Page 30: Nbx System Database
The default dial plan for the SuperStack 3 NBX system is a 4-digit plan; for the NBX 100, it is a 3-digit plan. Changes that you make to any system settings, including changes made by importing a modified dial plan configuration file, are reflected in the database.
Page 31: Pretranslation
When you import a dial plan, some parameters of the system change immediately. Others change only when you reboot the NBX system. 3Com recommends that you reboot the NBX system each time that you change the dial plan. Rebooting the system disrupts service to the telephones. Plan to reboot at a time that does not inconvenience telephone users.
Page 32: System Features Affected By The Dial Plan Configuration
2: D HAPTER You can route incoming calls to the Auto Attendant port, and you can instruct the Auto Attendant to route these calls to any internal or external number. CAUTION: If you configure the Auto Attendant so that it can access any external number, you risk the possibility of toll fraud.
Page 33: Off-Site Notification
Dial Plan Concepts and Overview The NBX system applies any Class of Service restrictions that are associated with the user's telephone to determine whether to make a call. The system also uses any pretranslator that a device uses and performs any required digit manipulation operations before it actually transmits the digits on the Analog Line Card or Digital Line Card port.
Page 34: Dial Plan Tables

Page 37 Dial Plan Tables would collect all 4 digits of the extension. If the caller dials fewer than the Min number of digits, the system times out in 20 seconds. Example: If Digits = 2, Min = 4, and Max = 4, the system knows that if the first digit is 2, it must collect no less than 4 and no more than 4 digits before making the call routing decision.

Page 40: Adding New Dial Plan Tables
2: D HAPTER Adding New If you are sharing the system with another company or group and want Dial Plan Tables to control calls differently at the two sites, you can add a fourth table. Example: You assign one extension range to Company A and a different range to Company B.
Page 41: Pretranslators For Incoming Calls
Example: Say that the DDI/DID telephone numbers range from 508-555-4200 through 508-555-4299. The telephone company sends you the last 4 digits of the total telephone number. Internally, you want to use extensions 2000 through 2099. You can define a pretranslator to: Remove (stripLead) the first two digits of the incoming 4-digit ■...
Page 42: Pretranslators For Certain Outgoing Calls
2: D HAPTER Each device can specify only one DDI/DID pretranslator and one CLIP pretranslator. To create or modify a pretranslator, you either edit a dial plan configuration file and import it, or use the NBX NetSet utility and modify an existing dial plan configuration file. The system performs operations in ascending order of operation ID.
Page 43 When you place a call to an external telephone number, the system can use these pretranslator steps to create the full 10-digit number: 1 Remove (stripLead) the first two digits (20) from the internal extension number of the telephone making the call. 2 Add (prepend) the digit sequence 50855542 to the two remaining digits, creating the full DDI/DID telephone number.

To place a hop-off call to 555-1212 in area code 903 through the Atlanta system, a user on a remote system would dial 72919035551212. The 72 code sets up a VTL connection to Atlanta that incudes the Atlanta system’s VTL password, and the remaining digits are used to dial the number (9 accesses an outside line to obtain dial tone from the local carrier, 1 accesses the long-distance carrier, and the remaining digits specify the long-distance number).

List of Dial Plan The dial plan commands are described in this section. They are listed in Commands alphabetical order: ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ DestinationRoute Create Syntax DestinationRoute Create nRouteId szDescription Description Creates a route that specifies the primary and alternative destination device of a call (for example, which CO Line or Digital Line Card port over which to route the call).
Page 104 2: D HAPTER Example: This example creates destination route 3 and names it “Voice Application”: DestinationRouteEntry Create Syntax DestinationRouteEntry Create nRouteId nEntryId szExtension Description creates a destination route entry that identifies a single destination device or device list. If the specified destination route entry already exists, this command overwrites it with the new information.
Page 105 Syntax ExtensionLength nExtensionLength Description The length of extension numbers for system devices. The default is 3 for NBX 100 systems. The default is 4 for SuperStack 3 NBX systems. Arguments — specifies either 3 to designate a a 3-digit dial plan, or nExtensionLength 4 to designate a 4-digit dial plan.
Page 106 When you manually generate an extension number, verify that it is within the valid range. During a dial plan import operation, the system does not validate that existing extensions are within the specified range. 3Com recommends that you configure the dial plan strongly you define any devices in the system.

The Software ConneXtions software performs the protocol conversions between an NBX system and the international H.323 standards. To a system administrator, H.323 ports look like PSTN line ports. Both have extensions and are configured the same way but have different license requirements.

Overview of H.323 connection alive until one of the parties ends the connection. A call tear-down signal indicates to the network, and to the other party, when a call ends. On standard telephone networks, the telephone company uses this signal to determine when to start and stop charging for long distance calls, but long distance charges do not normally apply to H.323 calls.
Page 400: Standard Extensions
D: C H.323 G PPENDIX ONNE TIONS (G.711 and G.723), H.323 gateways negotiate the type of compression they use during each call setup. Negotiation ensures that the compression on the transmit side matches the decompression processing on the receiving side. With the frame and packet overhead, each G.723 channel needs about 19.2 Kbps of the available bandwidth.
Page 401: The H.323 Connection
POTS Adapters You can purchase circuit boards that plug into a personal computer and adapt an analog telephone (POTS) for use with an H.323 connection. H.323 Gatekeepers The gatekeeper is an H.323 entity on the network that provides address translation and controls access to the network for H.323 terminals, Gateways, and MCUs.
Page 402: Connection Considerations
D: C PPENDIX ONNE TIONS Connection As soon as an end-to-end connection has been set up, all three networks Considerations (local LAN, WAN, and remote LAN) are ready to pass voice packets. The NBX Business and Basic Telephones use their DSP to convert spoken words into digital voice packets.
Page 403: Quality Of Service
Connection Considerations Because so many devices share the same physical media on the Internet and on the local network, there is always the possibility of incomplete or degraded connections that arise from network congestion, device configuration, or addressing problems. Bridges, switches, routers, and firewalls can help to manage network congestion, conversions, and security.
Page 404 D: C H.323 G PPENDIX ONNE TIONS ATEWAY Bandwidth Bandwidth is the capacity to carry information. By using H.323, the same bandwidth that supports one uncompressed G.711 voice connection can, instead, support several compressed G.723 conversations with little noticeable difference in quality. Networks differ in the age of their equipment and in the quality of their service.
Page 405 Connection Considerations gateway generates a silence indicator or sends frames filled with silence, depending on the silence suppression mode. Connections Sometimes packet loss is caused by a poor physical connection. This type of packet loss is more likely to occur in a LAN than in a WAN. Typical causes are faulty wiring, connectors, and termination.

D: C H.323 G PPENDIX ONNE TIONS ATEWAY Quality of NBX systems address Quality of Service (QoS) issues using methods that Service Control are discussed in this section. Adaptive Jitter Buffering All IP network devices use buffers to retime the packets that they receive from a network.
Page 407 6-bit priority field within the IP header of every packet. Most routers examine this field and base their pass-through priorities on it. NBX systems are designed to use the default values that come with 3Com switches. If you use other routers, you may need to reprogram their diff-serv settings.
Page 408: Special Issues
D: C PPENDIX ONNE TIONS Special Issues This section describes issues related to H.323 telephony in general and to ConneXtions gateways in particular. These include: ■ ■ ■ ■ ■ ■ ■ Firewall Security Firewalls determine which packets can cross the boundary between a protected network (intranet) and the public internet.
Page 409: Outbound Calls
Special Issues 3Com recommends that a high-performance PC be dedicated to the ConneXtions software. The question of whether an operating system is adequately “secure” is a subject of debate. The concern is that Windows has many IP ports of its own.
Page 410: Gateway Load
To reduce the load on an H.323 gateway, you can connect it to an existing multi-port switch. For optimum performance, use switches that support 802.1(p and q). The 802.1(p and q) standard offers priority enhancement which NBX systems exploit. Most 3Com switches support this feature. Remote Access...

D: C PPENDIX ONNE TIONS Extension Delay Call setup times for digital connections, compared to analog connections, are instantaneous so there is no need to include a delay between the IP address and an appended extension. Incoming H.323 calls to an NBX system usually go directly to the Automated Attendant.
Page 415: Alternate Gatekeepers
Alternate A zone can contain only one gatekeeper at a time, although multiple Gatekeepers distinct devices can provide the gatekeeper function in a zone. Multiple devices that provide the RAS signaling function for the gatekeeper are called alternate gatekeepers. Each alternate gatekeeper appears to each endpoint as a distinct Gatekeeper.

Page 420: Placing Calls
D: C PPENDIX ONNE TIONS ■ ■ Placing Calls You can place an outgoing H.323 call from an NBX system in one of several ways, as discussed in this section. NBX system to use H.323 ports. IP Address Entry Depending on how you set up the dial plan, the most convenient way to place a call to a new number is to dial a ConneXtions extension list (configured within the dial plan), which provides a connection to an available H.323 port.
Page 421: Speed Dials
Extension Lists You can configure H.323 ports for single-digit access (usually 8) instead of a specific 3-digit line extension. The single-digit access allows the NBX system to select an available line port when you place an external call. Internet IP line ports and CO (central office) line ports must never be assigned to the same extension list because they use very different dial plans.
Page 422 D: C H.323 G PPENDIX ONNE TIONS Speed dial numbers can be system-wide or personal. System speed dial numbers (700-799) apply system-wide and are programmed by the system administrator. Personal speed dial numbers (601 through 699) apply only to an individual telephone; they are programmed by its owner. You can assign any of the first ten speed dial numbers in each type group, system or personal, to any Access button on a telephone.
Page 423: One Button Access
One Button Access You can configure an Access button on a NBX system to dial a complete H.323 (or switched) dial sequence. This procedure assumes that all buttons available for one-button access are configured in the first ten system (or personal) speed dial locations. To set up one-button dials: 1 In the NBX NetSet - Main Menu window, click Device Configuration.
