User's Manual 3. Getting Started
Version 6.6 15 MediaPack Series
3 Getting Started
The MediaPack is supplied with application software already resident in its flash memory
(with factory default parameters). The MediaPack is also supplied with a Web interface.
For detailed information on how to fully configure the gateway refer to Device Initialization
& Configuration Files and the Web interface chapter below.
3.1 Assigning the MediaPack IP Address
To assign an IP address to the MediaPack use one of the following methods:

HTTP using a Web browser (see 'Assigning an IP Address Using HTTP' on page 16).

BootP (see 'Assigning an IP Address Using BootP' on page 17).

DHCP (see 'Using BootP/DHCP' on page 21).

Serial communication software (e.g., HyperTerminalTM) connected to the MediaPack
via the RS-232 port.
You can use the Reset button to restore the MediaPack networking parameters to their
factory default values (refer to Restoring Networking Parameters to their Initial State on
page 18).
The default device IP Addresses are shown below.
MediaPack Default IP Parameters
FXS/FXO Interfaces Default IP Address
FXS 10.1.10.10
FXO 10.1.10.11
FXS & FXO 10.1.10.10
Default Subnet Mask 255.255.0.0
Default Gateway IP Address 0.0.0.0

User's Manual 16 Document #: LTRT-71405
MediaPack Series
3.2 Assigning an IP Address Using HTTP
To assign an IP address using HTTP:
1. Connect your PC to the device. Either connect the network interface on your PC to a
port on a network hub / switch (using an RJ-45 Ethernet cable), or use an Ethernet
cross-over cable to directly connect the network interface on your PC to the RJ-45
jack on the device.
2. Change your PC’s IP address and subnet mask to correspond with the device factory
default IP address and subnet mask, shown in the table above. For details on
changing the IP address and subnet mask of your PC, refer to Windows™ Online Help
(Start>Help and Support).
3. Access the Web interface (refer to the Web interface chapter in the Product Reference
Manual).
4. Click Reset and click OK in the prompt. The device applies the changes and restarts.
This takes approximately 1 minute to complete. When the device has finished
restarting, the Ready and LAN LEDs on the front view are lit green.
Tip: Record and retain the IP address and subnet mask you assign the device.
Do the same when defining a new username or password. If the Web interface is
unavailable (for example, if you’ve lost your username and password),
use a
BootP/TFTP configuration utility to access the device, “reflash” the load and reset the
password.
5. Disconnect your PC from the device or from the hub / switch (depending on the
connection method you used in step 1 above).
6. Reconnect the device and your PC (if necessary) to the LAN.
7. Restore your PC’s IP address & subnet mask to what they originally were. If
necessary, restart your PC and re-access the device via the Web interface with its
new assigned IP address.

User's Manual 3. Getting Started
Version 6.6 17 MediaPack Series
3.3 Assigning an IP Address Using BootP
Notes:
•The BootP procedure should be performed using any standard
compatible BootP server.
•For Mediant 3000 HA, in order to get the BootP reset request from the
blade, perform a double reset on the system, as described in Private IP
Address and System (Global) IP Address.
Tip: You can also use BootP to load the auxiliary files to the device (refer to
'Using BootP/DHCP' on page 29).
To assign an IP address using BootP:
1. Obtain and install a BootP server application on your PC.
2. Add the client configuration for the device.
3. Reset the gateway physically causing it to use BootP. The device changes its network
parameters to the values provided by BootP.

User's Manual 18 Document #: LTRT-71405
MediaPack Series
3.4 Restoring Networking Parameters to their Default
Values
You can use the Reset button to restore the MediaPack networking parameters to their
factory default values (described in Default Device IP Addresses) and to reset the
username and password.
Note that this process also restores the MediaPack parameters to their factory settings,
therefore you must load your previously backed-up ini file, or the default ini file (received
with the software kit) to set them to their correct values.
To restore parameters to their initial state, take these 6 steps:
1. Back up the ini file. Refer to Backup Copies of ini and Auxiliary Files on page 35.
2. Disconnect the MediaPack from the power and network cables.
3. Reconnect the power cable; the gateway is powered up. After approximately 45
seconds, the Ready LED turns to green and the Control LED blinks for about 3
seconds.
4. While the Control LED is blinking, use a paper clip to press shortly on the reset button
(located next to the AudioCodes logo on the front view). The gateway resets a second
time and is restored with factory default parameters (username: Admin, password:
Admin - both case-sensitive).
5. Reconnect the network cable.
6. Load your previously backed-up ini file, or the default ini file (received with the
software kit). To load the ini file via the Web interface, refer to 'Software Upgrade
Wizard'.

User's Manual 4. Device Initialization & Configuration Files
Version 6.6 19 MediaPack Series
4 Device Initialization & Configuration Files
This section describes the Initialization Procedures and Configuration Options for the
device. It includes:

Startup Process (see below)

Configuration Parameters and Files (refer to Configuration Parameters and Files on
page 25)

BootP/DHCP (see Using BootP/DHCP on page 21)
4.1 Boot Firmware & Operational Firmware
The MediaPack runs two distinct software programs: Boot firmware and operational
firmware.

Boot firmware - Boot firmware (also known as flash software) resides in the
MediaPack's non-volatile memory. When the MediaPack is reset, Boot software is
initialized and the operational software is loaded into the SDRAM from a TFTP server
or integral non-volatile memory. Boot software is also responsible for obtaining the
MediaPack's IP parameters and ini file name (used to obtain the MediaPack's
configuration parameters) via integral BootP or DHCP clients. The Boot firmware
version can be viewed on the Embedded Web Server’s GUI ('Embedded Web Server'
on page 43). The last step the Boot firmware performs is to jump to invoke in the
operational software.

cmp Operational firmware file - The device is supplied with a cmp file pre-installed on
its flash memory. Therefore, this file is not included on the supplied CD. However, if
you are an AudioCodes registered customer, you can obtain the latest cmp version
files (as well as documentation and other software listed in the table above) from
AudioCodes Web site at www.audiocodes.com/support (customer registration is
performed online at this Web site). If you are not a direct customer of AudioCodes,
please contact the AudioCodes' Distributor and Reseller from whom this product was
purchased.
Note: The ini, MIB and Utility files are shipped with the device in CD format
4.2 MediaPack Startup
The MediaPack's startup process begins when the MediaPack is reset. The startup
process ends when the operational firmware is running. The startup process includes how
the MediaPack obtains its IP parameters, firmware and configuration files.
The MediaPack is reset when one of the following scenarios occurs:
1. The MediaPack is manually reset.
2. acOpenRemoteBoard() is called with RemoteOpenBoardOperationMode set to Full
Configuration Mode (valid for VoPLib API users only).
3. There is a device irregularity.
4. Users perform a reset in the Embedded Web Server GUI or SNMP manager.
5. The flowchart in the figure below illustrates the process that occurs in these scenarios.
