Table 4- 2 Assignment of byte 1:
Bits 6 + 7 Bits 4 + 5 Bits 2 + 3 Bits 0 + 1
Configured interface Path status
Coding for substitute path Coding for main path Substitute path (2nd
path)
Main path (1st path)
● 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)
Status of bit 5
(7)
Status of bit 4
(6)
Meaning
0 0 Coding for Ethernet interface X1 (decimal: No. 0)
0 1 Coding for Ethernet interface X2 (decimal: no. 1)
1 0 Coding for Ethernet interface X3 (decimal: no. 2)
1 1 Coding for serial interface X4 (decimal: no. 3)
● Path status
–
Main path = 1. Path (bits 0 + 1)
– Substitute path = 2nd path (bits 2 + 3)
Status of bit
1 (3)
Status of bit
0 (2)
Meaning bit 1 Meaning bit 0
0 0 Bit 1: Path not current Bit 0: Subscriber not reachable
0 1 Bit 1: Path not current Bit 0: Subscriber reachable
1 0 Bit 1: Path current Bit 0: Subscriber not reachable
1 1 Bit 1: Path current Bit 0: Subscriber reachable
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).
