84 modem is a G.shdsl+ modems allowing data 

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.
