Procedure
To reset the T1 access unit from the Control menu:
1. Follow this menu selection sequence:
Main Menu
→
Control
→
Reset Device
2. Select Yes. The T1 access unit reinitializes itself, performing a Device
Self-Test.
Restoring Access to the User Interface
Misconfiguring the T1 access unit could render the user interface inaccessible,
leaving it in a state where a session cannot be started via the COM port or a
Telnet session. If this occurs, T1 access unit connectivity can be restored via a
directly-connected terminal.
Two methods can be used to restore access to the user interface:
H
Reset COM Port – Allows you to reset the configuration options related to
COM port usage. This also causes a device reset, where the T1 access unit
performs a Device Self-Test. No security-related configuration options are
changed.
H
Reload Factory Defaults – Allows you to reload the Default Factory
Configuration, resetting all of the configuration and control settings. This
method is also useful when the user’s password(s) have been forgotten.
Selecting this method also causes a device reset. Reload destroys the
current configuration.
