Snapblue/Snapsoft/Snapcells (SNAP) products are encrypting modem devices designed to transmit and receive encrypted calls over a GSM network. The transmission is routed over the network using CSD (circuit switched data) Asynchronous Data at 9600/14,400 BPS. This is not GPRS or EDGE data (refer to diagram on page 3 for illustration). The SNAP products are designed to automatically detect the proper network settings for transmitting encrypted information over the network using CSD. The setting for CSD can be adjusted by within the connection settings. There are two types of CSD protocols in the SNAP products (V.32- Analog and V.110-Digital).
