Usage Guidelines
The router resets the hardware each time the serial restart timer expires. This command is often used
with the dial backup feature and with the pulse-time command, which sets the amount of time to
wait before redialing when a DTR dialed device fails to connect.
When the count value is set to 0, the hardware is not reset when it goes down. In this way, if the
interface is used to answer a call, it does not cause DTR to drop, which might cause communications
device to disconnect.
Example
On Cisco MC3810 interface Serial 0, this example shows the restart delay set to 1 second:
