CAUTION: Rack Mount Safety Instructions (UL)
When installing the chassis in a rack, be sure to implement the following safety
instructions recommended by Underwriters Laboratories:

•

Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be
greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.

•

Reduced Air Flow - Installation of the equipment in a rack should be such that
the amount of air flow required for safe operation on the equipment is not
compromised.

•

Mechanical Loading - Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.

•

Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when
addressing this concern.

•

Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (for example, use of power strips).

V7122 Digital Gateway Installation Guide

To attach the device to a 19-inch rack, follow these 2 steps:
1

Position the device in your 19-inch rack and align the left-hand and right-hand bracket
holes to the required holes in the vertical tracks of the 19-inch rack.

Use standard 19-inch rack bolts (not provided) to fasten the device to the frame of the
rack.

3Com recommends using two additional rear mounting brackets (not supplied) to provide
added support.

Users assembling the rear brackets by themselves should note the following:
•

The distance between the screws on each bracket is 26.5 mm.

•

To attach the brackets, use 4-40 screws with a maximal box penetration length
of 3.5 mm.

To place the device on a 19-inch racks shelf, follow these 2 steps:
1

Place the device on the preinstalled shelf.

You are now recommended to take the optional steps of fastening the device to the
frame of the rack (as described above) while it is placed on the shelf, preventing it from
sliding when inserting cables into connectors on the rear panel.

CHAPTER 3: CONFIGURING THE V7122
GATEWAY

The V7122 gateway is supplied with application software already resident in its flash memory
(with factory default parameters).
Section Assigning the V7122 Gateway IP Address describes how to assign IP addresses to
the V7122. Section Configuring the V7122 Basic Control Protocol Parameters describes how
to set up the V7122 gateway with basic parameters using a standard Web browser (such as
Microsoft TM Internet Explorer).
Section Assigning the V7122 Gateway IP Address applies equally to H.323 and
SIP.

Assigning the V7122 Gateway IP Address
The V7122 gateway is composed of one or two identical media gateway modules. These
media gateways are fully independent, each gateway having its own MAC and IP addresses
(Table 6 shows the default IP addresses of the V7122 gateway). To assign an IP address to
each of the V7122 gateway modules use one of the following methods:

HTTP using a Web browser (see Assigning an IP Address Using HTTP).

BootP (see Assigning an IP Address Using BootP).

The embedded Command Line Interface (CLI) accessed using Telnet (see Assigning an
IP Address Using the CLI).

DHCP (see the V7122 Digital Gateway User Guide).

Table 6 lists the default IP addresses of the V7122 gateway. You can use the Reset button
at any time to restore the V7122 gateway networking parameters to their factory default
values (see Restoring Networking Parameters to their Initial State).
Table 6

V7122 Gateway Default Networking Parameters

Double module (up to 16 trunks)

10.1.10.10 (Trunks 1-8) and 10.1.10.11 (Trunks 9-16)

Default subnet mask is 255.255.0.0, default gateway IP address is 0.0.0.0

V7122 Digital Gateway Installation Guide

Assigning an IP Address Using HTTP
To assign an IP address using HTTP, follow these 9 steps:
1

Disconnect the V7122 gateway from the network and reconnect it to your PC using one
of the following two methods:

Use a standard Ethernet cable to connect the network interface on your PC to a port
on a network hub / switch. Use a second standard Ethernet cable to connect the
V7122 gateway to another port on the same network hub / switch.

Use an Ethernet cross-over cable to directly connect the network interface on your
PC to the V7122 gateway.

Change your PCs IP address and subnet mask to correspond with the V7122 gateway
factory default IP address and subnet mask (shown in Table 6). For details on changing
the IP address and subnet mask of your PC, see the Windows™ Online Help
(Start>Help).

Access the V7122 gateway first modules Embedded Web Server (see Accessing the
Embedded Web Server).

In the Quick Setup screen, set the V7122 gateway IP Address, Subnet Mask and Default
Gateway IP Address fields under IP Configuration to correspond with your network IP
settings. If your network does not feature a default gateway, enter a dummy value in the
Default Gateway IP Address field.

Click the Reset button, and then at the prompt click OK; the V7122 gateway applies the
changes and restarts. This takes approximately three minutes to complete. When the
V7122 gateway completes the reset, the Ready and LAN LEDs on the front panel are lit
green.
Record and retain the IP address and subnet mask you assign the V7122
gateway. Do the same when defining new username or password. If the
Embedded Web Server is unavailable (for example, if you have lost your
username and password), use the BootP/TFTP configuration utility to access the
device, “reflash” the load and reset the password (see the V7122 Digital
Gateway User Guide for detailed information on using a BootP/TFTP
configuration utility to access the device).

Repeat Steps 3 to 5 for the V7122 gateway’s second module (if used).

Disconnect your PC from the V7122 gateway or from the hub / switch (depending on the
connection method you used in Step 1).

Reconnect the V7122 gateway and your PC (if necessary) to the network.

Restore your PCs IP address and subnet mask to what they originally were. If necessary,
restart your PC and re-access the V7122 gateway using the Embedded Web Server with
its new assigned IP address.

V7122 Digital Gateway Installation Guide

Assigning an IP Address Using BootP
BootP procedure can also be performed using any standard compatible BootP
server.
You can also use BootP to load the auxiliary files to the V7122 gateway (see the
V7122 Digital Gateway User Guide).
To assign an IP address using BootP, follow these 13 steps:
1

Open the BootP application (supplied with the V7122 gateway software package).

Click on the Edit Clients icon

Click on the Add New Client icon
(Figure 11).

In the Client MAC field, enter the MAC address of the gateway. The MAC address is
printed on a label located on the base of the V7122 gateway.

Verify that the check to the right of the Client MAC field is selected. This enables the
particular client in the BootP tool (if the client is disabled, no replies are sent to BootP
requests).

In the Client Name field, enter a descriptive name for this client so that it is easier to
remember which gateway the record refers to. For example, this name could refer to the
location of the gateway.

In the IP field, enter the IP address you want to assign the gateway. Use the normal
dotted decimal format.

In the Subnet field, enter the subnet mask you want to assign the gateway. Use the
normal dotted decimal format. Ensure that the subnet mask is correct. If the address is
incorrect, the gateway may not function until the entry is corrected and a BootP reset is
applied.

In the Gateway field, enter the IP address for the default gateway. If you do not know the
IP address for the default gateway, contact your network administrator.

ini file) to enable enhanced gateway provisioning. Table 13 presents a brief description of
the ini file and the auxiliary files that are available: CAS, Voice Prompts, and Call Progress
Tones (CPT). For information about additional auxiliary files, see the V7122 Digital Gateway
User Guide.
Table 13

ini and Auxiliary Files Descriptions

File Type

Description

ini

Load this file to provision the V7122 gateway parameters. The Embedded Web Server
enables practically full device provisioning but customers may occasionally require
new feature configuration parameters in which case this file is loaded.
Note that loading the ini file only provisions parameters that are contained in the ini file.
If a parameter is not specified in the ini file, values associated with that parameter are
reset to a default value. These values may not be the same as the values that were
configured for the VoIP gateway at the time of manufacture.
Note: After the file has completed loading, the VoIP gateway automatically restarts
(software is loaded from the flash).

CAS

Up to eight different CAS files containing specific CAS protocol definitions.
These files are provided by 3Com to support various types of CAS signaling.

Voice Prompts

The voice announcement file contains a set of Voice Prompts to be played by the
V7122 gateway during operation on Call Agent request.

Call Progress Tones This is a region-specific, telephone exchange-dependent file that contains the Call
Progress Tones levels and frequencies that the VoIP gateway uses. The default CPT
file is: U.S.A.
Prerecorded Tones The dat PRT file enhances the gateways capabilities of playing a wide range of
telephone exchange tones that cannot be defined in the Call Progress Tones file.
User Information

The User Information file maps PBX extensions to IP numbers. This file can be used to
represent PBX extensions as IP phones in the global IP world.

calls after the Lock Timeout value expires. Note that if no traffic exists and the time has
not yet expired, the gateway locks.

Under the RESET group, select the Yes option from the Burn to FLASH drop-down list,
and then click Reset; the auxiliary files are saved into flash and the V7122 gateway
restarts. This takes approximately three minutes to complete. When the V7122 gateway
has finished restarting, the Ready and LAN LEDs on the front panel are lit green.
