6.2 Hardware and software prerequisites

In each of the three configurations, the hardware and software prerequisites are important, since they may vary slightly. 
Each configuration is listed below with both the Voice Server requirements for the server and the client. You must ensure these are met before installing Voice Server. 6.2.1 

Prerequisite hardware/software for stand-alone configuration 
Each computer needs to have at least the minimum hardware and software prerequisites stated in the following sections. 

Hardware 
In the stand-alone configuration, all Voice Server components are installed on one machine. Ensure there are adequate hardware resources, namely CPU speed and memory, that can cope with the demand from Voice Server. 

The minimum requirements are:

Dialogic environment 
Voice Server requires certain prerequisite software and hardware before installation. 

We proceeded in the following order: 
1. Install Dialogic software. 
2. Shut down the computer and install the Dialogic card. 
3. Configure the card. 
4. Test the card. This enables the telephony hardware to integrate with the Voice Server. 

There are two applications: Dialogic System Release 5.x.x for Windows 2000 and GlobalCall Protocol Package 1.00 for Windows 2000. 

These are available either from a CD supplied with the card or by downloading from the following Web site: 
http://developer.intel.com/design/telecom/support/ 

There are several versions of the Dialogic software. Tested versions were 5.0.1, 5.1 and 5.1 with Service Pack 1, 5.1.1 and 5.1.1 with Service Pack 1(for Japanese, Release 5.1 is required as a minimum).

6.3.4 Dialogic card installation 
Voice Server for the Dialogic environment requires a Dialogic board to interface with the telephony environment. 

The boards supported for Voice Server are:
D/120JCT-LS (a 12-port analog board) 
D/240JCT-T1 (a 24-port digital board) 
D/480JCT-1T1 (a dual-span 24-port digital board) 
D/480JCT-2T1 (a dual-span 48-port digital board) 
D/600JCT-1E1 (a dual-span 30-port digital board) 
D/600JCT-2E1 (a dual-span 60-port digital board) 

Dialogic has released another card called the D/41JCT-LS. It is a 4-port analog board. Although it is not included in the officially supported card list, we successfully tested it with Voice Server. 

This is a step-by-step procedure to install the Dialogic board into your Intel machine. This procedure is for a D/120JCT-LS, the card we used in our scenario. 

Step 1: Installing hardware Power off the machine and unplug the power supply. Install the Dialogic card into a free PCI slot, 
preferably in the lowest numbered slot. Figure 6-28 on page 247 shows an installed D/120JCT-LS Dialogic card.

Step 2: Hardware detection Power on the machine and log in as the administrator. The Hardware wizard should appear indicating new hardware has been found, as shown in Figure 6-29 on page 248. Click Next.

Move through the hardware detection windows until you reach the device driver window, 
as illustrated in Figure 6-30 on page 249. 
Windows 2000 will try to determine what drivers match the card. Click Next.

The Dialogic software provides a set of drivers. We select the option Specify a location, as shown in Figure 6-31. Click Next. We need to manually point to the driver, so click Browse, as shown in Figure 6-32. The drivers are located in the DRVR subdirectory of the installed Dialogic software. In our case this is the default folder. Highlight this folder and click Open, as in Figure 6-33. You are presented with a set of drivers. For the D/120JCT card, select the dlgcsram_nt4.inf file, then click the Open button, as shown in Figure 6-34 on page 251.

A confirmation window will appear, as in Figure 6-35. Click OK if correct. The Hardware wizard will indicate the driver it found (Figure 6-36 on page 252). Click Next. The Hardware wizard will present a completed window that looks like Figure 6-37 on page 253. Click Finish.

6.3.5 Dialogic card configuration
Before installing Voice Server, the Dialogic card needs to be configured. These settings can be broken down into two sections, global settings and specific country settings. 

To configure the Dialogic card, use the Dialogic Configuration Manager (DCM) in the Dialogic application folder. First the application must connect to the machine specified by the host name given to the machine. This is shown in Figure 6-38.

The DCM window will show you the installed Dialogic card and the Time-Division-Multiplex (TDM) Bus. Figure 6-39 shows the DCM window. Right-click the installed card. In this case it is a D/120JCT-LS. Select Configure Device, as illustrated in Figure 6-40 on page 255.

The properties window for the selected card is displayed. Changes are required on two tabs, Misc and Country. Set the parameter values for the D/120JCT-LS board as shown in Table 6-1.

Table 6-1 DCM settings table 

Click Apply to save the settings. Then select the Country tab and ensure you have your country selected. Click OK, as in Figure 6-42 on page 257. 

Now right-click the Bus-0 under the TDM Bus and select Configure Device, as illustrated in Figure 6-43 on page 258

The Bus configuration window will appear. One parameter needs to be changed here, as shown in Table 6-2. 

Table 6-2 TDM Bus parameter 

Click OK when done, as shown in Figure 6-44 on page 259. 

Start the card to test the configuration by clicking the green circle, as in Figure 6-45 on page 260. Once completed, the card will be active. The card has a green circle on it to indicate this.
