Page 27: Dial Plan
The NBX system’s dial plan determines how the system handles calls. It defines the set of destinations that the system can reach, how to get to these destinations, and which telephone numbers to dial to reach these destinations. This chapter provides information about understanding, developing, and managing the dial plan.
Page 28: Dial Plan Concepts And Overview
2: D HAPTER Dial Plan Concepts The dial plan configuration file is an ASCII text file that implements the and Overview dial plan and specifies pretranslation (digit manipulation). The system is shipped with several default dial plan configuration files, typically, a 3-digit and a 4-digit file for each supported country.
Page 29: Call Process Flow
Dial Plan Configuration File Commands” later in this chapter. If you have entries in both the Least Cost table and the Internal table for the same purpose, the behavior of the dial plan can be confusing. 3Com recommends that you accomplish least cost routing using Internal Table entries.
Page 30: Nbx System Database
The NBX system database contains a default dial plan that is initially loaded at the factory and is reloaded if you purge the 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.
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 CAUTION: If you configure the Auto Attendant so that it can access any external number, you risk the possibility of toll fraud. You can reduce the possibility of toll fraud by explicitly putting specific external numbers into the outgoing dial plan table.
Page 33 Dial Plan Concepts and Overview Hybrid Mode Operation Using the Dial Plan If you map telephone buttons for some telephones but not others, you enable Hybrid mode (a mixture of standard and Keyset behaviors). The system provides a system-wide External Prefix setting, which allows the administrator to establish a prefix.
Page 34: Dial Plan Tables
2: D HAPTER Dial Plan Tables Dial plan tables contain information that controls how the system routes calls. Each dial plan configuration file consists of at least three dial plan tables. This section discusses these topics: Dial Plan Command Format ■...

Page 36 Least Cost table instead. To avoid such conflicts, you can accomplish least cost routing using only the Internal table. 3Com strongly recommends that, to keep the dial plan as simple as possible, you use only the Internal table for least cost routing.
Page 37 Dial Plan Tables 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. If the caller dials at least the minimum number of digits and not more than the maximum number of digits, the system waits 5 seconds and then routes the call based on the digits dialed.If the caller dials more than...
Page 38: Internal Dial Plan Table
2: D HAPTER Internal Dial The Internal dial plan table (table ID 1) defines how to handle calls placed Plan Table from internal devices, such as NBX Business or Basic Telephones, to a destination. A destination can be another internal device, such as a local telephone, or an external telephone line (Analog Line Card or Digital Line Card) that connects the NBX system to other facilities.
Page 39: Least Cost Routing Dial Plan Table
Least Cost table instead. To avoid such conflicts, accomplish least cost routing using only the Internal table. 3Com strongly recommends that you keep the dial plan as simple as possible by using only the Internal table.
Page 40: Dial Plan Pretranslators
2: D HAPTER Example: Users at site A dial 911 and the system uses the Internal table (table ID 1) to make the emergency call on one external telephone line. Users at site B dial 911 and the system uses table ID 4 to make the emergency call on a different external telephone line.
Page 41: Pretranslators For Incoming Calls
Dial Plan Pretranslators Pretranslators for For incoming calls, pretranslation reformats the dialed number before it is Incoming Calls passed to the Incoming dial plan table (Table ID 2). See “Incoming Dial Plan Table” later in this chapter. Incoming Pretranslator Example 1 If, for an incoming telephone call, the telephone company passes you 4-digit numbers from 6100 through 6199, the system can use a pretranslator to remove the first digit;...
Page 42: Pretranslators For Certain Outgoing Calls
2: D HAPTER Pretranslator Example 3 Assume that the telephone company passes 4-digit numbers to the system for each incoming telephone call (for example, numbers in the range 5200 through 5300). If the system uses 3-digit extensions in the range 200 through 300, you could define a single pretranslation operation to stripLead (remove) the first digit, for instance, the number 5 from an incoming number such as 5278, and pass the call to extension 278.
Page 43: Managing The Dial Plan Configuration File
Managing the Dial Plan Configuration File pretranslator to remove (stripLead) the first two digits from the internal extension number and add (prepend) the appropriate digit string. This pretranslator constructs the full telephone number. Example: If you use two different long-distance carriers at different times of the day to save costs, you can prepend different digit sequences to the outgoing dialed number to select which carrier you want.

This error is flagged in Reports. If a device has only a Normal table, no error is reported.
Page 53: Modifying A Dial Plan Configuration File
CAUTION: Modifications must be syntactically correct. Each time that the system imports a dial plan configuration file, it verifies the file for errors and displays the results. To avoid typing mistakes, 3Com suggests that you start with an existing dial plan (for example, one of the default plans that are shipped with the NBX system or a plan from another NBX system), modify it, and save it as a renamed file.
Page 54 2: D HAPTER Figure 8 Modify Dial Plan Dialog Box — Partial Display 3 Edit the dial plan configuration file. A single line of space is required between each dial plan entry. You can type a complete dial plan entry anywhere in the file.
Page 55: Outdialing Prefix Settings
You cannot mix 3-digit and 4-digit extensions within the same NBX system. The NBX 100 and the SuperStack 3 NBX systems both support 3-digit and 4-digit dial plans, although there are some differences in the extension ranges as noted in these tables.
Page 56 You must also manually change any device extensions so that they fall within the appropriate range. Note 2: The Superstack 3 NBX is shipped with a 4-digit dial plan. If you import any 3-digit plan, you must manually specify any 3-digit extension ranges that are not set by the imported plan.

Using a VTL Password Using a VTL If you want to allow users on one NBX system to place VTL calls to Password another NBX system and then place long-distance (toll) calls from that location (this is known as hop off), you can configure a VTL password. When an NBX system receives a VTL call from a user on another NBX system, it can allow that user to make long-distance calls if the incoming VTL call contains the password.

Page 155: Example Bridged Extensions Configurations
Creating and Managing Bridged Extensions You define any one telephone as either a primary telephone or a secondary telephone, but not both. If the telephone has an 1105 Attendant Console associated with it, the bridged extension functions for the telephone extend to the Attendant Console. For example, if you configure an NBX Basic Telephone with an associated Attendant Console, you can define that configuration as a primary telephone with up to 11 bridged extensions.
Page 156 3: D HAPTER EVICE ONFIGURATION and 1066, are defined as secondary telephones on which extension 1044 appears. On the 1055 telephone, buttons 10, 11, and 12 are configured as the three bridged extension buttons for the 1044 telephone. On the 1066 telephone, buttons 4, 5, and 6 are configured as bridged extension appearances.

Page 414: Overview Of Connextions
ONNE TIONS ATEWAY Overview of ConneXtions is a 3Com software product that allows you to use an ConneXtions appropriately configured Windows system as an H.323 gateway for use with NBX systems. H.323 gateways implement an ITU standard that allows telephone-like call connections to occur through an IP network.
Page 415: Windows-Based System
Installation Requirements the H.323 protocol presents special problems for firewalls because it requires additional processing. To minimize packet delay through a firewall, verify that the firewall is configured to give H.323 packets a high processing priority. During installation, you can select a range of TCP or UDP ports to use with H.323 connections to provide more flexibility when using firewalls.
Page 416 A: C H.323 G PPENDIX ONNE TIONS ATEWAY Processor, Memory, and Bandwidth Requirements Each G.711 call needs about 50 MHz on a Pentium II or 20 Mhz on a Pentium III. Each G.723 call needs about 128 MHz on a Pentium II or 75 Mhz on a Pentium III.
Page 417 Other System Requirements Each H.323 port requires 6 Mb of memory. 3Com recommends a PC with at least 128 Mb of memory. Disk storage requirements are minimal. In addition to memory and disk storage, the operating system needs: A compact disk for loading ConneXtions software.
Page 418: Connextions Software
A: C H.323 G PPENDIX ONNE TIONS ATEWAY can also be used to communicate with the IP router. This single NIC configuration is appropriate if the firewall, which separates Internet and intranet, is either unnecessary or is required by company policy. ConneXtions You use the NBX Resource Pack CD to install ConneXtions software.
Page 419: Verifying The G.723 Converter
Preparing for Installation Verifying the Installations that need G.723.1 audio compression require access to a G.723 Converter converter in Microsoft NetMeeting 2.1 or 3.01. NetMeeting must be installed on the same PC that holds the ConneXtions software, but the two cannot run simultaneously. G.723.1 does not appear as a selectable option in ConneXtions unless the converter is accessible.

Page 424: Overview Of H.323
An NBX ConneXtions H.323 Gateway provides connections similar to tie lines between existing NBX systems across an IP network. However, it can also support voice connections between a 3Com NBX Telephone and other H.323-compliant devices. ConneXtions H.323 Gateways support communication with: Extensions on other NBX systems that have a ConneXtions gateway.
Page 425 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 426: Standard Extensions
A: C H.323 G PPENDIX ONNE TIONS ATEWAY (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 427: The H.323 Connection
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 428: Connection Considerations
A: C H.323 G PPENDIX ONNE TIONS ATEWAY 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 429: 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 430 A: 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 431 Connection Considerations Most people notice latency when the end-to-end delay is above 200 ms. (The round-trip delay is typically no greater than 400 ms.) Conversations sound most natural when latency is below this range. Network latency can be measured by “pinging” the network connection, but the network connection is only part of the delay.
Page 432 A: C H.323 G PPENDIX ONNE TIONS ATEWAY Adaptive Jitter Buffering All IP network devices use buffers to retime the packets that they receive from a network. Retiming allows these devices to compensate for the variable delays that occur as the packets pass through an IP network. H.323 calls take different paths through a network so the ConneXtions gateway uses an adaptive “jitter buffer”...

Page 435 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 436: 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...
Page 437: Pbx Connections
Special Issues You can use Microsoft’s VPN Dial Up Networking (version 1.3) to establish a virtual private network connection between a roaming laptop and the NBX system LAN. One end of the VPN connection is in the laptop while the other end must be located in a VPN server between the router and firewall.
Page 438 A: C H.323 G PPENDIX ONNE TIONS ATEWAY Tie-line connections between NBX and PBX systems require technical people from both ends of the connection to collaborate in these major areas, discussed next: H.323 Interoperability ■ IP Addressing ■ Voice Ports ■...
Page 439 ■ 12 ports, 80 hours ■ On the SuperStack 3 system, 3Com offers 12, 24, 48, 72, and 100-port licenses. The administrator selects the maximum time for voice mail storage. If you choose to increase your existing level of port licenses, you can purchase additional 1-port incremental licenses.
Page 440: Class Of Service
A: C H.323 G PPENDIX ONNE TIONS ATEWAY 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 441: Alternate Gatekeepers
Checking Connections 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 447: Speed Dials
Placing Calls 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 448 A: C H.323 G PPENDIX ONNE TIONS ATEWAY 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 449: One Button Access
Placing Calls 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.
