After you have assigned the Cisco IP/VC 3525 Video Gateway an IP address and connected it to the network, you can configure the Video Gateway for operation. This chapter describes how to configure the gateway for operation. The topics covered include:
After you configure the Video Gateway, you must register the Video Gateway's services with a gatekeeper. The "Registering with the MCM Gatekeeper" appendix describes how to register the Video Gateway and its services with a Cisco MCM Gatekeeper. The "Configuring the Embedded Gatekeeper" appendix describes how to enable and configure the embedded gatekeeper.
The Cisco IP/VC 3525 Video Gateway provides services that allow H.323 LAN endpoints to conference with H.320 WAN terminals using PRI connections. The Cisco IP\VC Configuration Utility lets you:
Before you configure the Video Gateway, we recommend that you review your conferencing strategy. Consider the types of calls your users will make, the types of services you want the Video Gateway to provide, and the bandwidths those services will use.
Each conference service that is created requires a dialing prefix. Create a dialing plan. You can set aside blocks of numbers to assign to similar services. You can use the same prefix when a service is duplicated on other service providers.
To start the Cisco IP\VC Configuration Utility and to select the Video Gateway you want to configure, perform the following steps:
Step 1 Click Start>Programs>Cisco IPVC Tools>Configurarion>Cisco IPVC Configuration Utility. The Select Unit dialog box appears (see Figure 4-1).
Step 2 To select a Video Gateway to configure:
(a) If the Video Gateway is on the same network segment as the configuration computer, the Video Gateway's IP address will appear in the Unit IP list box. Click the IP address.
(b) If the Video Gateway and the configuration computer are on different network segments, you can enter the Video Gateway's IP address in the Unit IP text box.
 | Caution The Cisco IP/VC Configuration Utility can assign the IP address you type into the Unit ID text box to any Cisco IP/VC device residing on the network segment that does not have an IP address associated with the segment. |
(c) Click Next. The Enter Password dialog box appears.
Step 3 Enter the Video Gateway's password and click Next. The default password is cisco. The Configuration Source dialog box appears (see Figure 4-2).
This section describes how to set the Video Gateway's operating parameters in the configuration utility.
The Configuration Source dialog box:
This section provides a brief description of the Video Gateway information and describes how to invoke the Video Gateway configuration module. See

The configuration parameters that appear in the Cisco IP/VC Configuration Utility can be taken from the Video Gateway or from a file stored on the computer running the configuration utility. You must choose a source file you want to load into the configuration utility.
The Source section in the Configuration Source dialog box lets you choose a source file to load. The first time you configure a Video Gateway on the configuration computer, there are two sources listed in the Source list box: Current and Plug & Play.
Current loads the parameters that are actually set on the Video Gateway into the configuration utility. Plug & Play loads parameters stored in a file and copied to the hard disk during installation. The Plug & Play parameters are the default parameters the
Video Gateway is shipped with. It can be used to restore the original configuration.
You can modify the parameters shown in the configuration utility and upload the changes to the Video Gateway. The utility forces you to save the changes as a file in the utility's folder before it up loads the changes. Save file under a unique filename. The file is added to the utility's Source list box and can be used to configure other Cisco IP/VC 3525 Video Gateways. The new file will appear as a Source option only on the current computer.
To select a Video Gateway source file to view or modify, perform the following steps:
Step 1 Click 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 populates the configuration utility and the Accepting Nodes box appears. The box displays the IP address of the
Video Gateway you have selected and shows the progress of the file being loaded. The Unit Identification dialog box appears after the file loads.
The Unit Identification dialog box displays information regarding the selected Cisco IP/VC 3525 Video Gateway. The dialog box allows you to specify the location where the Video Gateway is physically placed and to set the time differential for Cisco IP/VC 3525 Video Gateway if it is located in another time zone.
Table 4-3 shows the Unit Identification dialog box's read-only parameters.
| Category | Description |
|---|---|
Unit's Name | Cisco product name. |
Location | Area where the Video Gateway is physically placed. |

Opens the Date/Time Settings dialog box where you can view and set the time differential when the Video Gateway is located in a different time zone. |
Enter a description of the location where the Video Gateway resides and click Next. The Miscellaneous Parameters dialog box appears (see Figure 4-3).
The Miscellaneous Parameters dialog box allows you to set several important parameters for Video Gateway operation.
To set the parameters in the Miscellaneous Parameters dialog box, perform the following steps:
Step 1 In the Default Gatekeeper IP text box, enter the IP address of the gatekeeper you want the Cisco IP/VC 3525 Video Gateway to use. If you are using the embedded gatekeeper, the IP address is the same as the Video Gateway's IP address. You must have a gatekeeper IP entry.
Step 2 In the Port text box, enter the port number the gatekeeper you want the
Cisco IP/VC 3525 Video Gateway to use uses for communication. The default value is 1719, which is used by many gatekeepers including the embedded gatekeeper.
Step 3 In the Default Router IP text box, enter the IP address of the router the
Cisco IP/VC 3525 Video Gateway will use to communicate to endpoints in other network segments.
Step 4 In the Transcoding Priority text box, set the audio transcoding method you want to take priority. You can also disable this feature.
Step 5 If you want to use the native interactive voice response (IVR) feature, check the Internal IVR Service box. IVR is an automated answering service that handles nondirect dial calls. The service routes incoming call to the destination the caller specifies. The caller uses the keyboard or keypad to respond to IVR.
If you are using another IVR system or if you do not want to use IVR, deselect this feature.
Step 6 In the IVR Operator text box, enter the dialing prefix you want users to use to access the IVR operator. This is the number users will use to place calls to endpoints on the LAN that cannot be dialed directly. Be sure to enter this prefix when you register an endpoint to handle the IVR Operator function in the gatekeeper.
Step 7 If you are using an external IVR system, enter the IP address assigned to the Video Gateway where the IVR functionality is located in the External IVR IP text box.
Step 8 If you are using an external IVR system, enter the port number the IVR uses in the Port text box. For Cisco IP\VC IVR systems the default port is 1620.
Step 9 In the Second Number Delimiter text box, create a string that shall serve as a delimiter to separate phone numbers in a dialing sequence. You can use the characters asterisk (*), comma (,) and pound (#) to create a string of up to
31 characters. This feature allows users whose dialing interface does not let them enter multiple numbers to include the second number of a 2B call in the dial string.
Step 10 In the TCS4 Number Delimiter Text box, enter a unique string that users making TCS4 calls can use to separate the recipient number from the TCS4 code. You can use the characters asterisk (*), comma (,) and pound (#) to create a string of up to 31 characters. There is no default TCS4 delimiter value.
Step 11 After you have set the parameters, click Next. The Bonding Parameters dialog box appears (see Figure 4-4).

Step 1 To enable bonding, click in the Enable Bonding text box. The feature is enabled when a check appears in the box. Bonding is enabled by default.
Step 2 Click the Max. Call Bandwidth text box and select a value for the maximum amount of bandwidth you want to use for bonded calls.
Step 3 Click Next. The LAN Port Parameters dialog box appears.
The LAN Port Settings dialog box allows you to set the IP address information and to enter a description. Since the Cisco IP/VC 3525 Video Gateway has only one LAN port, the port's IP address is the same as the Video Gateway's IP address that was set when the Video Gateway was configured to install on the network. You can use this dialog box to change the Video Gateway's IP address.
To change the Video Gateway's IP address, perform the following steps:
Step 1 If you want to change the IP address, enter the new IP address in the IP Address text box.
Step 2 If you want to change the IP mask for the Video Gateway, type the new IP mask into the IP Mask test box.
Step 3 You can enter a brief comment of up to 31 letters in the Description text box.
Step 4 Click Next. The LAN Parameters dialog box appears.
The LAN Parameters dialog box lets you review LAN Parameter changes.
Step 5 Click Yes to continue. The Services Definition Table appears (see Figure 4-5).
The Services Definition Table allows you to create up to 50 call services the Video Gateway will perform. Service parameters define the call bandwidth and the dialing prefix users can use to place calls having the parameters defined in the service. You must also register these call services with the gatekeeper. This section describes how to define calling services in the Cisco IP/VC 3525 Video Gateway.
The Cisco IP/VC 3525 Video Gateway is shipped with predefined services. The service configurations are saved on the Video Gateway's programmable memory and may be edited or deleted. The Edit button allows you to edit the selected service. The Delete button deletes the selected service.
