5. Once the L2 protocol detection is complete, the service provider can telnet into the unit using the IP
address assigned by the router/DHCP server.
6. Load the desired configuration file. The config file may be one of the following two formats:
• A .cfg file which is loaded via TFTP. See DLP-9, Saving the Current Configuration Using TFTP .
• A script obtained via the terminal mode. See DLP-13 ( Saving the Router's Configuration section
only).

and typing fstimer start x , (where
x is in seconds) at the > prompt. Select a value for x which will allow enough time for the service
provider to reconfigure the network to match the unit's new configuration and which will allow an extra
3 to 5 minutes for the unit to sync up with the network.
8. Type Save at the > prompt. This applies all configuration changes and the current connection is lost.
9. At this point, the service provider reconfigures the network to match the unit's new configuration.
10. After the network configuration is complete, the service provider attempts to connect to the unit. If the
connection is successful, deactivate the failsafe timer by selecting S

The service provider's access network Layer 1 must be provisioned to map a single 64 K
DS0 from the provider's network to DS0 24 on the customer's T1 circuit with matching
circuit parameters (ESF, B8ZS).
Set the failsafe timer prior to doing the save. Typing save will apply the configuration
changes, and the unit will not be accessible until the network is reconfigured.
