<p>PURPOSE:To facilitate the operation from a remote location by displaying a call control section to an existing terminal adaptor and providing an ATM cell multiplexer section, an ATM cell multiple address communication distributing section, an address filter section and call control information use ATM cell composition decomposition section to the adaptor in relation to the arrangement. CONSTITUTION:Existing terminal termination sections 231-23n of existing terminal adaptors 201-20n implement termination processing and its output information is converted into an ATM cell by a cell composition section of user information ATM cell composition decomposition sections 221-22n and the cell is outputted to nextstage ATM cell multiplexer sections 251-25n. On the other hand, call processing information from each existing terminal equipment or a manmachine interface is processed by call control sections 271-27n and converted into a call control information ATM cell with the call control information ATM cell composition decomposition sections 241-24n outputted to next stage multiplexer sections 251-25n to output the user information and call control ATM cell to specific interface signal termination sections 211-21n. The termination sections 211-21n converts the cell into specific interface signals a1-an, they are sent to a broad band line adaptor 10, the signal is converted into an ATM cell and outputted to a termination section 11.</p> |
