Beyond Videophones: TeamWorkStation-2 for Narrowband ISDN
: TeamWorkStation-2 (TWS-2) is introduced to connect two sites with a desktop overlay service using narrowband ISDN (N-ISDN) and the CCITT H.261 standard. Based on the experience gained with TWS-1 use within NTT, we radically simplified the system architecture of TWS-2. Experimental sessions confirmed that TWS-2 is useful for freehand drawing and gesture-intensive design sessions even with the basic rate interface (2B+D). Video delay and jerkiness did not prevent users from concentrating on their task. We are convinced that TWS-2 has a big advantage over ordinary videophones as a narrowband ISDN service.
