MultiMobile 53
Chapter 4—Troubleshooting
 In VCOMM mode, use the ATH5 command to check if the ISDN link
between MultiMobile and ISDN switch is ready to make/answer calls.
The following responses report the MultiMobiles status:
Line Lost: ISDN phone line not connected
 Check connection between MultiMobile and ISDN network
connection cable
 Check connection between ISDN network connection cable and
ISDN switch
 Check ISDN switch type setting
SPID Fail: Both SPID numbers are not correctly configured.
1 SPID Ready: One of the SPID numbers is incorrect.
2 SPID Ready: The MultiMobile is ready to operate.
MultiMobile throughput is not as fast as expected.
 Sometimes the resident anti-virus program and the laptops BIOS
settings, such as Auto-detect PNP Function, affect the
MultiMobiles I/O operation and may lower the ISDN TAs file
transfer throughput. Disable them (keep the system as simple as
possible) and try again.
I can run the application successfully, and the MultiMobile
responds OK when entering AT commands, but I cannot
originate/answer ISDN calls.
 Make sure the ISDN phone line is connected properly.
 Make sure the ISDN switch type is selected correctly.
 Make sure SPID numbers are correct.
 Enter ATH5 command (in VCOMM mode) to check MultiMobile
function.
