Delay Before Data.
Time the Si2400 waits prior to transmitting data, relative to the end of the handshake
tone.
0 = 300 ms.
1 = Use S2E (RTCT) register contents.
Data Carrier Frequency.
Frequency that the Si2400 will use to transmit.
00 = User programmed. This is accomplished by accessing DSP register 5 prior to using
the !7 command.
01 = 1800 Hz.
10 = 1900 Hz.
11 = 1850 Hz.
Handshake Minimum Time.
The minimum required tone length for a handshake tone or a kissoff tone.
000 = 53 ms.
001 = 160 ms.
010 = 320 ms.
011 = 480 ms.
100 = 640 ms.
101 = 800 ms.
110 = 960 ms.
111 = 1120 ms.
Handshake Frequency.
The frequency that the Si2400 detects as Handshake and Kissoff Tone.
00 = User-defined frequency detectors must be programmed prior to using the !7
command. See DSP Registers.
01 = 1400 Hz only.
10 = 2300 Hz only.
11 = 1400 Hz or 2300 Hz.
