| 4 | |||
| 5 | 1 | laforge | The MA10 is a full-length ISA card for PCs. |
| 6 | |||
| 7 | It contains multiple E1 transceivers and has the following external connections |
||
| 8 | 3 | laforge | * Handset (RJ-11 socket) |
| 9 | * RX0 (120 Ohms and 75 Ohms) |
||
| 10 | * RX1 (120 Ohms and 75 Ohms) |
||
| 11 | * TX1 (120 Ohms and 75 Ohms) |

| 15 | |||
| 16 | |||
| 17 | 1 | laforge | As we use the BS11 in 120 Ohms symmetric configuration, we also use the 120 Ohms symmetric ports of the MA10. |
| 18 | |||
| 19 | The 120 Ohms symmetric ports of the MA10 are all LEMO type FGG.0B.302.CLAD42Z |

| 24 | |||
| 25 | |||
| 26 | 1 | laforge | There are a number of different software packages available for the MA10 |

| 37 | h3. Abis Monitor |
||
| 38 | |||
| 39 | |||
| 40 | 1 | laforge | The Abis Monitor allows you to monitor an Abis link. You connect the two RX ports to the E1 link and can thus sniff |
| 41 | the bidirectional communication between BSC and BTS. |
||
| 42 | |||
| 43 | There are commercial extensions (today they would probably be called plug-ins) that extend the protocol parser |
||
| 44 | with vendor-specific commands, such as the Siemens O&M layer. |
||
| 45 | |||
| 46 | |||
| 47 | 3 | laforge | h3. Abis Simulator |
| 48 | |||
| 49 | |||
| 50 | 1 | laforge | This is a complete simulator for the BSC side of the Abis link. Using the Abis simulator and a BTS, you can |
| 51 | emulate a GSM network. |
||
| 52 | |||
| 53 | In this mode, the MA10 assumes an active role and thus you need to connect RX0 and TX0 with the BTS. |
||

| 56 | h3. Restrictions |
||
| 57 | |||
| 58 | 2 | laforge | |
| 59 | Audio output/input with headset is not supported by any of the "AbisSim" releases. |
||
| 60 | Only echo loop is supported on traffic channels. |
||
| 61 | This means that using a mobile phone connected to BTS controlled by the MA10 |
||
| 62 | can only loop back the audio input form this mobile. |
