    • One or more shelves of HDSL or G.SHDSL circuits can be managed by connecting a management terminal (or PC with terminal emulation software) to the EMU-830 of one shelf. The management terminal (or PC) can be connected to the EMU-830 either directly (or through modems over a dial-up network). When two or more shelves are present, the Ethernet ports of each shelf can be interconnected to form a Local Area Network (LAN).

    A total or partial failure of the EMU-830 affects only the centralized management capabilities of the system, it does not affect the DSL circuits deployed in the shelf. In case of EMU-830 failure, the HDSL cards can be managed directly from their front panel V.24 Craft port. To use the local management RS-232 interface of an HDSL card it is necessary to remove the EMU-830 from the shelf.

    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...

  • Page 15: Figure 1-4. Multishelf Tao Network Screen

    A multishelf network is created by connecting the local area network (LAN) to the 10BASE-T Ethernet connector available on a shelf. Each shelf must have an EMU-830 management unit installed. A VT100 terminal (or PC) is connected either locally or remotely (through modems), or through Telnet access to the console port of one EMU in the network.

  • Page 16: Snmp

    The operator can then initiate a remote TAO session with the local shelf to further diagnose and correct the problem. The EMU-830 and the DSL card firmware can be easily upgraded using the Upload utility from the TAO Main menu. This utility uses TFTP and Xmodem protocols.

    LOCK The EMU-830 List 6A includes a backup circuit for the 2.048 MHz external shelf clock. This circuit will continue to provide a 2.048 MHz clock to the DSL cards in the event the 2.048 MHz external shelf clock is lost. The software reports the status of this circuit and allows the user to set the severity of the alarm generated when the clock is lost.

  • Page 26: Multishelf Cable Connections

    Chapter 2: Installation ULTISHELF ABLE ONNECTIONS Note: Multishelf networks cannot be connected through a router because the local shelf uses UDP- broadcast messages as a mechanism to automatically discover other shelves in the network, and routers generally filter these broadcasts. A multishelf network is limited to 32 shelves. To connect the shelves using the 10BASE-T Ethernet connectors Step Plug an RJ-45 cable into the 10BASE-T connector at the rear of each shelf.

  • Page 27: Local Terminal Connections

    ONNECTIONS The console port of the EMU-830 in the local shelf can be connected directly to a VT100 terminal (or PC). Once connected, you can use the terminal (or PC) to access the EMU-830 console menus. The console menus allow you to configure each EMU and DSL circuit in a multishelf network, monitor and test system performance, and display the inventory of installed DSL units.
