Total Access 600 Series System Manual Section 5 DLP-18

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.

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).

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).

7.Set the failsafe timer by selecting SYSTEM UTILITY > TERMINAL MODE 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.

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.

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 SYSTEM UTILITY > TERMINAL MODE and typing fstimer stop at the > prompt.

11.If the connection is not successful, wait until the timer expires and the unit will factory default back to the AUTO-CONFIGmode. Repeat steps 4-10 of this DLP.
