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 (FIXME: which ones?) Database
Important database settings: * the database has to be downloaded from PC via E1 to BS11 * BCCH channel combination Type 5 oder 8 (including SDCCH for SMS) * TCH combination 0 oder 9 {{{
Cell config: Not hopping
No Concentric Cell = 0
Radiomeasgran =254
No Power Reduction = 0
Excessive distance =0 disabled
