2. Connexió d'alimentació: Connect the power adapter to the SBC's power input port and then plug it into a standard electrical outlet.
3. Connexió de xarxa: Connect the SBC to your network using standard Ethernet cables. The rear panel features non-blocking gigabit switching data network ports. Typically, one port connects to the internal network (LAN) and another to the external network (WAN/SIP Trunk provider).
4. Initial Configuration Access:
   • Refer to the Quick Start Guide for the default IP address and login credentials.
   • Accedeix al web-based management interface from a computer connected to the same network segment as the SBC.
   • Log in using the default username and password. It is highly recommended to change these default credentials immediately for security purposes.
5. Basic Network Configuration: Configure the network interfaces (IP addresses, subnet masks, gateways, DNS servers) according to your network topology.
6. SIP Trunk and Routing Configuration: Set up your SIP trunks, routing rules, and security policies within the SBC's web interface. This includes defining inbound and outbound call routing, media transcoding profiles, and firewall rules.

5. Instruccions de funcionament

Once the Dinstar SBC300-20 is set up and configured, its operation is largely automated. Here are key operational aspects:

• Session Management: The SBC automatically manages SIP sessions, including call setup, teardown, and mid-call signaling. It ensures proper routing and handles NAT traversal.
• Media Transcoding: The device performs real-time media transcoding between different codecs (e.g., G.729, G.711) as required by the connected endpoints or SIP trunks.
• Seguretat: The SBC acts as a security gateway, protecting your internal network from external threats by inspecting SIP traffic, preventing denial-of-service (DoS) attacks, and enforcing security policies. It supports encrypted sessions via TLS and SRTP.
• Seguiment: Regularly access the web management interface to monitor system status, active sessions, resource utilization, and logs. This helps in identifying potential issues and ensuring optimal performance.
• Actualitzacions de firmware: Periodically check the Dinstar official website for firmware updates. Applying updates can improve performance, add new features, and address security vulnerabilities. Follow the provided instructions carefully when performing firmware upgrades.

• Control ambiental: Ensure the operating environment remains within specified temperature and humidity ranges. Keep the device free from dust and obstructions to ventilation.
• Auditories de seguretat: Periòdicament review your security configurations, including firewall rules, access control lists, and user credentials, to ensure they remain robust against evolving threats.
• Configuració de còpia de seguretat: Regularly back up your SBC's configuration settings. This allows for quick restoration in case of a system failure or misconfiguration.
• Gestió de cables: Ensure all network and power cables are securely connected and neatly organized to prevent accidental disconnections or damage.

7. Solució De Problemes

This section provides solutions to common issues you might encounter with your Dinstar SBC300-20.

7.1 Sense poder

• Comproveu el cable d'alimentació: Ensure the power adapter is securely connected to both the SBC and the electrical outlet.
• Verificar la presa de corrent: Test the electrical outlet with another device to confirm it is functional.
• Adaptador d'alimentació: If possible, test with a known good power adapter of the same specifications.

7.2 No es pot accedir Web Interfície

• Connexió de xarxa: Verify that your computer is connected to the same network as the SBC and that the Ethernet cables are properly connected.
• Adreça IP: Confirm the SBC's IP address. If unsure, you might need to reset the device to factory defaults (refer to the manual for specific instructions, if available, or contact support).
• Tallafoc: Ensure no local firewall on your computer or network is blocking access to the SBC's IP address or management port.
• Memòria cau del navegador: Esborra la memòria cau i les galetes del navegador o prova'n un altre web navegador.

7.3 Call Issues (No Audio, One-Way Audio, Call Drops)

• SIP Trunk Status: Check the status of your SIP trunks in the SBC's interface to ensure they are registered and active.
• Connectivitat de xarxa: Verify network connectivity between the SBC, your IP-PBX/endpoints, and the SIP service provider.
• Firewall/NAT: Ensure that all necessary ports are open on your network firewall and that NAT settings on the SBC are correctly configured.
• Codec Mismatch: Check if there's a codec mismatch. The SBC should transcode as configured, but verify the settings.
• Resource Utilization: Monitor the SBC's CPU and memory usage. High utilization might indicate an overload, especially if exceeding the 20 concurrent session recommendation.
