ISDN Connection

Test

[Enter 4] This command instructs the router to perform a loopback test of the

ISDN line. A call is placed from one B channel to the other, and data is

passed. A failure of this test indicates a problem either with the ISDN

line itself or with your current ISDN conﬁguration. Note the error

message that you receive and see your network administrator.

Manual Call [Enter 5] This command allows the user to place a manual call to a remote node

and tests the connectivity to that remote node. As the call is placed,

traces are displayed on the screen showing the progress of the call

setup and protocol negotiation.
