4.4.78
S77 – Pre-Dial Call Progress Precise Detect Level
(Default = 30)
S77 determines at what minimum level precise call progress tones are detected before dialing. Range is 1
to 96. (a larger value corresponds to a lower signal level). The default value translates into –45dBm. The
dBm level depends on the DAA used. The range is –25 to –45dBm. Refer to table under S78.
4.4.79
S78 – Post-Dial Call Progress Precise Detect Level
(Default = 30)
S78 determines at what minimum level precise call progress tones are detected after dialing. Range is 1
to 96. (a larger value corresponds to a lower signal level). The default value translates into –45dBm. The
dBm level depends on the DAA used. The range is –25 to –45dBm.
4.4.80
S79 – FSK Originate Carrier Detect Level
(Default = 35)
S79 determines at what minimum level carrier is detected for originating FSK. Range is 1 to 96. (a larger
value corresponds to a lower signal level). The range is –25 to –45dBm.
4.4.81
S80 – FSK Answer Carrier Detect Level
(Default = 35)
S80 determines at what minimum level carrier is detected for answering FSK. Range is 1 to 96. (a larger
value corresponds to a lower signal level). The range is –25 to –45dBm.
4.4.82
S81 – DPSK Originate Carrier Detect Level
(Default = 40)
S81 determines at what minimum level carrier is detected for originating PSK. Range is 1 to 96. (a larger
value corresponds to a lower signal level). The range is –25 to –45dBm.
4.4.83
S82 – DPSK Answer Carrier Detect Level
(Default = 35)
S82 determines at what minimum level carrier is detected for answering PSK. Range is 1 to 96. (a larger
value corresponds to a lower signal level). The range is –25 to –45dBm.
4.4.84
S83 – QAM Originate Carrier Detect Level
(Default = 40)
S83 determines at what minimum level carrier is detected for originating QAM. Range is 1 to 96. (a
larger value corresponds to a lower signal level). The range is –25 to –45dBm.
4.4.85
S84 – QAM Answer Carrier Detect Level
(Default = 35)
S84 determines at what minimum level carrier is detected for answering QAM. Range is 1 to 96. (a
larger value corresponds to a lower signal level). The range is –25 to –45dBm.
