6.8.10 Central Tie Line Bad
Figure 36 Central Tie Line Bad
Since the loop is not complete, the Standby EXB turns on its network switch to
pass traffic over the Standby WAN line.
In this condition, the program can talk to the units as follows:
EXB
Forward
(Clockwise)
Reverse
(Counter-Clockwise)
Main (Central)
Yes
No
Remote Main
Yes
No
Remote Standby
Yes
No
Standby (Central)
Yes
No
Based upon this, the program determines that the Central Tie Line to the Standby
EXB unit is bad.
Note that if the MCNRCD PCs at the central site are connected to the Standby
EXB, they may actually be receiving data via the Standby path.
Other possible causes for this display could be:
1. Bad MCN Network port on the Standby EXB unit.
