POTS Configuration
1.5.4.1 Configuration and Control via DTMF Keypad
Configuration can be carried out at any time by causing the POTS port to go off-hook and then
immediately entering a configuration sequence of DTMF tones. The sequence signalled to the
CMX228 will determine the configuration to be performed, as shown in the following table.

Description
Default
Test watchdog
Puts the CMX228 into a permanent
loop, not updating the external
watchdog counter, so after 2s it should
reset.
Inhibits CLI delivery on the analogue
POTS port
Configures modem standard to be used
for CLI delivery.
