*Mar 1 03:37:47.923: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Virtual-Access1, changed state to up
*Mar 1 03:35:57.217: %ISDN-6-CONNECT: Interface BRI0:1 is now
connected to 5552053 HQ
Step 2 Wait for the “ISDN-6-CONNECT” message.
Step 3 Enter the ping command, followed by the IP address of the central-site router, a
second time:
Router# ping 192.168.37.40
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.37.40, timeout is 2 seconds:

Step 4 If the success rate is 100 percent, this verification step is successful.
Step 5 If the success rate is less than 60 percent, take the following steps:
a. Use the show frame-relay pvc command to confirm that the DLCI for the
Frame Relay interface is active.
b. Use the show interface serial0 command to confirm that the “Serial0 is up,
line protocol is up” message is displayed in the command output.
Step 6 To continue configuration, reenter global configuration mode.

Follow these steps to configure how and when the ISDN line connects to the
central-site router.
