LAN host name: Any system connected to a LAN must have a
LAN host name (netBIOS name) defined. This is sometimes called the computer name. An alias address may represent a terminal or it may represent a conference. Alias addresses must be unique within a zone. For example, within a zone there may only be one entity that uses the alias 3721005.
Rules for Assigning Prefixes and Numeric Aliases
In assigning prefixes and numeric aliases, it is critically important to observe certain rules:
MCUs and gateways provide services, so they must have
service prefixes assigned to them. Each service must have its own prefix. For example, an MCU or gateway will have a separate service prefix for each call speed that it provides.
MCU and gateway services work across zones only if used in
conjunction with a manually entered zone prefix.
If the system uses more than one gatekeeper, each gatekeeper
must have a zone identifier prefix.
The numeric aliases for terminals and conferences may begin
with the same initial digit(s) as any service prefix or zone identifier prefix. This is because PathNavigators parsing rule is that aliases are checked first and service prefixes are checked last.
The numerals used for service prefixes may not start with an
existing service prefix. Example: If 9 is selected as your access simplified dialing system service, then you may not create MCU or gateway service prefixes that begin with 9.
Local zone prefixes are not considered local service prefixes.
Therefore, if you have a local zone prefix of 408, you may still use 40 to designate a service.

Service Plans

A service plan assigns numeric prefixes to services on the network. Gatekeepers use service prefixes to route terminal requests to the appropriate provider of services. Services on the network are processed by media processors on the network. Within H.323, media processors are MCUs, gateways, and proxies. A service prefix is analogous to the digit 9 that you must dial to request an outside line from a PBX system; the systems response of connecting you to the requested outside line would be the service in this example.

System Services

System services include the following:
Conference on demand Call forwarding: set forward busy, set forward no answer, and
set forward unconditional.
Access simplified dialing Join or leave hunt group
System services only work within a zone. They do not work across zones. 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.

ISDN Requirements

The following paragraphs describe the requirements for ISDN PRI and BRI interfaces.

ISDN PRI

The PRI network interface is available for the ViewStation FX and VS4000.
Note Polycom ISDN PRI modules include an internal CSU for the PRI interface. The systems internal CSU can be disabled via the Admin Setup.
The PRI T1 needs to be provisioned for the ViewStation FX and VS4000 systems as follows:
Table 3-4. ISDN PRI Requirements Line settings ESF/B8ZS (default) Extended Super Frame B8ZS is modem standard for T1/PRI line encoding and framing Line termination type CPE (user side) only The required termination is built into the system and most access switches AT&T 4ESS, AT&T 5ESS, NI-1, NI-2, Siemens, Nortel DMS 100, and Nortel 250 These are standard protocols for North America Number of channels 23 B-channels dialable at 64 or 56 Kbps, and one D channel Ensure that you have 64 Kbps clear channel service Number of network interfaces Line build-out modes 1 (single PRI)
Supported PRI switch protocols
DSU+CSU (0 to 22.5dB attenuation), DSU-only (DSX 0-665 feet) Physical distance is offset by the settings in the user interface
Clocking Terminal Endpoint ID (TEI) Numbering D-channel slot number
Must be derived from the external network or the PBX 0-63 This identifies the PRI endpoint; the common default is 0 One local directory number per interface (23 channels) 24 Included to verify where the D channel is; this is where additional diagnostic information resides Values 0-31 service codes for GVPN/PN/UPN network-specific services
Call-by-call service codes
The PRI direct from the telephone service provider should support both data and voice for Polycoms voice add-on capability of systems.

Determining Usage

To get the best rate of return from PRI lines, they should be used as much as possible. To do this, look at the data and video traffic as a whole. Establish a reasonable ratio between the total bandwidth required if every device is in use and the number of lines provided. A ratio of 10:1 is fair for general use. If you use a PBX, access switch, or other data communications unit, the total number of lines into your customer premise equipment (CPE) can be allocated by channel to your equipment, according to the bandwidth required at any given time.
PBX Network Configuration
The PBX or other CPE that will be providing the ISDN PRI interface to the system must be able to provide a clock signal. Other than the clocking requirement, the rest of the ISDN PRI provisioning on the PBX is very similar to what would be requested of an outside ISDN provider.

ISDN BRI

All Polycom ISDN BRI interfaces are S/T-loop. ISDN BRI lines coming direct from a Telco are U-loop, so if your system is not behind a PBX or other private network, you must connect the BRI interface to BRI line(s) through an NT1 device capable of supporting multiple BRI lines. NT1 Devices that you may order through Polycom:
Single NT1 (2200-08406-001 or NT1) Triple NT1 (2200-08406-003) Quad NT1 (2200-08406-004 or NT1-QUAD)

Figure 3-3. Network Configuration (Behind PBX)
For ISDN BRI lines to be used from a PBX to a videoconferencing system, you must do these things in addition to meeting the other requirements.
Determine the interface type of the ISDN BRI network module
in the PBX (U-loop or S/T-loop). This will determine whether or
not you need an NT1 device between the PBX and the ISDN BRI interface of the videoconferencing system.
If the ISDN BRI network module in the PBX is S/T-loop, there
is a 500-foot limitation with S/T-loop ISDN. The module may still require a special jack with a resistor.
Ensure that the ISDN PRI or multiple BRI lines, on the public
side (from the Telco) are provisioned to carry data traffic as if it was connected directly to the videoconferencing systems as discussed in the appropriate sections above. Voice can be added but is not required. Items such as switch protocol, numbering plans, etc. are not necessary as those are determined by the PBX connecting to the ISDN lines from the Telco side.
Ensure that the ISDN BRI lines channels that connect to the
videoconferencing systems are mapped appropriately to the channels on the public network side of the PBX that connects to the Telcos ISDN cloud. This is critical also for the success of the inbound calls from systems outside the company to ensure that the ISDN number, provided to the videoconferencing system by the PBX, is routable in the public ISDN cloud and through the PBX to the appropriate videoconferencing system.
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.

Next, you must configure any required hunt groups with a direct inward dialing (DID) numbers, or local directory numbers. This enables other systems to call your system. Once you have configured the hunt groups, hook up the DCP ports to the system and follow the appropriate system installation procedures. Use the data module extension numbers for the port configurations on the system, and the DID/LDN number for the systems main number.
Note If you use Equal Access and a long distance reseller, the long distance reseller is probably not providing full 64 KBPS connectivity on long distance calls. In this case, you must set up the Definity to send long distance video calls through a long distance carrier that provides full-bandwidth connections.
You must configure a special COR for the system that uses a different ARS partition group. The ARS partition group will direct all long distance calls through separate routing patterns that have a KICK code configured. This KICK code tells the local carrier which long distance reseller to use and direct the call accordingly.

Site Considerations

When you select a site for videoconferencing equipment, consider the following factors:
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.

Cables Used with the Quad BRI Network Interface Module
The network cables are standard CAT5 cables. If you are connecting to a PBX, you may need a crossover cable.
To connect the Quad BRI network interface module to the system: 1. 2. Make sure your system is turned off. Connect the peripheral side of the Quad BRI network interface module to the system using the supplied network interface cable. This cable is color-coded blue on one end, green on the other.
Figure 4-3. Quad BRI Network Interface Module (Peripheral Side)
Connect the network side of the Quad BRI network interface module to the NT-1 device or to the ISDN network, as appropriate.
Figure 4-4. Quad BRI Network Interface Module (Network Side)
If you are using an NT-1 device, connect it to the ISDN network.
You are now ready to power on and configure the system.
Installing a PRI Network Interface Module
This section provides information about installing the PRI network interface module. This module is available for the ViewStation FX and VS4000. For performance specifications, cable diagrams and pinouts, and other technical information, please refer to Technical Information, on page 11.

External Power Supply

If the PRI network interface module loses power, it creates an alarm condition that may result in the service provider disabling the line. The PRI network interface must be connected to the external 12-volt DC power supply so that it does not lose power when the system is powered off. Connect the external power supply to an uninterruptable power supply (UPS) if possible. The external power supply is mandatory for installations in Europe and is strongly recommended where not mandatory.
You must use an external power supply if you use the internal CSU capability of the PRI T1 network interface module.

Channel Service Unit

In North America, the PRI T1 network interface module can be connected to an external Channel Service Unit (CSU). The CSU isolates the PRI from the network, and continues to transmit a signal to the network even if the PRI network interface module loses power or is disconnected. This prevents the line from being deactivated. A CSU is normally used only when the PRI network interface module is connected directly to a telephone company switch, not a PBX. Outside North America, CSUs are not used with PRI network interface modules. If you use an external CSU, connect an RJ-45 cable from the CPE equipment side of the CSU to the PRI network interface module.
ADTRAN Atlas 800 Plus E1 Module
Firmware If you are using an ADTRAN Atlas 800 Plus E1 Module, it must use firmware version G03b or later.
Channel Restarts Wait two to three minutes after the endpoint has been powered on and the PRI status icon has turned green before making or receiving calls with the ADTRAN Atlas 800 Plus. This allows time for channel restarts on the ADTRAN Atlas 800 Plus E1 module. If you place a call before channel restarts are complete, a Network Congestion message appears on the system. Incoming calls during this time will receive a Far Site Busy message.
