Disclosed is a method of transmitting data in a communication system. 0\xd71017 atomscm3 and with a diameter of a COP occurring region not more than a diameter of a crystal, slicing a wafer from the silicon ingot after doping the silicon ingot with phosphorus, forming a polysilicon layer or a strained layer on one main surface of the wafer, and mirror polishing the other main surface of the wafer. The communications apparatus then converts the received IPv4 multicast packet into an IPv6 multicast packet and transmits the converted IPv6 multicast packet to an IPv6 network where it is required to be sent. The path of the pen tip is determined by decoding the associated maze pattern and by matching the captured images with document images. Root cause analysis may be performed in accordance with the manifest tree.
