The ZCOM Subsystem is initialized by the zmon daemon which reads a memory image file and downloads appropriate firmware to the ACC Mux interface cards. The memory image file is created by running the ttgen utility on an ASCII configuration file which contains information such as what protocol will be used on the various ports of the ACC Mux cards, and protocol specific configuration.
