3 | The MA10 is a full-length ISA card for PCs. |
||
4 | |||
5 | It contains multiple E1 transceivers and has the following external connections |
||
6 | * Handset (RJ-11 socket) |
||
7 | * RX0 (120 Ohms and 75 Ohms) |
||
8 | * RX1 (120 Ohms and 75 Ohms) |
||
9 | * TX1 (120 Ohms and 75 Ohms) |
||

11 | === Cabling === |
||
12 | |||
13 | As we use the BS11 in 120 Ohms symmetric configuration, we also use the 120 Ohms symmetric ports of the MA10. |
||
14 | |||
15 | The 120 Ohms symmetric ports of the MA10 are all LEMO type FGG.0B.302.CLAD42Z |
||
16 | |||

18 | == MA10 Software == |
||
19 | |||
20 | There are a number of different software packages available for the MA10 |
||
21 | |||
22 | === MA10 Control === |
||
23 | |||
24 | === BERT === |
||
25 | |||
26 | === Abis Monitor === |
||
27 | |||
28 | The Abis Monitor allows you to monitor an Abis link. You connect the two RX ports to the E1 link and can thus sniff |
||
29 | the bidirectional communication between BSC and BTS. |
||
30 | |||
31 | There are commercial extensions (today they would probably be called plug-ins) that extend the protocol parser |
||
32 | with vendor-specific commands, such as the Siemens O&M layer. |
||
33 | |||
34 | === Abis Simulator === |
||
35 | |||
36 | This is a complete simulator for the BSC side of the Abis link. Using the Abis simulator and a BTS, you can |
||
37 | emulate a GSM network. |
||
38 | |||
39 | In this mode, the MA10 assumes an active role and thus you need to connect RX0 and TX0 with the BTS. |

41 | === Restrictions === |
||
42 | |||
43 | Audio output/input with headset is not supported by any of the "AbisSim" releases. |
||
44 | Only echo loop is supported on traffic channels. |
||
45 | This means that using a mobile phone connected to BTS controlled by the MA10 |
||
46 | can only loop back the audio input form this mobile. |
