■ CALL — Call audio traffic

Off — No audio traffic on the T1 link. Flashing — Audio traffic is present.

■ CARD — Card Software Status

NBX Cards and Devices 39

Green — The card has finished downloading software from the NCP and all software processes have started successfully.

Amber — A problem with one or more of the software processes running on the card. The card automatically reboots itself if it detects a problem with any of its software processes.

■ DSP — Reserved for future use

■ NCP — Network Call Processor communications status

Amber — The card is trying to establish contact with an NCP. Green — The card has established contact with an NCP.

■ LNK — Ethernet link status

Green — The 10/100 Uplink port is connected to a 10Mb or to a 10/100 Mb hub or switch.

Red — The 10/100 Uplink port is connected to a 100 Mb hub or switch.

Off — There is no connection to the 10/100 Uplink port.

■ ACT— Ethernet activity

Rapid blink — Data is passing into or out of the card through the 10/100 Uplink port.

■ 10/100 Uplink — This RJ-45 Ethernet connector connects the E1 card

to an external LAN hub or switch. You can use this connector to isolate E1 traffic. If the E1 Digital Line Card is used in a SuperStack

3 NBX V5000 Gateway Chassis, do not use this connector because the chassis has an Ethernet connector to connect the chassis to the LAN.

■ Console — This DB-9 connector provides an RS-232 (DCE) TTY

terminal connection for maintenance access.

If you require an alternative (bare wire-end) cable to use with the ISDN PRI Digital Line Card, contact your 3Com NBX Voice-Authorized Partner.

CAUTION: This equipment does not operate when the main power fails.

The ISDN BRI-ST (Basic Rate Interface) Digital Line Card (Figure 12) has four separate ports, each of which accommodates two B channels and one D channel. Each B channel carries user data at 64 Kbps and the

channel operates at 16 Kbps. If the two B channels are bonded, the

D transmission rate is 128 Kbps.

CAUTION: The BRI-ST Digital Line Cards are not approved for use in the United States or Canada.

■ Status Lights — Each port has three status lights:

CONSOLE

■ D — On when this signaling channel is active.

■ B1 — On when this data channel is active (a call is in progress).

■ B2 — On when this data channel is active (a call is in progress).

During the Auto Discover process:

■ Each status light turns amber briefly, starting with span 1 (channels

D, B1, and B2) and continuing through span 4 (channels D, B1, and B2). After approximately 30 seconds, the B1 status light on all four spans turns green for approximately 1 minute. All lights turn off when the Auto Discover process is complete.

After you connect an ISDN BRI span to a port:

■ The D light turns green if the span is operating properly and turns

amber if there is a problem. For a span that is operating properly, when the NBX system initiates or receives a call on a B channel, the corresponding light initially turns amber. When the call is answered, the light turns green.

■ Console — This DB-9 connector provides an RS-232 (DCE) TTY

terminal connection for maintenance access.

CAUTION: This equipment does not operate when the main power fails.

10BASE-T Uplink Card The 10BASE-T Uplink Card provides eight 10BASE-T Ethernet ports to

connect 3Com Telephones (or other 10BASE-T devices) to the LAN. The Uplink Card (

Figure 13 NBX Uplink Card (3C10370)

3C10370

3Com NBX Uplink Card

3C10370) replaces the 10BASE-T Hub Card (3C10115).

NBX Cards and Devices 41

The NBX 10BASE-T Uplink Card contains these lights and connectors:

■ Status Lights (PWR and 1 through 8) — These lights indicate the

status of power to the hub and the status of the 10BASE-T ports.

■ Ethernet Hub Ports (8) — These RJ-45 MDI-X ports connect devices

to the LAN.

Analog Terminal Card Each Analog Terminal Card allows connections for up to four analog

(2500-series compliant) telephones and Group-3 fax machines. When an Analog Terminal Card senses that a port is being used for fax transmission, it switches that port to reliable mode. Unlike voice transfers, which drop packets due to congestion, reliable mode transmissions take as much time as needed to ensure that there are no lost packets. However, reliable mode also uses twice the bandwidth.

CAUTION: If you are using the 3Com SuperStack ARPS (Advanced Redundant Power Source) as a backup power supply for the SuperStack 3 NBX V5000 Gateway Chassis, you can have no more than 2 Analog Terminal Cards of Models 3C10117, 3C10117A, or 3C10117B-INT per Gateway Chassis. This restriction does not apply to the 3C10117C Analog Term ina l Ca rd.

3105 Attendant Console 3C10405A

The 3Com Attendant Console provides attendant (receptionist) access and monitoring for up to 100 extensions.

Requires NBX R4.3 or higher and a Group 2 license

NBX systems also support legacy 3Com telephones: 2101 Basic Telephones, 1102, 2102 and 2102-IR Business Telephones, and 1105 Attendant Consoles.

CAUTION: To avoid damage to the 3Com telephone, do not connect a 3Com telephone or Attendant Console directly to a standard telephone line. Although the RJ-11 connector for a traditional telephone fits into the 3Com telephone’s RJ-45 jack, the electrical interfaces are not compatible and the telephone will not work.

Legacy Link Devices 3Com Legacy Link Blades allow you to migrate Nortel Norstar and

Meridian telephone users to an IP infrastructure. The 3Com Legacy Link Analog Blade is a multiport analog handset gateway card that fits into an NBX chassis.

Third-party Devices

and Applications

Legacy Link cards put significant traffic on an NBX 100 backplane. 3Com recommends that you install no more than two Legacy Link cards in an NBX 100 chassis. If you have Digital Line Cards (T1/E1) in the same chassis, you must connect the Digital Line Cards to an Ethernet switch via the uplink port on the front of the cards to reduce backplane traffic. These limitations do not apply to the SuperStack3 NBX V5000 Chassis.

3Com works with third-party suppliers to provide a range of devices and software applications that are compatible with NBX systems. For more information on third-party offerings, see your 3Com NBX Voice-Authorized Partner.

46 CHAPTER 1: INTRODUCTION

Optional Software The NBX Resource Pack CD includes a number of optional components.

Two applications are counterparts of two NBX system hardware devices:

■ NBX Complement Attendant Software (CAS) runs on a PC and

provides the functions of an Attendant Console. You install the Complement Attendant Software from the NBX Resource pack CD. You must purchase a license and use the NBX NetSet utility to install it before you can use CAS.

■ pcXset™ Soft Telephone runs on a PC and provides most of the

features of a 3Com Business Telephone. The NBX system comes with one pcXset license. To use more than one pcXset client with an NBX system, you must purchase additional licenses and use the NBX NetSet utility to install them. You add a pcXset client as a telephone in the NBX NetSet utility and specify the host PC’s NIC MAC address as the device identifier.

In addition, these software applications and documents are available on the NBX Resource

■ NBX Call Reports enables you to retrieve the call detail records that

are kept on the NBX system, present them in report format and export them in a format suitable for other reporting applications. No license required. NBX Call Reports is available from the NBX Resource Pack CD and from within the Downloads tab of the NBX NetSet utility.

Pack CD:

■ NBX TAPI Service Provider (NBXTSP) provides the interface between

the NBX system and the Microsoft Telephone API to enable software applications to use NBX Telephone services and features.

■ Desktop Call Assistant is a TAPI-based program that allows you to

dial calls from your computer screen.

■ Palm Dialer enables you to look up a telephone number in your Palm

Address Book application and then place a call to that number on an NBX 2102-IR Business Telephone (a legacy device) through the phone’s infrared port.

■ NBX ConneXtions allows you to use an appropriately configured

Windows system as an H.323 gateway for use with NBX systems.

■ NBX Media Driver works with the NBXTSP to provide external

software applications access to the features of the NBX system.

■ 3Com Network Supervisor is an evaluation version of the 3Com

network element management system.

NBX Licensing 47

■ NBX LabelMaker is available through the NBX NetSet utility. It

enables you to define custom telephone button labels. You can create, print, and save the labels for later use.

■ 3Com Telephone Local Configuration Application is a PC-based

utility that enables you to manually configure the basic settings for NBX devices that do not have an LCD display, such as the 3100 Entry Telephone and the 3105 Attendant Console.

NBX Licensing Each NBX system is shipped with a total-device-limit license that controls

the total number of devices that you can configure on the system. However, there are other factors to consider when determining what your system can support. Your configuration must conform to all of these limits:

■ The limit imposed by the total system license (explained next)

■ The individual limits on certain device types (explained later in this

topic)

■ The license requirements for some hardware and software

What Counts Toward the Total Device Limit?

NBX systems count many physical devices and certain software applications as devices toward the total device limit:

■ Physical Devices — Each 3Com Telephone, each Analog Terminal

Adapter, each channel on a Digital Line Card, and each port on an Analog Line Card counts as one device. Physical device limits are listed

Ta bl e 10.

■ Software “Devices” — Each NBX Media Driver port counts as one

device. Each installation (client) of the pcXset Soft Telephone application counts as one device.

What Does NOT Count Toward the Total Device Limit?

The NBX systems do not count most applications toward the total device limit, although some may be governed by license limits. Examples: voice mail ports, automated attendant ports, Call Park zones, System Speed Dials, and any other item with “None” in the second column in

Ta bl e 10.

48 CHAPTER 1: INTRODUCTION

Individual Device

Limits

Licensed Device

Limits

How the System

Limits Interact

Certain individual device types are limited to a maximum per system because of internal product rules. For example, the NBX Analog Line Card has 4 ports. Although each of these ports counts as a device, the NBX system architecture limits the system to 180 Analog Line Cards (4 x 180), and thus the system can support a maximum of 720 not 1500 analog line ports.

Certain devices and applications have limits that are governed by licenses. Device licensing is explained in detail in

“Device Licenses” on page 52.

Your 3Com NBX Voice-Authorized Partner can provide details on available incremental device licences.

As you add devices to an NBX system, you must keep in mind all of these limitations:

■ To ta l device limit for the system

■ Individual device limit for certain device types

■ License limit for certain device types

■ System memory

Example: Your NBX V3000 has the memory upgrade installed, it is licensed for 1500 total devices and you want to configure 450 telephones:

■ You configure 6 NBX Analog Line Cards, and 12 NBX Analog Terminal

Cards (for analog telephones and FAX machines). The total device count is now (6 x 4) + (12 x 4) = 72.

■ You then configure 450 3Com Telephones.

The total device count is now 522. You can configure 978 additional devices (1500–522).

■ You want to configure 200 Attendant Consoles, but, because the

individual device limit for Attendant Consoles is 100, you can configure only 100 Attendant Consoles.

The total device count is now 622. You can configure 878 additional devices (1500–622).

■ You want to add Virtual Tie Lines (VTLs), but you can add only 48

because that is the maximum license level available for VTLs.

NBX Licensing 49

VTLs do not count toward the device limit, so the total device count remains at 622. So, after you add 48 VTLs, you can still configure up to 878 additional devices.

Table of Maximum

Device Counts

Ta bl e 10 lists each NBX device and application, with information on

whether it counts toward the total device count and the maximum number allowed per NBX system.

For the current device and license configuration on your system, see

NetSet > Operations > Licenses as well as the Usage Report

NBX

accessible from the Licenses screen.

Some of the limits in Tabl e 1 0 can be affected by your dial plan. The 3-digit dial plan does not support enough extensions to allow you to reach all the device limits.

NBX Licensing Summary Notes

■ NBX cards, Analog Terminal Adapters, and legacy devices (1102,

2102, 2102-IR Business Telephones, 2101 Basic Telephones, and 1105 Attendant Consoles) do not require a license. The number of these devices is governed solely by the system device license.

■ The NBX V3000 comes with four NBX Messaging ports and a limit of

400 hours of message storage. (A messaging port is used for each Automated Attendant session and each voice mail session.) If you want more than 4 ports, you must purchase and install additional NBX Messaging licenses. To go above 12 NBX Messaging ports, you must install the memory upgrade (3C10240) if you haven't already done so to upgrade the device limit. If you purchase additional NBX Messaging capacity, message storage hours are limited only by available disk space, however, the NBX administrator can establish limits on the number of messages, message length, and retention period.

Group Device

Licenses

NBX Group Licensing provides a flexible system of licensing NBX telephones and attendant consoles. For licensing purposes, NBX devices are grouped according to the features the device can support. Lower cost devices that have fewer features are part of lower numbered License Groups while the more capable full-featured devices are part of the higher numbered License Groups.

Group 2 Devices:

Dynamic License

Assignment

NBX Group Licensing is a dynamic system that assigns licenses in the most efficient manner. A Group License can activate devices belonging to that group or devices with fewer features. For example, a Group 2 license normally activates Group 2 devices but it may also activate Group 1 or Group 0 devices. If a device needs a license and no license is available for that group, the system “loans” a license from a higher license group if a license is available in that group.

License loans are automatic. The system dynamically assigns available licenses to devices to achieve the most efficient use of the installed licenses. Dynamic allocation can cause a more valuable license to be used for a less valuable telephone. For example, using a Group 2 license for a Group 0 device might be desirable as an interim solution, but if you later add a Group 2 device, you would probably want to purchase a Group 0 license for the Group 0 telephone and use the Group 2 license for the Group 2 device.

These examples demonstrate the flexibility of NBX Group Licenses.

Example 1— All devices in the same License Group: You purchase and install a package of ten Group 2 Licenses on your SuperStack 3 NBX system and then add five 3102 Business Telephones, one 3103 Manager’s Telephone and one 3105 Attendant Console for a total of seven Group 2 devices. The system has three Group 2 licenses still available.

Example 2 — Borrowing from the next highest License Group: You add a 3101 Basic Telephone (Group 1 device) to your SuperStack 3 NBX system, which has three Group 2 licenses available. You do not add a Group 1 license to the system. The system checks for the availability of a

NBX Licensing 55

Group 1 license. Since no Group 1 licenses are available, the system assigns a Group 2 license to the 3101 Basic Telephone. The system now has two Group 2 licenses available.

Example 3 — Borrow from the highest License Group: You add two 3100 Entry Telephones (Group 0 device) to your SuperStack 3 NBX system, which has two Group 2 licenses available. You do not add a Group 0 license to the system. The system checks for the availability of a Group 0 license, then checks for the availability of a Group 1 license, and since there are no Group 0 or 1 licenses available, assigns the Group 2 licenses to the 3100 Entry Telephones. The system now has no licenses available.

Figure 18 shows the section of the License Usage Report that

displays device license usage.

Figure 18 License Details Information

The first column in the License Usage Report shows the number of device licenses currently in use. The second column shows the number of licenses in each License Group that have been installed on the system.

Example 4 — Dynamic License Group Adjustment: You add another 3103 Manager’s Telephone (Group 2 device) to your SuperStack 3 NBX system, which has no licenses available in any group. The system will not enable the new telephone. You could add another Group 2 license, but it would be more cost-effective to add a less expensive Group 0 license instead. After you add a Group 0 license, the system automatically reassigns licenses in this manner:

■ Releases one of the Group 2 licenses that was assigned to one of the

3100 Entry Telephones.

■ Assigns the new Group 0 license to the 3100 Telephone.

■ Assigns the released Group 2 license to the new 3103 Telephone.

56 CHAPTER 1: INTRODUCTION

The system now has no licenses available.

Example 5 — Manual License Group readjustment: You add another 3103 Manager’s Telephone (Group 2 device) to your SuperStack 3 NBX system, which has no licenses available in any group. Instead of adding a Group 0 license, as shown in Example 4, you could manually remove one of the telephones from the system to free a license. For example, you could use the NBX NetSet utility to remove the 3101 Basic Telephone. Since that telephone was using a Group 2 license, removing the telephone makes a Group 2 license available.

Group License Notes

■ To view the number of Group Licenses you have installed on your

system open the License Summary page in the NBX NetSet utility, Operations > Licenses. To view how the number of Group Licenses have been allocated, including licenses loaned to different groups, open the License Usage Report in the NBX NetSet utility, Operations > Licenses > Usage Report.

■ To achieve the best licensing configuration, you should always add

license keys to the system (Operations > Licenses > Add License) before you add devices.

Upgrading Device

Licenses from R4.X to

R5.0

■ If you are removing a telephone to manually readjust licenses, you

should first make sure that Auto Discover Telephones is disabled (System Configuration > System Settings > System-wide) to ensure that the telephone is not automatically added to the system again.

■ A basic NBX V3000 system includes fifteen Group 2 Licenses.

Group Licensing is not available on systems prior to R5.0. Licensed devices that are installed on a system at the time that system is upgraded to R5.0 will have their licenses converted to appropriate License Groups:

■ 3101 and 3101SP Basic Telephone licenses convert to Group 1

Licenses

■ 3102 Business Telephone licenses convert to Group 2 Licenses

■ 3105 Attendant Console licenses convert to Group 2 Licenses

NBX Licensing 57

Rebooting from R5.X

to R4.X

If you reboot an R5.0 system to an earlier software version, these license conversions are in effect:

■ Device licenses that were converted to Group 1 and Group 2 licenses

during the upgrade to R5.0 are active as 3101, 3102 and 3105 licenses.

■ Group 1 licenses applied after the upgrade to R5.0 are converted to

3101 licenses.

■ Group 2 licenses applied after the upgrade to R5.0 are converted to

3102 licenses.

■ Devices introduced at R5.0, 3103 Manager’s Telephones, 3100 Entry

Telephones, and 3106C and 3107C Cordless Telephones will not be recognized. These devices were not supported prior to release R5.0.

Group Licensing, 3105 Attendant Consoles, and R4.X Software

If you reboot to R4.4 or R4.3 from R5.0, Group 2 licenses are converted to 3102 device licenses, which means that a 3105 Attendant Console, which is a Group 2 device, could become unavailable. The following examples show what happens to 3105 Attendant Consoles when you reboot from R5.0 to R4.4 or R4.3.

Example 1: Your system is running R4.3 (or R4.4) software. The system has one 3105 Attendant Console installed and you have one 3105 device license installed on the system. You upgrade the system to R5.0. The 3105 device license becomes a Group 2 license and the 3105 continues to operate. You reboot the system to R4.3 or R4.4 and the 3105 continues to operate under the original 3105 device license.

Example 2:

Your system is running R4.3 (or R4.4) software. The system has one 3105 Attendant Console installed and you have one 3105 device license installed on the system. You upgrade the system to R5.0 software, and then add another 3105 and a Group 2 license. You reboot the system to R4.3 or R4.4. One of the 3105 Attendant Consoles continues to work and the other does not because the Group 2 license that was used by the 3105 while operating under R5.0 is converted to a 3102 device license. To enable the 3105 under R4.4 or R4.3, you need to add a 3105 device license.

Example 3: Your system is running R4.3 (or R4.4) software. The system has one 3105 Attendant Console installed and you have two 3105 device licenses installed on the system. You upgrade the system to R5.0 software, and then add another 3105 and a Group 2 license. You reboot the system to R4.3 or R4.4. Both 3105s continues to work.

60 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

Introduction This guide uses the following definitions for administrators, users, and

callers on the NBX system:

■ Administrator — The person responsible for managing and

maintaining the LAN. This person has “administrator” privileges on the system

■ User — A person with user login privileges on the system

■ Caller — A person calling into the system

International Feature Support

For international users, the following features and devices warrant special attention.

Power Fail Transfer For the Power Fail Transfer (PFT) feature, is available only in North

America.

CAUTION: You should have access to a mobile or analog telephone that is connected to your standard PSTN.

Analog Terminal

Connectors

The NBX Analog Terminal Adapter, the ATA port on the NBX V3000, and each port on the NBX Analog Terminal Card may require a telephone connector for use outside North America. Contact your 3Com NBX Voice-Authorized Partner for information on country-specific requirements.

Language Support The NBX Resource Pack CD includes these localized components:

■ Telephone tones and cadences that match those used by telephone

companies in different countries

■ Localized online user documentation

■ Localized voice prompts

If the required language is not provided in the voice prompts, which you can load and activate using the NBX NetSet utility, you can record new Automated Attendant main menu and system-wide Time-dependent greetings. For information on how to modify an Automated Attendant, see the “Automated Attendant” section in Chapter 6, “NBX Messaging,” in the NBX Administrator’s Guide.

Installation Requirements 61

Installation Requirements

Electrical

Requirements

Verify that you meet the prerequisites that are detailed in the following sections before you install the NBX system.

3Com does not support more than one NBX system on a local area network. You can connect NBX systems over a WAN using VTLs, as described the NBX Administrator’s Guide, however, installing more than one NCP on a LAN can cause unpredictable results.

Verify that the site meets the following electrical requirements.

■ Each NBX chassis requires an electrical connection.

■ The NBX system should have its own breaker-protected circuit that

uses the standard, three-wire, grounded configuration.

■ Verify that there are enough outlets and circuit capacity in the chosen

location to supply power to the NBX chassis and any auxiliary equipment that you install, such as a paging amplifier and an MOH device. The label on each chassis lists the electrical requirements of the system.

■ You can eliminate the power adapter for a telephone by using a

powered Ethernet cable. See

“Connecting Power to a 3Com

Telephone” in Chapter 3 for more information.

CAUTION: 3Com strongly recommends that you use UL listed surge suppression devices for the telephones and the local telephone lines and an uninterruptible power supply for each NBX chassis.

Environmental

Requirements

You can install the NBX system in any clean, dry, well-ventilated location. Take these environmental guidelines into consideration:

■ The area must be safe from water damage. A wet basement, a utility

closet, or an area near a window are not proper locations.

CAUTION: Do not use the NBX system outdoors.

■ The area must be safe from physical interference. For example, do not

put the chassis where it might be struck by a swinging door or where cables might be disturbed by a door or by people passing by.

■ Do not install the NBX system in an area that is exposed to strong

electromagnetic fields, dust, smoke, or airborne debris.

62 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

■ Verify that the installation site has sufficient cooling and air circulation

to maintain ambient temperatures from 0 °C through 40 °C (32 °F through 104 °F

) and a humidity range of 5% to 85%, noncondensing.

Physical

Requirements

Local Telephone

Service

When you install an NBX system, verify that the installation site meets these physical requirements:

■ The NBX system should be installed in a secure area. Telephone service

and voice messaging are crucial business services. Protect them from tampering or accidental interference.

■ To rack-mount an NBX system, use a standard 486-mm (19-in.)

equipment rack, properly installed and grounded according to the manufacturer’s instructions.

■ The NBX V3000 is 42 mm (1.6 in.) high and 355 mm (14 in.) deep.

All data connections are on the front of the chassis and power connections are on the back.

■ The SuperStack 3 NBX V5000 Chassis is 13.3 cm (5.25 in.) high

and 30.5 cm (12 in.) deep. All data connections are on the front of the chassis and power connections are on the back.

■ The NBX 100 chassis is 10.5 in. (264.7 mm) high and 23 cm (9 in.)

deep. All connections are on the front of the chassis.

■ Allow at least 8 cm (3 in.) of space on either side of the NBX chassis

for proper ventilation.

Before you install the NBX system, be sure that the installation site meets the following local telephone service requirements:

■ The local telephone company has installed local telephone lines and

assigned telephone numbers.

■ If necessary, you have extended the wires from a centrally located

telephone interface panel to the installation site.

■ Each analog telephone line has dial tone.

CAUTION: 3Com strongly recommends that you use UL-listed surge suppression devices on all local telephone lines.

■ If you are installing an optional BRI-ST, T1, or E1 Digital Line Card,

verify that the telephone company has installed BRI-ST, T1, or E1 lines and run them to the installation location.

Installation Questions 63

Installation Questions

Who Should Install

the NBX System?

Does the Telephone

Company Need to Be

Involved?

If you have not already planned the installation, the following topics discuss issues that you may encounter when you install the telephone system.

A technician who understands Ethernet 10BASE-T and 100BASE-T cabling requirements and telephony configuration should install and configure the system. If you are using the IP capabilities of the NBX system, the technician also needs to understand IP, subnetworks, and DHCP (Dynamic Host Configuration Protocol).

After the initial installation, the local administrator should be able to install additional telephones and manage the system.

If the cabling scheme has not been designed and installed, you should consult a qualified network design engineer. Although it is not difficult to set up a small 10BASE-T or 100BASE-T LAN, a well-designed network should accommodate future growth without redesign. NBX system documentation does not explain the workings of Ethernet or IP, or the requirements for cabling a network.

You must rely on the local telephone company to provide one or more loop-start lines and the telephone number or numbers. A fax machine can connect to the NBX system through an Analog Terminal Adapter.

Is Any Additional

Equipment Required?

CAUTION: To avoid damage to any 3Com telephone, do not connect it directly to a standard telephone line. Although the RJ-11 connector for a traditional telephone fits into the 3Com telephone’s RJ-45 jack, the electrical interfaces are not compatible and the telephone will not work.

You may need some of the following components:

■ To configure the NBX system, you need a computer equipped with a

browser, such as Microsoft Internet Explorer Release 5.5 or higher, a network interface card, and a CD-ROM drive. You also need to provide IP configuration parameters for the system.

■ Computers that use Computer Telephony Integration (CTI)

applications need an operating system that supports the Microsoft TAPI 2.X standard, such as Windows XP or Windows 2000, and a browser to download the TAPI-related NBX support software through the NBX NetSet utility.

64 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

■ If you choose to install the NBX system in an equipment rack, you

need a standard 486 mm (19 in.) rack.

■ You may need 10BASE-T or 100BASE-T Ethernet cable and connectors

to connect the telephones to the hub.

■ 3Com strongly recommends that you use surge suppression devices

on all local telephone lines.

■ 3Com telephones and attendant consoles that support Power over

Ethernet (PoE) do not come with AC power adapters. You can power these devices with any IEEE 802.3af-compliant power source or with optional AC power adapters. The packing sheet that ships with each device shows the device power options.

What External

Devices Can Connect

to an NBX System?

What Effect Does an

NBX System Have on

a LAN?

The following devices can be connected to an NBX system:

■ Music-on-hold device, such as a radio, tape player, disk player, or

computer sound card, equipped with a line out (600 ohm) connection can be connected directly into the NCP to provide audio for callers waiting on hold.

■ Third-party 10BASE-T or 100BASE-T Ethernet hubs and switches.

■ An ISDN (Integrated Services Digital Network) router, Frame Relay

Access Device (FRAD) router, or Voice Over IP gateway.

■ A WAN. You can access NBX systems located at branch offices

through a wide area network (WAN). Before you use the NBX system for voice over the WAN, verify that the WAN offers adequate bandwidth, and that the gateways can be configured to provide the correct routing information.

■ External paging amplifier. The NBX system includes an RJ-11 jack to

connect an externally powered paging amplifier.

■ Standard telephone for power-fail situations. In the United States, you

can connect a standard POTS (Plain Old Telephone Service — 2500-series compatible) telephone to an RJ-11 connector on the front of an NBX Analog Line Card or an NBX V3000.

A 10 Mbps Ethernet LAN can support a fully configured, fully utilized

100 system. A 100 Mbps Ethernet LAN can support a fully

NBX configured, fully utilized NBX SuperStack 3 system or NBX

V3000 system. That is, a 10 Mbps Ethernet LAN with 200 “voice devices” (3Com telephones and outside telephone lines) can support the toll-quality audio provided by the NBX

100 system even when all 200 devices are in use.

Installation Questions 65

Similarly, a 100 Mpbs LAN can support toll-quality audio with a fully configured SuperStack 3 NBX system or NBX

V3000 system. If you use an Ethernet switch, verify that it supports the 802.1P and 802.1Q specifications.

Silence Suppression and Bandwidth

Silence suppression enables you to reduce network traffic. When silence suppression is enabled, the NBX device detects silence in the audio stream, such as a pause in conversation, and stops sending packets. The receiving NBX device generates white noise for the periods represented by silence indicator packets so that the listener does not hear true silence and worry that the call has been disconnected. The receiving NBX device can be another 3Com telephone, or for external calls, it can be an analog line port or a channel on an NBX Digital Line Card.

A careful listener might notice the difference between generated and actual background noise, so silence suppression is turned off by default. Silence Suppression settings result in a small compromise to audio quality. Do not enable Silence Suppression unless you are trying to solve bandwidth constraint issues.

You can enable or disable silence suppression for the entire system or for individual telephones and line card ports.

NBX System Quality of Service

Quality of Service (QoS) is a way to allocate resources in data switches and routers so that data can be prioritized, with the most time-critical data receiving higher priority. At Layer 2, the NBX system supports Ethernet 802.1Q, “Standard for Virtual Bridged Local Area Networks,” and its associated specification, 802.1P, “Standard for Local and Metropolitan Area Networks, Supplement to Media Access Control (MAC) Bridges: Traffic Class Expediting and Dynamic Multicast Filtering.” These IEEE Ethernet standards define how Ethernet packets can be prioritized.

At Layer 3, the NBX supports IP Precedence, also called IP Type Of Se rv ic e (ToS), to specify the class of service for each packet. The default hexadecimal value for NBX system IP ToS settings is 0xb8.

66 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

Low-bandwidth Connections

You can configure a telephone to operate in lower-bandwidth environments such as a single B channel of a BRI ISDN line or other links with bandwidth as low as 56 Kbps.

■ The preferred method for enabling a low-bandwidth connection is to

select G729 audio, forcing the device to use lower-bandwidth compressed audio when communicating with other system devices.

■ Alternatively, you can configure the telephone as a low-bandwidth

device by disabling some of the internal features such as paging, conferencing, and music-on-hold. A check box in the NBX NetSet Device Configuration screen automatically selects the best parameters for low-bandwidth connections.

You can also connect an NBX Telephone to the system over a broadband connection and that is not considered a low-bandwidth connection. See the NBX Administrator’s Guide for information about connecting a remote telephone over a broadband connection.

Before You Begin Installation

■ Test set

■ Four rack screws appropriate to the rack

Important Safety Information 67

Important Safety Information

Before you install or remove any components or perform any maintenance procedures on the system, you must read the following safety information.

WARNING: Verify that each NBX 100 Chassis is set to the correct voltage for your country requirements. The voltage is indicated on the voltage selector switch next to the main cable inlet on the front panel of each chassis. (See

Figure 19 NBX 100 Voltage Selector Switch

Figure 19.)

The label to the left of the voltage selector

230 volts

230

115 volts

115

switch shows the 115 and 230 volt selection positions. If the incorrect voltage for your country is set, use a small flat-blade screwdriver to toggle the switch up or down on each chassis.

The NBX V3000 and the SuperStack 3 NBX V5000 work automatically with either 115 volt or 230 volt power, so they have no mechanism for changing voltage.

WARNING: The system must be installed in a secure (locked) area.

The components and telephones of the NBX system are electronic devices. To avoid injury and damage to the equipment, follow these important safety precautions when you install, use, or service it:

■ Allow only qualified personnel to install and remove the unit.

■ Always connect the unit to a grounded (protective earthed) outlet to

comply with international safety and EMC standards.

■ Read and understand all instructions.

■ Always disconnect a device from its power source before you clean it.

CAUTION: Each of the two power supply units in a SuperStack 3 NBX with redundant power supplies has its own overcurrent protection device which operates independently — the overcurrent device for one power supply does not protect the second power supply. You must connect both AC power cords to provide power to both of the power supplies.

68 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

■ Do not disassemble components of the system. If you suspect that a

card, chassis, or telephone is defective, call a service representative.

■ Do not use this product near water. Do not install this product or a

telephone in a damp area, such as a

■ Never cover or block the ventilation holes on the chassis or

telephones. Proper ventilation is required to ensure normal operation of each component and to avoid component failures.

■ WARNING: Never push objects into ventilation holes on the chassis or

telephone. Electrical voltages in system components can cause bodily harm.

■ Do not use the telephone during an electrical storm. Lightning poses

remote risk of electric shock through any telephone system.

■ Never use a telephone that is near the source of a gas leak to report

the leak.

■ Each NBX system and chassis is equipped with a three-prong

grounding plug. Do not defeat the protection offered by the plug by clipping the grounding prong or by using an adapter to connect the system to a two-wire power source.

basement.

■ Do not staple the power cord or otherwise attach it to building

surfaces.

■ Do not use any AC power converter on a 3Com device other than the

one that is shipped with the device. On 3Com PoE-compliant devices, the power converter is an optional component.

■ Power Cord Set:

■ For European countries, see Tab le 12. If your country is not listed

specifically, use the power cord set information for Europe.

■ For countries outside of Europe, you must use a power cord set

that complies with the relevant national standards for cable type and appliance coupling.

System

Hardware

Recording MAC

Addresses

Unpack the system components and examine them. Depending on the size and configuration of the system that was ordered, there may be multiple chassis and line cards. If you have not received all components, contact your 3Com NBX Voice-Authorized Partner.

Before you begin to install the hardware, you can perform optional steps:

■ Recording MAC Addresses

■ Optionally Upgrading NBX Memory

After you install the system disk drive, you should record the MAC addresses of the ports that interface with CO equipment. If you will be installing optional cards into a chassis, 3Com recommends that you install one card at a time, and that you install the cards in the order of the MAC addresses of the ports on the card. This process ensures that the NBX system assigns sequential, contiguous groups of device extensions to each board. If you enable the Auto Discover process to configure the cards, you can then use the NBX NetSet utility to view the MAC address of each individual port.

A well-organized physical configuration can simplify:

■ Management of incoming telephone lines, by associating line card

ports with specific telephone numbers

■ Troubleshooting, by associating groups of channel numbers with

specific cards

■ System expansion

NBX V3000

■ To determine the MAC address of the analog lines of the NBX V3000,

view the label on the back of the NBX

V3000. The MAC address is

labeled FXO MAC Address. All four analog line ports share one MAC address. After the ports are discovered by the NBX Auto Discover process, they are differentiated in the NBX NetSet utility by a channel number, 1-4.

Optional NBX Cards

■ To determine the MAC addresses of the ports on optional NBX Analog

Line Cards, NBX Analog Terminal Cards, and NBX Digital Line Cards,

Installing the NBX System Hardware 75

view the MAC address label attached to each card. MAC address labels are located on the component side of NBX cards. All four ports on a card share one MAC address and they are differentiated by a channel number, 1-4. After a card is inserted into a chassis, the MAC address is not visible.

On Analog Line Card 3C10114, which is no longer in production, each port has a different MAC address and port addresses are consecutive. A label on the card shows the base MAC address, which is the address for port 1. The other three ports are incremented versions of the base MAC address.

Optionally Upgrading

NBX Memory

Mounting an NBX 100

Chassis

The NBX V3000 and SuperStack 3 NBX can accept a memory upgrade module. If your system requires a memory upgrade, see the instruction sheet that comes with the memory kit:

■ NBX V3000 Memory Upgrade Kit — 3C10240

■ SuperStack 3 NBX Memory Upgrade Kit — 3C10233

To mount the Call Processor chassis in an equipment rack or on the wall, you need:

■ Two mounting brackets (supplied with the Call Processor)

■ Four mounting screws (supplied with the Call Processor)

■ Phillips screwdriver

■ Drill and drill bit (wall-mount only)

■ Level (wall-mount only)

■ 19-in. equipment rack (for rack mounting only)

76 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

Mounting the NBX 100 Chassis in an Equipment Rack

To mount the NBX 100 chassis in an equipment rack:

Verify that the equipment rack is properly installed and grounded and that the installation area is properly ventilated.

1 Attach the two mounting brackets securely to the sides of the NBX 100

chassis, using the upper and lower holes in each of the brackets and the two holes near the front of the chassis. See

Figure 20 Attaching Rack Mounting Brackets to the NBX 100 Chassis

Figure 20.

2 Install one screw into each vertical rail of the rack. Leave a space of at

least 6.5 cm (2.5

in.) between this location and any other equipment in

the rack. Do not tighten the screws. Thread them just far enough so that they are

secure. The slots on the bottom of the Call Processor chassis mounting brackets slip onto these screws.

3 Lift the chassis and slip the keyed slots of the mounting brackets onto the

two screws you installed in Step 1.

4 Hold the chassis in place and install a mounting screw in the top keyed

slot of each bracket.

5 Tighten all four screws securely.

Mounting the NBX 100 Chassis on a Wall

To mount the NBX 100 system chassis on a wall:

Before you wall-mount a chassis, prepare an area by attaching a suitable mounting surface securely to the wall studs. For effective cooling air flow,

Installing the NBX System Hardware 77

do not mount multiple chassis side by side. If you do, one chassis draws in warm air from the other, limiting the effectiveness of the cooling fans.

1 Install the brackets at the back of the chassis, as shown in Figure 21.

Figure 21 Attaching Wall Mounting Brackets to the NBX 100 Chassis

2 Use the dimensions shown in Figure 22 to mark the locations where you

will drill the pilot holes into the mounting surface.

Figure 22 Chassis Wall-mount Dimensions

465 mm (18.25 in)

89 mm (3.5 in)

63 mm (2.5 in)

CAUTION: If you wall-mount the NBX 100 chassis, you must attach the chassis securely to a plywood mounting board which is firmly attached to the wall. A fully configured 6-slot chassis can weigh up to 13.5 kg (30 lb).

3 Drill pilot holes at the locations you marked. 4 Install the two lower mounting screws.

Do not tighten the screws. Thread them just far enough so that they will support the weight of the NBX 100 chassis.

78 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

5 Lift the chassis and slide the two keyed mounting brackets over the

screws in the wall.

6 While holding the chassis in place, install screws into the top holes of

each mounting bracket, and then tighten all four screws.

Installing the

SuperStack 3 NBX

System

The SuperStack 3 NBX V5000 System is composed of the SuperStack 3 NBX Call Processor and one or more SuperStack 3 NBX V5000 Chassis. The Call Processor contains a factory-installed disk drive and call processor circuit board. The chassis are used to contain the interface cards. You are now ready to mount the SuperStack 3 NBX Call Processor in a rack.

Rack-mounting the SuperStack 3 NBX Call Processor

To install the SuperStack 3 NBX Call Processor, mount it in an equipment rack and apply power. For an overview of the Call Processor and its components, see

“SuperStack 3 NBX Gateway Chassis” in Chapter 1.

To mount the SuperStack 3 NBX Call Processor, you require the following tools and materials:

■ Four mounting screws

■ Phillips screwdriver or wrench

Verify that the equipment rack is properly installed and grounded, and that the installation area is properly ventilated.

1 Install one screw into each vertical rail of the 19-inch rack. Leave at least

6.5 cm (2.5

inches) above other equipment in the rack.

Do not tighten the screws. Thread them just far enough so that they are secure. The slots on the bottom of the Call Processor mounting brackets slip onto these screws.

2 Verify that the Call Processor mounting brackets are securely installed on

the front of the box.

3 Lift the Call Processor and slip the keyed slots of the mounting brackets

onto the two screws you installed in Step 1.

4 Hold the Call Processor in place, install a mounting screw in the top hole

of each bracket, and then tighten all four screws securely.

Installing a Second

Disk for Disk

Mirroring

You are now ready to mount the NBX Gateway Chassis. For an overview of this chassis, see

“SuperStack 3 NBX Gateway Chassis” in Chapter 1.

The tools, materials, and procedures for rack-mounting the NBX Gateway Chassis are essentially identical to those for mounting the SuperStack 3 NBX Call Processor. For more detailed information, see

“Installing the

NBX System Hardware” on page 74.

Disk mirroring is supported on the SuperStack 3 NBX V5000 only. Disk mirroring provides the ability to run a second disk in parallel with the

first.

This section describes how to install your second disk when you are setting up your NBX system. While the primary disk is already mounted in your Network Call Processor chassis, the second disk (if you purchased one) is packaged separately for you to install. If you are not installing a second disk with your NBX system, you can skip this section and proceed

“Powering Your NBX System” on page 80.

Disk Mirroring is an optional feature. If you do not install a second disk when you first install your Network Telephone System, you can purchase an upgrade kit at a later time.

CAUTION: To avoid damage to electronic circuits, always wear an anti-static grounding strap when handling the disk drive or NBX system components. When you ground the strap, do not ground it to an NBX chassis because the chassis is not grounded until you install it in a properly grounded setting.

To install an additional disk drive for disk mirroring:

1 Install the key code for your disk mirroring license. 2 Shut down system software. 3 Turn off power to your system. If your SuperStack 3 NBX Call Processor

has redundant power supplies you must disconnect both supplies.

4 Remove the disk drive tray on your Network Call Processor. 5 Unpack the second disk drive and install it in slot number 2 of the disk

tray.

6 Connect the ribbon cable correctly. 7 Re-insert the disk drive tray.

After you add power to the system, disk synchronization begins automatically and finishes in approximately 60 to 90 minutes, depending on the amount of information on disk 1 that must be mirrored on disk 2.

80 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

Powering Your NBX

System

Configuring NBX System Networking

To turn on power to the NBX system and the optional NBX chassis, follow these steps:

1 Attach a power cord to the back of each unit. For an NBX 100, a

SuperStack 3 NBX, or a chassis, attaching the power cord applies power to the unit. For an NBX

V3000, you must also press the power button on

the back of the unit to the ON position.

2 Allow approximately 3 minutes for the system to complete the boot

process. Examine the status lights (LEDs) on the front panel to ensure that the

system is running properly:

■ For a description of NBX V3000 status lights, see Figure 1 on page 22.

■ For a description of SuperStack 3 NBX status lights, see Figure 2 on

page 24.

■ For a description of NBX 100 status lights, see Figure 4 on page 28.

You are now ready to establish network/LAN Connectivity. See

“Configuring NBX System Networking” next.

Configuring the networking for the NBX system involves these steps:

■ Establishing IP Connectivity

Establishing IP

Connectivity

Modifying Default IP

Settings

■ Modifying Default IP Settings

■ Establishing LAN Connections

■ Configuring the NBX System IP Address

You need IP connectivity to use the NBX NetSet utility to configure and manage the NBX system.You do not need to install any special software to run the NBX NetSet utility, but your computer must have Microsoft Internet Explorer 5.5 or higher, which enables access to the NBX NetSet utility, the configuration interface for the NBX system.

Each NBX system is shipped with default IP settings. The default IP address is part of a block of addresses reserved by the Internet Engineering Task Force (IETF) for use on private IP networks, that is, networks that do not connect to the Internet.

Configuring NBX System Networking 81

CAUTION: Connecting two NBX systems to the same subnetwork (for example, using IP addresses 10.233.20.100 and 10.233.20.200 for two NCPs) is unsupported.

With most installations, you need to change the IP settings of the

system to conform to the network. The IP settings include:

NBX

■ Host Name — A name for the system, up to 30 characters in length,

including spaces, underscores, and hyphens.

■ IP Address — An IP address for the NBX system that is consistent with

your local area network. Consult your network administrator if you need assistance.

■ Default Gateway — An IP address for the gateway through which

you access the NBX system. If all devices (telephones, adaptors, and cards) are on the same subnet as the NCP, you do not need to specify a gateway IP address. Consult your network administrator if you need assistance.

■ Subnet Mask — An IP address mask that is consistent with your local

area network. Consult your network administrator if you need assistance.

To help you determine if you need to make changes to the NBX system IP settings, see

Tab le 15, later in this section. To avoid address conflicts with

devices on your local network, change the IP settings of NBX system before you connect the system to the LAN.

Summary of how to change the IP settings of the NBX system:

■ Temporarily change the IP address of your computer to conform with

the default IP settings of the NBX system.

■ Connect your computer to the NBX system.

■ Use the NBX NetSet utility to modify the IP settings of the NBX system.

■ Restore the IP settings of your computer and reconnect it to the LAN.

■ Connect the NBX system to your local network.

82 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

To change the IP settings of the NBX system:

1 Use a category 5 Ethernet crossover cable to connect the computer’s

network interface card (NIC) directly to your NBX system Ethernet port. By connecting the computer directly to the NBX system, you isolate the

system from the network and eliminate the influence of routers and proxy servers.

2 Record the existing IP settings on the computer so you can restore them

later.

3 Change the IP settings of your computer to:

IP address: 192.168.1.191 Default gateway: 0.0.0.0 Subnet mask: 255.255.255.0

CAUTION: Do not set your computer address to 192.168.1.192 because that IP address is used temporarily during system startup. If you use that address for your computer, a conflict results and the system might not start properly.

4 Reboot the computer so that the new settings take effect. 5 Start a browser. 6 To access the NBX NetSet utility, enter the following address into the

browser’s address field:

192.168.1.190

This is the default IP address of the NBX system. If the connection attempt fails, check the browser’s Proxy Server setting

and verify that it is configured for a direct connection. Also, check the Connection setting and verify that it is set for a direct LAN connection, not a dial-up connection.

After you connect, you can log in to the NBX NetSet utility using the default administrator user name and password. See the next topic,

“Configuring the NBX System IP Address” for instructions on configuring

the NBX IP settings.

CAUTION: If you change the administrator password, you cannot retrieve (return) to the default, nor can you retrieve your new password if you forget it. If you make any password changes, record them in a safe place.

Configuring NBX System Networking 83

Ta bl e 15 describes possible network environments and the configuration

needed to enable IP connectivity to the NBX system.

Ta bl e 15 IP Addressing and the NBX System

Local IP Environment NBX System Configuration

No IP networking currently in use

You do not need to change the IP settings in the NBX system, but you probably need to configure the IP

settings in the computer that you use to communicate

with the NBX NetSet utility. Set the computer’s IP parameters to these settings:

■ IP address: 192.168.1.191

■ Default gateway: 192.168.1.1

■ Subnet mask: 255.255.255.224

If you connect the LAN to the Internet in the future, your Internet service provider gives instructions on how to configure the IP settings of devices on the network. You must change the IP settings of the NBX system at that time.

CAUTION: Do not set your computer address to 192.168.1.192 because this IP address is used temporarily during system startup. If you use that address for your computer, a conflict results and the system may not start properly.

Private IP network, no subnets You probably need to change the NBX system IP address to conform with the

existing IP addressing scheme. You must change the NBX system IP address (192.168.1.190) if that address is

already in use on the network or if you are using a different range of addresses.

Private IP network, with subnets You probably need to change the NBX system IP address to conform with the

existing address space. You must change the NBX system IP address (192.168.1.190) if that address is already in use on the network.

You must change the NBX System subnet mask (255:255:255:0) if it does not conform to the network subnet scheme.

You must change the NBX system default gateway from 0.0.0.0 to the IP address of the default gateway for the subnet where you install the NBX system.

Internet connectivity; addresses provided by the Internet Service Provider.

Internet connectivity; addresses provided from address block controlled by the client’s organization.

You must change the NBX system IP address, default gateway, and possibly the subnet mask. Ask the ISP to provide a fixed IP address, subnet mask, and default gateway. You must have a fixed IP address for the NCP.

You must change the NBX system IP address, default gateway, and possibly the subnet mask. Ask the local network administrator to provide a fixed IP address, (the

NBX NCP does not support DHCP or BOOTP) a subnet mask, and a default

gateway.

LAN

Establishing NBX V3000 LAN Connections

Connect the NBX V300 system to your LAN using the Ethernet port. This port can operate at 10 Mbps and 100 Mbps; it automatically senses the speed of your LAN. Check the NCP status lights to verify network connectivity:

For a description of NBX V3000 status lights, see Figure 1 on page 22.

Establishing NBX 100 LAN Connections

Connect the NBX 100 Call Processor to your network using either the BNC 10B2 connector (3C10110C only) or the 10BT UPLINK MDI-X port.

For a description of NBX 100 status lights, see Figure 4 on page 28.

The 10B2 connection and the Uplink port on the 3C1011C Call Processor are two different connection points for a single port. They cannot be used simultaneously.

If you use the Uplink connector, be sure to program the switch or router on the other end for 10 MB operation.

Configuring NBX System Networking 85

You do not need to connect cards to each other within a chassis. They are connected by the chassis backplane.

Do not connect telephone lines or 3Com telephones yet.

Establishing SuperStack 3 NBX V5000 LAN Connections

Connect the SuperStack 3 NBX Call Processor to your LAN using the Ethernet 1 port. The Ethernet 2 port is a fail-over port that is active only if the Ethernet 1 port experiences a link failure. This port can operate at 10 Mbps and 100 Mbps; it automatically senses the speed of your LAN.

Establishing SuperStack 3 NBX V5000 Chassis LAN Connections

Connect the NBX chassis to your LAN using one of these:

■ The 10 Mbps shared connector — Operates at 10 Mbps only

■ The upper 10/100 Mbps connector — Operates at either 10 Mbps or

100 Mbps and automatically senses the speed of your LAN

■ The lower 10/100 Mbps RJ45 connector — Operates at either

Mbps or 100 Mbps and automatically senses the speed of your

10 LAN

The SuperStack 3 NBX V5000 Chassis 3C10200B is an updated version of the 3C10200. The update removed the 10 Mbps shared connector and improved the switch-over performance of the Ethernet ports so that both ports have link prior to switch-over.

For a description of SuperStack 3 NBX status lights, see Figure 2 on

page 24.

You do not need to connect cards to each other within an NBX chassis. They are connected by the chassis backplane.

Do not connect telephone lines or 3Com telephones yet.

Test Connectivity After the NBX system finishes its reboot operation and you have restored

your computer’s original IP settings, test connectivity to the NBX system.

1 Open a browser on your computer. 2 Type the IP address you assigned to the NBX system in the browser’s

address box, and then press Enter. The NBX NetSet utility login screen should appear in your browser.

86 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

Connecting Cards and Devices

Connecting Analog

Line Cards

After you configure and test the NBX system, you are ready to add cards into the optional chassis and attach optional devices such as Music On Hold.

You can install cards with the power on to the chassis. To connect and configure an NBX Analog Line Card:

1 Remove the blank faceplate from one of the slots. 2 Verify that the edges of the card ride in the chassis guide slots, and then

slide the card in until you feel slight resistance. Press firmly on both sides of the front of the card until you feel it seat in the connector, and then tighten the two knurled knobs.

If you cannot seat the card with light pressure, remove it and check for obstructions.

3 After you seat the card, wait at least 2 minutes for the card to initialize. 4 Use the NBX Auto Discover feature to configure the card. The Auto

Discover feature finds each line card port and assigns extensions. For more information, see

Configuration” on page 92.

3Com recommends that you install the cards in MAC address order. This practice makes it easier to diagnose and troubleshoot problems.

“Using Auto Discover for Initial System

Mapping Line Card Ports to Telephone Lines

You can run the system using the default configuration, but to have complete control over telephone operations, you need to know which telephone line is assigned to which analog line port so that you can map

telephone lines to telephones and manage lines for maximum

CO performance. Use the NBX NetSet utility to quickly reassign extensions.

When you connect the telephone lines, the order in which the telephone lines deliver calls matches the order of Line Card port extensions. For example, connect the line that rings first to the port with the lowest numbered extension, connect the next telephone line to next-lowest extension, and so forth. Extension numbers for Line Card ports are assigned based on the first unused extension number. Therefore, the extensions vary from system to system.

Line Card ports are labeled on the front panel. The first connector, labeled PFT (Power Fail Transfer), accepts a standard POTS (2500 touch-tone series compatible) telephone. If there is a power failure, this port

You can install cards with the power on to the chassis. To connect and configure the digital line cards:

1 Remove one of the blank faceplates from the chassis. 2 Install the card securely.

Verify that the edges of the card ride in the chassis guide slots, and then slide the card in until you feel slight resistance. Press firmly on both sides of the front of the card until you feel it seat in the connector, and then tighten the two knurled knobs.

If you cannot seat the card with light pressure, remove it and check for obstructions and alignment problems.

3 Wait at least 3 minutes for the card to initialize. 4 Use the Auto Discover feature to configure the digital line card. The Auto

Discover feature finds each port on each digital line card and assigns port extensions.

Use the Auto Discover feature to configure telephones and analog line cards before you enable Auto Discover for digital line cards. For more information about the Auto Discover feature, see

“Using Auto Discover

The Auto Discover process finds each port on each Analog Terminal Card and assigns port extensions.

Connecting an

Analog Terminal

Adapter

If you are installing one or more Analog Terminal Adapters (ATA), install them after installing chassis cards.

To install an ATA:

1 Connect the analog telephone or fax machine to the analog port on the

ATA. The analog port on a 3C10120B ATA has a picture of an analog telephone beside it. See

Figure 23. The analog port on a 3C10400 ATA is

labeled POTS (Plain Old Telephone Service). See Figure 24.

The Analog Terminal Adapter may require a telephone connector for use outside North America. Contact your supplier for more information on country-specific requirements.

2 Connect the Ethernet port on the ATA to the LAN. The Ethernet port on a

3C10120B ATA is the connector on the far left side. On the 3C10400 ATA, the Ethernet port is labeled LAN.

Ethernet port on the ATA. The 3C10120B Ethernet port has a picture of an NBX telephone beside it. The Ethernet port on the 3C10400 ATA is labeled PC.

4 Connect the AC power adapter to the AC power connector on the ATA.

If you are using a powered Ethernet cable instead of the AC adapter, see

“Using Power over Ethernet with an ATA” next.

Connecting Cards and Devices 89

5 Plug the AC power adapter into a wall outlet. 6 Use the Auto Discover feature to configure the ATA. For more

information about Auto Discover, see

“Using Auto Discover for Initial

System Configuration” on page 92.

7 If the ATA is connected to a fax machine, configure the port for fax

usage:

a Open the NBX NetSet utility and go to Device Configuration > ATA. b Select the ATA from the list and click Modify. c Enable the check box labeled Fax Machine, then click Apply.

Configuring an ATA port for fax operation optimizes the performance for inbound and outbound faxes. If you make a voice call using the ATA device (for example, if you use the telephone portion of the fax machine), the quality of the audio may be affected. If you make a VTL call using the ATA device, the audio may be unusable. If you configure the port for fax operation, expect lower quality voice calls on that port. If you configure the port for voice calls, the performance is not optimized for faxes.

Using Power over Ethernet with an ATA

The 3C10120B requires the use of a splitter device to accept Power over Ethernet (PoE).

The 3C10400 ATA can accept power over the Ethernet cable. It meets the IEEE 802.3af standard for Power over Ethernet. See

Ta bl e 16 for power

connection instructions. The 3C10400 ATA is a Class 3 PoE device.

The 3C10400 ATA can also accept power from an AC power adapter plugged into a wall socket. If you supply power to the ATA using an AC power adapter and then also supply power on the Ethernet cable, the ATA uses the Ethernet power source. If you supply power to the ATA over the Ethernet cable and then also connect the AC power adapter, the ATA continues to use the Ethernet cable power source. If you connect both power sources to the ATA and later remove the Ethernet cable, the ATA switches to use the AC power adapter.

Using Auto

Discover for Initial System Configuration

Using the Auto Discover feature simplifies initial system configuration by adding information about new devices to the configuration database. “Devices” include telephones, Analog Line Card ports, Digital Line Card channels, Analog Terminal Adapter ports, 3Com Attendant Consoles, and “virtual devices” such as the pcXset Soft Telephone and the ConneXtions H.323 Gateway.

Before you use the Auto Discover process to configure telephones and attendant consoles, you should review the procedures in “

Telephones and

Attendant Consoles” in Chapter 3.

After a device has been discovered, the Auto Discover process does not find that device again. To remove a device from the system, you must use the NBX NetSet utility to manually remove the device and its database record.

Licensed devices will not be discovered until after you have entered the appropriate Group License to the system. For more information on Group Licensing, see “

Device Licenses” on page 52.

labeled “new user,” assigns the next lowest available extension number to the profile, and enters the information into the configuration database.

Auto Discover Telephones finds both Analog Terminal Cards and Analog Terminal Adapters.

By default, the Auto Discover process assigns extension number 1000 (4-digit Dial Plan) or 100 (3-digit Dial Plan) as the first telephone extension. You can use the NBX NetSet utility to specify a new extension starting number. To simplify Auto Attendant configuration, you should start a range at a base number, for example, 1000/100, 2000/200, 3000/300, or 4000/400. The default Auto Attendant assumes that extension 1000 (4-digit dial plan) or 100 (3-digit dial plan) is the extension of a human attendant (receptionist).

■ A fully initialized telephone displays its extension and the date and

time. If there are no extensions available, the Auto Discover process fails, and the telephone’s display panel continues to display the telephone’s MAC address.

■ If you are adding devices that do not have a display panel, such as

3100 Entry Telephones, connect the devices one at a time and then refresh the Device Configuration > Telephones list after you connect a device to see the extension assigned to that device.

■ If you are installing a 3Com Attendant Console, connect it after you

have discovered all of the telephones. The Auto Discover Attendant Consoles process maps all existing telephone extension to the Attendant Console.

■ If you are adding licensed devices to the system, the devices will not

be discovered until you add the appropriate Group License to the system. For more information on Group Licensing, see

“Device

96 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

Disabling the Auto

Discover Feature

NBX System

Operating Modes

After you finish the Auto Discover process for the initial configuration, you can disable it so that the NCP does not continue to search for added devices.

To disable the Auto Discover feature:

1 Log in to the NBX NetSet utility using the administrator username and

password.

2 In the NBX NetSet - Main Menu window, click System Configuration. 3 Click System-wide. 4 Clear all Auto Discover check boxes. 5 Click Apply. 6 Click OK to close the dialog box.

You can configure the NBX system to behave in one of the three traditional telephone system modes:

■ Key mode – CO lines map to buttons on users’ telephones

To configure key mode behavior using the NBX NetSet utility, use Button Mappings and the Auto Extension setting for each line card port. Button Mappings enable you to map a line card port extension to a specific Access button on a 3Com telephone. Button Mappings identify the telephones that ring when a call comes in on the mapped CO line. Auto Extension specifies the destination of a call that is not answered at any of the telephones.

■ PBX mode – CO lines are pooled and arbitrated by the NCP

The CO lines do not map to individual telephones. All incoming calls go first to a receptionist’s telephone or the Automated Attendant. If the call goes to a receptionist’s telephone, the receptionist forwards the call to the user’s extension, or if the user is out of the office, the call can be sent directly to the user’s voice mailbox. To call an outside number, a user must dial the line pool access number, typically 9, and the NCP assigns the next available line. PBX mode allows you to make maximum use of a limited number of CO lines.

Direct Inward Dialing (DID) configuration requires changes to the system dial plan. For more information on DID, see the NBX Administrator’s Guide.

Using Auto Discover for Initial System Configuration 97

■ Hybrid mode – Combines key mode and PBX mode

Some CO lines are mapped directly to telephones, while the rest are pooled.

PBX mode is the easiest configuration to set up and manage. Key mode requires more configuration because you must map the CO lines to telephones.

Reassigning

Extensions and

Setting Line Card Port

Options

For this procedure, you need the list of line card port MAC addresses that were created when you installed the line cards.

To reassign extensions and set line card port options:

1 Log in to the NBX NetSet utility using the administrator username and

password.

2 In the NBX NetSet - Main Menu window, click Device Configuration. 3 Click the Line Card Ports tab. 4 Select the port with the lowest extension. 5 Click Modify. The Modify Line Card Port dialog box appears. 6 Edit the line card port fields as needed. The the Help for information

about each field.

7 After you have made all of your changes for the current Line Card port,

click Apply to enable the changes and review them.

8 Click OK to exit the dialog box and return to the Line Card Ports tab. 9 Repeat this procedure for each line card port.

Example:

During the Auto Discover process, the NBX system may assign extensions to Line Card ports as shown in

Ta bl e 20.

98 CHAPTER 2: INSTALLING SYSTEM HARDWARE COMPONENTS

Typically, you want to have the lowest extension number associated with the first port, the next highest extension number associated with the second port, and so on.

To reassign the extension numbers:

1 Record the extensions and either the MAC addresses or port numbers for

the four Line Card ports.

2 In the NBX NetSet – Main Menu window, click Reports. 3 Click the Device List tab. 4 Review the extensions in the scroll list to find the highest extension

number that has been assigned. Add one to that extension and record it. For example, if the highest assigned extension number is 7268, you record 7269.

5 Return to the Line Cards tab. 6 From the four Line Card ports you recorded, select the port with highest

MAC address or port number and click Modify.

7 In the Modify Line Card Port dialog box, change the extension number

(7258 in this example) to the extension number you recorded when you were viewing the Device List tab (7269).

8 Click OK. The Line Card Ports tab reappears showing the new extension

number. Extension 7258 is now unused.

9 From the four Line Card Ports you recorded, select the port to which you

want to assign the unused extension. In the example, 7258 is the lowest extension number of the four, so select the port with the lowest MAC address or port number and click Modify.

10 Change the extension number and click OK.

Repeat steps 9 and 10. Each time that you assign an extension, the previous extension is no longer used, and you can assign it to the appropriate port. When you are finished:

■ The four original extensions (7258 through 7261) are assigned to the

line card ports in the same order as the MAC addresses or port numbers.

■ The unused extension (7269) is again unused.

Connecting Telephone Lines 99

Connecting Telephone Lines

Adding External Hardware

Connecting a

Music-on-Hold (MOH)

Input Device

After you have installed and configured the system for initial startup, connect the telephone company lines to the analog line ports so that you can start receiving outside calls.

External devices connect to the front of the NBX system. See “What

External Devices Can Connect to an NBX System?” on page 64.

Use a patch cord with phono-type connectors (stereo or mono) to connect line level audio from any audio device that has a line-out jack to the MOH jack on the front of the NCP. The audio input should be max 2V peak to peak.

Adjusting Music-on-Hold (MOH) Volume

The NBX 100 and SuperStack 3 NBX have an external control for adjusting the MOH volume. For an NBX V3000 system, use the volume control on the external MOH device.

To adjust the volume of music on hold on an NBX 100 or SuperStack 3 NBX:

1 Use a nonferrous (plastic or aluminum) adjustment tool to adjust the

volume control on the front of the Call Processor to about mid-range.

Connecting a Paging

Amplifier

2 Use a 3Com Telephone to call another extension, and have the person

put you on hold.

3 While listening to the music, adjust the volume control on the

music-on-hold input device.

Connect the paging device to the paging connector on the front of the NCP. See the documentation for your paging amplifier for information about that device. For information about how to page from a telephone on the NBX system, see “Paging” in the NBX Telephone Guide.

The paging connector on the NCP is an RJ-11 connector. It is a line-out, 600 ohm audio interface with a dry contact closure for use with an external paging amplifier (

Configuring Routing Devices

If you have a low-bandwidth device on the LAN, such as an ISDN router, you must update the device’s routing table to filter NBX system multicast addresses. The NBX system uses Ethernet multicast addresses to implement some system features.

If you have telephones connected to the network through a low-bandwidth link, such as an ISDN connection, you can configure them so that they do not generate multicast traffic (

Ta bl e 22). For more

information, see the NBX Administrator’s Guide. You must still filter multicasts to ensure that multicasts generated by other NBX devices are not propagated through the low-bandwidth link.
