CX86500 SCXV.xx Modem Data Sheet
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 pick-up detection, remote hang-up
detection, line-in-use detection, and digital PBX line protection are supported.
Country code IDs are defined by ITU-T T.35.
Internal ROM includes default profiles for 63 countries including TBR21-compliant
profiles. An additional or modified country profile can be loaded into internal SRAM. A
duplicate country profile stored in internal SRAM will override the profile in internal
ROM firmware. Additional country profiles can be loaded into external NVRAM for
permanent storage (38-pin version only). The default countries supported are listed in
Table 1-2. Request additional country profiles from a Conexant Sales Office.
