1 Chapter OVERVIEW The EMU-830 provides management for HDSL and G.SHDSL circuits using either of the following methods: • 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 interco

Chapter 1: Overview September 25, 2006 In a remotely managed configuration, an external modem must be connected to the EMU-830 front panel V.24 (RS-232) console port. If enabled, alarm conditions cause ASCII messages to be transmitted autonomously over the dial-up network. These messages can be displayed on a monitor or sent directly to a printer. This provides the network operator immediate notification of problems. The operator can then initiate a remote TAO session with the local shelf to
