RTAU OPERATION

Summary: This procedure provides instructions for operating the Remote Test Access Unit (RTAU). The RTAU can be used to drop or insert DS1 signals either toward the network (DS3 interface) or the customer interface (i.e., the DS1 distribution modules) for monitoring or intrusive testing.

Note: A “toggle” field type means you can press the space bar to view and select the next option that is described; or press the “R” key to view and select the previous option. An “input” field type means you must type an entry in the field according to the parameters described. A “fixed” field is locked, and cannot be changed by the user.

Note: Edits can be made in the configuration database in one of two ways: 1) If the complete field is highlighted, use the space bar to toggle forward or the “R” key to reverse toggle through the options for that field. 2) If only the first space or the field is highlighted, type in the data that applies to that field.

Note: Edits can be saved into the configuration database after each change is made in

one of two ways: 1) Press an arrow key and then Enter or Return once; or 2) Press Enter or Return twice after all selections and entries are made in the screen but before leaving the screen. If the entries have been accepted, a message “Configuration Successful… Press Any Key To Continue” appears on the screen.

Note: Press CONTROL-A for help information on moving around and editing fields.

Note: Be sure to configure the line card to be tested before setting up test access.

Note: The RTAU’s status can also be displayed using the Shelf Status screen, where the letter “R” in the TAU slot column means an RTAU is present.
