-
2. Set line voltage to 48V at on-hook condition and line current to 40mA at off-hook
condition of nomal telephone.
3. Execute the command "hookoff"
4. Confirm that the line current is 40mA ± 5mA.
5. Execute the command "hookon".
6. Confirm that the line current is 0mA + 2mA.
1. Connect J1 (Telephone Socket) to DTMF tester.
-
2. Execute the command "hookoff" and "dtmf_up".
3. Confirm that the high frequency (1477.06HZ) group is -6.5dBm ~ -9.5dBm.
4. Execute the command "dtmf_lo".
5. Confirm that the low frequency (852.05HZ) group is -9.0dBm ~ -12dBm.
-
Remove the Antenna before starting step from 1 to 4.
