3Com Dual 56K manual Bandwidth Management, Remote Management, Protocols, ITU-T ITU-T V.42bis MNP

Features 19

■Network Address Translation (NAT) between LAN and WAN, which allows multiple users on the LAN to share a single remote connection and user account.

■Intelligent NAT, an enhancement to NAT which enables UDP applications to work with the Dual 56K LAN Modem.

■Multiplexing traffic from several computers to remote destinations

Bandwidth Management

■Automatic call initiation (also known as dial-on-demand routing)

■Automatic disconnection of idle calls after a specified length of time

■Multilink PPP, which combines two PPP calls on two analog lines into a single, high-speed network connection.

■Bandwidth on Demand using Bandwidth Allocation Control Protocol (BACP)/Bandwidth Allocation Protocol (BAP), based on a specified threshold.

■Dynamic Bandwidth Allocation (DBA), which allows you to place a voice or data call while a Multilink PPP call is active.

■Manual call connection and disconnection

Remote Management

■Remote management via Web browser-based interface

■Remote firmware upgrades
