Displays the dialing method of the operative E&M port. The dialing method refers to the sound that occurs when the user enters each digit of the dialing code. You cannot modify this object. If you want to change the value you must modify the object cxMcVoxEmAdmDialType of the cxMcVox Administrative Driver Group Options: dtmf (1): Dual Tone MultiFrequency uses bursts of frequency pairs to identify the code the user dials. Tones are generated at a level of -7 plus or minus 3 dBm for the lower frequency groups and -5 plus or minus 3 dBm for the higher frequency group. The power level of the higher frequency tone is intentionally increased to compensate for the higher line loss. pulse (2): uses bursts (10 plus or minus 0.5 pps) of the main tone frequency (2280Hz) to generate the codes the user enters. Tones are generated at a level of -4 to -30 dBm for the 2280Hz frequency. The number of pulses during one second indicates the code the user dials. With the E&M interface, the voice station generates and detects pulses. mfR1 (3): R1 signaling protocol MultiFrequency (MF) uses bursts of frequency pairs to identify the code the user dials. Tones are generated at a level of -7 dBm0 +- 1 dB (CCITT Recommendation Q.322). The difference in transmission level between the two frequencies comprises a signal that does not exceed 0.5 dB. mfR2 (4): R2 signaling protocol MultiFrequency (MF) uses bursts of frequency pairs to identify the code the user dials. Tones are generated at a level of -8 dBm0 +- 1 dB (CCITT Recommendation Q.454). The difference in transmission level between the two frequencies comprises a signal that does not exceed 1 dB. Default Value: dtmf (1)
