UNIT INSTALLATION USING THE AUTO-CONFIG FEATURE
Introduction
AUTO-CONFIG allows the service provider to gain initial access to a newly installed IAD while in its factory
default state. This eliminates the need for a skilled technician on-site during installation, as it only requires
someone to make the network interface and power connections to the IAD. After accessing the unit, the
service provider remotely loads a configuration script. A fail-safe timer is then set and the configuration is
saved. Next, the service provider reprovisions the network to match the IAD's configuration and accesses
the unit. If the service provider can access the unit, the
AUTO-CONFIG was successful, the unit is
operational, and the fail-safe timer should be cancelled. If access is not gained prior to the fail-safe timer
expiration, the fail-safe mechanism is invoked and the IAD returns to the default configuration.
This DLP details the steps involved in an IAD installation using the
AUTO-CONFIG feature.
Prerequisite Procedures
The unit must be at factory default. If the unit is not a new unit, factory default the unit by one of the
following methods:
• Select
SYSTEM UTILITY>TERMINAL MODE. At the > prompt, type fac. You will then see “Restore Factory
Defaults and Reset Unit? (press 'y').” Press the y key to confirm default. The unit then resets.
• If connected to the
CRAFT port, power reset the unit and then restore power to the unit while holding
down the F key. You will then be prompted to confirm the factory default.
Obtain 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-009, Saving the Current Configuration Using TFTP.
• A script obtained via the terminal mode. See DLP-013 (Saving the Router's Configuration section only).
The service provider's access network Layer 1 must be provisioned to map a single 64K
DS0 from the provider's network to DS0 24 on the customer's T1 circuit with matching
circuit parameters (ESF, B8ZS).
