Problem is you do not have the telnet service enabled 
and a proper port number selected. My guess would be that 
the telnet port address is set to zero which disables telnet. 
By the way, this router has SSH available on it, 
If you need to remote admin this router from the WAN side, 
you should use SSH as this router/modem is capable of doing so.
You are at this point, just trying to admin the router using
a computer (GNU/Linux) which is connected to a LAN side interface
port on the router, ...right? 

Note that this router has two major command modes,
SHELL and CONFIG.(pg. 105) You can determine which mode 
you are in via the prompt. On (page 118) it shows how to
switch between the two CLI modes. (page 146) shows you how
to enable LAN management. In CLI Config mode you would type:

set management lanmgmt enable on 

At the bottom of (page 148) note the listed commands 
for the configuration of telnet. 
The manual mentions that by default the port is set to 0
which disables telnet. So from the CLI config
mode prompt you would type:

set management remote-access telnet-port 2323

2323 as an example. Then from a terminal on a computer connected 
to a LAN side port of the router you would type something like
this in CLI SHELL mode:

telnet 192.168.1.64 2323

Double check your Home Network page in GUI for proper gateway ip
address for the above. I have never had access to this model
router/modem, so I do not know if /all/ the settings are available
from the web interface GUI. You may only be able to manage certain
settings from the CLI.
