Page 5: Introduction
Introduction Thank you for purchasing the Tahoe 684 modem. We did our best to ensure highest reliability and performance of our products. Devoting many years of research and development we are proud to provide a superior quality device unfolding new possibilities for the use of the copper lines. -
Page 6: Interfaces
It is a 8-pin RJ-45 connector used to connect the leased line. The pinout is similar to an EIA-568 (Cat5) connector. Subsequent lines may be interchanged between modems - that condition will be automatically detected. The polarization of a line is not important.

After connecting a LED named “LAN Link” should be lit. ® In the Tahoe 684 modem the FastEthernet interface has following status LEDs: LAN Link - lit, when modem is connected to a LAN LAN Act...

Page 8: Modem Configuration Using Built-In Keyboard And Lcd
The easiest way to configure a modem is to use the four-button keyboard and the LCD. After switching the power on, an information about the modem type, the line throughput and state will be displayed: Tahoe 684 35`C 19456 kb/s... -
Page 9: Line Coding
After pressing Enter the throughput may be set using up/down buttons. It may be chosen from 256-19456 kbps range with 256 kbps step. The actual throughput of each line is 1/4 of the throughput displayed. Different rates for each line may be set using the serial console or the telnet connection (see chapter 4). - Page 10 The “Auto” setting forces use of 32-TCPAM for speeds higher than or equal to 256 kbps per line and 16-TCPAM for lower rates. 3.4. Write configuration to EEPROM Write config to EEPROM Every change to the configuration will be lost after reboot or power off unless the settings are written to the EEPROM.

Connection reset Connection reset (press Enter) After pressing Enter the G.shdsl link will be disconnected and negotiated again. 3.8. - Page 12 throughput and link state). While having this screen displayed, you may press Enter to display line attenuation in dB (proper value appears only after the line synchronizes): ATT: (dB) Pressing Enter again will show so-called Noise Margin (or Signal- Noise Ratio). This is the difference between the useful signal and the background noise.

IP address is possible from anywhere in the network. After connecting a password prompt will appear: User Access Verification Password: The default password is “Tahoe” (case sensitive). If the password entered is correct, a command prompt will appear: Tahoe> 4.2. Serial console If the telnet connection is not possible (e.g. -

(the IP address to be deleted should be typed instead of “10.0.0.2” ). A static ARP entry may be added using “arp add”: Tahoe> arp add 10.0.0.3 00:50:13:E9:5C:01 The dynamic hardware address resolution may be disabled using the “ifconfig” command. If it is disabled, only those stations may connect to the modem, whose IP and MAC addresses are entered into the ARP table using the “arp add”... - Page 15 transparent - completely transparent bridge, inaccessible under its IP address - this mode may be disabled only through the serial console or the LCD and keyboard. Entering “bridge list” displays a list of MAC addresses with the name of the interface on which certain address was heard. Note: To make bridging work properly interfaces used in the process have to be indicated.

Here is an example: Tahoe> dhcp DHCP/BOOTP server default-lease-time 43200 max-lease-time 86400 network "lan" (eth0): default-lease-time 43200 max-lease-time 86400 domain-name tahoe.pl...
- Page 17 4.3.7.2 4.3.7.2. Basic DHCP server configuration rules Before starting using DHCP server please read following guidelines: the configuration is organized in a hierarchical manner - the most general group of settings is “network” - the physical network connected to the modem. Any number of IP “subnets” may exist within a network.

- Page 21 Separate values selected from 64-4864 kbps range may also be set for each of the lines. That possibility is useful if the lines differ in their quality. New throughput will be set after entering “dsl reset” command. dsl type { master | slave } - sets the modem type - master or slave.

- Page 23 errors and other important data is displayed.. An IP address may be assigned to an interface, together with subnet mask and broadcast address. A dynamic ARP may also be enabled or disabled. The “bridge” parameter allows to include or exclude certain protocol from bridging, when the modem works in the bridge mode.
