The abbreviation “SORM” is a complex of software and hardware designed for carrying out operational investigative measures in communication networks (system of operational investigative measures). SORM - 1 is a system that provides tracking of telephone conversations in landline and mobile networks. Similar systems exist in many countries, as they help law enforcement agencies in investigating crimes. In our country, the description of the means for creating such a solution, the procedure for their installation and processing of information are determined by law.

Currently, the main law that defines issues related to SORM - 1 is Order of the Ministry of Telecom and Mass Communications of the Russian Federation No. 268 of 2012. N New requirements for stationary equipment. For those companies that already have a system, the deadline for the transition to new equipment was set until the end of 2013.All organizations that are just starting out must use the system in accordance with the new requirements.

Order 268 defines the rules for fixed communications, that is, for landline telephones.For mobile communications, there are other regulations - their implementation is carried out by the operators themselves, while the heads of commercial organizations are concerned only with the new document.The new rules will help modernize system equipment more quickly and efficiently.

A more in-depth study of the rules and requirements. The new requirements are clearer.
The organization of data transmission channels can be done in two ways. The first involves the use of KI3, KI31 and the X 25 protocol. The second option involves the use of an Ethernet channel and the standard TCP / IP data transfer protocol. In this case, two data transmission channels are organized using two software ports. Every data packet transmitted over TCP/IP must begin with a command or message. The same message or command cannot be transmitted in different data packets. In both options for organizing data transmission channels, the permissible time for placing objects under control and removing them from control is set to up to 15 s.
For terminal and transit-end communication nodes, the number of controlled objects remained at the same level (1024), and for large transit nodes this figure increased to 2048. The maximum number of primary digital streams for transit and transit-terminal nodes also remained at the same level (8) , and for the terminal ones there are fewer (4 instead of 8). The criteria for the dependence of the maximum number of controlled objects on the characteristics of communication channels have been revised.
The new requirements regulate only fixed communication lines; message 12 has been added, which was previously only in the mobile system.
Previously, to place an object under control, it was possible to specify a zone number as a sign of a telephone number. In SORM - 1, according to the new rules, you must indicate a 10-digit federal number.
The data packets exclude fields that act as counters and indicate the conditional object number, call number and other data. These values are also used to indicate empty fields.

New commands and messages

The majority of commands retained their values and parameters. However, there are still a number of changes:

In commands numbered 5, 6, 10 and 12, it is no longer possible to specify a zone number attribute in the number attribute
In command No. 5, the conditional object number can now only have values in the range 0000H - FFFEF (previously, the value FFFFH could be used).

More changes occurred in the messages. Below are the changes for data link (DC) messages #1:

The maximum length of the “message content” section according to efficiency No. 1 is now no more than 245 bytes.
To make it easier to determine the protocol type when transmitting data, the last (10th) byte in the message header now has the value 02H (previously FFH).
An emergency code has been added for message No. 1.
For message No. 3, three designations for the status of the subscriber set have been added (03H - blocked, 07H - limited communication capabilities and FFH - information about the state of the set is unavailable).
The remaining changes concern messages 4 to 8, as well as message No. 12. They involve the elimination of typos, the introduction of new commands and values, as well as other innovations, which can be found in the text of the Order.

The list of messages for the second data transmission channel (KPD No. 2) has also changed. Here are the main ones:

In the call number, after the value FFFFH there is the value 0H
There have been changes to the message header structure
The “zone number” value has been removed from the number attribute values, and the GSM standard identifier attribute has been added instead

Installation and configuration of equipment

The implementation of SORM is a mandatory requirement for any company operating in Russia. The implementation of these requirements requires technical knowledge, in-house or
It is very difficult for an organization to install and configure equipment.

4.2. The format of message No. 1.4 corresponds to the standard format given in Appendix No. 10 to the Rules.

4.3. Message N 1.4 is generated and transmitted to the ORM control point when ordering, checking, or canceling communication services by the control object without establishing a connection. When using communication services during the connection process, message N 1.4 is transmitted to the OPM control point after the formation of message N 1.1 and before the formation of message N 1.3.

4.4. The “service description” field (bytes 33 to 35) contains the code of the service provided to the control object.

4.5. The 36th byte defines the "complementary code".

4.6. The remaining fields of message N 1.4 correspond to the contents of similar fields of message N 1.1, with the exception of cases when, before receiving message N 1.4, commands N 7, N 8 were used, which change the parameters of the control object. In this case the values change:

1) 10th byte of the message header - “sign of selection of the control object”:

A) when using command N 7, the values 02Н, 08Н, 20Н, 80Н (statistical control) change to the values 01Н or 03Н, 04Н or 0СН, 10Н or 30Н, 40Н or С0Н (full control), respectively;
b) when using commands N 8, the values 01Н or 03Н, 04Н or 0СН, 10Н or 30Н, 40Н or С0Н (full control) change to the values 02Н, 08Н, 20Н, 80Н (statistical control), respectively;

2) 25th and 26th bytes of the message content - “KSL-A number” and “KSL-B number”:

A) when using command N 7, the FFH values are changed to the numbers of the actually allocated KSL-A and KSL-B;
b) when using commands N 8, the numbers of the actually allocated KSL-A and KSL-B change to the FFH values;

3) 31st byte of the message content - “priority label”:

4) 32nd byte of the message content - “operation code” (KSL connection code):

A) when using command N 7, the value 01Н or FFH changes to the value 00Н;
b) when using commands N 8, the value 00Н changes to the value FFH.

5. Message No. 2.1 “Connecting the control trunk line”:

5.1. Message code N 2.1 is 51 N.

5.2. The format of message No. 2.1 corresponds to the standard format given in Appendix No. 10 to the Rules.

5.3. Message N 2.1 is transmitted as a result of executing command N 7.

1) 10th byte of the header - “object selection sign” - the values 02Н, 08Н, 20Н, 80Н (statistical control) change to the values 01Н or 03Н, 04Н or 0СН, 10Н or 30Н, 40Н or С0Н (full control), respectively;
2) the 25th and 26th bytes of the message content - “KSL-A number” and “KSL-B number” - the FFH value changes to the number of the actually allocated KSL-A and KSL-B;
3) 31st byte of the message content - “priority mark” - the value FFH or 02Н changes to the value 01Н (priority);
4) The 32nd byte of the message content - “operation code” (KSL connection code) - takes the value 00N - normal connection.

5.6. The contents of all fields of message N 2.1 in the absence of available CSLs in the group (under statistical control) correspond to the contents of similar fields of messages NN 1.1, 1.2 or N 1.4, depending on the moment of receipt of the N7 command - before or after the subscriber’s response, with the exception of the 32nd byte , the value of which is equal to FFH or 02Н for statistical control, changes to the value 01Н - “there are no available CSLs in the group”.

6. Message No. 2.2 “Release of control trunk line”:

6.1. Message code N 2.2 is 52Н.

6.2. The format of message No. 2.2 corresponds to the standard format given in Appendix No. 10 to the Rules.

6.3. Message N 2.2 is transmitted if the CSL is released for any reason.

6.5. The 32nd byte of the “contents” of message N 2.2 defines the “KSL release code” and takes the following meaning:

1) 01Н - by command No. 8;
2) 02Н - according to the priority of the control object;
3) 03Н - by priority, as a result of the actions of command No. 7;
4) 04Н - malfunction of station equipment;
5) 05Н - by command No. 6;
6) 06Н - by command No. 2.

7. Messages No. 2.3 “Test response message”:

7.1. Message code N 2.3 is 53Н.

7.2. The format of message N 2.3 is shown in Figure 1.

7.3. Message N 2.3 is transmitted over all existing KPD2 as a response to command N 14 received via any of the organized KPD1, no later than 200 ms from the moment command N 14 arrives at the station port.

7.4. Bytes from 5 to 12 of the message header (“call number”, “type of control object”, “conditional object number”, “sign of selection of control object”, “communication parameters” and “service phase code”) take the value FFH .
