.

The Nokia 9290 Communicator contains some factory-installed root certificates of popular certification authorities
and Nokia itself. You may wish to get your server certificate from one of these certification authorities, or you can
install a new root certificate to the communicators. Users can freely delete certificates from the device. The certificate
store is contained in ROM and removing the certificate database will revert to factory configuration.

Installation of new certificates is done using a DER encoded (binary) X.509 certificates (PEM or base64 encoding is not
accepted). The user can view the details of a new or already installed certificate, such as the issuer name, subject
name, validity period, serial number, and the fingerprint. The fingerprint can be used to verify the certificate’s
authenticity by out-of-band means.

To find out more about certificates and how they are used in secure communications, please refer to any good
textbook on the subject, for example

2.6 Tested Nokia 9290 compatible PPP access servers

This section contains a list of commonly used PPP dial-in access servers which have been compatibility tested with the
Nokia 9290 Communicator. Another type of PPP server may also work, assuming the server has been configured with
generally used PPP settings such as:

•

The PPP server is capable of establishing data calls using the PSTN/ISDN V.110/ISDN V.120 method

•

The server is able to handle a maximum transfer unit (MTU) of at least 1500 octets

•

Login script authentication with terminal server or PAP/CHAP authentication with PPP server

•

Van Jacobson TCP/IP header compression on/off

•

Dynamically/manually set IP and DNS addresses

•

PPP compression provided by Compression Control Protocol on/off

•

IP packet routing gateway information is set by the PPP server

The configuration options listed above may differ for your local Internet access point. Please contact your local ISP or
corporate information management to get more information about used parameters for your Internet access point.

Compatibility tested PPP servers:

Cisco AS5300

Cisco AS5200

Shiva Access Switch

Shiva LanRover E+

Microsoft NT RAS 4.0

Ericsson Tigris AXC 623

Ascend Max 4004
