Introduction - Tahoe 684 User Manual

1 1.
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.
Tahoe
transmission with speeds up to 19456 kbps on 8-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 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
unwanted traffic basing on IP addresses, TCP or UDP ports and protocols
appearing in the received packets.
The system firmware is stored in the Flash memory - it is possible
to update it using the TFTP protocol. The configuration is stored in the
EEPROM memory.
