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.

5INSTALLATION
This chapter describes the basic steps that are required to set up a system using the AM4. It is recommended
that if two desktop units are to be connected they should be tested back to back to check for correct
operation before deployment.
5.1 LED POWER ON SEQUENCE
During the power up/self test sequence the WAN LNK and ACT LEDs are both on continuously and the ALM
led flashes for around 14 seconds. The WAN LNK and ACT LEDs will then go out and the four LAN LEDs will
flash once.

After restarting your PC, open the Inernet Explorer or Netscape Browser to connect to the AM4. Type in the
default IP address for the AM4 into the Address/URL Line of the browser and press the Return key., e.g.
http://192.168.0.1
The default IP address and sub net-mask of the AM4 is 192.168.0.1 and 255.255.255.0. Because the AM4
acts as a DHCP server in your network, the AM4 will automatically assign an IP address for your PC in the
network.
Note:- If you have two or more AM4 units connected to the same network then you must change the IP
address of the AM4.
You will now be prompted to type in the default User Name and Password and click on the OK button.
The default User Name is root.
The default password is root.
For security reasons we suggest you change both the user name and password. Ref to section 6.7
