2INTRODUCTION
The AM4 SHDSL (Single-Paired High Speed Digital Subscriber Loop) modem complies with the G.991.2
standard with 10/100 Base-T auto-negotiation. It provides business-class, multi-range from 64kbps to
2.304Mbps. The AM4 is designed not only to optimize the service bit rate from central office to customer
premises, it also integrates high-end Bridging/Routing capabilities with advanced Multi-DMZ, virtual server
mapping and VPN pass-through functions.
Because of the rapid growth of networks, virtual LAN has become one of the major new areas in the
internetworking industry. The AM4 supports port-based and IEEE 802.1q VLAN over ATM network.
The AM4 provides not only advanced functions, Multi-DMZ, virtual server mapping and VPN pass-through but
advanced firewall, SPI, NAT, DoS protection serving as a powerful firewall to protect the secure connection
from outside intruders. (Note: Firewall available only on AM4F variant - see Ordering Information for details.)
The AM4 supports four port 10Base-T /100Base-T auto-negotiation and auto-MDIX switching ports to meet
the enterprise needs of modern networks.
The AM4 allows customers to leverage the latest in broadband technologies to meet their growing data
communication needs. Through the power of SHDSL products, you can access superior manageability and
reliability.
