The communicator also supports PPP Stac LZS Compression Protocol (and its following modes: LCB, CRC,
Sequence Number and Extended Mode) (RFC1974) and Microsoft Point-to-Point Compression (MPPC). To use
these compressions the dial-in system must be configured properly for the usage.
2.4. Secure Authentication and Connections
Secure connections and password protection help to prevent unauthorised access to sensitive information. The
communicator support’s some methods which will secure the authentication. In the PPP authentication the
communicator supports PAP and CHAP.
Third party authentication is one method for protecting passwords, for example, receiving a “one time” password
(e.g., TACACS and RADIUS based systems). In the communicator end, the users only needs to set the password
to be prompted at the Internet Access Point.
There are also some secure connection methods available. One of the most popular is SSL (Secure Socket
Layer). Some banks have established on-line banking over the Internet (i.e. they use an http connection). SSL can
also be used with Lotus Domino. SSL 3.0 software is available for the communicator. See the communicator
support section of Forum Nokia for more information (

3. USING SCRIPTS
This chapter specifies how to define custom login sequences for the time frame between the data call
