1.3.5 Synchronous Access Mode (SAM) - Video Conferencing
V.80 Synchronous Access Mode between the modem and the host/DTE is provided for host-
controlled communication protocols, e.g., H.324 video conferencing applications. Voice-call-
first (VCF) before switching to a videophone call is also supported. 
1.3.6 Worldwide Operation
The modem operates in TBR21-compliant and other countries. Country-dependent modem 
parameters for functions such as dialing, carrier transmit level, calling tone, call progress 
tone detection, answer tone detection, blacklisting, caller ID, and relay control are 
programmable. 
SmartDAA technology allows a single PCB design and single BOM to be homologated 
worldwide. Advanced features such as extension pickup detection, remote hang-up 
detection, line-in-use detection, and digital PBX detection are supported. Country code IDs 
are defined by ITU-T T.35. 
Internal ROM includes default profiles for 29 countries including TBR21-compliant profiles. 
Additional country profiles can be stored in internal SRAM (request additional country 
profiles from a Conexant Sales Office). Duplicate country profiles stored in internal SRAM 
will override the profiles in internal RAM firmware. The default countries supported are listed 
in Table 1-2.
