WAN
Wide Area Network
Data network with a large geographical span, such as the Internet. telephone or enterprise
networks. The following WANs can be used with SINAUT:
● WAN, classic
SINAUT communication is possible via the following networks:
– Private or leased dedicated lines
– Analog telephone network
– Digital ISDN network
– Private wireless networks (directional or omnidirectional wireless and private mobile
– Mobile wireless network
A classic WAN is connected via suitable transmission device (modem) to a serial
interface of the TIM.
● WAN, IP-based
SINAUT communication is possible via the following IP-based networks:
– Over wireless by using special wireless systems optimized for Ethernet, for example,
– Via fiber-optic cable, for example in conjunction with SCALANCE X switches with
– Over public networks and Internet with DSL or GPRS
– Over wideband systems such as OTN, PCM30 etc.
An IP-based WAN is normally connected to an RJ-45 interface of an Ethernet TIM via an
Ethernet-compliant module.
In SINAUT ST7, the serial interface of a station TIM 3V-IE can be connected to a GSM
network via the GSM modem MD720-3 to allow use of GPRS. After the necessary
activation of the MSC protocol in STEP 7, the serial WAN interface behaves like an
Ethernet interface.
