programs on their respective channels.  Specific channels are also set up for the
transmission of Internet content.  

Synchronizing 
Finding a 
channel in the 
broadband 
network 

After being switched on, the cable modem searches the entire frequency band for a
channel used by the provider to send information from the Internet.  Because the
bandwidth is so great, the first time the log-on procedure might take a while.  As soon
as the corresponding channel is found, the Sync LED on the 

ELSA MicroLink Cable

flashes.  The next time the cable modem is switched on, it will first look for the channel
it found the previous time, and thus find the wanted information at a substantially faster
rate.  However, if the cable modem is used on another connection, it may have to search
the entire frequency band again.  

To speed up the search, providers can preset the

 to search the

particular frequency bands that they normally use.  

Do not change these settings yourself without consulting your provider.  

Registration 
Exchange of 
administration 
information 
between head-
end and cable 
modem 

When a channel for communication with the provider has been found, the headend gives
a set of instructions to the cable modem that is important to the operation in the cable
network.  This process is called registration.  It includes: 

K

The confirmation of the found channel or the transfer to another channel 

K

The allocation of an IP address that is valid in the cable network, along with a
suitable netmask 

K

Information on the provider’s server addresses 

K

The current time

After the registration is completed successfully, the Reg’d LED on the

Cable

 lights up and the cable modem is ready to access the Internet.
