  • Page 11: Chapter 1. Introduction

    T3 D/I module has two T3 interfaces. The T3 D/I module may terminate between 2 and 28 T1s as the T3 into the ATLAS and pass through the remaining bandwidth out of the secondary T3 port. The secondary T3 port may not be used to terminate bandwidth on the ATLAS, but passes the T1s back out the primary T3 interface.

  • Page 12: Functional Description

    Figure 1-1. T1 Bandwidth Management Application FUNCTIONAL DESCRIPTION The T3 Module can be installed in any available option slot in the ATLAS chassis. The status of the module itself, as well as the circuits to which it interfaces, can be viewed from the ATLAS front panel.

  • Page 15: Chapter 2. Installation

    Remove the option slot cover plate from the ATLAS 800 rear panel. Slide the T3 Module into the option slot until the module is firmly positioned against the front of the chassis. Fasten the thumbscrews at both edges of the T3 Module.

  • Page 16: Wiring

    The T3 Module automatically executes a self-test when it powers up. Any previ- ously configured setting for the T3 Module is automatically restored upon power up. If the T3 Module fails one or more of the self-tests executed during power up, an error message is displayed on the LCD.

  • Page 17: Chapter 3. Operation

    The ATLAS System Controller automatically detects the presence of the T3 Mod- ule when it is installed in the system. You can configure and control the T3 Mod- ule from several sources. Table 3-1 shows the various sources, their purpose, and their access.

  • Page 18: Menu Access
