Note: Be sure to specify a profile number from 1 to 60: <Profile> :INTEGER (1..60) for each parameter under the set voice profile command.

<AnalogOperation>

: twoWire | fourWire

Select either twowire or fourwire operation to match the interfacing PBX.

<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 150 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.

<DigitizingRate>

: G.729-20ms | G.729A-20ms | G.729B-20ms | G.729AB-20ms | G.711-5ms

The value of this object selects the voice digitizing algorithm. (Rate at which voice is digitized designated in bits per second.)

<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>

: time50msec | time60msec | time70msec | time100msec

Specifies the DTMF burst regeneration length in milliseconds.

<DTMFToneDetector>

: disable | enable

When enabled, this feature ensures that DTMF signals are regenerated with a continuous tone. Limited to switched calls, and compatible with other voice/fax modules that incorporate this feature.

<DVMSignalFormat>

: tieTrunk | dc5b | r2Q421 | winkStart

Specifies the voice signaling protocol and format to be used when the DVM channel is connected to a DS0 channel.

<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 | winkStart

Select one of four methods to signal (and sense) the on-hook/off-hook condition of an E&M telephone connection.

DC - 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.

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>

: 2400bps | 4800bps | 7200bps | 9600bps | G.711

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.

<InputLevelGain>

: INTEGER (-15..15)

Used to set the amplification level for the voice/fax input signal. Values range from -15dB to 15dB.

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 (1..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 | complexTBR21 | complexAustralia

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..40)

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. This assures backward compatibility, and requires positive action by the user to enable this feature.

Part of the Single Dial Tone feature.

<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.

<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..15)

Used to set the output voice/fax signal attenuation level. You can enter values ranging from -15dB to 15dB.

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 wherein 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.

<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.

<MinEchoRetLoss>

: zero-dB | three-dB | six-dB

The value of this object specifies the minimum echo return loss.

<EcanDisableMode>

: g164-mode | g165/g168-mode

The value of this object specifies when to disable echo cancellation. Choose g164-mode to disable when 2100hz tone is detected. Choose g165-mode/g168-mode to disable when 2100hz tone with phase reversal is detected.

<EcanDblTalkDetect>

: disable | enable

The value of this object specifies to the voice channel whether to disable or enable the echo canceller to detect double talk.

<EcanHighPassFilter>

: disable | enable

The value of this object specifies to the voice channel whether to disable or enable the echo canceller high pass filter.

<EcanFilterMode>

: disable | enable

The value of this object specifies to the voice channel whether to disable or enable the echo canceller filter.

<FVMInterfaceType>

: fxs-loopstart | fxs-groundstart

The value of this object indicates the interface type for the FXS voice module.

<EnhBckGrndNoiseLvl>

: INTEGER (-40..-60)

Signal input above this level is considered a voice signal. The Voice Activity Detector (VAD) will determine if signals below this level are voice signals or background noise.

<EnhSilenceHngOvr>

: INTEGER (3..50)

Indicates the time delay to switch from voice to silence. This object is incremented in steps of 10msec.

<BRIClockSource>

: internal | external | backplane

Selects the clock source for the BRI voice card on a per expansion card basis parameter. Choose internal (NT mode) to use the module's on-board oscillator as the clock source. Choose external (TE mode) to receive the clock source remotely, such as from a PBX. Choose backplane (NT mode) to use the Passport 4460 unit's master clock as the clock source.

Notes:

1. Changing from TE mode to NT mode and vice versa requires a reset of the Passport 4460 unit.

2. When one of the BRI ports in a 2-Port BVM card (Port A) is configured for TE mode, the other BRI port (Port B) must conform to one of the following:

• Port B can be configured to NT mode using the clock from Port A
• Port B can be configured to TE mode, but the PBX trunk must be synchronized to the clock of Port A

3. Normally, both voice channels belonging to a BRI port should use the same BRIClockSource option, but in the instance of two channels using different profiles, the clock source of Channel 1 takes precedence.

4. Both ports on the 2-port BVM share the same TDM interface, so a single clock source must be used for internal operation of TDM. Clock source is dependent on mode of operation of each port of a 2-port BVM. For specific configuration examples, refer to Voice Services, Configuring a Voice Channel, Voice Profile Options, CLI Procedure for Setting the Voice Profiles (4460), BRI Clock Source.
