The following cables will be locally sourced:
• Cables between DEX28-VR3P and PBX or DTS
Unpacking
Check that the equipment has not been damaged during transport. Damaged equipment that needs to be replaced or repaired at a service shop must be reported immediately and sent back.
Connect a Terminal or PC to the Console Port
The console port is a service port to which you can connect a terminal or PC in order to configure the software by using the command line interface. To connect a terminal or PC to the console port, follow the steps:
1. Connect the RJ-45 patch cable to the gateway’s console port and RJ45-DB9 adapter. 2. Connect the DB-9 connector to at terminal or PC.
Connect LAN to the Ethernet Port
To connect DEX28 to local area network, follow the steps:
1. Connect one end of the RJ-45 patch cable to the gateway’s Ethernet port.
2. Connect the other end of the RJ-45 patch cable to Ethernet hub/switch directly. Connection can be also made indirectly through patch panel or wall outlet.
Connect the Power and Turn-On the Device
Caution:Be sure to use the power supply that was supplied with your DEX28 gateway. To connect the AC adapter to the DEX28 gateway and turn it on, follow the steps:
1. Connect one end of the power supply cable to the gateway’s input jack. 2. Connect the other end of the power supply cable to the desktop power adapter. 3. Plug the power cord of the desktop power adapter into an electrical outlet.
The blue LED on the front panel of the gateway lights when you connect the gateway to a power source. The gateway is now ready to be used. If the blue LED does not turn on, refer to the “Troubleshooting the gateway” chapter.

System Configuration Using Console Port
Start HyperTerminal (Start->Programs->Accessories->Communications->HyperTerminal). RS232 settings should be 38400,8,n,1 with hardware flow control (RTS/CTS).
HyperTerminal should start and after pressing enter, following welcome screen from DEX28-VR3P should appear:
Connect PBX to DEX28-VR3P
Connect PBX only to ODD numbered ports (i.e. 1, 3 or 5).
Note:
Instead of RJ45-RJ11 or RJ45-RJ45, RJ11-RJ11 Flat Patch Cable can be used.
Connect DTS to DEX28-VR3P
Connect DTS only to EVEN numbered ports (i.e. 2, 4 or 6).
Connect OWS to DEX28-VR3P
Connect OWS only to EVEN numbered ports (i.e. 2, 4 or 6).

System Configuration Using Web Browser
You can use web browser to configure the gateway. The configuration software runs on Netscape 4.0+, and on Internet Explorer version 5.5 or later.
To configure the gateway, open the web browser and type in IP address of the gateway in address field. Following DEX28-VR3P welcome screen should appear:
Select “Configuredevice…” option, and type in username and password, then click OK.
If you have not set a System password before, the device will accept the default password “admin” and username “system”. Remember that all passwords and usernames are case sensitive.
If you have changed the System password but cannot remember it, then you should configure device over serial (RS232) cable connected to CONSOLE port. Configuration over serial port allows resetting System password to default value system/admin.
(1) Enter IP address of the DEX28 t
Accessing Voice Files on the Network
Voice files are stored on the DEX28-VR3P CompactFlash media, which is accessible as Windows network share. Default name of the share is \\vrserno\Voice,
where vrserno is serial number of the VR3P device.
Consider example where VR3P serial number is VR0001; files on the windows network could be found under the folder \\VR0001\Voice:
Configuring Windows Host Name
To configure Windows Workgroup/Domain where VR3P belongs to, and its NetBIOS name, on the web admin open Configuration / Network Settings page. Workgroup/Domain is configured as “Identity / Workgroup” parameter, and NetBIOS name is configured as “Identity / NetBIOS name” parameter.
In the following example, VR3P is configured to appear as “VR0001” under the “CORPNET” windows domain, in which case voice files could be found on the windows share \\VR0001\Voice.
Voice Recording Parameters
Voice recording quality and other parameters can be configured on the web admin page “Configuration / Ports” Parameter Description:
Directory Number The symbolical name of the extension/port, which is used to identify port. It should be unique across the VR3P device.
The simplest way is to use extension number on the PBX as the value. Default values are 101, 102 etc.
CODEC Compression algorithm used to store voice files. Available CODECs are:
• G.711 – 64 kbps
• G.726 – 16..48 kbps
• MP3 – 8 or 16 kbps
Chosen CODEC influences VR3P capacity to store voice recording. Example: If you select MP3 16 kbps CODEC, then on the VR3P having 2GB CompactFlash, available size for all voice files will be:
(2 GBy – 0.3 MBy sys. space) / 2 kBy/sec = 850 000 sec which is approximately 10 days of continuous recorded voice.
FTP URL The list of URLs where voice files are automatically copied after recording.
Format: ftp://username:password@server/folder
Example: ftp://voice:[email protected]/VR0001
Max Recorded File Size Voice files are kept bellow this limit. Parameter is given in seconds. If the conversation is longer than this parameter, then it is split in multiple voice files, each having up to maximum allowed file size.
Min Recorded File Size Recorded voice files are removed from the system if bellow this limit. Parameter is given in milliseconds.
Voice Activity Detection Enable Enables VAD principle of determining presence of speech, instead of normal monitored messages and orders issued by PBX to DTS.
Note: This parameter should be turned on if MD110/MX-ONE OWS
or the Operator are connected through the port, because OWS and Operator are always in speech from the MD110/MX-ONE point of view.
VAD Threshold Level PCM threshold level to start recording. Higher values decrease sensitivity.
Example: Typical OWS configuration. PBX DN 720
Must be enabled for OWS or Operator!
