Is someone who can help me? What is the meaning of the result "%Network not in table"?

The Serial interface is not up/up, it sees a physical connection but no protocol.
The connected 192.168.1.1 address will only be in the routing table if interface and line protocol are both up.. This is a PPP encapsulated interface and it appears possible the other end of the PPP link isn't uup or configured properly.

Now I understand. Thanks for the answer. :)
May I know what are the other factor of going down of the line protocol (Line protocol is down)? Can you give me an other scenarios or examples?
Thanks in advance..

There are many scenarios. I use a mostly HDLC encapsulated serial interfaces on leased T-1 circuits, a reason line protocol could be down might include the telco provider having some of its switch gear down or not working right.
Here's the Cisco direction for PPP interfaces.
