Enabling Auto Hang-Up

Enabling auto hang up enabled allows the system to auto hang up based on loop drop detection.

Enabling DTMF Gain

Enabling DTMF gain enables you to adjust the level of the DTMF digits that are played into the local room

while dialing the telephone interface.

Adjusting the DTMF gain does not adjust the level of the DTMF digits that are sent to the telephone line.

Using Tone Gain

Tone gain adjusts the level of the tones, including the ring tone, that are played into the local room including

the entry and exit tones.

Using Dial Tone Gain

Dial Tone gain adjusts the level of the in room dial tone when the phone is taken off hook.

Using Flash Delay

Flash delay sets the flash timing in milliseconds when the flash feature is executed.

Setting Country Code

The country setting of the telephone interface must be set prior to first use of the telephone line. The country

code only needs to be set once to set the appropriate telephone line interface parameters that are region

Once the country code is set, the phone line may be tested by clicking the phone icon. This takes the

selected phone line off-hook. Assuming the signal routing is correct through the matrix, and the phone line

is connected and active, dial tone is heard in the local room.

Using Line Voltage and Loop Current

The line voltage and loop current are active whenever the Poll Telephony Information is enabled at the top

of the user control. The line voltage and loop current allow for diagnostics of the telephone line. See

Appendix A of this manual for more information on how to query the line voltage and loop current values.
