5 DTMF Programming
The CelluLine CGW-T GSM Gateway can be programmed via DTMF. The following steps
describe the procedure:
a. In case the CGW-T is connected to the PBX, remove the cable from the “Trunk”
connector on the unit.
b. Connect an analog telephone directly to the “Trunk” connector on the unit.
c. Dial *900.
d. After hearing the confirmation tone, enter the password (1234 by default).
Notes:
The CelluLine CGW-T will not answer any incoming calls when the analog telephone is
directly connected to the unit.
Exit from the programming mode by *900 or hanging up the telephone.
When you don’t enter digits for 45 seconds, the unit will automatically exit the programming
mode.
When entering an incorrect command, you will hear a beep.
When entering a correct command, you will hear two beeps.
