7 Tone Generation
The modem is capable of generating single or dual tones in the frequency range of 400 to 3200 Hz with a
resolution of 0.15 Hz and accuracy of 0.01%. This feature allows the modem to function as a DTMF dialer.
8 Transmit Level
The transmitter output level is programmable from 0 dBm to - 15.0 dBm and is accurate to
±
1.0 dB.
9 Scrambler / Descrambler
The scrambler and descrambler are in accordance with ITU-T recommendations V.17 ( KS16114 ), V.29 and
V.27ter.
10 Receiver Dynamic Range
The receiver can operate with line signal levels from 0 dBm to - 43 dBm at the receiver analog input
( RXAI ). The RLSD threshold levels are programmable as follows:
Turn on: - 10 dBm to - 47 dBm ( default = - 43 dBm )
Turn off: - 10 dBm to - 52 dBm ( default = - 48 dBm )
11 Receiver Timing
The receiver can track a timing error of up to
±
0.035%
12 Carrier Recovery
The receiver can track a frequency offset up to
±
10 Hz.
13 Received Data
The serial received data output ( RXDO ) is clamped to a constant mark whenever RLSD is off.
14 Tone Detection
The modem features three tone detectors two of which operate in all non - high speed modes. The third
tone detector operates in all receive modes. The three tone detectors can be cascaded to form a single
12th order filter. The filter coefficients of each tone detector are programmable by the host.
