FAQs

Q.  Can I have more than one computer attached to a Terayon modem?

A. Yes, Terayon cable modems do provide this capability, but you will need to 

install a hub into your system and you must arrange for this service with your 
cable service provider. Some service providers limit the number of computers 
connected to the modem.

Q. Can I connect the Terayon cable modem to a hub or switch?

A. Yes, you can connect the Terayon cable modem to a hub or switch. There are 

two ways to successfully complete a physical connection.

1. Buy a cross-over cable and connect the port labeled 10Base-T on the Ter-

ayon cable modem to one of the ports on the hub or switch.

2. Many newer hubs and switches have an “uplink” port specifically designed 

for cascading. Connect this uplink port to your Terayon cable modem and it 
should work without a cross-over cable. Connect your PC to another avail-
able port.

NOTE:

While you may be able to successfully complete a phys-
ical connection to a hub or switch indicated by a green 
PC LED, you cannot obtain additional IP addresses 
unless your subscription allows for more than one IP 
address. Contact your cable operator for more infor-
mation.
