Classic WAN networks
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
wireless with time slots)
–
Mobile wireless network
A classic WAN is connected via suitable transmission device (modem) to a serial
interface of the TIM.
●
IP-based WAN networks
SINAUT communication is possible via the following IP-based networks:
–
Over wireless by using special wireless systems optimized for Ethernet, for example,
the components of a SCALANCE W IWLAN system
–
Via fiber-optic cable, for example in conjunction with SCALANCE X switches with
optical ports. This allows distances of up to 70 km to be covered.
–
Over public networks and Internet with DSL or GPRS
–
Private 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 (see section "Installation guidelines").
To allow use of GPRS, the serial interface of a station TIM 3V-IE can be connected to a
GSM network via the GSM modem MD720-3. This requires the MSC protocol to be
enabled in the STEP 7 > Properties dialog of the TIM > "Interfaces" tab. The WAN
interface then behaves like a virtual Ethernet interface.
