LAN communicating apparatus and interface between the same and LAN terminal

摘要

In a LAN communication apparatus hooking up a telephone and a LAN terminal, a downstream LAN interface for hooking up a LAN terminal is provided in addition to a telephone interface for hooking up the telephone. Further, a voice-packet from the telephone is transmitted advantageously over a data-packet supplied from the LAN terminal to an upstream LAN. This structure allows the voice data to be transmitted to the upstream LAN advantageously over other data although the LAN terminal hooked up to the downstream LAN sends out volume of data. As a result, the voice data can be transmitted to the upstream LAN without delay.
