Specification Continued:

By detecting ring OR line reversal signal as the start of the Caller ID sequence, the

GaneData USB device is able to work with all of the FSK data formats i.e. US FSK,

ETSI FSK and BT FSK.

There are minor differences between the FSK types as to how the data is formatted.

However, GaneData USB device does not try to interpret the data received from PSTN.

It checks the data for errors by using the checksum and passes the received data to PC

without any modification. In this way, any differences between the FSK types can be

resolved with the application running on the PC.

The GaneData USB detects and reports on only the Caller ID information on the

telephone line.

Hardware:

The GaneData USB is powered from the USB interface. When the unit is connected to

the USB port the one of the Red LED turns'ON' to indicate that the unit has been turned

on. While receiving a call, the Green LED blinks to indicate information being received

and sent to the USB. This Green LED will also blink when information is written to the

virtual COM port. This can be a useful diagnostic, e.g. to check that the service has

actually been switched on by BT, or that the telephone line is connected.

Specification of Data:

The serial data is presented at a baud rate of 1200, with 1 start and 1 stop bit. The data

is sent whenever there is activity on the telephone line. The GaneData USB does not

receive any data from the PC.
