the mechanism used for establishing phone connections. Choose from the following:
1.) None – generally, not used.
2.) DTMF/DTMF – for POTS installations with a TRKR on the messenger port.
Incoming and outgoing calls and in‐call DTMF are made via POTS.
3.) AT/AT – Incoming and outgoing calls as well as in‐call DTMF are made via
commands to the TRKR.
4.) AT/DTMF – Incoming and outgoing calls are made via commands to the
TRKR. In‐call DTMF tones are generated.
5.) Reserved – generally, not used.
6.) POTSnoTRKR – Connection to a TRKR not required; no messaging
required. Incoming and outgoing calls are made via POTS. The messenger
port may optionally be connected, for example to MSETManage for MSET
upload.
4.1.8 DTMF Total Time ‐ This is the time for a tone from the start of one digit to the start
of the next. The default value of 1016 works for most applications. To determine the
duration in seconds, multiply the value by 246 uSecs. For example, the default value
of 1016, times 246 uSecs, is 0.25 seconds. (only appears when Dial/In‐call
mechanism enables DTMF)
4.1.9 DTMF Interval Time ‐ This is the duration of the pause between digit tones. The
default value of 407 works for most applications. To determine the duration in
seconds, multiply the value by 246 uSecs. For example, the default value of 407,
times 246 uSecs, is 0.1 second. (only appears when Dial/In‐call mechanism enables
DTMF)
4.1.10 DTMF Output Volume ‐ The volume level of DTMF PWM digit tones, a value from 0
to 127. Default value is 30.
4.1.11 Phones Volume ‐ The volume level of the phones, a value from 0 to 127. Default
value is 50.
4.1.12 Sidetone Level ‐ The sidetone level, a value from 0 to 127. Default value is 0.
4.1.13 Microphone Volume ‐ The microphone volume, a value from 0 to 127. Default value
is 60.
4.1.14 Ringer Volume ‐ The ringer volume, a value from 0 to 127. Default value is 50.
4.1.15 Volume Tap ‐ Select from the following options:
1.) Not Enabled – neither offhook nor flash are enabled
