
This point is important to reduce the antenna power output! - You will need a special password to activate "BBSIG 1" and "PA 1"
Configuration is analog to Channel 0 - Create Object "EnvaBTSE 0" up to "EnvaBTSE 3" with the default
options - As soon as all configuration options are set up the BTS will enter
the Maintenance phase and you will be able to load the main firmware - Select "Download SM" in and select the file HS011106.SWL from the
HS011106 directory - Grab a coffee and occupy yourself for about 45mins
- In BTSM Object set Timeslot no. to 1, Subslot no. to 64kbit/s
signalling and TEI to 25
