The V-There™ video conferencing system developed by ClearOne comprises a set-top

unit with a user-friendly software interface. Each screen in the V-There software can

be easily navigated using the specially designed handheld remote control or

keyboard.

V-There’s main function is the making and receiving of video conference calls.

V-There supports the H.320 (2100 and 2200 models only) and H.323 standards,

enabling you to make the following call types: Integrated Services Digital Network

(ISDN), 56K Restricted ISDN (ISDN-R, line rates in 56K multiples), local area

network (LAN), local area network-wide area network (LAN-WAN), and voice.

During H.320 ISDN and H.323 LAN calls, you can use V-There’s integrated

web browser to access Internet access and to exchange images or a sequence of

images with the person on your video call. This enables you to share web pages

and documents and make presentations while in a call.

The included AccuMic™ II delivers clean, high-quality conferencing audio

with Gentner

Distributed Echo Cancellation®, noise cancellation, and wide-

bandwidth digital audio technology.

Introduction ~ Using This Manual

To find information on a particular topic, consult either the table of contents or the

index. To obtain the definition of a term used in this manual, consult the glossary at

the back of this manual. To begin using V-There immediately, consult the Quick Start

Guide supplied with your V-There.

Scope of the manual

This manual deals with the operation of the V-There unit and its associated software.

Terminology

This section lists some of the terminology used in this manual and defines how these

terms are used within the context of the V-There.

Icon

The word icon always refers to an element on the V-There interface that you can

highlight and select.

Highlighting

Highlighting an icon or option on a drop-down list involves using the arrow buttons

to move the white box on the screen to the field, check box, or drop-down list that

you want to edit. Once you have highlighted the item you want, you usually have to

select it as well. For example: To add a new entry to the Phone Book, highlight and

select the Add icon.

Selecting

Pressing the Enter remote control button confirms the option or icon you have

highlighted and executes the required action. For example: Highlight and select the

Place a Call button in the interface. The Place a Call screen is displayed.

Getting Started ~ Positioning the V-There

Before using the V-There, please read the enclosed end user license

agreement—it contains important information concerning your use of the V-There

software. If you have the 2100 or 2200 model, please read the section on ISDN.

North American users

This equipment uses an S/T interface and is designed to connect to an external NT-1

terminal adapter (or optionally an NT-3, if you are using all three ISDN lines with a

V-There 2200). If your ISDN switch supplies a U interface, an external NT-1

terminal adapter must be used. Please contact your ClearOne distributor for

information about acquiring an external NT-1 or NT-3.

ClearOne Communications ~ www.clearone.com

ClearOne is not responsible for product damage

incurred during shipment. You must make claims directly with the carrier.

Place the V-There main unit on a flat hard surface that allows adequate airflow

through the ventilation holes. Do not place the main unit in direct sunlight or near

sources of direct heat.

We recommend that you place the V-There on top of the video monitor. This

gives a more natural appearance to a video conference, since you will remain in

the line of sight of the camera. You will also be able to view the video image of the

person you are calling, without adjusting your position.

You can position the camera up to five meters (16.5 feet) away from the

V-There unit. Refer to page 17 for information about installing the camera

remotely.

The difference between the

V-There 2100 and 2200 is

that the 2200 features a

higher H.320 data rate (64384kbps vs. 64-128kbps). The 2000 model supports only H.323, not H.320.

✍

Before you can begin using your V-There, you must connect the V-There to the

following:

• Power supply

• Monitor

• Microphone

• Audio speakers

• LAN and/or ISDN (w/ISDN interface)

• Camera w/infrared receiver (if the camera is being installed remotely)

Positioning the V-There

Before You Install

V-There uses an S/T ISDN

interface, requiring an

NT-1 or NT-3 adapter if your network uses a U interface. You can purchase an NT-1 or NT-3 through your ClearOne dealer.

✍

Page 13

Getting Started ~ Hardware Setup

All connections are made at the back of the V-There. The diagram above shows the

rear panel connections for the V-There 2200 model. For the 2100 model, the only

difference is that there is only one ISDN connector. The 2000 model has no ISDN

connector.

Before you begin to connect your V-There, ensure that the on/off switch is in

the Off state (down) and that the power supply has been connected to V-There.

The table below describes the purpose of each of the connectors on the rear

After you have finished making connections to the rear panel of the V-There, turn it

on using the switch on the back of the unit. The first time you power on the unit (or

after you reset the unit to factory defaults), it will initiate an onscreen configuration

wizard that walks you through the system setup.

You do not need to complete every step to begin using your V-There. For

example, if you choose to use your ISDN connection in the configuration wizard,

and will not be connecting the unit to a LAN, you do not need to complete the

configuration screens for network (LAN) setup.

After you complete the configuration wizard, you can make subsequent

adjustments in the Expert Mode of the user interface. To enter the Expert Mode,

press the Expert/Novice Mode button on the keyboard to display Expert System

Setup.

There are several occasions when you will use the Expert Mode:

• When you turn on your V-There for the first time

• After a software upgrade

• After resetting the V-There to factory defaults

• To add or edit phone directory entries or presentations

CHAPTER 5: Configuration

ClearOne Communications ~ www.clearone.com

Configuring V-There

The first time you turn on

your V-There, it will

initiate an onscreen configuration wizard that walks you through the initial system setup for the network, gatekeeper, and ISDN.

✍

Refer to the sections on the

following pages after the

initial setup if you want to change settings, or if you want information about additional settings not covered in the configuration wizard.

✍

Page 28

ClearOne Communications ~ www.clearone.com

Configuration ~ LAN Setup

LAN setup is required if you want to make H.323 calls, use the browser, or remotely

access the unit for administration and troubleshooting.

Optimal settings for LAN calls

The V-There requires appropriate settings on the network switches and hubs used for

H.323 LAN calls. For a 384kbps LAN call, V-There will require more than 800kbps of

LAN bandwidth (400kbps in each direction) due to overhead on packets. Equally

important is that packets must be delivered with minimum jitter and delay. The network

administrator can take several steps to optimize the performance of LAN calls:

•

Proprietary bandwidth control techniques on hubs and switches should be

turned off—they can reduce traffic on high usage ports.

•

Use switches rather than hubs, if possible—switches increase throughput.

•

Ports used for V-There should be configured as 10Mbit full duplex. Auto-sense

of duplex should be disabled.

•

Any proprietary packet forwarding algorithms designed to improve file transfer

and conventional IP usage should be turned off—LAN video calls need simple,

real-time packet delivery.

•

Good quality Cat. 5 cable should be used. Poor quality cabling will not cause

problems with normal operations as packets are re-sent, but on a LAN call,

lost packets will show up as blocky video or audible noise.

•

The network segments being used by V-There should not be heavily loaded with

other network traffic.

Video quality on the first call

During the first LAN call after initial setup, the V-There will attempt to detect the

half/full-duplex setting of the connected switch or hub. It looks for errors on the

Ethernet line. As errors can occur with the correct duplex setting, the V-There

measures them over a period of time, switches its duplex mode, and re-measures the

error rate. It then selects the best duplex setting. For this reason, the first LAN call on

a new installation should be left up for three minutes if the video quality looks poor.

The V-There is factory set to use half-duplex.

The unit monitors packet loss during the first call after each power-up. If packet

loss is excessive, the V-There will switch duplex settings and re-check the packet loss. If

the new duplex setting reduces packet loss, the new setting is retained. Under normal

circumstances, the second power up on the same hub results in minimal packet loss.

LAN Setup

LAN setup is not required if you will use ISDN exclusively.

✍

Page 29

ClearOne Communications ~ www.clearone.com

Configuration ~ LAN Setup

Required information

Before you begin the LAN setup, it is recommended that you connect your V-There unit

to your LAN using the Ethernet (marked LAN) cable.

Network settings

To use V-There over a LAN, you need to know if the LAN uses Dynamic Host

Configuration Protocol (DHCP).

If the LAN does not use DHCP, you need the following information prior to LAN setup:

• The IP address to be assigned to the V-There

• The subnet mask

• The IP address of the default gateway

• The IP address of the Domain Name System (DNS) server, if you want to use a

DNS server for name lookup

• The IP address of the Windows Internet Naming Service (WINS) server, if you

want to use a WINS server for name lookup.

To configure LAN (DHCP)

1. If you are not in the Expert Mode, press the Mode key on the keyboard to

display the Expert Mode menu.

2. Click the Expert System Setup button (first menu button). This displays the

configuration toolbar.

3. Click the Adjust Communications Settings button. This opens the

If you do not use a gateway, these fields can remain blank.

Required information

Before you begin the ISDN setup, it is recommended that you connect your V-There

unit to your ISDN connection using the supplied ISDN cable(s). The number of

cables that you need will depend on the number of ISDN channels that are available

to you and are supported by the V-There model. You will need one ISDN cable if you

are using the 2100 model and up to three if you are using the 2200 (ISDN cables

are included with these models).

The following section lists the information required for completing the ISDN

Settings screen:

• The type of ISDN exchange (or switch type) to which V-There is to be connected

• The local ISDN numbers for the lines to be used. These must be entered in the

proper order.

• Whether the ISDN network is restricted to a multiple of 56K (ISDN-R, nx56K)

• SPID information

• Any prefixes or other specialized information to access long-distance calling on

single channels. Each line is 64kbps. You can dial a call with a rate of 1x64kbps, 2x64kbps, and so on, up to 6x64kbps. When making an unbonded call, you need to enter an ISDN number for each ISDN line you are using.

✍

An ISDN-R call is

transmitted at a rate that

is a multiple of 56kbps. This rate is used in some countries where channel bandwidth is limited to 56kbps. An ISDN-R call can also be bonded.

The H.320 Calls and H.323 Calls fields specify the compression algorithm to

be used when making an ISDN or LAN call. The default setting for both fields is

Auto Select.

ClearOne recommends that you do not change these settings because Auto

Select enables the unit to detect automatically which compression algorithm is

most suitable for a particular call type. If you select one of the other compression

algorithms, the V-There attempts to use it. If the codec at the far end doesn’t

support the algorithm, the V-There automatically selects a compatible algorithm.

canceller in a conferencing system that does not have any other echo

canceller. The echo canceller is available only if you selected Line in the

Audio Source menu (default is Off). Do not enable the echo canceller if

you are using the AccuMic II mic pad included with your V-There. The

AccuMic II already includes echo cancellation; enabling the V-There’s echo

canceller will result in audio problems due to conflicts between the echo

cancellers.

2. The Line/Mic Input gain slider is used to adjust the degree of gain or

amplification applied to the line or mic input signal. The input’s relative

gain value in decibels is displayed in the box to the right of the slider.

If you are using the AccuMic II included with your V-there, ClearOne

recommends that you do not change this value, since higher values make the

V-There more sensitive to audio input and might adversely affect echo

cancellation. If you choose to use a different microphone, you might need to

adjust the input gain value accordingly.

3. Adjust the Line Output slider to set the audio level you want to use in your

conference. This is best accomplished by conducting a test call and adjusting

the level during the call.

Below each slider is a meter that references the level of the input or output.

Figure 5.11 Audio Gain screen

All of the settings on the Video Setting Preferences screen are set to optimize video

transmission when using the camera supplied with your V-There. The original setting

on each slider on the screen is at or near the middle of the scale. If you decide to

change any of the video settings, you can return to the original settings by moving

the sliders back to their original position in the middle of the scale, or by resetting

V-There to factory settings. For information on how to reset V-There, see

Dual Monitor

Dual Monitor is used if you want to use two monitors for different video sources—for

example, you can route local video to a VGA monitor and far-end video to a

television.

Dual monitor mode is particularly useful if you want to run the web browser,

share single images, or use presentations during a call.

To use dual monitor mode, you must ensure that one VGA and one

composite/S-video monitor are connected to the unit. You cannot use dual monitor

mode if you have only one monitor connected to your unit.

During a call, the composite monitor displays the video image while the VGA

monitor displays a graphic, presentation, or the web browser. This is a default

setting and cannot be changed. You can also use the VGA monitor to access the

V-There Menu screen.

When you are not in a call, the Main screen is displayed on both monitors.

The text “Dual Monitor Mode” is overlaid on the picture-in-picture (PIP) display

to remind you that the Dual Monitor Mode check box is selected.

During power-on, V-There detects whether or not a VGA monitor is connected.

You cannot select Dual Monitor Mode unless a VGA monitor is detected.

When Dual Monitor is activated, the Adjust Video Settings screens are

disabled during a call since changing the settings on these screens would disrupt

the transmission.

Auto Display Snapshot

This feature, if enabled, automatically displays video “snapshots” sent from the far

end camera. If you do not have this feature selected, you can press the Snapshot

button on the remote control or keyboard to display incoming images (you will be

notified by an onscreen message that an image has arrived).

Loop Back

A loop-back call is a call in which the unit calls itself. This is useful for testing if the

unit is capable of receiving and transmitting voice, audio, and video data correctly.

If you are having problems with an outbound call, the problem is likely with

your ISDN configuration, even though a loop-back call indicates that the unit is

working correctly. You can check your ISDN settings on the ISDN Settings screen

to ensure the settings are correct. If these appear to be in order, the problem might

be with the ISDN network.

To initiate a loop-back call

1. Select the Type and Rate of the call from their respective drop-down lists.

2. Click Call. The unit initiates the loop-back call.

3. Press Hang-Up to end the call.

If there are problems with any settings during the call attempt, you will be notified.

Figure 5.17 Troubleshoot screen

Some gatekeepers might prohibit the V-There from

making a LAN loop-back call. The function of a gatekeeper is to verify the destination address of a call prior to allowing the call to proceed. Since the originating number and destination number of the loop back call will be identical, the gatekeeper might not be able to recognize a loop back call.

This chapter describes how you can use V-There to access files on a PC, LAN, or

PCMCIA flash card and send a single image or a sequence of images to the person

you are calling. This enables you to make presentations and share documents and

web pages during a call.

There are three options for sharing visual information: snapshots from the local

camera, MicroSoft

-based presentations (PowerPoint®, Word, and Excel files), and

web pages. Before sending a file, you must ensure it is in HTML format. V-There can

access files from an intranet server, web server, or flash card using the browser. See

page 52 for information about the browser.

To access files on a PCMCIA flash card, you must first install the card with the

presentation(s) you want into the slot on the back of the V-There (see below).

The PCMCIA slot at the back of the V-There has a plastic cover that can easily be

removed, and put back when you have finished using the flash card.

CHAPTER 7: Sending Data

that an Annex D image has been received. The Image Received icon is displayed.

If you choose to view the image, the video image of the person you are calling

will freeze for a few moments while V-There decodes the Annex D image. If you

choose to discard the image, the image is deleted and cannot be retrieved.

If you receive an Annex D image while using your V-There in dual monitor

mode, the Annex D image is automatically displayed on the VGA monitor, while the

video image of the person you are calling is displayed on the composite monitor. If

you receive an Annex D image while using your V-There in single monitor mode, the

Annex D image will temporarily replace the video image on the monitor. To return to

viewing the video image, press the Snapshot button. The video image of the party

you are calling is displayed again and the Annex D image is discarded.

It takes several seconds to send an Annex D image, especially during a low

bandwidth call.

Sending Data and Images ~ About the Web Browser

If you have set your V-There to use dual monitor mode, you can use the browser

during a call to share a web page with the person you are calling, or to send a single

image or presentation. The person receiving the call does not have to have his

V-There in dual monitor mode. Any teleconferencing unit that supports the Annex D

format can share web pages and receive images sent by V-There.

The V-There browser can display the majority of web sites. However, it does

not support sites containing Java or VBScript or multimedia plug-ins.

Navigating the web browser

The V-There web browser is very similar to most browsers and consists of a menu

bar, an Address field, and a toolbar. You can navigate with the browser in the

same way you would with any web browser—by pressing the arrow buttons to

move the cursor around the screen.

To select a hyperlink or press a button, simply point the cursor at the

hyperlink or button and press the Select key.

Menu bar

The toolbar contains four buttons: Forward, Backward, Stop, and Refresh. Each

menu contains several menu options. To select a button, point the cursor at the

button and press the Select key.

The web browser cannot be used during LAN calls.

✍

About the Web Browser

To send a presentation

1. Select the Make a Presentation button in the Express Mode screen and press

Appendix B ~ ISDN Error Codes

When a call fails to connect or it terminates, V-There generates an error. The error

codes are specified in ITU-T specification Q.850 as “cause codes.” V-There displays

a brief summary of the information in Q.850. The following paragraphs expand on

the summary displayed on screen. Possible remedies are suggested.

Whenever V-There returns an error in trying to connect a call, two checks should be

made before referring to the detailed messages:

• Check that the number dialed is correct and includes any required PBX

prefix, international or long distance access codes and, for international

numbers, omits the foreign long distance prefix.

• Check that the switch setting in the ISDN Settings screen matches the

switch to which the V-There is connected. In the case of US switches,

ensure the SPIDs are correct. After changing the switch type, it is

sometimes necessary to power down V-There—this depends on the vendor of

the ISDN PBX or telecom supplier.

The cause codes are divided by the ITU-T into classifications to assist understanding

of the seriousness of the cause. These classifications are used below. All cause codes

not listed are invalid and should never be returned. If they are, V-There displays

“Invalid Cause Code (xx)” where xx is between 0 and 255.

Normal causes

These occur in normal operation and are usually capable of being remedied by user

actions.

Cause 01: Unallocated number (Cause 01)

This indicates that, although the number is a valid format, it has not been allocated

by the telephone company. Either the person being dialed has been cut off or the

number is incorrect.

Cause 02: No route to specified transit network (Cause 02)

This means that the call was placed by specifying a routing of networks. The most

likely reason is that V-There is attached to a local PABX, which attempts to route

calls using a “cheapest” route method, which is currently unavailable.

Appendix B: ISDN Error Codes

Page 61

ClearOne Communications ~ www.clearone.com

Appendix B ~ ISDN Error Codes

Cause 03: No route to destination (Cause 03)

This means that the destination number is not supported by the PABX/Telephone

system connected to V-There. The most likely reason is that there is a mistake in the

dial string (forgetting a PABX prefix for an outside line).

Cause 06: Channel unacceptable (Cause 06)

This means that the local PABX/ISDN provider does not accept the channel that

V-There has attempted to dial on.

Cause 07: Call awarded and being delivered (Cause 07)

This means that the call has been delivered on an existing channel at the far end. As

this is highly abnormal in ISDN environments it suggests a configuration problem

with the far end.

Cause 16: Normal call termination (Cause 16)

This is a normal situation. If the termination is not what is expected, then the

network is providing no additional information. Check the ISDN settings carefully as

well as the numbers dialed.

Cause 17: User busy (Cause 17)

Some long-distance carriers require a prefix for the ISDN number you are dialling.

If it isn’t entered properly, you’ll get a busy tone. This means the far end system is in

a call. Simply try again later. If it is known that the far end is NOT in a call, then

the far end unit should be power cycled as it might be holding the line open for some

reason.

Cause 18: No user responding (Cause 18)

There are two common reasons for this: the far end is switched off or it is in a

“manual answer” mode and there is no one to answer the call.

Cause 19: No answer from user (Cause 19)

This is almost the same as Cause 18. The major difference is that Cause 18 is more

commonly returned when the far end is switched off whereas this message is more

commonly a case of a “manual answer” system with no one to take the call.

Cause 21: Call rejected (Cause 21)

This means either that the user has deliberately rejected the call (V-There systems do

not do this – they return a “normal termination” when a user rejects a call). Or, this

occurs when the far end network has rejected the call—for example, when a PABX

rejects incoming calls.

Page 62

ClearOne Communications ~ www.clearone.com

Appendix B ~ ISDN Error Codes

Cause 22: Number changed (Cause 22)

This means that the telephone company has changed the far-end number; you need to

find the new number for the system.

Cause 26: Non selected user clearing (Cause 26)

This is an unusual cause, which means that the network cannot connect the call but

cannot give any more information.

Cause 27: Destination out of order (Cause 27)

This means that the final connection to the far end was malfunctioning. It might be

as simple as the equipment being switched off or there might be a line fault.

Cause 28: Invalid number format (Cause 28)

The number dialed is an invalid format. This is always caused by dialing the wrong

number. Check the number and prefix(es) and try again.

Cause 29: Facility rejected (Cause 29)

This means that the far end cannot accept the ISDN call correctly – maybe the

number dialed is a voice line or a dedicated FAX machine instead of a video

conferencing system.

Cause 30: Response to status inquiry (Cause 30)

This should never occur, as it implies an invalid sequence being sent by V-There to

the local switch. Check carefully that the V-There ISDN settings are correct as

setting up the wrong switch type can cause this.

Cause 31: Unspecified reason for termination (Cause 31)

This indicates a normal call termination but no other message seems appropriate.

This has been seen on some PABX systems when terminating a voice call to a non-

ISDN line.

Resource unavailable causes

These occur when the ISDN network does not supply some required resource. None

of these can be directly resolved by user action.

Cause 34: No circuit/channel available (Cause 34)

This usually means that there are not enough lines to connect the call – often seen in

H0 calls when the last line cannot be dialed. Remedy is to try again later.

Page 63

ClearOne Communications ~ www.clearone.com

Appendix B ~ ISDN Error Codes

Cause 38: Network out of order (Cause 38)

This means that the ISDN network is not functioning and that this is likely to be the

case for some considerable time. After checking the dialed number, consult the local

ISDN service provider.

Cause 41: Temporary failure (Cause 41)

This means that the ISDN network is not functioning correctly but it should not last

for long. Retry the call after a few minutes and it should work.

Cause 42: Switching equipment congestion (Cause 42)

This means that the major ISDN trunk lines are very busy. The distinction between

this and Cause 34 is that Cause 34 is usually generated when the local ISDN switch

is busy whereas Cause 42 is generated when the major trunk lines are busy.

Cause 43: Access information discarded (Cause 43)

This means that the network could not deliver all required information to the far

end. Usually indicates the far end is not on a true ISDN line or it is not properly

configured.

Cause 44: Requested circuit/channel not available (Cause 44)

This indicates that the local ISDN network could not supply what V-There requested.

This indicates either that V-There was not properly configured or there is a problem

in the V-There ISDN interface.

Cause 47: Resources unavailable (Cause 47)

This means something was not available but no other message adequately describes

the problem.

Service or option unavailable causes

These occur when the V-There is requesting an option that the ISDN network cannot

provide. V-There does not make use of any advanced optional features of ISDN.

These errors are usually caused by incorrect configuration of V-There or the ISDN

line. Simply re-trying the call is unlikely to resolve the problem (unlike the previous

the category, where it might).

Cause 49: Quality of service unavailable (Cause 49)

This would occur when the call is being routed through a non-ISDN link, which is

experiencing problems. Try again later.

Cause 50: Requested facility not subscribed (Cause 50)

Cause 57: Bearer capability not authorized (Cause 57)

Cause 58: Bearer capability not presently available (Cause 58)

Page 64

ClearOne Communications ~ www.clearone.com

Appendix B ~ ISDN Error Codes

Cause 63: Service or option not available (Cause 63)

All of these suggest one of two problems. The most likely problem is with the ISDN

service provider (PABX or telephone company), but before calling them, you should

carefully check the switch type in the ISDN Settings screen as well as the restricted

setting on the same screen.

Service or option not implemented causes

These errors occur when V-There is requesting something not implemented on the

ISDN line. This is either incorrect configuration of the V-There or the ISDN line.

Cause 65: Bearer capability not implemented (Cause 65)

Cause 66: Channel type not implemented (Cause 66)

Cause 69: Requested facility not implemented (Cause 69)

Cause 70: Only restricted bearer capability available (Cause 70)

Cause 79: Service or option not implemented (Cause 79)

These cause codes are very similar to the service or option unavailable codes above

except they imply a more permanent problem with the ISDN service provider.

Invalid message causes

These occur due to a problem in low-level communication between V-There and the

ISDN service provider. After checking the V-There settings, power cycle the V-There

and try again.

Cause 81: Invalid call reference value (Cause 81)

Cause 82: Identified channel does not exist (Cause 82)

Cause 83: A suspended call exists but not this identifier (Cause 83)

Cause 84: Call identity in use (Cause 84)

Cause 85: No call suspended (Cause 85)

Cause 86: Call with this identity already been cleared (Cause 86)

Power cycling the V-There

should solve problems

related to Causes 81-86.

✍

Page 65

ClearOne Communications ~ www.clearone.com

Appendix C ~ Reprogramming V-There Via Serial Line

Cause 88: Incompatible destination (Cause 88)

The most likely cause is dialing the wrong number—for instance, trying to place a

video call to a FAX machine. Check numbers carefully.

Cause 91: Invalid transit network selection (Cause 91)

This means that somewhere along the routing an invalid network was selected. If the

final dialed number is correct, this is either a temporary problem resolved by re-

dialing or a local PABX is incorrectly configured.

Cause 95: Invalid Q931 message (Cause 95)

This is either a very temporary condition or the ISDN settings for V-There specify

the wrong switch type.

Protocol error causes

These are a result of either a bug in V-There or of the unsuccessful configuring of the

ISDN switch type. They are listed for completeness.

Cause 96: Mandatory information element missing (Cause 96) Cause 97: Message type non-existent (Cause 97) Cause 98: Message not compatible with call state (Cause 98) Cause 99: Information element non-existent (Cause 99) Cause 100: Invalid information element contents (Cause 100) Cause 101: Message not compatible with call state (Cause 101) Cause 102: Recovery on timer expires (Cause 102) Cause 111: Protocol error (Cause 111)

Other causes

Cause 127: Internetworking (Cause 127)

This means an error occurred somewhere on a network which does not provide error

reporting. Try again or consult your ISDN provider.

This procedure is required in either of the following circumstances:

• A web-based download has failed during the copy to flash, rendering the

V-There inoperable.

• For some reason the V-There cannot access the Internet via the built-in

Ethernet port.

Bonded call (2B, 4B, and 6B) Each ISDN channel consists of two lines. The first

64K of the first line are used for voice transmission and the rest for data

transmission. Each line has a separate ISDN number, which you would normally

have to enter when making a call. Therefore, if you want to make a call using three

ISDN channels, you have to enter six ISDN numbers on the Dial screen. However,

for a bonded call, you would enter only one destination number. The IMUX software

will then work out the numbers of the other ISDN channels from the number dialed.
