== Power Connection ==
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 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 attached at the bottom of this page.
== 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).
* 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
== Configuration of BTSM Object ==
* BS11 requires PCM30CRC4 64kBit/s no Subslots
* OM Layer on Timeslot 1
* TEI for OM Layer default Siemens is 25 (but configurable in BS11 [wiki:LMT])
* the following parameters are not configurable
* RSL Layer on Timeslot 1, too
* TEI for RSL is fixed in Siemens equipment
* TEI = 0 für TRX0
* TEI = 1 für TRX1
* Attention: if you select OM Layer TEI 0 oder 1, RSL can no longer be brought up
* Timeslots for TCHs
* TRX0: TS2 und TS3
* TRX1: TS4 und TS5
== E1 interface ==
LI Objekt: Line MULTIDROP
Impedance 120 Ohm balanced to connect to HFC-E1 board
Additionally you will need to change some jumpers on the connector board
of BS11:
* dip-switch SW3:
* 1-4: off
* 5-8: on
* TB01: no jumper
* TB02: no jumper
* TB03: no jumper
* TB04: no jumper
SW3 is the dip-switch underneath the connector board
TB0* are the four jumpers on the left hand side of the connector board.
== Database ==
Important database settings:
* the database has to be downloaded from PC via E1 to BS11
* BCCH channel combination Type 5 or 8 (including SDCCH for SMS)
* TCH combination 0 or 9
