Caller ID
Type II CID
Worldwide Country Support
Both Type I Caller ID (On-Hook Caller ID) and Type II Caller ID (Call Waiting Caller
ID) are supported for U.S. and many other countries (see Section 2.7). Both types of
Caller ID are enabled/disabled using the +VCID command. When enabled, Caller ID
information (date, time, caller code, and name) can be passed to the DTE in formatted or
unformatted form. Inquiry support allows the current Caller ID mode and mode
capabilities of the modem to be retrieved from the modem. Table 2-2 identifies Caller ID
type differences.
Table 2-2. Supported Caller ID Types
Type I CID (On-hook)
Type II CID (Call Waiting)
When connected in V.22bis and Call Waiting is detected (assuming Call Waiting
detection is enabled by +PCW = 0 command), the modem notifies the user of incoming
call by toggling the RI pin. Under similar condition except +PCW = 1, the modem will
hang up. In all other modulations, when +PCW = {0 or 1} and Call Waiting comes in
during data mode, the modem will hang up.
When +PCW = 1 and Caller ID is enabled, the modem will attempt to do Type II Caller
ID before hanging up. The Caller ID information may then be retrieved by issuing
+VRID = {0 or 1} after the modem hangs up.
The modem operates as normal when Call Waiting detection is disabled (+PCW = 2).
However, the modem may also disconnect due to a carrier loss caused by the noise
disturbance that the Call Waiting introduced to the line.
Internal modem firmware supports 64 country profiles (see Section 1.3.3.2). A country
profile can be uploaded via SRAM patch in addition to, or to override, one of the default
countries in the code. These country profiles include the following country-dependent
parameters:
