5 | The Hirschmann plug used for the power connection is called _Hirschmann Leitungsdose CA 4 LD 09 ZS_ and has the product number |
||
6 | 1 | 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. |

8 | The pin-out is as follows: |
||
9 | 17 | laforge | * GND: your shealding/earth line (PE), German:yellow/green wire |
10 | * 1: phase (L), German: Brown wire |
||
11 | * 2: not connected |
||
12 | * 3: neutral (N), German: Blue wire |

19 | |||
20 | |||
21 | 1 | laforge | We are using a 120 Ohms balanced connection between the BS11 and a HFC-E1 card. |
22 | To configure the BS11 hardware correctly, you need to |
||
23 | 17 | laforge | * open the connection between pin 2 and 3 of the 4 jumpers below connector J01 |

29 | 17 | 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 "Radiall":http://radiall.applixia.net/catalogue/resource?path=PRODUCT/PDF/TDS/coaxialconnectors/R605006000EN.pdf. There are four such plugs included in the BS-11 package. If you need more, you can buy them online from "this link":http://webradiall.applixia.net/buyonline?PN=R605006000&LANG=en&SUP=FARNELL (which for Germany results in a hyperlink to "this page of the Farnell webshop":http://de.farnell.com/jsp/displayProduct.jsp?sku=4196995 where they cost EUR 16.51 each). |

38 | 1 | 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. |

41 | 17 | laforge | h2. Firmware / Minimal Configuration |
42 | |||
43 | |||
44 | 1 | laforge | The BS-11 runs firmware. The firmware consists of |
45 | 17 | laforge | * the SMU safety load (has to be loaded over RS232) |
46 | * the actual firmware images for the individual components inside the BS-11 |
||
47 | 1 | laforge | |
48 | 17 | laforge | Firmware can be installed using either the proprietary 16-bit windows program LMT, or the [[bs11_config]] program which is part |
49 | of [[OpenBSC]]. |
||
50 | 1 | laforge | |
51 | 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. |
||
52 | |||
53 | 17 | laforge | the so-called *Minimal Configuration* consists of those objects and attributes that need to be configured over the RS232 link |
54 | 1 | laforge | before an A-bis over E1 connection can be made. After the minimal configuration has been established, all other steps such as |
55 | software download and further configuration can be done over the E1 link. The minimal configuration needs a valid SMU safety load |
||
56 | installed. |

61 | 17 | laforge | |
62 | Please see the [[bs11_config]] page. |
||
63 | |||
64 | 15 | laforge | The actual configuration of the objects is compiled-in. You can only change it by changing the source code. |

67 | 17 | laforge | h3. LMT |
68 | |||
69 | |||
70 | 11 | laforge | If you're using LMT, you have to use the following procedure for firmware download and settings for the BTSM object: |
71 | |||
72 | 17 | laforge | * Start LMT Release 04.21(!) and make sure the cable is connected. |
73 | * Set the serial port to the port you connected your serial console |
||
74 | 11 | laforge | cable to |
75 | 17 | laforge | * Logon as Administrator (Password is "admin") |
76 | * The factory configuration will not have any software installed |
||
77 | 11 | laforge | (Phase will show Software required) |
78 | 17 | laforge | * Select Software->Download SM Safety Load to load BTSBMC76.SWI from |
79 | 11 | laforge | the HS010876 directory |
80 | 17 | laforge | * After the download completes the BTS will restart and enter Phase |
81 | 11 | laforge | Wait Min Config |
82 | 17 | laforge | * Create an Object "LI", "GPSU", "ALCO", "CCLK", "BBSIG 0", with the |
83 | 11 | laforge | default config |
84 | 17 | laforge | * Create an Object "PA 0" with the following config: "GSM 0,03W(M3)" |
85 | 11 | laforge | This point is important to reduce the antenna power output! |
86 | 17 | laforge | * You will need a special password to activate "BBSIG 1" and "PA 1" |
87 | 11 | laforge | Configuration is analog to Channel 0 |
88 | 17 | laforge | * Create Object "EnvaBTSE 0" up to "EnvaBTSE 3" with the default |
89 | 11 | laforge | options |
90 | 17 | laforge | * As soon as all configuration options are set up the BTS will enter |
91 | 1 | laforge | the Maintenance phase and you will be able to load the main firmware |
92 | 17 | laforge | * Select "Download SM" in and select the file HS011106.SWL from the |
93 | 1 | laforge | HS011106 directory |
94 | 17 | laforge | * Grab a coffee and occupy yourself for about 45mins |
95 | * In BTSM Object set Timeslot no. to 1, Subslot no. to 64kbit/s |
