Diagnostics

You can perform additional diagnostics by connecting a 4-pin
RJ-11 connector from the analog telephone to the trunk
connector of your CGW-TS.
To begin diagnostics, pick up the phone's receiver. If you hear:
•
Continuous dial tone: the unit is working correctly and
you can now start to program it.
•
Busy tone: Check which LEDs are lit and find the error in
Section 3.2. You cannot program the unit until you get a
continuous dial tone.
•
No dial tone: The GSM network signal is too low to
complete registration. Remove your SIM card and replace
it with a card from a GSM network that provides a higher
signal level. Enable the roaming parameter (see page 18),
then replace the SIM card with your original SIM card.
Note that all cellular calls you now make from your
CGW-TS will be routed through the alternate GSM
network that you used to complete your registration.
