PRI E1 Channel Information
The PRI Status screen for E1 shows 30 channels. However, E1 trunk lines have 32 timeslots, numbered 0 - 31. Timeslot 0 is used for framing, and timeslot 16 is used for call signaling (the D channel). The remaining 30 timeslots are used as bearer (data) channels. In call signaling between Polycom equipment and the switch, these channels are numbered 1-15, 17-31. But the PRI Status screen numbers these channels in the range 1-30. On the PRI Status screen, channels 1-15 control the status of timeslots 1-15, and channels 16-30 control the status of timeslots 17-31.
Dedicated Full PRI T1 or E1 Line
All channels should be active for a full T1 or E1 line dedicated to your ViewStation FX or VS4000.
V.35/RS-449/RS-530 Network Interface Module
The following paragraphs provide technical information about the V.35/RS-449/RS-530 network interface module available with the ViewStation EX, ViewStation FX, and VS4000. The systems V.35/RS-449/RS-530 network interface module is not interchangeable with the previous V.35 network interface module. The new module uses HD-44F connectors for ports 1 and 2, and uses a keyed RJ-45 connector for the serial link to the back panel of the ViewStation FX or VS4000. The cable used with the V.35/RS-449/RS-530 network interface module is the same as is used for the PRI network interface module. It is shown in Figure 2-5. An HD-44M to DB-25F adapter cable is available to connect existing ViewStation DB-25 interface module V.35 network cables. Common speeds are divisible by both 56 and 64. The V.35/RS-449/RS-530 network interface module supports the following common speeds:

and service prefixes and endpoint addresses. Before you design a dial plan, you should document:
Current telephone number dialing patterns Planned router locations Traffic routing requirements
Because no standard protocol defines the dynamic routing of E.164 addresses, H.323 dial plans must be configured statically and managed on gateway and gatekeeper platforms. To reduce the complexity of the configuration, confine H.323 addresses to one portion of the dial plan.
A well-designed dial plan distributes the dial plan logic among the gateways and gatekeepers. Try to keep the dial plan logic at the highest component level for example, allow the gatekeeper to handle routing and fail-over decisions. This allows individual zones to be added or modified without affecting other zones, so the deployment is very scalable.
To assign gateways and gatekeepers: 1. 2. 3. Determine the area that your dial plan covers. Determine what calling area(s) each gateway and gatekeeper will be responsible for. Determine the peak traffic volume, and determine how many gateways will be required to handle anticipated increases in this peak volume. Logically group the gateways into zones to determine how many gatekeepers you need. A zone can have one or many gateways. The number of zones you define depends on the gateways capacity and traffic. Determine which gatekeeper should administer each zone.

System services are defined within PathNavigator. They include many of the functions that simplify the users interaction with the Polycom Office. System services only work within a zone. PathNavigators gateway and MCU services make it simple for the user to dial out through a gateway or dial into a conference. For these services to be effective, the gateway service information such as call speed, service and zone prefixes, and device capabilities must be registered with PathNavigator. Gateway and MCU services are defined in both PathNavigator and the MGC platform itself. It is critical that the prefixes are exactly the same in each system.
Administration, Policies, and Routing
Administration Plan The videoconferencing administration plan allows the system administrator to manage user permissions and network policies. Your plan should define:
Superusers Administrators Permissions for groups and for individuals Policies such as bandwidth allocation per user
Default Group Policy A group policy allows you to define dialing properties, services, and bandwidth management parameters for all members of a defined group without having to configure these individually for each user. The default group is normally all users, and the policy settings for this group are the default group policy. The administrator sets policy, services, and other settings for this and other groups.

Least-Cost Routing Least-cost routing enables calls that originate inside the organization to be routed in the manner that incurs the lowest expense. In order for least-cost routing to be implemented, the network topology must be defined the gateways on each network, WAN link capacities, and other factors. Each gateway has an associated least-cost routing table which is created by the administrator. The table consists of dial string entries (country code, area/city code, etc.) and cost. For calls between networks, the tables are compared to identify the least-cost route for the call. Least-cost routing will not be used if the least-cost route cannot be identified, if the required resources are unavailable, or if bandwidth limitations exist on the WAN link.
If your organization has special rate plans, those should be incorporated into the least-cost routing tables.

Network Topology

You will need the network topology information described in LAN/WAN Considerations on page 52 when you design your dial plan and configure PathNavigator to manage your video network. If the network is physically changed, you will need to update PathNavigators network information so that it can manage the video network effectively. PathNavigator provides the means for you to assign ISDN numbers to endpoints. The way numbers are assigned depends on your network:
E.164 provisioning Choose E.164 provisioning if you are

using private numbers.

ISDN alias assignment If you assign ISDN numbers to
endpoints, then the ISDN ranges need to be provided to the gatekeeper. These numbers must be coordinated with your local ISDN provider as these numbers cannot be self-populated. Assigning numbers that are not in your domain will result in failed calls when users outside the organization try to access users within the organization with self-populated numbers.
Automatically assigned numbers PathNavigator can
automatically assign direct inward dial (DID) numbers or gateway extensions. You cannot automatically assign both types of numbers on the same network.

Neighbor gatekeepers

Neighbor gatekeepers allow for the distribution of the workload across logical boundaries within the organization. This enables more efficient use of the network by limiting communication across WAN links. When a call originates in one gatekeepers zone and that gatekeeper is unable to resolve the dialed address, it will be forwarded to the neighbor gatekeepers for resolution.

The ISDN BRI lines between the PBX or other CPE and the
videoconferencing system(s) should be provisioned in the same way as ISDN BRI lines that would be connected the system(s) directly from a Telco, as described below. The following requirements are common to all BRI deployments.
ISDN BRI lines need to be configured in the same way as one of
the following two Bell Core equivalents: Capability Package R: Circuit Switched Data on 2 B channels. Data capabilities include Calling Number Identification. No voice capabilities are provided. Capability Package S (recommended if system is not behind a PBX): Alternate Voice/Circuit Switched Data on 2 B channels. Data and voice capabilities include Calling Number Identification.
Both B channels must carry circuit-switched videoconferencing
data (voice can be added but is not required).
The ISDN BRI service must allow videoconferencing calls to be
dialed on either B channel or on both simultaneously.
The D channel should not permit X.25 packet data. The ISDN BRI service must be configured as Terminal Type A. The ISDN BRI service must support automatic Terminal
Endpoint Identifiers (TEIs).
The ISDN BRI service must be tariffed and available from the
customers local central office.
DCP (Digital Communication Port) On Lucent Definity ECS

Network Configuration

The Lucent Definity G3 supports DCP connectivity on V2 and later. ViewStation DCP-based systems support the Lucent Definity DCP 2-wire configuration, and requires the DCP ports to be programmed as PDM. No NT1 devices are required with DCP-based systems. Typically, 4-pair Cat-5 cabling is used between the Definity ECS and the network interface module of the ViewStation, terminated on RJ-45 jacks.

Installation

You can install ViewStation systems in the same room as the Quad BRI network interface module, or you can connect to the Quad BRI network interface module through the buildings wiring. You can locate the system up to 250 feet away from the Quad BRI network interface module, with the following provisions:

Table 3-7. Site Considerations

Factor For best results

Access to required connections
Ensure that the equipment will be within 6 feet (1.8 m) of power and network connections. Ensure that cables are routed in a way that does not inconvenience people who use the room. Ensure that the camera will normally point toward an area that is well-lit but not exceptionally bright. Lighting should be diffuse to prevent harsh shadows. If there is a window in the room, ensure that the camera does not normally point toward it. Backlighting makes the speaker appear in silhouette.

Room lighting

Room color and decor
The camera will perform best if the room furnishings are medium to dark in color and do not have polished or reflective surfaces. Ensure that the camera normally points toward an area that is of a medium shade and does not contain detailed, patterned, or brightly-colored elements. For example, a blue or gray wall provides a more effective backdrop than a bright painting. To prevent autofocus problems, place an object somewhere near the center of the cameras default position.

Items in camera range

Ensure that no confidential material can be inadvertently disclosed to callers. For example, ensure that white boards in the conference room are not used for engineering sketches.
Table 3-7. Site Considerations (Continued)
Acoustics and background noise
Ensure that there is no audible echo in the room where the camera and microphone(s) will be installed. Carpeting, drapery, and upholstered furniture all help to reduce echo problems. Non-rectangular rooms have less echo than standard conference rooms. Refer to the documentation for the specific equipment model for information on where to place the microphone(s).

Configuring the System to Operate Behind a Firewall
To make calls through a firewall, you must open the following ports and assign them to the videoconferencing system:
Table 4-1. Firewall Ports to Open for Videoconferencing

Port Used for

389 (TCP) 1503 (TCP) 1718 (UDP) 1719 (UDP) 1720 (TCP) 1731 (TCP) 3230-3235 (TCP/UDP) 3603 (TCP)
ILS registration Microsoft NetMeeting T.120 data sharing Gatekeeper discovery Gatekeeper RAS (must be bidirectional) H.323 call set-up (must be bidirectional) Audio call control (must be bidirectional) Signalling and control for audio, call, video, and data/FECC Web interface
Configuring the System to Operate Behind a NAT
The System is behind a NAT option allows the user make calls outside the internal network. At this time, it is not possible to make videoconferencing calls within the internal network when the System is behind a NAT option is selected. To make videoconferencing calls within the network, users must deselect the System is behind a NAT option before making the call. 1. 2. 3. 4. 5. 6. 7. Determine the NATs external (WAN) IP address. Determine the IP address of the system. This can be found in the System Information screen. Go to Quality of Service and Firewalls screen (System Info > Admin Setup > LAN/H.323 > H.323 > QOS). Select Use Fixed Ports. Select System is behind a NAT. Enter the NATs external IP address into the NAT outside (WAN) address field. Write down the Fixed TCP and UDP port numbers displayed on this screen. The default values are: TCP: 3230 to 3231 UDP: 3230 to 3235 8. 9. Reset the firewalls fixed ports from step 4 to be permanently open, and redirect them to the IP address of your system. To accept incoming calls, open and redirect port 1720 to the IP address of your system.
Connecting the System to a PC
In some situations you may want to connect a laptop directly to the ViewStation EX, ViewStation FX, or VS4000. This allows you to:
Update software on a system that is not connected to a LAN. Use IP-based functions such as PolySnap or Visual Concert PC
with a system that is not connected to a LAN.
Upload Microsoft PowerPoint files to the system if you do not
have a Visual Concert data collaboration unit.
Connect a PC to the LAN through a LAN-connected system if
there is only one LAN connection in the room. This section explains how to set up and connect your PC to a ViewStation EX, ViewStation FX, or VS4000.

PC Requirements

The system requirements for connecting a PC to the system are:
Microsoft Windows 95, 98, 2000, or NT Desktop PC connected to a LAN or laptop with a 10 Mbps or 100

Mbps Ethernet LAN card

Ethernet cable Microsoft Internet Explorer 4.0 or higher (recommended) or

Netscape 4.5 or higher

Connecting the PC to the LAN Through the ViewStation EX, ViewStation FX, or VS4000
Do this if you need to use the system to provide LAN connectivity for your PC. 1. 2. 3. 4. 5. Ensure that the PC and the system are both powered off. Connect the system to the LAN using the LAN connector and cable. Connect the blue RJ-45 cable into the blue PC port on the back of the system and to the Ethernet port on your computer. Power on the system. Select System Info > Admin Setup > LAN/H.323 > LAN/Intranet to configure the systems LAN/H.323 settings. The LAN & Intranet screen appears. If your LAN does not use DHCP, go to step 9. If your LAN uses DHCP, select Client in the DHCP field to enable the system to obtain an IP address from a server on your network. After you have changed the DHCP settings, a message lets you know that the system will have to be reset in order to save the changes. Select Yes. Another message informs you that the system is about to restart. Select the System Info icon to go to the System Information screen. Your system's IP address should appear in the IP Address field. You have finished this procedure. The rest of this procedure applies to LANs that do not use DHCP.

Note If the IP address field displays.waiting., the system did not get an address from the LAN. Check the LAN connection on the back of the system and try again. When the system is properly connected, the green light on the connector is illuminated and the orange light blinks.
10. Select Off in the DHCP field and manually enter the IP address, subnet mask, and gateway address provided by your system administrator. 11. Turn on your PC and make sure it is properly configured. 12. After you have changed the DHCP settings, a message lets you know that the system will have to be reset in order to save the changes. Select Yes. Another message informs you that the system is about to restart.
Connecting the System to a PC off the LAN
Do this if you need to use IP-based functions (display desktop, do a software update, use PolySnap) on a system that is not connected to a LAN.
Caution Your system must beconfigured as a DHCP server for this procedure. Do not use this procedure if the equipment is connected to a LAN.
Note To set your system as a DHCP server, the option Allow System to be a DHCP Server must have been enabled during a software upgrade of your system.

1. 2. 3. 4. 5.

Ensure that the PC and the system are both powered off. Connect the blue RJ-45 cable into the blue PC port on the back of the system and to the Ethernet port on your computer. Power on the system and the PC. Select System Info > Admin Setup > LAN/H.323 > LAN/Intranet on the ViewStation. Press the Up arrow on the remote control to go to the DHCP field and set it to Server. The system displays the message The system will now issue IP addresses to other PCs on the LAN. Continue? Caution Do not use this setting if your ViewStation is on a LAN. If you do, the ViewStation will provide IP addresses to the other computers on the LAN even though the LAN already has a DHCP server. Your IT personnel and system administrators will have to repair any network problems this causes.

6. 7. 8. 9.

Select Yes if you are absolutely certain you want to set your system as a DHCP server. Press Menu. The following message will appear: Power must be reset to save changes. Continue? Select Yes. Your ViewStation will automatically restart. It will now act as a DHCP server and will provide IP addresses to one or more PCs. Go to the System Information screen. You should see an IP address of 1.1.1.2, which is the IP address of your ViewStation. If your PC uses Windows 2000, go to step 14.

10. For Windows 95, Windows 98, or Windows NT 4.0, right-click the Network Neighborhood icon, and then right-click Properties. 11. When the Network box appears, select the Configuration tab, then double-click TCP/IP. 12. Select the IP Address tab. Make sure the Obtain an IP Address Automatically button is selected. Then click OK. 13. Go to step 18. 14. For Windows 2000, right-click the My Network Places icon, and then right-click Properties. 15. In the Network and Dial-up Connections window, right-click Local Area Connection, and select Properties. 16. In the Local Area Connection Properties window, double-click Internet Protocol (TCP/IP). 17. In the Internet Protocol (TCP/IP) Properties window, make sure the Obtain an IP Address Automatically button is selected. Then click OK. 18. Restart your PC.

Placing Test Calls

To verify that you have installed the endpoint equipment correctly, test each unit as follows:
Place an ISDN call from the unit. Place an IP call from the unit. From a suitable endpoint, place an ISDN call to the unit. From a suitable endpoint, place an IP call to the unit.
If you are able to complete all calls successfully, the unit is ready for use.
