  • Page 23: General Guidelines For Gateway Operation

    GENERAL GUIDELINES FOR GATEWAY OPERATION The easiest way to configure and monitor the device is to use the web interface, so it is highly recommended. To prevent unauthorised access to the device, it is recommended to change the password for telnet and console access (default username: admin, password: rootpasswd) and the administrator password for the web interface.
  • Page 24: Device Configuration

    DEVICE CONFIGURATION The device provides 4 connection options: web interface, the Telnet protocol, SSH, or RS-232 cable connection (for access via RS-232, SSH, or Telnet, use CLI). All settings will take effect without gateway restart. To save configuration changes into the non- volatile memory, use the Service/Save Configuration into Flash menu in the web configurator or the COPY RUNNING_TO_STARTUP command in CLI.

CORRELATION BETWEEN ROUTING, SUBSCRIBERS, AND SIGNAL LINK PARAMETERS An incoming call from an IP or TDM channel arrives to the incoming interface, then the call further routing is determined by a trunk group (TG) using the RADIUS protocol (if applicable). The TG performs number modifications for incoming communication.

    APPENDIX E. GUIDELINES FOR SMG OPERATION IN A PUBLIC NETWORK SMG operation in a public network requires to take all security measures in order to avoid the device password brute forcing, DoS (DDoS) attacks, and other intrusive actions which may lead to unstable operation, subscriber data theft, attempts to perform calls at the expense of other subscribers, and consequently to damages to the service provider as well as subscribers.
  • Page 189: Appendix F. Device Interaction With Monitoring Systems

    10 APPENDIX F. DEVICE INTERACTION WITH MONITORING SYSTEMS To enable real-time fault monitoring for the device, configure device interaction with a monitoring system. Absence of faults means device normal operation; when a fault event occurs, the normal state turns to the alarm state, when all the current faults are resolved, the normal operation state is restored.
  • Page 190 To configure LOS and AIS fault indication for an E1 stream, check the Alarm Indication checkbox. To configure RAI fault indication, check the Remote Alarm Indication checkbox. To configure slips indication for a stream, check the SLIP Indication checkbox and configure the SLIP detection timer.
  • Page 191 To perform the configuration, check the Enable SNMP checkbox. 4) To configure SNMP trap output, use the Network Services/SNMP menu (section 4.1.9.2 SNMP Traps Settings). To perform the configuration, specify an SNMP message type (TRAPv1, TRAPv2, INFORM), a password (Community), an IP address and an SNMP trap recipient port. When the configuration is set up and applied, restart the SNMP agent by clicking the Restart SNMPd button.

    11 APPENDIX G: CONFIGURATION OF E1 CHANNELS TRANSIT THROUGH A SEMIPERMANENT CONNECTION Work principle The channels for transit through a SIP interface are selected from E1 stream which is connected to SMG. SMG transmit request via SIP interface for establishment of connections with remote SMG. Remote SMG receives the request and connects voice tract with appropriate E1 channel.
  • Page 193 On the receiving SMG the following actions must be performed: 1. Create a new interface in 'Routing -> SIP interfaces' section: 1.1. Set 'Transit E1' mode on the interface; 1.2. Set IP address of the remote side; 1.3. Set signalling destination port on the remote side; 1.4.
