| Object | Parameter | Description |
|---|
| <AnalogOperation> | : twoWire | fourWire | Select either twowire or fourwire operation to match the interfacing PBX. |
| <AutoGainControl> | : disable | enable | Choose enable automatic level enhancement to boost weak DTMF and voice signals above the noise threshold to a minimum usable level. |
| <Background> | : regenerated | silence | Determine whether users hear silence or regenerated background noise when no signal is being sent across the line. |
| <Bandwidth> | : voiceActivated | continuous | Select voiceActivated where the voice/fax channel uses bandwidth when speech or fax signals are present. Select continuous where the voice/fax channel uses bandwidth for the entire time that the channel is in use. You may use this option if you want to transmit background noise or music while on hold. |
| <BusyOutMode> | :systemControlled | forcedOn | forcedOff | Select systemControlled to place the voice/fax channel in a busyout state during link outages of 40 seconds or more, or when there is not enough bandwidth available to support the voice/fax channel. Select forcedOn to force the voice/fax channel into the busyout state. Use to disable an intermittent or defective voice/fax channel until it can be repaired. Select forcedOff to prevent the channel from going busy, even during link outages or congestion. Use when testing the channel. |
| <CallProgressTone> | : northAmerica | japan | unitedKingdom | europe | france | centralAmerica| chile | australia | Matches the call progress tones to one of eight countries or areas where the network is installed. The Call Progress Tone table in Appendix C shows details for each selection. |
| <CompanderFormat> | : uLaw | aLaw | A voice encoding/decoding scheme of PCM associated with this T1/E1 type transmission. This parameter tells the DVM channel how to encode/decode the CAS coming from the T1/E1 line. |
| <RegenDelayHighReso> | : INTEGER (1..150) | Select the delay regeneration interval. Defines compensation time before the remote PBX goes off-hook and provides a dial tone back to the voice channel for completing the call setup. (range 1 to 10 seconds) Part of the Single Dial Tone Feature. |
| <DialDigTimeLimResot> | : INTEGER (1..150) | Specifies the maximum time (from the start of one digit to the start of the next) for accepting dialed digits. When the time limit is reached, further digits are not accepted, and the accumulated digits are forwarded to the remote voice channel. This allows a person time to pause and check a number being dialed. When using pulse dialing, the parameter must be set for 2 seconds or more to accommodate the high-order digits, such as 9 or 10. Part of the Single Dial Tone Feature. |
| <DiscSupervision> | : tone | powerInterrupt | Selects the detection method used when the telephone equipment attached to a voice/fax port goes from an off-hook (active) to an on-hook (idle) state. Select power Interrupt - where the voice/fax channel monitors the station line of the PBX or CO for the absence of loop current for 600 ms or longer. Select tone - where the attached PBX or CO cannot supply a power interrupt signal, the voice/fax channel looks for a call progress tone of 600 Hz or less. |
| <DtmfGenBurstLen> | : time50msec | time60msec | time70msec | time100msec | Specifies the DTMF burst generation in milliseconds. |
| <DtmfDetRegBurstLen> | : disable | enable | Specifies the DTMF burst regeneration length in milliseconds. |

Limited to switched calls, and compatible with other voice/fax modules that incorporate this feature. |
| <DVMSignalFormat> | : tieTrunk | tieInvert | clearChannel | dc5b | dc5bInvert | r2PUNCOM | r2Q421 | israelCAS| spainCAS | winkStart | Specifies the voice signaling protocol and format to be used when the DVM channel is connected to a DS0 channel. |
| <EcanEr1Improvement> | : INTEGER (-18..0) | The value of this object is used for echo canceller Er1 improvement for the ISDN BRI voice card. A signal will be attenuated by the dB amount specified before being passed through the echo canceller. After it is passed through the echo canceller, it will be amplified by this same dB amount, for a net gain of 0 dB. This attenuation amplicfication cycle reduces the resolution of the signal ( -18 ..0 ). |
| <EcanFilterLen> | : 128length | 256length | The value of this object specifies the filter length for echo canceller. This is a permanent DSP configuration parameter. 128length is equal to 16ms. 256length is equal to 32ms. The ISDN BRI voice card supports 32ms only. |
| <EchoCanceller> | : disable | enable | Used to enable or disable the echo canceller. Set to enable during normal operations. Set to disable when performing external tests, or when using an external echo canceller. |
| <EMSignalFormat > | : dc | tone2280 | pulsedDC | winkStart | Select one of four methods to signal (and sense) the on-hook/off-hook condition of an E&M telephone connection. Where dc is selected, the channel senses the active/idle condition of the remote end by the DC level on its M lead, and signals to the remote end its active/idle condition by a DC level on its E lead. Where tone2280 is selected, the channel senses the idle condition of the remote end by the presence of a 2280-Hz tone on its T-R pair, and holds a 2280-Hz tone on its T1-R1 pair to indicate its idle condition to the remote end. This option is applicable only to 4-wire connections. Where pulsedDC is selected, the channel senses the transition from on-hook to off-hook by a pulse of medium duration, and the transition from off-hook to on-hook by a pulse of longer duration. Both ends of the connection must select this signaling format. winkStart - In the originating channel the user enters a string of digits to reach a distant PBX station. The originating PBX first seizes the M lead and waits for a wink signal response from the local voice/fax channel. Only then does the local PBX forward the dialed digits to the destination voice/fax channel. At the destination end, the voice/fax channel seizes the E lead and starts a (regeneration) delay timer. When the delay timer expires, the remaining digits are forwarded to the destination PBX. |
| <EndOfDialCharStatus> | : disable | enable | Used in conjunction with the Single Dial Tone operation. When enabled, receipt of a # sign following a string of digits will cause the voice channel to forward all digits immediately, without waiting for the accumulation of the maximum number of forwarded digits or for the dial digit time limit to expire. |
| <FaxDigitizingRate> | : voiceRate | 2400bps | 4800bps | 7200bps | 9600bps | Selects digitizing rates for fax/modem signals. Normally, separate fax digitizing rates are used. If Voice Rate is selected, the digitizing rate for fax/modem signals will be limited to 7.2 kbps. |
| <RegenerationFormat> | : dialPulse | dtmf | Used to allow the voice/fax channel to match the outgoing dialing digits with that of the interfacing PBX. Dial Pulse-used when the interfacing PBX requires that the incoming dialing digits be in a dial pulse format. DTMF -used when the interfacing PBX requires that the incoming dialing digits be in a DTMF format. |
| <FXSSignalFormat > | : repeatedRing | interruptedRing | Used to set the ringing cadence for the FXS interface. Interrupted Ring - The ringing cadence is: ring for two seconds, off for four seconds. Repeated Ring - In which the ringing cadence is slaved to the ring cycle generated by the PBX. |
| <InputLevelGain> | : INTEGER (-15..19) | Used to set the amplification level for the voice/fax input signal. Values range from -6dB to 19dB. Note: The input level gain must be set to 0 dBm for equipment operated in the U.S.A. or Canada. If your equipment is operated outside of the U.S.A. or Canada, follow the standards of the country where the equipment is used. |
| <IdlePattern> | : INTEGER (0..255) | The value of this object represents the idle pattern on the line when there are no calls. This is specific to a PBX. This is a permanent DSP configuration parameter. This value can be used to detect that a call has finished, the echo canceller should be reset and that fax mode should be terminated. |
| <Jitter> | : INTEGER (0..200) | Used to set the time (in milliseconds) required to compensate for the delay of transmitted voice packets across a network. This setting provides compensation for the difference between arrival time and expected arrival time of voice packets, maintaining continuous voice delivery. Values range from 1 to 200 milliseconds. |
| <LineImpedance> | : 600ohms | complex | Used to set the line impedance options for the FXS, FXO, and E&M 2-wire. Line impedance of the E&M interface configured for 4-wire operation is fixed at 600 ohms and is not configurable. |
| <MaxNumFwdDigits> | : INTEGER (0..36) | Used to specify the maximum number of dialing digits, ranging from 0 to 40, to be forwarded to the attached PBX. If this number is reached, the accumulated digits are forwarded without having to wait until the Dial Digit Time Limit is reached. Default value is 7, which will disable the Single Dial Tone feature. This assures backward compatibility, and requires positive action by the user to enable this feature. Part of the Single Dial Tone feature. |
| <MaxOutputLevel > | : 0dBmNominal | plus7dBm | Used to set the maximum output level to be used with a voice channel configured for 4-wire E&M. 0dBmnominal - used for all other applications. plus7dBm - use when the interfacing tie trunk equipment includes a pad. |
| <Mode> | : voiceFax | voiceOnly | Sets the voice channel to voice/fax, or voice only operation. voice/fax operation - The voice channel will process voice, fax, or modem (data) signals. Normally, the channel will operate in voice mode. If a fax or data signal is detected, and there is no voice traffic over the channel, the channel will automatically switch to either the fax or modem mode. It will stay in that mode until fax/data signals are no longer detected, and then switch back to voice mode. Use this option for most voice/fax/modem applications. voice only operation - in which the channel will remain in voice mode all the time. Use this option if the voice/fax channel is dedicated to voice traffic only. You must select this mode when performing frequency/level tests of the channel. This prevents the channel from accidentally entering the fax mode when a test tone is used. |
| <BckGrndNoiseLevel> | : neg25dbm0 | neg30dbm0| neg35dbm0 | neg40dbm0| neg45dbm0 | Signal input above this level is considered a voiced signal. Anything below this level, the Voice Activity Detector (VAD), will determine if it is a voiced signal or background noise. |
| <NoiseFloorOffset> | : INTEGER (0..255) | The value of this object will suppress the impulsive backround noise in order to achieve silence suppression savings. |
| <NumOfRings> | : INTEGER (1..9) | Used to set the number of ring cycles a local FXO channel will wait before providing a dial tone. When an attempt is made to contact a network channel from a PBX station, the user first dials the local FXO channel and waits for a second dial tone. In response, the local FXO channel waits one or more ring cycles before providing that dial tone. The user then dials the extension number of the network channel. |
| <OutputLevelAttn> | : INTEGER (-15..25) | Used to set the output voice/fax signal attenuation level. You can enter values ranging from 0dB to 25dB. Note: The output level attenuation must be set to 0 for equipment operated in the U.S.A. or Canada. If your equipment is operated outside of the U.S.A. and Canada, follow the standard of the country where the equipment is used. |
| <PremiumVoice> | : disabled | enabled | When enabled, this object selects whether the DVM channel should perform the voice compression/decompression coming from or going to the T1/E1 DS0 channel. |
| <PulseRate > | : 10PulsesPerSecs | 20PulsesPerSecs| 125PulsesPerSecs | Defines the maximum number of pulses per second which may be generated or received in an E&M interface-type channel. For a standard E&M channel, the value must be set to 10. For partner BRI channel, a larger number should be used to speed up the communication. |
| <RingFrequency> | : 25Hz | 50Hz | Used to set the frequency of the signal that causes an attached telephone to ring when a call is coming in on that channel. 25 Hz - used for most applications. 50 Hz - used with some European telephone systems. |
| <SilenceHngOvrTime> | : msec100 | msec200 | msec300 | msec400 | msec500 | msec600 | msec700 | msec800 | Indicates the time delay to switch from voice to silence. Units listed in milliseconds. |
