Not without it being added to the system. The easiest way I can explain it is MAC based VLAN assignment or DHCP reservations. The "computer" boots up and based on its MAC address it gets a specific configuration (different lan segment, dns servers etc). Each cable card has it's own ID number and associated with that ID number is a certain set of maps that get downloaded.
The funny thing is that two Tivo's in the same house/account can receive different configs. I helped someone that was getting 2-99 analog on one THD and 2-99 digital on the other. It was extremely
difficult to explain to the cable tech what was happening so I eventually said "can you just copy whatever is on unit 1 to unit 2?
