E1 Hardware interface

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] and 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).

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.

  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
