2. പവർ കണക്ഷൻ: Connect the power adapter to the SBC's power input port and then plug it into a standard electrical outlet.
3. നെറ്റ്വർക്ക് കണക്ഷൻ: 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. പ്രാരംഭ കോൺഫിഗറേഷൻ ആക്സസ്:
   • Refer to the Quick Start Guide for the default IP address and login credentials.
   • ആക്സസ് ചെയ്യുക 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. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
