<p>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.</p> |
