That's depending on the WAN side what technology you are using. If you are using Frame Relay or HDLC between the WAN side via serial link, there will be no collision. Since Frame Relay and HDLC are connection-oriented but not reliable. All the re-transmission are done by between 2 hosts of each opposite end. In case of using X.25, there will be a collision since X.25 is connection-oriented and reliable. 2 routers between the serial line will do all the re-transmission. So there will be a collision.
