Installing Your MVP120 Software
These following installation procedures do not cover every
screen or option; it is assumed that a technical person with a
thorough knowledge of Windows and the software loading
process is doing the installation. Additional information on the
MVP120 software is provided in the online Help.
Note: The phonebook directory configuration process is
different depending on whether or not you have an enabled
H.323 Gatekeeper resident in your network. The “Configuring
Your MultiVOIP” section explains these differences.
The MVP120 software and User Guide are contained on the
MVP120 Installation CD.  When you have finished configuring
your MVP120, you can view and print the User Guide by
clicking the Install Manuals icon.
CAUTION: If you are installing the MVP120 behind a firewall,
the Firewall must support H.323. Refer to your Firewall user
documentation to enable H.323 support.
1. Make certain that your MVP120 has been properly cabled
and that its power is turned on.
2. Insert the MVP120 Installation CD into a CD-ROM drive.
The CD is auto-detectable, so it starts automatically.  It
may take 10 to 20 seconds for the Multi-Tech Installation
CD window to appear.

Configuring Your MultiVOIP
The following steps provide instructions for configuring your
MVP120. The configuration sequence includes IP Protocol
default setup, Channel setup, and Phone Directory Database
setup. The Phone Directory Database setup is configured
differently depending on whether or not the Gatekeeper
function is available and enabled on the Phone Directory
Database dialog box.
1. The IP Protocol Default Setup dialog box displays.
The default Frame Type is TYPE_II. If this does not match
your IP network, change the Frame Type by selecting
SNAP from the Frame Type list. The available Frame
Type choices are TYPE_II and SNAP.
2. In the Ethernet group, enter the IP Address, Subnet
Mask, and Gateway Address unique to your IP LAN.  The
IP address is the unique LAN IP address assigned to the
MVP120.  The Gateway address is the IP address of the
device connecting your MVP120 to the Internet.  Click OK
when you are finished.
3. The Channel Setup dialog box displays. The four tabs in
this dialog box define the channel interface, voice/fax
parameters, billing/miscellaneous parameters, and
regional telephone parameters. 
						

							17 Configuring the MultiVOIP
Check with your in-house phone personnel to verify
whether your local PBX dial signaling is Pulse or DTMF
(tone).  Select the Regeneration option accordingly.
The Inter Digit Time option defines the maximum amount
of time between dialed digits that the unit will wait before
mapping the dialed digits to an entry in the Phone
Directory Database. If too much time elapses between
digits, the wrong number will be mapped and you will hear
a rapid busy signal. If this happens, hang up and dial
again. The default setting is 2 seconds.
In the Flash Hook Timer box, enter the amount of time for
the duration of the flash hook signals output on the FXO
interface. The default setting is 600 milliseconds.
The Message Waiting Light check box must be selected
on the originating and answering voice channel.  This
enables the number dialed to connect you to the
appropriate voice channel, then output that number on the
voice channel. 
						

							MultiVOIP Quick Start Guide
184. The Ring Count FXO box enables you to set the number
of rings received on the FXO interface before answering
the call. The default setting is 2 rings.
Note: Zero (0) means no incoming calls will be answered.
For FXO-to-FXO communications, you can enable a
specific kind of FXO disconnect: Current Loss, Tone
Detection, or Silence Detection. Check with your in-
house phone personnel to verify the type of disconnect to
use. If Current Loss is checked, the VOIP will hangup
when it detects a loss of current on the FXO (phone) port.
For tone detection, select from the lists one or two tones
that will cause the line to disconnect. The person hanging
up the call must then press the key or keys that produce
those tones to hangup a call. For silence detection, select
One Way or Two Way, then set the timer for the number
of seconds of silence before disconnect. The default value
of 15 seconds may be shorter than desired for your
application.
5. The Voice/Fax tab displays the parameters for the voice
gain, DTMF (Dual Tone Multi-Frequency) gain, voice
coder, faxing, and advanced features such as Silence
Compression, Echo Cancellation, and Forward Error
Correction. 
						

							19 Configuring the MultiVOIP
6. You can set up the input and output voice gain so that the
volume can be increased or decreased. Input gain
modifies the level of the audio coming into the voice
channel before it is sent over the Internet to the remote
MultiVOIP.  Output gain modifies the level of the audio
being output to the device attached to the voice channel.
Make your selections from the Input and Output drop-
down lists in the Voice Gain group. The valid range is
+31dB to –31dB with a recommended/default value of 0.
You can also set up the DTMF gain (or output level in
decibels - dB) for the higher and lower frequency groups
of the DTMF tone pair. Make your selections in the drop-
down lists in the DTMF Gain group. When DTMF Out of
Band is checked, the unit reproduces the DTMF tones
instead of passing them through.
Note: Only change the DTMF gain under the direction of
Multi-Tech Technical Support supervision.
7. To change the voice coder, select the Manual option in the
Coder group. Select the appropriate coder from the
Selected Coder list.
If you changed the voice coder, ensure that the same
voice coder is used on the voice/fax channel you are
calling; otherwise, you will always get a busy signal.
Note: If Automatic Coder is selected, enter the bandwidth
in the Max Bandwidth box. Check with your Network
Administrator to determine how much bandwidth is
available.
8. The Fax group enables you to send/receive faxes on the
voice/fax channel. You can set the maximum baud rate for
faxes, the fax volume, and change the jitter value in
milliseconds. 
						

							MultiVOIP Quick Start Guide
20When receiving fax packets from a remote MultiVOIP, it is
possible for individual packets to be delayed or received
out of order due to traffic conditions on the network. To
compensate for this effect, the MVP120 uses a Jitter
Buffer. The Jitter Value box allows the MVP120 to wait a
user-definable period of time, in milliseconds, for delayed
or out of order fax packets. The range of allowable Jitter
Values is 0 to 400 with a default of 400 milliseconds.
If you do not plan to send or receive faxes on the voice/fax
channel, you can disable faxes in the Fax group.
9. You can enable the voice/fax advanced features by
clicking (checking) the silence compression, echo
cancellation, or forward error correction options.
The Silence Compression option defines whether silence
compression is enabled for the voice channel. If silence
compression is enabled, the MVP120 will not transmit
voice packets when silence is detected, thereby reducing
the amount of network bandwidth used by the voice
channel.
The Echo Cancellation option defines whether echo
cancellation is enabled for the voice channel. If echo
cancellation is enabled, the MVP120 will remove echo
which improves the quality of sound.
The Forward Error Correction (FEC) option defines
whether forward error correction is selected for the voice
channel. The FEC feature allows some of the voice
packets that were corrupted or lost to be recovered. FEC
adds an additional 50% overhead to the total network
bandwidth consumed by the voice channel.
10. The Billing/Misc tab displays the parameters for auto call,
automatic disconnection, billing options, and dynamic jitter
buffer.
