Abstract: A data gateway unit includes a configuration information update unit for examining a connection state of a terminal on a customer premise network side, and for updating configuration information on the customer premise network; a service menu unit for enumerating, in response to the configuration information on the customer premise network which the configuration information update unit updates, available services the terminal on the customer premise network side can implement; and a service presentation and selection unit for notifying a user of the available services the service menu unit enumerates, and for accepting a service selected by the user. This can solve a problem of a conventional data gateway unit in that users unfamiliar with a personal computer, home bus, or system information, cannot change the setup of the system easily because of the difficulty to create the system information.

Abstract: A small and economical voice packet assembling/disassembling (PAD) apparatus, which includes only one packet assembler/disassembler for a plurality of channels. The packet assembler receives coded voice data from a plurality of CODECs provided for each channel, and assembles voice packets by using the coded voice data. The packet disassembler disassembles voice packets to coded voice data and supplies them to a plurality of CODECs provided for each channel.
