Reset each I-modem by issuing an ATX! command. Your
new configuration won’t take effect until you do so. Type:
set imodem interface mod:1 at_command ATZ!
When the LEDs start blinking green, an ATI12 command is
sent to the I-modem, responding with a configuration
report. Watch the I-modems’ LEDs closely. They should
follow this pattern:
LED Status State
Blinking Amber (8 per second) Searching for U interface
Blinking Amber (1 per second) Searching for S/T interface
Blinking green (1 per second) Physical connection active
Off Ready to make or receive calls
These are error conditions and suggested solutions:
Blink red (1 per second)
Incorrect SPID. Check the SPIDs
given to you against the ATI12
report sent back by the I-modem.
Solid red
No physical connection. Make sure
the U-interface cable is plugged into
the Telco-ISDN port.
Reminder: Whenever you change any I-modem setting, be sure to
issue AT&W and ATZ! commands immediately afterwards to
save the change and reset the I-modem. For further information
on using the set imodem interface command, see Chapter 9:
Administrative Tools in this manual and the set imodem interface
command in the CLI Reference Guide.
