Remote Connectivity Solutions PSTN, ISDN, GPRS, EDGE, 3G, ADSL, LAN Which connectivity to use ? A solution based approach > Remote Connectivity Solutions 2 markets 1 2 Machine Builders Infrastructure/Utilities > Remote Connectivity Solutions 2 different needs 1 2 Connection on purpose: 1. Connection temporary oriented 2. Simplex communication: machine/RTU ->user 3. Or… full duplex (bi-directional) communication: user-machine/RTU-user Or persistent connection 1. Duplex communication 2. And asset/site-to-site extranet > Remote Connectivity Solutions 2 different technologies 1 2 Old style modem like: dial-up (Point-to-Point connections over telephone network) Embedded PSTN, ISDN or GSM data modem Purely IP though Internet network Embedded PSTN, ISDN, GPRS, EDGE, 3G, ADSL modem or connection through LAN > Remote Connectivity Solutions Connection direction Remote Connectivity Matrix Duplex, Remote Access Simplex, From RTU * Temporary, on purpose Persistent Connection duration RTU = Remote Terminal Unit = eWON > Remote Connectivity Solutions Connection direction Solutions for Machine Builders Remote Maintenance= Duplex, Remote Access 1. 2. 3.

Technology review 2. Internet Service Provider (ISP) on the eWON side should provide Public IP address and Firewall (ISP) should be transparent to the VPN connection Internet IP source VPN Tunnel Service Provider IP dest (public IP) > Remote Connectivity Solutions Internet with Talk2M Why Talk2M ? 1. Technology review 2. Very often, the requirements for the ideal solution are not or difficult to meet Or we want to access eWON connected to the Internet through the local LAN In most of the case, the firewall blocks all incoming traffic In conclusion, only outgoing traffic is allowed (e.g. browsing HTTP or HTTPS website) Customer LAN Internet IP source IP dest > Remote Connectivity Solutions Internet with Talk2M Talk2M resolve these common connection problems in 3 steps Technology review 1. 2. 3. eWON is connected to Talk2M (VPN link) User is connected to Talk2M (VPN link) Talk2M interconnects the 2 VPN links All devices with Ethernet & TCP/IP or serial protocol behind eWON can then be reached Internet IP source VPN link VPN link VPN Tunnel User Customer LAN IP Dest > Remote Connectivity Solutions Duplex, Remote Access eSync Connect, Simplex, From RTU * Connection direction Which remote access solution/tool ?
