Annex 2 to AVC-632R

H-series audiovisual terminals in different network environments

Note 1 -	All possibilities of interworking are indicated; some combinations might not be practical.
Note 2 -	Currently H.32X is accommodated both in B-ISDN and ATM-LAN based on the assumption that their UNIs are very similar.  This assumption should be deliberated.

Terminal	Network	Channel bit rate	Interface Protocol	Note	
H.32X	B-ISDN
ATM-LAN	up to several tens Mbit/s	AAL (I.363)
ATM (I.361)
Physical Layer	B-ISDN and ATM-LAN have different physical layers?
