DTE Port Maintenance

DTE Port Maintenance
The DTE port on the back of an IP Office Control Unit is not normally used when configuring an IP Office
system. However the DTE port can be used to erase the system's operational software and/or
configuration if necessary.
Instances where the system configuration may need to be cleared are:
• Forgotten IP Office system password: In this instance, erasing the system configuration from the
control unit allows you to access the control unit via a default configuration and then load the
backup copy of the old configuration (with all the system settings, user settings, etc.)
Due to the drastic nature of these actions, they should only be performed if absolutely necessary
to return a system back to working order.
Before using the DTE port to erase the system software and/or configuration, a backup copy of the
system configuration MUST be available.
Save a backup copy of the system configuration
Make a copy of the current configuration file by saving it offline before clearing the system software
and/or configuration. Having this backup configuration will save time and effort once the box is erased
and ready to have a configuration loaded.
PROCEDURE
To save an existing configuration file offline:
1. With the configuration file opened on Manager, click File | Save As.
2. On the Save As window, browse to the folder directory in which you want to save the
configuration file.
3. Click Save.
Configuring the DTE port settings
Access to the DTE port requires a serial cable wired as shown below using D-type plugs. The DTE port
on the IP Office Control Unit may be either 25-pin or 9-pin.
