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 interconnected to form a Local Area Network
(LAN). This method of management is referred to as Multishelf Terminal Access Option (Multishelf TAO).
• One or more shelves of HDSL or G.SHDSL circuits can be managed over a LAN using the Simple Network
Management Protocol (SNMP). SNMP can access a shelf through its 10BASE-T Ethernet port or through its
Serial Line Interface Port (SLIP) over dial-up modem connections. These methods of management are referred
to as SNMP through LAN and SNMP through SLIP. The StarGazer application can be used to manage
WorldDSL shelves with the EMU-830 using SNMP through LAN.
• Management of a single shelf or multshelf TAO using Telnet.
The EMU-830 List 4A and List 6A are CE marked.
