Installing the Cisco uBR924 Router
Verifying Installation
Step 3
Listen for the fax tone on the other end and verify that the fax is transmitted. When either end hangs up,
the call is torn down. The session ends, with each end going idle, waiting for another off-hook
condition.
Step 4
Verify that the fax was correctly received at the destination.
Backup POTS Connection
To verify the backup POTS line to the PSTN is operational:
Step 1
Simulate a power failure in the Cisco uBR924 router by disconnecting the 3-prong end of the power
cord from the power outlet—be certain to follow all safety instructions in the “Connecting Power”
section on page 3-10.
Step 2
Pick up one of the telephones connected to the VoIP ports and dial out over the backup POTS line. Wait
for a connection to be established.
Step 3
When a cutover call is in place, connect the 3-prong end of the power cord to the power outlet. Power
is immediately supplied to the router.
Step 4
Verify that the cutover call remains connected.
Step 5
Disconnect the call. The router automatically reboots.
Step 6
After the router has come back online, test one of the VoIP ports (see “VoIP Telephone Connection”
section on page 3-14) to verify that VoIP connectivity has been re-established.
