Tahoe 4681 (4-port G.shdsl.bis/FastEthernet modem card)
dsl
This command is used to configure specific DSL line. Following options are available:
dsl < line > speed < value >
– sets the throughput of a single line. The speed ranges from
from 64 to 5696 kbps. New speed is set after renegotiating the DSL connection.
dsl

line
>
type { master | slave }
– selects modem type. New type is set after
renegotiating the DSL connection. One modem is always set as a master, while the other one
as a slave

mod { auto | tcpam32 | tcpam16 | tcpam8 | tcpam4 | pam16 |
pam8 | pam4 | pam2 }
– selects line coding (modulation). The TCPAM32 modulation is
recommended, as it is the most efficient – the rest is available to provide compatibility with
devices from other manufacturers. The TCPAM32 allows throughputs from 256 kbps to
5696 kbps per line, while TCPAM16 – from 128 kbps to 2304 kbps and TCPAM4 – 64 kbps.
The
auto setting forces use of TCPAM32 for speeds greater than or equal to 256 kbps per line
and TCPAM16 or TCPAM4 for lower rates.
dsl < line > txgain < value >
– sets transmitter gain. The gain can range from 0.0 to
1.6. The modem reach may be slightly higher if the gain is increased. New mode is set after
renegotiating the DSL connection.
dsl < line > reset
– renegotiates connection
dsl show
– shows current settings
eepromdump
This command displays the complete contents of the EEPROM (non-volatile) memory in hexa-
decimal form. It is used for debugging only.
eraseconfig
The eraseconfig command erases whole configuration from the EEPROM. After rebooting the
modem it will return to its factory defaults. Until the reboot it will continue to run with its cur-
rent settings, which can be saved again using write command.
exit
This command closes the configuration session and disconnects user from the modem.
