Title:
【発明の名称】PACS無線技術を特徴とする無線および有線アクセスのための統合電気通信システム・アーキテクチャ
Document Type and Number:
Japanese Patent JP2000504192
Kind Code:
A
Abstract:
Disclosed is a telecommunication system (52-82) that is both highly cost effective for small scale applications (for example, those having less than 80 lines), yet field upgrade-expandable via a backplane bus (68) to applications having a significant number of additional lines (for example, 30,000 lines). An integrated voice/data telecommunication system is utilized that is flexible enough to handle low bandwidth (for example 64 kbps mu-law) speech as well as high bandwidth multimedia data switching. The system may be configured as a low cost, standalone PACS system for "village telephony" or "PACS-on-POTS" applications, as an alternative to requirements for PACS infrastructure when appropriate wireless network facilities are unavailable.
