Configured interface
The TIM interfaces "Ethernet 1" (IE1), "Ethernet 2" (IE2), "Ethernet 3" (IE3) and WAN1
are numbered through from 0 . 3 (decimal):
–
0 = Ethernet interface IE1 (X1)
–
1 = Ethernet interface IE2 (X2)
–
2 = Ethernet interface IE3 (X3)
–
3 = Serial interface WAN1 (X4)

Coding options of byte 1
Same coding of the configured interface for the main and the substitute path means that
there is no path redundancy (only one interface configured). The path status is output via the
bits of the main path (1st path).
