Changing Configuration Options

The E1 DSU/CSU is an intelligent device that displays only valid options for the current configuration. Therefore, you are only presented with menu choices that are consistent with the current configuration and operational state of the E1 DSU/CSU; invalid combinations of configuration options do not appear. For example, menus displayed for the Model 3172 (2 ports) and the Model 3174 (4 ports) differ due to the number of ports available. Also, if the DTE Drop/Insert interface selection is disabled, many of the menu choices do not appear. Be aware that although all options are shown in this guide, what you see on your E1 DSU/CSU varies with your configuration.

The E1 DSU/CSU offers four sets of configuration options located in the following memory areas:

Active (Activ). The configuration option set active for the E1 DSU/CSU is stored here. Before a configuration option set becomes active for the E1 DSU/CSU, you must save the set to the Active area. When the E1 DSU/CSU is shipped from the factory, the Active configuration option set is identical to the Factory set. This area can be written to and controls the current operation of the device.

Customer 1 (Cust1). The first of two sets of customer-defined configuration options. This area can be written to.

Customer 2 (Cust2). The second of two sets of customer-defined configuration options. This area can be written to.

Factory (Fact). This is a set of configuration options preset at the company. This set is determined by what is considered to be the most common configuration used in the E1 DSU/CSU market. Factory options are read-only.
