Appendix E. Modem Configurations
The service processor is designed to place little demand on the attached modem,
thereby increasing the setup and connection success rates.
Sample Modem Configuration Files
Several sample modem configurations files are supplied that either work directly with
your modem, or provide a good starting point for a custom setup, if required. These
files are included on the Sample Modem Configuration Files diskette and in your
Service Processor firmware with the following names:
Diskette File Name Service Processor Firmware File Name
modem_z.cfg modem_z.sp
modem_z0.cfg modem_z0.sp
modem_f.cfg modem_f.sp
modem_f0.cfg modem_f0.sp
modem_f1.cfg modem_f1.sp
modem_m0.cfg modem_m0.sp
modem_m1.cfg modem_m1.sp
The sample modem configuration files are located in the /usr/share/modems
subdirectory, if your server is using AIX. A listing of each file is included at the end of
this appendix.
