2.2 Configurations
The symbols used in the following configurations represent the various modules with their
LAN or WAN interfaces.
Note
Notes on TIM 4 / TIM 4R-IE
• The two WAN interfaces of a TIM 4R / TIM 4RD can both have the same function (for
example 2 x master) or different functions (for example node + master).
• With redundant WAN connections, a TIM 4 or TIM 4R-IE with two interfaces must always
be used because redundant paths always start and end on a TIM module.
