SoftGSM Kit Appendices
MultiMobile SoftGSM User Guide Appendix A - Understanding GSM Introduction This appendix provides background information on GSM standards, data and applications. GSM is a global standard for digital wireless communications, with extensive roaming capabilities for both voice and data services. It has been commercially available since 1992. GSM networks are currently operating in more than 120 countries worldwide which now (December, 1998) includes in excess of 155 million GSM subscribers worldwide.
Appendices Transparent Mode In transparent mode, a non error-corrected connection is established between the user and the remote terminal. Data is then sent asynchronously. Because no error correction is taking place, there is little delay (latency) in transmitting data over the link. Non-transparent Mode In non-transparent mode, a secure error-corrected link is established between the mobile terminal and the remote modem.
MultiMobile SoftGSM User Guide transmissions are encrypted for transmission across the network. This has been a key strength for GSM providing peace of mind for users, without the need for additional expenditure on expensive hardware and software. • Quick call set-up. GSM was developed to interwork with the Integrated Services Digital Network (ISDN). ISDN uses a technique known as rate adaptation to convert the slower GSM data up to 64 Kbps ISDN data 12.
Appendices encrypted. GSM uses special encryption keys, which are synchronized between the Subscriber Identification Module (SIM) card and the GSM network. Most network operators will provide corporate customers with dedicated connection into the corporate LAN, thus bypassing the POTS network, and interconnection charges. If this connection is ISDN, then the benefits of quick call set-up and tear-down can be utilized. • Group 3 Fax.
