Introduction
Thank you for purchasing the Tahoe 681/682 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.

Tahoe 680 series modems are G.shdsl+ modems allowing data
transmission with speeds up to 4864 kbps on 2-wire line or up to 9728
kbps on 4-wire line. Thanks to powerful TCPAM-32 modulation
throughputs are much higher than using HDSL technique and reach is
nearly twice that of VDSL. Adding low cost of deployment, Tahoe
modems become an interesting alternative even for fiber optic
connections.
The modem exists in two versions:
®
¡
Tahoe 681 -
up to 4864 kbps on 2-wire line
®
¡
Tahoe 682 - up to 9728 kbps on 4-wire line, traffic is
automatically divided between two lines, fall back to 2-wire mode
is done automatically in case o line failure
The modem has a built-in TCP/IP router and an Ethernet
10/100Base-T interface allowing connection directly to a LAN. Router
software supports IP, ARP, TCP, UDP and ICMP protocols. It is
manageable using telnet, SNMP, serial console or built-in LCD and
keyboard. Traffic statistics are available through WWW. Modem status
messages can be sent to a central server using syslog protocol.
One network interface may support more than one IP subnetwork
thanks to interface aliases (eth0:0, eth0:1, etc.) and VLAN interfaces
(eth0.1, eth0.2, etc.). Modem may also work as a bridge - in this mode
both interconnected networks create one whole on the hardware level
®
(e.g. computers with Microsoft Windows™ operating system will see
each other in the network neighborhood).
A built-in DHCP/BOOTP server allows assigning of IP addresses,
network mask, router addresses and other parameters to the network
stations. DHCP/BOOTP Relay Agent listens for DHCP and BOOTP
requests and forwards them to a central server.
Modem supports Network Address Translation, i.e. makes it
possible for a whole network to access Internet using only one real IP
address. Additional firewall improves the network security by blocking
