1.4. These TR must be provided regardless of what methods of information protection are used in the SDES.

1.5. These TTs must be provided when providing additional types of services to subscribers of the SDES.

1.6. These TTs must be provided for each individual subscriber, regardless of the type of connection to the DES network (individual or group).

2. COMPOSITION OF EQUIPMENT

The SORM must include:

• hardware and software that ensure the implementation of the requirements for SORM and are part of the remote control point (RCP) — APS SORM PU;
• hardware and software that ensure the implementation of the requirements for SORM and are part of the equipment of the node (nodes) of the DES network — APS SORM SDES;
• communication channel (communication lines and channel-forming equipment) that ensures the organization of communication between the APS SORM SDES and the APS SORM PU;

Note: Channel-forming equipment must be part of the APS SORM SDES equipment.

• software tools to ensure security and confidentiality of the SORM operation.

3. GENERAL REQUIREMENTS TO ORGANIZING SORM

3.1. The SORM SDES control should be carried out from the control center, through its interaction with the SORM SDES APS via communication channels that ensure the transmission of control commands from the control center to the SORM SDES APS and the transmission of information from the SORM SDES APS to the control center.

3.2. SORM must ensure the transfer to the control unit from the SORM SDES APS:

• on the readiness of the SORM SDES APS for operation;
• on the results of executing commands from the control unit;
• on unauthorized interference in the operation of the SORM SDES APS.

3.3. SORM must ensure the transfer to the control unit, upon request of the control unit operator, of the SDES user information base containing the following information about network subscribers:

• date of registration in the DES network;
• e-mail address;
• registration address;
• additional types of services provided, including inter-network roaming (and voice services).

3.4. For each individual user, SORM, upon command from the control center, must provide:

• removal of statistical information;
• removal of information (incoming and outgoing) belonging to specific users.

Note: This command may be documented by the communications operator.

3.5. The software must ensure the determination of:

• the subscriber's telephone number when the latter uses the public switched telephone network (if such a capability is available in this network) for the implementation of telematic services and data transmission;
• the subscriber's e-mail address when the latter uses other telecommunications networks for the implementation of telematic services and data transmission.

3.6. When collecting statistical information, SORM must ensure that the following information is transferred to the SORM SDES APS PU:

• working time on SDES;
• telephone number (switched telephone network) or network address (other communication network) from which access to SDES is carried out;
• network addresses to which access was carried out for receiving or transmitting information via SDES.

3.7. When collecting information, SORM must ensure that the following information is transferred to the SORM SDES APS PU:

• working time on SDES;
• telephone number (switched telephone network) or network address (other communication network) from which the access to the SDES was carried out;
• in real time, information transmitted via the SDES and belonging to specific users.

3.8. The SORM response time from the moment a command is entered from the control panel until confirmation of its execution is transmitted to the APS SORM SDES must be no more than 30 seconds (except for the command to interrupt the provision of communication services).

4. COMMUNICATION INTERFACE BETWEEN APS SORM SDES AND APS SORM PU.

4.1. Communication between SORM and PU must be carried out via a data transmission channel.

4.6. The protocol for exchanging digital information between SORM and the PU must comply with ITU-T recommendation X.25 (1995 edition) for the single-link LAPB procedure.

Note: When using information exchange protocols in the network that differ from ITU-T Recommendation X.25 (for example, TCP/IP), the information exchange protocol between SORM and the PU may differ from that specified in paragraph 4.6. in agreement with the FSB of Russia and the network administration.

4.7. The interface protocol between SORM and the PU (type of service information, interaction algorithm between SORM and the PU, organization of transmission of information messages) should be determined in the process of developing the SORM software in agreement with the FSB of Russia.

5. MONITORING THE PERFORMANCE OF SORM

5.1. When operating the hardware and software of the SORM, functional control of its operability must be provided against the background of the operation of the SDES equipment.

5.2. Information about the occurrence of malfunctions affecting the operation of the SORM SDES must be transmitted to the control center.

5.3. The serviceability of the information exchange channels between the SORM and the PU must be monitored. If the equipment of the information exchange channels between the PU and the SORM is damaged, data transmission must be stopped, a message about the damage must be sent to the operating personnel, and automatic switching to the backup channel must be ensured.
