SOSM. System
of Operative-Search Measures
SOSM system developed for providing legal information monitoring for
operative-search possibility in the fixed and mobile networks. Protei Ltd specialists develop protocol-tester SOSM and SOSM-analyzer for technical support
of the national legislation requirement.
 Protocol-Tester TOR-4
The protocol-tester TOR-4 is integrated testing equipment for SOSM interface in switching nodes and exchanges of Russian PSTN.
The system presents intelligent simulator of SOSM CP (Control Point), equipped by monitoring
facilities for voice and control channels of the SOSM interface, possibilities for creating and
starting scenarios and load generating. The SOSM protocol-tester TOR-4 provides complex testing of SOSM facilities realized in an international exchange, exchange or PABX under
testing.
The system is designed in accordance with requirements of the documents of the last
versions, which regulate protocol parameters and functioning algorithm for SOSM equipment at PSTN of the Russian Federation:
- Technical requirements or the information interchange channels
between SOSM and CP for electronic exchanges;
- Technical requirements or the information interchange channels between
SOSM and CP for mobile networks;
- Standards of G.703, X.25, V.24 series;
Functionality
- Command generation;
- SOSM response monitoring;
- X.25 packages monitoring in two channels;
- Subscribers status monitoring;
- Statistic collection for events in the system (X.25 operating, SOSM functioning);
- Displaying statistical information in user comfortable form;
- Support till 8 E1;
- Voice channels monitoring;
- Recording of all voice information, coming through voice channels;
- Scenario implementation possibility;
- The work results keeping;
- Protocol-tester TOR-4 can be used at the stage of SOSM equipment development in electronic
exchanges, during their certificate,
factoryand field tests.
Structure scheme
The protocol-tester TOR-4 as a simulator of SOSM CP
(Control Point) can be connected to the testing station through E1 trunk (through 30 and 31 time slots).
For transmitting information by command channels and data using X.25 protocol (according to the document "Technical terms and conditions to the information
interchange links between SOSM and CP").
Software and hardware parts of the protocol-tester according to the functionality can
be divided into two modules: Sonde and Terminal.
Sonde module providing physical jointand SOSM interface network level.
Terminal Module response for control of the system and providing user interface of cooperation with SOSM module.
Technical characteristics of the Terminal and Sonde:
| Processor: Celeron |
Intel Celeron, 1 GHz and faster |
Hard Disk: |
40 Gb or more |

Encyclopedia on SOSM and X.25 protocol
The base of consulting documents is a set of documents intended to inform telecommunication
personnel about specified signaling protocols, their testing and converting.
The base also includes: regulating PSTN documents, information on exchanges,
which support corresponding signaling protocols, and additional literature list.
System requirements:
The base is realized at CD. The documents are made in PDF format (Portable Document
Format).
