Figure 1-3. Remote Management of Multiple Shelves at Two Sites Using Multishelf TAO

The Multishelf TAO firmware allows the DSL circuits in a single shelf or a network of shelves to be managed from a single point-of-access (the EMU-830 console port of one shelf or using a Telnet session to one EMU-830). The alarm status for each shelf in a multishelf network can be viewed on a single Network screen (Figure 1-4 on page 1- 5), and the alarm status of each DSL circuit in a selected shelf can be viewed on a single Main Menu screen (Figure 1-5 on page 1-5). Each EMU-830 constantly monitors the DSL cards in its shelf for alarm conditions and automatically updates the alarm status.

From the TAO Network screen (Figure 1-4 on page 1-5), you can access any shelf in the network and then, from the Main Menu screen (Figure 1-5 on page 1-5), log into any DSL card installed in the shelf. Logging into an DSL card provides access to that card’s maintenance menus and is equivalent to connecting a terminal directly to the Craft port on the HDSL card.

Note: HDSL cards cannot be directly managed from their front-panel craft port when the EMU-830 is installed in the shelf. G.SHDSL (UTU-91x and WD92xGx) cards can be managed from their front-panel craft port when the EMU-830 is installed in the shelf. Telnet can also be used to manage multiple EMU-830s using multishelf TAO in the same logical IP network.
