| 3 | We are using a 120 Ohms balanced connection between the BS11 and a HFC-E1 card. |
||
| 4 | To configure the BS11 hardware correctly, you need to |
||
| 5 | * open the connection between pin 2 and 3 of the 4 jumpers below connector J01 |
||
| 6 | |||
| 7 | === Cable to RJ45 === |
||
| 8 | |||
| 9 | 3 | laforge | * left Y01 PCM in (from BSC): RJ45 pin 4,5 |
| 10 | * Y02 PCM out (to BSC): RJ45 pin 1,2 |
||
| 11 | * Y03 PCM connected 1:1 with Y04 PCM |
||

| 13 | 1 | laforge | == Configuration of BTSM Object == |
| 14 | |||
| 15 | * BS11 requires PCM30CRC4 64kBit/s no Subslots |
||
| 16 | * OM Layer on Timeslot 1 |
||
| 17 | * TEI for OM Layer default Siemens is 25 (but configurable in BS11 [wiki:LMT]) |
||
| 18 | |||
| 19 | * the following parameters are not configurable |
||
| 20 | * RSL Layer on Timeslot 1, too |
||
| 21 | * TEI for RSL is fixed in Siemens equipment |
||
| 22 | * TEI = 0 für TRX0 |
||
| 23 | * TEI = 1 für TRX1 |
||
| 24 | * Attention: if you select OM Layer TEI 0 oder 1, RSL can no longer be brought up |
||
| 25 | |||
| 26 | * Timeslots for TCHs |
||
| 27 | * TRX0: TS2 und TS3 |
||
| 28 | * TRX1: TS4 und TS5 |

| 35 | Additionally you will need to change some jumpers on the connector board |
||
| 36 | 4 | laforge | of BS11: |
| 37 | 5 | laforge | * dip-switch SW3: |
| 38 | * 1-4: off |
||
| 39 | * 5-8: on |
||
| 40 | * TB01: no jumper |
||
| 41 | * TB02: no jumper |
||
| 42 | * TB03: no jumper |
||
| 43 | * TB04: no jumper |
||
| 44 | 4 | laforge | |
| 45 | SW3 is the dip-switch underneath the connector board |
||
| 46 | TB0* are the four jumpers on the left hand side of the connector board. |

| 52 | * the database has to be downloaded from PC via E1 to BS11 |
||

| 55 | * BCCH channel combination Type 5 oder 8 (including SDCCH for SMS) |
||
| 56 | * TCH combination 0 oder 9 |
