6.8.8 Standby WAN Line Bad
Figure 34 Standby WAN 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)
No
Yes
Based upon this, the program determines that the Standby WAN Line is bad.
Other possible causes for this display could be:
1. A bad cable from one of the Standby EXBs to the Standby WAN line.
2. Bad Standby or Standby Remote EXB Module.
Possibly a bad modem in an Analog / Telco EXB unit
Possibly a bad serial port on a Serial EXB unit.
