2 different needs

Connection on purpose:1. Connection temporary oriented2. Simplex communication: machine/RTU -

>user3. Or… full duplex (bi-directional)

communication: user-machine/RTU-userOr persistent connection1. Duplex communication 2. And asset/site-to-site extranet

2 different technologies

Old style modem like: dial-up (Point-to-Point connections over telephone network) Embedded PSTN, ISDN or GSM data modemPurely IP though Internet network Embedded PSTN, ISDN, GPRS, EDGE, 3G,

ADSL modem or connection through LAN21

Internet connections: the ideal scenario

Requirements :1. Internet Service Provider (ISP) on the eWON side

should provide Public IP address and2. Firewall (ISP) should be transparent to the VPN

connection

Internet with Talk2MWhy Talk2M ?1. Very often, the requirements for the ideal solution are

not or difficult to meet2. 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)

Internet with Talk2MTalk2M resolve these common connection problems in 3 steps1. eWON is connected to Talk2M (VPN link)2. User is connected to Talk2M (VPN link)3. Talk2M interconnects the 2 VPN linksAll devices with Ethernet & TCP/IP or serial protocol behind eWON can then be reached
