Deployment workflow
From analog endpoint to secure SIP service.
The 4102S sits at the analog edge and converts existing voice, fax or modem endpoints into managed SIP-based communication.
1. Analog DeviceTelephone, fax, modem or legacy PBX analog line.
2. FXS PortConnect to one of the two RJ-11 FXS interfaces.
3. 4102S ATAProcesses voice, DTMF, fax, routing and line signaling.
4. Secure IPUses SIP/TLS, SRTP, QoS, VLAN, NAT and firewall services.
5. SIP PlatformConnects to cloud telephony, IP-PBX, UC, softswitch or operator core.
Engineering note: For installation safety, do not connect FXS, LAN or WAN connectors directly to the PSTN or unintended exposed/out-of-plant applications. Use the correct cabling, power source and service-personnel installation practices for the deployment environment.
