Page 29: Dial Plan
The NBX system’s 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. It covers these topics: Dial Plan Concepts and Overview Dial Plan Tables Dial Plan Pretranslators...
Page 30: 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 31: Call Process Flow
124. 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. For more information, see...
Page 32: Nbx System Database
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. NBX V3000 system — default 4-digit plan SuperStack 3 NBX system —...

Rebooting the system disrupts service to the telephones. Plan to reboot at a time that does not inconvenience telephone users. Pretranslation Pretranslation before they are passed to the appropriate dial plan table for subsequent routing. You can set the dial plan to perform pretranslation on incoming or outgoing calls.

For more information, see “TimedRoute Create” page Configuration File Commands” System Features The dial plan configuration affects several system features: Affected by the Dial Plan Configuration Keyset Mode Operation Using the Dial Plan If you map any telephone buttons that have LEDs to specific Analog Line...
Page 35: Dial Plan Tables
Example: When voice mail arrives, the NBX system dials the telephone number of the user’s pager. Typically, you use a system-wide prefix to designate the device or devices you want to use for outdialing purposes, including off-site notification calls. Example: If the user’s pager number is 800-555-3751, and the system-wide prefix digit is 9, the system dials 98005553751 to send a call to the user’s pager.
Page 36: Dial Plan Command Format
2: D HAPTER If the Least Cost Routing table exists, it takes precedence over the Internal table. If the system cannot find a Least Cost Routing table, it attempts to find a corresponding entry in the Internal table. If you have entries for the same purpose in both the Least Cost and Internal tables, the behavior of the dial plan can be confusing.

Page 39 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.

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 42: 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 43: Pretranslators For Incoming Calls
Example: Say that the DDI/DID (Direct Inward Dial/Direct Dial Inward) 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 sequence.
Page 44: Pretranslators For Certain Outgoing Calls
2: D HAPTER Commands” using the dial plan configuration file. 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.
Page 45 Example: If the DDI/DID telephone numbers range from 508-555-4200 through 508-555-4299, internally, you dial extensions from 2000 through 2099 to reach another internal telephone. 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.
Page 46: Managing The Dial Plan Configuration File
You can now edit the file with an ASCII editor. After you customize the new dial plan, Import it to the NBX system. see Dial Plan Configuration Files” 3Com recommends that you enter these commands at the top of every dial plan configuration file: Table Delete *...
Page 47: Importing And Exporting Dial Plan Configuration Files
The sample default files include examples of such things as timed routes and pretranslators. To preserve the default (sample) dial plan configuration included with the system, 3Com advises you to choose a unique file name different than any of the default (sample) dial plan configuration files so that you do not overwrite the sample default files.

The sample default files include examples of such things as timed routes and pretranslators.
Page 52: Generating A Dial Plan Report
2: D HAPTER You can specify a day of the week and a time by selecting entries from the Day/Time list boxes. This choice instructs the system to act as if the day and time you select are the current day and time. If you have timed routes defined in the dial plan, you use different day and time settings to determine whether the timed route works properly.

Consider these common dial plan problems: Dial plan table entries that point to nonexistent routes Timed route entries that point to nonexistent destination routes Destination route entries that point to nonexistent extensions or empty extension lists Timed route entries that overlap...
Page 54: 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 55: Outdialing Prefix Settings
NBX systems support 3-digit and 4-digit dial plans, although there are some differences in the extension ranges as noted in these tables. By default, the NBX 100 uses a 3-digit dial plan, and the NBX V3000 and the SuperStack 3 NBX use a 4-digit dial plan.
Page 56 Note 2: The NBX 100 is shipped with a factory default 3-digit dial plan. If you import any 4-digit plan, you must manually specify any 4-digit extension ranges that are not set by the imported plan.
Page 57 Note 2: The NBX 100 is shipped with a factory default 3-digit dial plan. If you import any 4-digit plan, you must manually specify any 4-digit extension ranges that are not set by the imported plan.

Telephones and Line Card ports reserve most of the extensions within the system. However, there are other extensions within the system. shows the default extension ranges for 3-digit and 4-digit dial plans. Modifying Extensions You can modify the extension number of any device in the system. Normally, you make changes only after you have changed the extension ranges for the NBX system, in order to align the extensions with the new ranges.
Page 62: Converting Extensions
2: D HAPTER Table 11 Modify Extension Operations (continued) Changing Extensions You can perform several operations through the Modify Extensions dialog Example: If you select Change Extension from the Operation list, the system replaces the selected extension with the number you type in the text box.
Page 63 To convert a dial plan between 3- and 4-digits, follow these steps: 1 If the conversion is part of a hardware upgrade: a Install the new hardware. b Install new licenses on the new system. You cannot move licenses from the old system to the new system. Licenses keys are tied to a system (hardware) ID number.

Managing An extension list contains extension numbers that are assigned and Extension Lists dedicated to specific dial tone facilities or to specific NBX applications (voice mail, Auto Attendant, and so on), or both.
Page 65: Adding An Extension List
Table 12 Extension Lists (continued) Extension List ID Description *0004 *0005 *0006 *0008 Within an extension list, you can assign a priority to each extension. When the system accesses an extension list, it tries to use the highest priority extension first. The highest priority is 1 and the lowest is 99. For example, If the extension list contains extensions that are assigned to T1 channels, you can assign unique priorities to each of the extensions.
Page 66 2: D HAPTER You may use the default extension number. 4 Type an asterisk preceding the extension number. By convention, the asterisk indicates that the number represents an extension list. 5 In the Name text box, type the name that you want to assign to the new extension list.

Page 112 2: D HAPTER 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). If the destination route already exists, this command removes all of its entries and operations, and overwrites its description with the new information.
Page 113 If the specified destination route entry already exists, this command overwrites it with the new information. During routing, the system checks the list of destinations in ascending Arguments nRouteId nEntryId the list of destinations in ascending nEntryId order, and uses the first available one.
Page 114 Description The length of extension numbers for system devices. The default is 4 for NBX V3000 systems. The default is 4 for SuperStack 3 NBX systems. The default is 3 for NBX 100 systems. Arguments — specifies either 3 to designate a a 3-digit dial plan, or nExtensionLength 4 to designate a 4-digit dial plan.
Page 115 Dial Plan Configuration File Commands Example: These commands define the extension range for telephones as 100 through 449, for call park as 601 through 609, for Auto Attendants as 500 through 599, for hunt groups as 450 through 499, and for external lines as 600 through 799.
Page 116 2: D HAPTER The default value for a 3-digit system is 750, and for a 4-digit system is 7250. Typically, systems do not use all of the extensions from 600 through 799 (or 6000 through 7999). If, however, the system uses all of these extensions and needs another one, it starts looking from the beginning of the range and selects the first unused one.

Page 414: Negotiated Connections
D: C PPENDIX ONNE TIONS The H.323 protocol addresses these main areas: Negotiated The H.323 protocol adds negotiated call setup and tear-down capabilities Connections to Internet Protocol (IP) connections. It exists because Internet protocols were designed to deliver text messages and computer files in data packets.
Page 415: Standard Extensions
Elsewhere on the LAN (local or remote), the destination telephone detects its address, recovers the frames, extracts the bit stream, and reproduces the voice. While LANs have enough bandwidth to support uncompressed digitized voice transfers, WAN bandwidth is less generous. For this reason, compression is often used to squeeze the digitized voice into a smaller bandwidth that can be carried across an Internet in smaller packets.
Page 416: The H.323 Connection
D: C PPENDIX ONNE TIONS Personal Computers Microsoft NetMeeting software supports H.323 voice connections over the Internet. The personal computer must be equipped with Internet access, a sound system, and a microphone. The current version of Microsoft NetMeeting (3.01) cannot conveniently place calls through the Auto Attendant because it has no way of entering extension digits after it reaches an IP address (the Auto Attendant).
Page 417: Connection Considerations
After an IP connection has been established, the ConneXtions software begins a series of H.323 exchanges by using TCP packets on the IP connection. These H.323 exchanges set up the call and negotiate the type of voice compression that is used. They also cause the remote NBX (or PBX) system to begin setting up the remote end of the connection.
Page 418: Quality Of Service
D: C H.323 G PPENDIX ONNE TIONS ATEWAY Logical Connections Locally, every device on an NBX LAN has the same physical access to the local network traffic as any other device. Consequently, addresses control connections because devices can only read information that is addressed to them.
Page 419 Connection Considerations The frequency response, dynamic range, and noise of a voice conversation depend on the voice representation. If all data packets reach their destination, the system provides voice of a specified quality. The H.323 standard accommodates alternative voice compression standards that allow users to trade some voice quality for bandwidth by selecting a different compression standard (G.711 or G.723).

Page 421: Quality Of Service Control
Connection Considerations Jitter Momentary transmission delays can affect the pace of a conversation and, if severe, cause the voice to “break up.” This is known as “jitter.” All voice-over-internet devices have a “jitter buffer” at the receiving end whose purpose is to absorb jitter. It does this by delaying the first packets that arrive by some significant amount (from 50 to 200 ms).
Page 422 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 423: Special Issues
NBX ConneXtions does not support the Layer 3 (IP) 6-bit TOS/DS priority field. However, it is usually possible for IP routers to use these priority schemes if they are configured to prioritize H.323 packets. Special Issues This section describes issues related to H.323 telephony in general and to ConneXtions gateways in particular.
Page 424 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.
Page 425: 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).
