ABSTRACT:
A Set-Top Box configured with a modem and a Main Circuit Board determines an IP address of the modem by periodically broadcasting a Discovery Packet from the modem to a broadcast address, the Discovery Packet comprising at least the IP address of the modem. At the Main Circuit Board, the broadcast Discovery Packet is received from the modem and the IP address of the modem is ascertained from the broadcast Discovery Packet.
