Hi, Brian
What about if I use same ip address on the serial and bri interfaces ?
Here is more detail information.
Actually, this is the isdn configurations in our production network.
We have a PRI on the central site and BRI connections on the client sites.
For each connection, the serial and isdn interfaces have the same ip
address.
I already tested and made sure that the isdn circuits worked fine.
But, periodically the clients complained about their lost connectivities and
I found that
the backup ISDNs didn't work, which turned out telco circuit problems.
So, my question is to test the ISDN regularely to make sure the lines are up
while keeping the serial lines up.
thanks,

Take the standby command out of the serial and then it's just a normal
ISDN line. You can place a call by sending packets that match the dialer
list or you could use the isdn call command to trigger a manual call.
Rack4R4#isdn call interface bri 0/0 ?

Groups,
Currently I am using ISDN to back up a primay link failure with " backup
interface bri0" command under serial interface.
#sh int bri0
bri0 is standby mode, line protocol is down
I am looking for a way to test isdn line to see if it works without
bringing
down the serial line.
Any help !!!
Wol
