disconnected. Jitter is the inter-arrival packet deviation
(phase shift of digital pulses) over the transmission
medium that causes voice breakup which can be
particularly disruptive to voice communications. The
default setting is 20 milliseconds. A higher value means
that the voice transmission will be more accepting of jitter.
A lower value will be less tolerant of jitter.
Consecutive Packets Lost defines the number of
consecutive packets that are lost after which the call is
automatically disconnected. The default setting is 30
packets.
Call Duration defines the maximum length of time (in
seconds) that a call remains connected before the call is
automatically disconnected. The default setting is 180
seconds.  A call limit of three minutes may be too short for
most configurations. Therefore, you may want to increase
this default value.
14. You can set billing options for inbound and/or outbound
calls by checking them in the Billing Options group and
then entering the charge in cents per number of seconds.
15. A minimum and maximum set of values can be set for
Dynamic Jitter Buffer. When receiving voice packets
from a remote MultiVOIP, it is possible to experience
varying delays between packets due to traffic conditions
on the network. This is called Jitter. To compensate for this
effect, the MVP110 uses a Dynamic Jitter Buffer. The Jitter
Buffer allows the MVP110 to wait for delayed voice
packets by automatically adjusting the length of the Jitter
Buffer between configurable minimum and maximum
values. An Optimization Factor adjustment controls how
quickly the length of the Jitter Buffer is increased when
jitter increases on the network. The length of the jitter
buffer directly effects the voice delay between MVP110
gateways.

42The Minimum Jitter Value default setting is 150
milliseconds, the Maximum Jitter Value default setting is
300 milliseconds, and the Optimization Factor default
setting is 7.
If your country/region is not the default USA, click the
Regional tab and proceed to step 17.
16. To change the Tone Pairs on the Regional tab, click the
Country/Region down arrow and highlight your specific
country or region.
Note: If your country or region is not listed, click Custom
to define it.
The Tone Pairs group enables you to select/modify the
parameters.  Click OK when finished.
17. From the Main menu, click Phone Book to display the
Phone Directory Database dialog box. Make certain the   
						

							43 Configuring MultiVOIP Slaves
Proprietary Phonebook option is enabled and in the
Database Type group, select the Slave option. The
Master IP Address box becomes active.
Note: After you have enabled the Slave option, the Slave
Status button is replaced by the Update button. Once
your Phone Directory database has been created, you can
click this button to refresh the entries in the Phone
Directory Database window.
18. Enter the IP address (204.022.122.118) of the New York
Office MVP110 in the Master IP Address box and enable
the Send Status Report to Master so that status reports
are sent to the Master MVP110.
Note:  In a Dial-On-Demand (DOD) network, you should
leave Send Status Report to Master  disabled. This
allows the router to disconnect whenever there is no voice
activity. Note that Slaves with Send Status Report to
Master disabled will show up as “Unknown” when viewing
Slave status on the Master.
19. Click OK to return to the Main menu.

4420. Click Download Setup to write the new configuration to
the slave unit. The Save Setup dialog box displays.
21. Select  the Save Current Setup as User Default
Configuration check box and click OK. The setup
configuration is written to the MVP110.  After the setup is
written to the MVP110, it reboots.
22. Check that the Boot LED on the MVP110 is off after the
download is complete. This may take several minutes as
the MVP110 reboots.
23. You are returned to the Main menu.
Your MVP110 is operational at this time.
Repeat the process for each of the slave units. When all
slaves have been configured, go to “Deploying the VOIP
Network.”   
						

							45 Configuring MultiVOIP Slaves
Deploying the VOIP Network
For a Proprietary Phone Directory database, the VOIP
administrator can deploy the pre-configured slave MVP110s to
their remote sites. The remote site administrators need only
connect power to the pre-configured MVP110, connect the
MVP110 to their Ethernet LAN and predefined telephone
equipment, and then wait for the phone directory database to
be downloaded.
With the Gatekeeper option enabled on the Phone Directory
Database dialog box, all MVP 110s are configured as
“Gatekeeper” and cannot be downloaded. In this case, each
MVP 110 Phone Book will be programmed with phone
numbers for its own channel. These phone numbers are
registered with the H.323 Gatekeeper (See the “Registering
with a Gatekeeper Phone Directory” section discussed earlier.)
Remote Site Administrator
The following steps are for MVP 110 H.323 endpoints. For
non-MVP 110 H.323 endpoints, refer to the appropriate
installation documentation.
1. Unpack your MVP 110.
2. Connect one end of the power supply to a live AC outlet
and connect the other end to the Power connection on
your MVP 110 (See Figure 5).

3. Connect a network cable to the ETHERNET (RJ-45)
connector on the back of your MVP110.
4. If you are connecting a station device such as an analog
telephone, fax machine, or Key Telephone System (KTS)
to your MVP110, connect a phone cable from the phone
connector on the MVP110 to the Phone connector on the
back of the MVP 110 and connect the other end to the
station device.
5. Turn on power to the MVP110 by placing the ON/OFF
switch on the right side panel to the ON position. Wait for
the BOOT LED on the MVP110 to go off before
proceeding. This may take a couple of minutes.
6. At this time your VOIP network should be fully operational.
Dial one of the sites in your network.
