3 | The Hirschmann plug used for the power connection is called ''Hirschmann Leitungsdose CA 4 LD 09 ZS'' and has the product number |
||
4 | 13 | laforge | 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. |
5 | 9 | laforge | |
6 | The pin-out is as follows: |
||
7 | * GND: your shealding/earth line (PE), German:yellow/green wire |
||
8 | * 1: phase (L), German: Brown wire |
||
9 | * 2: not connected |
||
10 | * 3: neutral (N), German: Blue wire |
||

15 | == E1 Hardware interface == |
||
16 | 2 | laforge | |
17 | We are using a 120 Ohms balanced connection between the BS11 and a HFC-E1 card. |
||
18 | To configure the BS11 hardware correctly, you need to |
||
19 | * open the connection between pin 2 and 3 of the 4 jumpers below connector J01 |
||
20 | |||
21 | === Cable to RJ45 === |
||
22 | |||
23 | 12 | laforge | 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). |

26 | 1 | laforge | * Y02 PCM out (to BSC): RJ45 pin 1,2 |
27 | 7 | laforge | * Y03 PCM left open |

32 | 12 | laforge | the polarity of the two wires (4,5) or (1,2) inside one twinax plug does not matter, as the signals are symmetric anyway. |

34 | 15 | laforge | == Firmware / Minimal Configuration == |
35 | 1 | laforge | |
36 | 15 | laforge | The BS-11 runs firmware. The firmware consists of |
37 | * the SMU safety load (has to be loaded over RS232) |
||
38 | * the actual firmware images for the individual components inside the BS-11 |
||
39 | |||
40 | Firmware can be installed using either the proprietary 16-bit windows program LMT, or the [wiki:bs11_config] program which is part |
||
41 | of OpenBSC. |
||
42 | |||
43 | There is also a object database for the physical and functional objects inside the BTS. The object database consist of a set of attributes (and their values) for each object. Most parts of this database are stored in non-volatile memory of the BTS. |
||
44 | |||
45 | the so-called '''Minimal Configuration''' consists of those objects and attributes that need to be configured over the RS232 link |
||
46 | before an A-bis over E1 connection can be made. After the minimal configuration has been established, all other steps such as |
||
47 | software download and further configuration can be done over the E1 link. The minimal configuration needs a valid SMU safety load |
||
48 | installed. |

51 | 1 | laforge | |
52 | 15 | laforge | Please see the [wiki:bs11_config] page. |
53 | 10 | laforge | |
54 | 15 | laforge | The actual configuration of the objects is compiled-in. You can only change it by changing the source code. |
55 | |||
56 | 10 | laforge | === LMT === |
57 | |||
58 | 15 | laforge | If you're using LMT, you have to use the following procedure for firmware download and settings for the BTSM object: |
59 | 10 | laforge | |
60 | 11 | laforge | * Start LMT Release 04.21(!) and make sure the cable is connected. |
61 | * Set the serial port to the port you connected your serial console |
||
62 | cable to |
||
63 | * Logon as Administrator (Password is "admin") |
||
64 | * The factory configuration will not have any software installed |
||
65 | (Phase will show Software required) |
||
66 | * Select Software->Download SM Safety Load to load BTSBMC76.SWI from |
||
67 | the HS010876 directory |
||
68 | * After the download completes the BTS will restart and enter Phase |
||
69 | Wait Min Config |
||
70 | * Create an Object "LI", "GPSU", "ALCO", "CCLK", "BBSIG 0", with the |
||
71 | default config |
||
72 | * Create an Object "PA 0" with the following config: "GSM 0,03W(M3)" |
||
73 | This point is important to reduce the antenna power output! |
||
74 | * You will need a special password to activate "BBSIG 1" and "PA 1" |
||
75 | Configuration is analog to Channel 0 |
||
76 | * Create Object "EnvaBTSE 0" up to "EnvaBTSE 3" with the default |
||
77 | options |
||
78 | * As soon as all configuration options are set up the BTS will enter |
||
79 | the Maintenance phase and you will be able to load the main firmware |
||
80 | * Select "Download SM" in and select the file HS011106.SWL from the |
||
81 | HS011106 directory |
||
82 | * Grab a coffee and occupy yourself for about 45mins |
||
83 | * In BTSM Object set Timeslot no. to 1, Subslot no. to 64kbit/s |
||
84 | signalling and TEI to 25 |
