I have to connect serial to serial between 2 Cisco router: Cisco 1600 series & Cisco 1005 respectively, with all IP configured. But they can't seems to connected, nor ping to one another.
I know something must be configure when Serial to Serial connection is used.
Anyone can advise me on that?
Thanks.

What's your (wide area network) protocol encapsulation? i.e. Are you using HDLC, SDLC, ATM, Frame?
Can you see the routers' CDP neighbors? Are you serial up/up? When you try to ping, do you get "unreachables?" Or "no response?"

I will assume that the routers are connected back to back with no modem or CSU via one DTE and one DCE cable ?
If this is the case then you have to configure the DCE interface to provide the clock. This is an interface configuration command:
config term
interface Serial0
clock rate ?
where ? is one of the following clockrates :
1200
2400
4800
9600
19200
38400
56000
64000
72000
125000
148000
250000
500000
800000
1000000
1300000
2000000
4000000
Note that RS232 will only run up to 500k I think and that V.35 can run faster - I am unsure of the limits but there is a physical limit of the electronics in the serial interface for either type of serial applique.
I hope that's what you were looking for ?
