This chapter describes how to configure the VTA using the Cisco IP/VC Configuration Utility software.
To start the Cisco IP\VC Configuration software click
Start>Programs>Cisco IPVC Tools>Configuration>Cisco IPVC Configuration Utility on the computer on which the configuration utility is installed. The Select Unit dialog box appears.
The Select Unit dialog box (see Figure 5-1) allows you to select the unit you want to configure. The configuration software detects all Cisco IP/VC units that are installed on the same IP segment as the configuration computer and lists the IP address and model number assigned to each unit in the Unit IP field.
To specify a unit to configure, perform the following steps:
Step 1 Enter the IP address of the unit you want to configure in the Unit IP field.
(a) If the unit's IP address is listed in the list box, click the desired IP address.
(b) If the unit you want to configure is on a different network segment, enter its IP address in the Unit IP field.
Step 2 Click Next.The Enter Password dialog box appears.
Step 3 Enter the password required to log onto the unit. The VTA configuration is protected by a modifiable configuration password. The default password for all VTAs is cisco.
The password has a maximum of 16 characters and is case-sensitive: for example, you must enter VTA in uppercase; and enter cisco in lowercase. We recommend that you change this password and assign a unique password for each VTA during configuration.
Step 4 Click Next.The Configuration Source dialog box appears.
After you specify a unit and enter its password, the Configuration Source dialog box appears (see Figure 5-2). This dialog box provides information about the unit you have selected.
Table 5-1 describes information displayed in the Configuration Source dialog box.
| Parameter | Description |
Unit Type | The model number of the selected unit. |
Hardware Version | The version of the unit's hardware configuration. |
Software Version | Allows you to view the versions of the software installed on the embedded memory. To view the versions, click the button. |
Table 5-2 describes the software version information that appears when you click the Software Version button.
| Software | Description |
Unit Version | The Gateway software version. |
Gatekeeper Version | The version number of the internal Gatekeeper. |
Stack Version | The full version number of the H.323 protocol stack used by the unit. |
MIB Version | The version of the proprietary MIB for SNM. |
The configuration parameters that appear in the Cisco IP/VC Configuration Utility are taken from a file stored on the local computer. During installation a source file containing the default configurations written to the unit's Flash memory is copied to the utility folder. A listing for this file appears in the Source list box as Plug & Play. The first time the unit is configured, the Plug & Play contents are displayed in the Configuration Utility.
You can modify parameters that appear in the unit, save the changes, and upload a file containing the changes to the unit's Flash memory. Save changes under a unique filename. The new file can be used to reprogram the unit's memory and to program other VTA units. The new file appears as a Source option only on the current computer.
A second default listing appears in the Source list. The listing is called Current. Current loads the last source file saved to the unit from the current computer into the Cisco IP/VC Configuration Utility.
To select a source file to view or modify, perform the following steps:
Step 1 Click on the Source text box to display the list of available source files.
Step 2 Select the source file you want to load. Current is the default selection.
Step 3 Click Unit Setup. The source file loads into the utility and the Accepting Nodes box appears. The box displays the IP address of the unit you selected and shows the progress of the file being loaded. The Unit Identification window appears after the file loads.
The Unit Identifications window (see Figure 5-3) displays information regarding the selected VTA. It allows you to specify the location where the VTA is physically placed and to set the time differential for a remote Cisco IP/VC unit located in another time zone.
Table 5-3 describes the Unit Identification parameters.
| Category | Description |
Unit's Name | Product name (read-only). |
Location | Area where the unit is physically placed. |
Contact | The URL (read-only). |
Description | The unit model number (read-only). |
Date/Time | Opens the Date/Time Settings dialog box where you can view and set the time differential when the unit is located in a different time zone. |
Enter a description of the location where the unit resides and click Next. The Network Parameters dialog box appears.
The Network Parameters dialog box lets you set various network parameters (see Figure 5-4).
The network parameters to set are:
Default Gatekeeper IP---the IP address of the gatekeeper where the VTA is registered.
Port---the default port for gatekeeper communication is 1719, which is the H.323 standard. Do not change it unless the default gatekeeper specifies a different one.
Default Router IP---the IP address of the router for the VTA's network segment.
Transcoding Priority---not applicable for the VTA.
Terminal ID---an alias for the VTA. This is an alphanumeric field.
Phone Number---the number other systems must dial to call the VTA (maximum length 12 digits).
The VTA has only one LAN port. This must be connected to the LAN segment and its IP address defined, along with the IP subnet mask. The Description parameter is an optional alphanumeric field that you can use to describe the specific VTA (see Figure 5-5).
The LAN Port Settings dialog box displays the following parameters:
Port Number---displays the number of the port you are configuring. This is a read-only parameter whose value is always 1.
Enabled---This port must always be enabled.
Port Type---displays the type of LAN access method. This is a read-only parameter.
MAC Addr.---displays the hardware Media Access Control address for this LAN port. This is a read-only parameter.
IP Address ---displays the IP address of this LAN port.
IP Mask---allows you to define what portion of the IP address is used for sub-network definitions; see the "Upgrading the VTA Software" appendix.
Description---allows you to type a text description of this LAN port. This is a required field; it is limited to a maximum of 31 characters (the default description is "attached to shared segment").
The Dialing Parameters dialog box lets you enter delimiter and bandwidth information (see Figure 5-6).
The Dialing Parameters dialog box displays the following parameters:
Physical STD---displays the data interface standard, which is V.35.
Dialing STD---displays the dialing standard, which is EIA/TIA-366.
Codec Type---displays the communications standard used by the room system the VTA is connected to; this value is always H.320 and cannot be changed.
Outgoing Default Bandwidth ---displays the default bandwidth of calls made from the room system (via the VTA). You can change this setting when dialing by adding a prefix to the dialing stream; see the "Making Calls with the VTA" chapter.
Incoming Default Bandwidth---displays the default bandwidth of calls received by the room system (via the VTA). Remote VTA's that call into the VTA can force this setting to change by adding a suffix to the dialing stream; see the "Making Calls with the VTA" chapter.
You can save VTA configurations to a configuration file, or to the VTA.
The Save Setup dialog box enables you to save the VTA configuration parameters to a local file. The parameters are saved as an *.ini file to the directory in which the Cisco IP/VC Configuration Utility is installed. The next time you run the configuration utility, you can select this file from the Source drop-down list on the Configuration Source dialog box. Saving configuration parameters to a file may be useful if you plan to configure more than one VTA unit.
The Confirm dialog box allows you to upload the configuration parameters to the VTA. For the configuration changes to take place you have to upload them to the unit.
Click Yes at the Confirm dialog box. The message Updating node parameters is displayed while the system transfers the parameters to the VTA.
If there are any ongoing calls when you try to upload the configuration parameters, a warning is displayed. If you choose to upload the parameters anyway, the VTA disconnects all active calls gracefully (that is, from each endpoint, the call appears to have been disconnected at the other endpoint), and restarts.
The VTA restarts upon the uploading of the new configuration. Wait for the VTA to complete the restart process before you operate it. The unit may take longer to restart than the time allotted in the transferring time bar displayed by the configuration software.
The VTA is now configured. You can configure another VTA starting with the configuration procedure or you can run calls using the VTA, which is explained in the "Making Calls with the VTA" chapter.
