GARNET GAE-3020 Chapter 1. Overview 1.1 Introduction Garnet ADSL(Asymmetric Digital Subscriber Line) Modem GAE-3020 is an External stand-alone modem that provides users faster connectivity than conventional access technologies by offering up to 8 Mbps of downstream line rate and up to 640 Kbps of upstream over existing phone lines, which is asymmetric. It also provides interoperability and industry standards and protocols. Garnet ADSL Modem supports either G.992.1(G.dmt) or Splitterless G.992.2(G.
GARNET GAE-3020 monitoring program, which enables users to see speed of data streams, supports physical connect and disconnect and diagnose hardware malfunctioning. 1.3 Specifications Dimension : 135(L) x 188(W) x 35.5(H) Operating Temperature : 0~45 oC Operating Humidity : 10% to 90%, non-condensing Power Consumption: 4.05W Standards : ANSI T1.413 Issue 2 / ITU-T G.992.1, G.992.2 Frequency Range : 0.11~1.1MHz(Down) / 30KHz~110KHz(Up) Modulation : DMT (Discrete Multi Tone) Data Rates : Downstream : Max.
GARNET GAE-3020 Chapter 2. Installation 2.1 Before Installation Please be advised that if you do not yet subscribe phone service, it is impossible to get ADSL service. In this case, please contact your local service provider to have new telephone service. And please be informed that telephone service providers do not service all ADSL applications. Please contact your local Central Office on the applications and ADSL service providers may support different service protocols.

GARNET GAE-3020 2.3 Hard Ware Installation ☞ To install modem into PC, follow below steps. 1. Turn off your computer and all attached peripheral devices (printer, monitor, etc.) and unplug them from the electrical outlet. L CAUTION : To avoid risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged. 2. Attach power supply to power inlet connector 3. Plug power supply cable into standard electrical socket. 4.
GARNET GAE-3020 router. There is no installation of software on the PC for this, except for the normal Ethernet LAN adapter installation. The modem configuration can be viewed and modified through the console which is accessible through the RS-232 serial connection. To use the serial interface, a straight-through cable is needed between the modem and a terminal (could be a PC running a terminal emulation package).
GARNET GAE-3020 2.5 Set up Hyper Terminal • After the ADSL Modem is connected with PC by serial port cable follow below steps. • Start => programs => Accessories => Communication => Hyper Terminal Enter the Hypertrm.exe. • After the suitable name choose. Choose the suitable name and click OK.
GARNET GAE-3020 • Choose the Direct to Com1, Click ok. • Follow below setting, chick OK.
GARNET GAE-3020 2.6 Ethernet Bridge Configuration In the Ethernet bridge configuration, the modem bridges data between the local Ethernet LAN and the service provider. The ADSL link must be set up in RFC1483 mode with a PVC to communicate across. The PVC is assigned by the service provider. The bridge needs to be told about both the Ethernet interface and the 1483 interface. Since the modem is transparent, the PC’s default gateway must be set to the service provider’s IP address.
GARNET GAE-3020 2.7 Ethernet Router Configuration There are multiple ways that routing can be set up depending on the requirements from the service provider. The following routing methods are described below: • IPoA Routing • PPP Routing • Routing using NAT (can be used with either IPoA or PPP) 2.8 IPoA Routing When configured for IPoA, data is routed between Ethernet and Classical IP over ATM (RFC1577). The IPoA data runs over a PVC between the modem and the service provider.
GARNET GAE-3020 ip route add default 0.0.0.0 192.168.102.3 0:0:0:0 • The next command configures the IPoA protocol to run on PVC 700 with a peak cell rate of 50000 cells per second, using the port named “atm”: ip ipatm pvc add ipoa atm 700 pcr 50000 • Save the configuration and reboot the system. config save restart 2.9 PPP Routing When configured for PPP, data is routed between Ethernet and PPP over ATM. The PPP data runs over a PVC between the modem and the service provider.
GARNET GAE-3020 ppp 1 welogin fred password chap ppp 1 enable • Save the configuration and reboot the system. This is necessary when configuring the system from the console, because the following command can only operate on router interfaces which have already been created. config save restart • Enable forwarding between the router interfaces: ip relay all • Save the configuration and reboot the system: config save restart 2.10 NAT NAT can be used with IPoA routing or PPP routing.
GARNET GAE-3020 Enabling the DHCP Server To enable the DHCP server, a range of IP addresses need to be provided that the server can assign to clients. The example below shows the commands needed to supply the DHCP server with 99 IP addresses from 192.168.219.1 to 192.168.219.99 on the subnet 192.168.219.0 with the subnet mask of 255.255.255.0. The maximum lease time for each client is set to 86400 seconds, or 1 day. BOOTP clients may be serviced, and requests from unknown clients are allowed.
GARNET GAE-3020 restart Re-configuring the DHCP Server To re-configure the DHCP server, issue the disable procedure followed by the enable procedure. 2.12 VCI/VPI Value Configuration. Connect PC to Modem by RJ-45 cable and RS-232 cable, switching power on of the modem and set up Hyperterminal at Com 1(or Com 2) port for connection between Modem and PC. - At the Hyper terminal window, you can see prompt 0:20:2b:8d:40> help and you can find existing list of available commands.
