DSL communication apparatus, and download method of DSL communication program

摘要

A host manages a ROM that stores a handshake program for executing a handshake sequence and an initialization program for executing an initialization sequence. During the handshake sequence, the handshake program is retrieved from the ROM to download the program to a non-resident memory of a program area. Upon completing the handshake sequence, the initialization program is retrieved from the ROM, to download the program to the non-resident memory, replacing the handshake program.
