Figure 1-2. Local Management of a Single Shelf Using RS-232/Telnet
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.
