Caller ID

Off-Hook Intrusion Detection

Voice mode is enabled by the AT command +FCLAS = 8. In voice mode the +VLS command is used to
enable event reporting and tone generation and to control the on/off hook state.
The World Modem™ FAX psupports full type I caller ID and type II caller ID in snoop mode. Caller ID is
supported for the US Bellcore, European ETSI, UK and Japanese protcols and is enabled via the +VCID,
+VCDT and +PCW commands.
The World Modem™ FAX is able to detect when another telephone, modem or other device is using the
telephone line. This allows the host to avoid interrupting another phone call when the phone line is already in
use and to intelligently handle an interruption when the modem is using the phone line.
When the modem is sharing the telephone line with other devices, it is important that it not interrupt a call in
progress. To detect whether another device is using the shared telephone line, the host can use the modem
to monitor the TIP-RING dc voltage with the line voltage sense (LVS) register (U6C, buts 15:8). The LVS bits
have a resolution of 1 V per bit with an accuracy of approximately ±10%. Bits 0 through 6 of this 8-bit signed
two’s complement number indicate the value of the line voltage and the sign bit (7) indicates the polarity of TIP
and RING.
When the World Modem™ FAX is off-hook an algorithm is implemented in the modem to automatically monitor
the TIP-RING loop current via the LCS register (U63, buts 7:0). Upon detecting an intrusion, the modem alerts
the host of the condition via the INT pin. The LCS register has a resolution of 1.1 mA per bit and returns a
zero value if less than the required loop current is present.
