Installation Safety warning

Only qualified persons should service this system.

The installation and service of this hardware is to be performed only by service personnel having appropriate training and experience necessary to be aware of hazards to which they are exposed in performing a task and of measures to minimize the danger to themselves or other persons.

Electrical shock hazards from the telecommunication network and AC mains are possible with this equipment. To minimize risk to service personnel and users, the system must be connected to an outlet with a third-wire ground.

Service personnel must be alert to the possibility of high leakage currents becoming available on metal system surfaces during power line fault events near network lines. These leakage currents normally safely flow to Protective Earth ground via the power cord.

Therefore, it is mandatory that connection to an earthed outlet is performed first and removed last when cabling the unit. Specifically, operations requiring the unit to be powered down must have the network connections (central office lines) removed first.

This equipment meets all applicable requirements of CSA and UL safety standards for North America and relevant EN60950 specifications for European and other markets.

What’s new with Norstar

The Norstar Compact ICS 6.1 software includes several new features and a few functionality changes.

New features for version 6.1

• Key Indicator Module (KIM) and T7316E Business Series Terminal (BST) create a Central Answering Position (CAP).

These two pieces of hardware are designed to replace the M7324/CAP setup. The T7316E can also be deployed as a stand-alone unit, and works the same way as previous versions of the T7316 with some minor changes, including an active handsfree key below the main dialpad. (CAP/KIM assgn on page 225)

The KIM can be used in two configurations. The ordinary KIM (OKIM) has the same functionality as the current unassigned CAP module. The enhanced KIM (eKIM) supports multiple lines, including target lines, and hunt group appearances.

Up to four KIMs can be attached to a T7316E, without requiring a supplementary power supply. A T7316E can only support a maximum of four eKIMs, however, it can support up to nine OKIMs, with the addition of a station auxiliary power supply (SAPS). The system can support one CAP with an eKIM. This number will include any T7324based CAP installations you might already have. The system can support any number of CAPS using OKIMs.

T7316E telephones and KIMs also provide call-specific icons to make call tracking easier.

You cannot program Answer DNs onto a KIM.

• destination code enhancements

— 12-digit destination code: You can specify up to 12 digits as a

destination code, which allows you to support user expectations of dialing requirements for existing systems. For instance, if your users are used to dialing 91XXX-XXX-XXXX for a long distant call, they can continue to do so, so you can provide a seamless transition to network dialing. (Dest codes on page 181)

— multiple least-cost routing: When you specify a schedule other

than Normal for a destination code, you can specify up to three

possible routes the call can access, in order of preference. The system tries the first route, and if that route is not available, the system moves to the next route, and so on. (Multiple least cost routing on page 189)

• Silent monitor for hunt groups

Your Hunt group supervisors can now monitor hunt group calls, either silently, or by providing a conference tone to indicate that the call is being monitored (Monitoring Hunt groups on page 210). Other new functionality has been added to allow you to determine which telephones will be allowed to silent monitor (Capabilities on page

148), how many monitoring telephones your system will allow (SM sets on page 248), and what password is required to enter a monitoring session (Silent Monitor password on page 201). Refer to the Modular ICS 6.1 System Coordinator Guide for a detailed description about how to use the feature.

Welcome to ISDN

This chapter provides you with some background information about ISDN and also includes information about:

• Analog vs. ISDN

• Type of ISDN service

• ISDN layers

• ISDN Bearer capability

• Services and features for ISDN BRI

• ISDN hardware

• ISDN standards compatibility

Integrated Services Digital Network (ISDN) technology provides a fast, accurate and reliable means of sending and receiving voice, data, images, text, and other information through the telecom network.

ISDN uses existing analog telephone wires and divides them into separate digital channels, which dramatically increases the bandwidth.

ISDN uses a single transport to carry multiple information types. What once required separate networks for voice, data, images, or video conferencing is now combined onto one common high-speed transport.

Note: Nortel endeavours to test all variations of ISDN BRI and PRI on

Norstar. However, due to the number of variations, this is not always possible. Check with your service provider about compatibility.

Comparing ISDN to Analog

ISDN offers significantly higher bandwidth and speed than analog transmission because of its end-to-end digital connectivity on all transmission circuits. Being digital allows ISDN lines to provide better quality signaling than analog POTS lines and ISDN out-of band data channel signaling offers faster call set up and tear down.

While an analog line carries only a single transmission at a time, an ISDN line can carry one or more voice, data, fax and video transmissions simultaneously.

P0603539 02 Compact ICS 6.1 Installer Guide

28 / Welcome to ISDN

An analog modem operating at 14.4 K takes about 4.5 minutes to transfer a 1 MB data file and a 28.8 K modem takes about half that time. Using one channel of an ISDN line, the transfer time is reduced to only one minute. If two ISDN channels are used, transfer time is just 30 seconds.

When transmitting data, the connect time for an average ISDN call is about three seconds per call, compared to about 21 seconds for the average analog modem call.

BRI ISDN service

Basic Rate Interface (BRI) ISDN service provides lines where each line is made up of separate channels known as B and D channels which transmit information simultaneously.

BRI is known as “2B+D” because it consists of two B-channels and one D-channel.

B channels

B channels are the bearer channel and are used to carry voice or data information and have speeds of 64 kbps. Since each ISDN line (BRI) has more than one B-channel, a user can perform more than one transmission at the same time using a single ISDN line.

D channels

The standard signaling protocol is transmitted over a dedicated data channel called the D-channel. The D-channel carries call setup and feature activation information to the destination and has speeds of 16 kbps. Data information consists of control and signal information and packet-switched data such as credit card verification.

Welcome to ISDN / 29

ISDN layers

ISDN layers refer to the standards established to guide the manufacturers of ISDN equipment. The layers include both physical connections, such as wiring and logical connections, which are programmed in computer software.

When equipment is designed to the ISDN standard for one of the layers, it works with equipment for the layers above and below it.

There are three layers at work in ISDN for Norstar. To support ISDN service, all three layers must be working properly.

• Layer 1: A physical connection that supports fundamental signaling passed between the ISDN network (your service provider) and the Norstar Compact ICS. When the BRI card LED for a loop which is used for a network connection is lit, layer 1 is functioning.

• Layer 2: A logical connection between the ISDN network (your service provider) and the Norstar Compact ICS. Norstar has two of these connections for each BRI line, one for each of the logical lines. Without Layer 2, call processing is not possible and there is no dial tone.

• Layer 3: Also a logical connection between the ISDN network (your service provider) and the Norstar Compact ICS. For BRI lines, layer 3 is where call processing and service profile identifier (SPID) information is exchanged. This controls which central office services are available to the connection. For example, a network connection can be programmed to carry data calls.

The system of layers is important when you are installing, maintaining, and troubleshooting an ISDN system. See Problems with BRI service on page 288 for more information about working with the layers.

ISDN Bearer capability

Bearer capability describes the transmission standard used by the BRI line so that it can work within a larger ISDN hardware and software network.

The bearer capability for BRI is voice/speech, 3.1 kHz audio, and data (unrestricted 64 kbps, restricted 64 kbps, 56 kbps).

Services and features for ISDN BRI

As part of an ISDN digital network, your Compact ICS supports enhanced capabilities and features, including:

• faster call set up and tear down

• high quality voice transmission

• dial-up Internet and local area network (LAN) access

• video transmission

• network name display

• name and number blocking (BRI and analog)

• access to public protocols (NI-1 for BRI)

BRI services and features

• data transmission at speeds up to 128 kbps per loop (depending on the bandwidth supported by your service provider)

• shared digital lines for voice and data ISDN terminal equipment

Norstar Basic Rate Interface (BRI) cards also support D-channel packet service between a network and terminal connection. This allows you to add applications, such as point-of-sale terminals, without additional network connections.

Any analog or digital network connections can be shared by all Norstar telephones, peripherals and applications, and ISDN terminal equipment (TE).

Compact ICS supports the following ISDN services and features offered by ISDN service providers:

• D-channel packet service to support devices such as transaction terminals. Transaction terminals are used to “swipe” credit or debit cards and transmit the information to a financial institution in data packets.

• calling number identification (appears on both Norstar sets and ISDN terminal equipment with the capability to show the information)

• Multi-Line Hunt or DN Hunting, which switches a call to another ISDN line if the line usually used by the Network DN is busy.

Compact ICS 6.1 Installer Guide P0603539 02

Welcome to ISDN / 31

• subaddressing of terminal equipment (TE) on the same BRI loop. However, terminal equipment which supports sub-addressing is not commonly available in North America.

Transmission of B-channel packet data is not supported by Compac tICS.

Contact your ISDN service provider for more information about these services and features. Packages for ISDN service in North America are described on page 38.

The terminal equipment (TE) connected to the Norstar system can use some feature codes supported by the ISDN service provider. See ISDN services and features in the Compact ICS 6.1 System Coordinator Guide for more information.

Network name display

When your phone rings, this feature allows you to see the name of the person who is calling you. This call information is only available from the public network and must be activated on the public network side of the switch.

Name and number blocking

This feature allows you to program a feature button with the code from the CO that is used to suppress the outgoing name and/or number for your telephone. For information about system programming of this feature, see Outgoing Name and Number Blocking on page 253.

MCID (ETSI system feature)

The MCID feature allows you to use information recorded on the central office database for an incoming call on a specific line (EUROISDN lines, only).

The user must invoke the feature code without hanging up, and within 30 seconds (time varies on different networks) after the caller hangs up.

Network Call Diversion (ETSI system feature)

This feature is a network function of ETSI E1 lines that allows forwarding and redirection of calls outside the Norstar network when using an ETSI ISDN line. Functionality is similar to that of External Call Forward (ECF). NCD redirects calls using the same line on which they arrive. Call forward is efficient since there is no need for additional outside lines.

ISDN hardware

To support connections to an ISDN network and ISDN terminal equipment, your Compact ICS must be equipped with one or more BRI Cards (BRI-U or BRI-ST).

BRI Card

The loops on BRI-U and BRI-ST Cards can be programmed to support either network or terminal connections. This allows you to customize your arrangement of lines, voice terminals, data terminals and other ISDN equipment. This section describes some basic hardware configurations for network and terminal connections for each loop type.

For detailed wiring information about BRI network and terminal connections see Installation on page 69.

BRI-U2 and BRI-U4

A BRI-U2 Card supports two loops and the BRI-U4 supports four loops. Each loop can be individually programmed to provide one of the following:

• a U-LT reference point connection for terminal equipment (TE) with built-in NT1 functionality (U interface)

• a U-NT reference point connection for direct connection to an ISDN network

BRI-ST Card

A BRI-ST Card provides four loops. Each loop can be individually programmed as one of the following:

• an S reference point connection (S loop) to ISDN TE

• a T or S reference point connection (T loop or S loop) to an ISDN

network using an external NT1

Welcome to ISDN / 33

U-LT reference point

The U-LT reference point connection provides a point-to-point digital connection between Norstar and TE equipped with a U interface.

A U-LT loop supports up to eight ISDN DNs, which identify TE to the ICS.

To deliver D-packet service, a network connection (U-NT) is programmed to work with a terminal connection (U-LT). The loops must be on the same physical card. For example, if the network connection is a loop found on the BRI Card in Slot 1, the terminal connection must be a loop found on the same card.

S reference point

The S reference point connection provides a point-to-point digital connection between Norstar and ISDN terminal equipment (TE) that uses an S interface.

S loops support up to seven ISDN DNs, which identify TE to the ICS.

A T loop can be used in combination with an S loop to provide D-packet service for a point-of-sale terminal adapter (POSTA) or other D-packet device. D-packet service is a 16 kbps data transmission service that uses the D-channel of an ISDN line.

To deliver D-packet service, a network connection (T loop) is programmed to work with a terminal connection (S loop). The loops must be on the same physical card. For example, if the network connection is a loop found on the BRI Card in Slot 1, the terminal connection must be a loop found on the same card

Clock Source for ISDN Cards

Systems with ISDN interfaces need to synchronize clocking with the ISDN network and any connected ISDN terminal equipment. Clocking synchronization is supported by a Services Cartridge.

The Compact ICS derives timing from the network using U-NT and T reference points (loops). Terminal equipment on U-LT and S reference points (loops) derive timing from the ICS.

P0603539 02 Compact ICS 6.1 Installer Guide

36 / Welcome to ISDN

Systems synchronize clocking to the first available, functional, network connection. If there are excessive errors on the reference network connection, or the loop fails, the next available, functional, network connection is used for clock synchronization.

When you configure the network connections to the Compact ICS, you should take into account the system preferences for selecting loops for synchronization:

• lower numbered loops have preference over higher numbered loops

• the loop preference order is: 201, 202, 203, 204, 231, 232, 233, 234

• the system skips U-LT, S, and analog loops when selecting a network

connection for synchronization

Systems with only U-LT and S loops act as timing masters for the attached terminal equipment (TE), and are not synchronized to the network. ISDN TE without access to a network connection (BRI lines) has limited or no functionality.

Other ISDN BRI equipment

NT1

The NT1 (network termination type 1) connects an S interface (four-wire) to a U interface (two-wire). In most cases, it connects loops from a BRI-ST card to the network connection, which uses the U interface. It can also connect S interface terminal equipment (TE) to the U loop from a BRI-U2 or BRI-U4 card.

An NT1 is not required to connect from the network to BRI-U cards or to connect U interface TE to an ICS equipped with BRI-U cards.

The NT1 converts and reformats data so it can be transmitted to and from the S or T connection. In addition, it manages the maintenance messages travelling between the network and the NT1, and between the NT1 and the ICS.

The NT1 from Nortel Networks is packaged two ways:

• a stand-alone package which contains one NT1 card (NTBX80XX) and a power supply (NTBX81XX)

• a compact package which contains up to 12 NT1 cards (NTBX83XX) and a power supply (NTBX86AA)

ISDN standards compatibility

Norstar ISDN equipment supports National ISDN standards for basic call and calling line identification services.

Norstar BRI is compliant with National-1.

Planning your ISDN network

Consult ISDN hardware on page 32 and ISDN programming on page 39 to determine a configuration of ISDN trunks and terminal equipment (TE) for the Compact ICS, then order the appropriate ISDN capability package from your ISDN service provider.

For ISDN BRI service your service provider supplies service profile identifiers (SPIDs), network directory numbers (Network DNs), terminal endpoint identifiers (TEIs), and other information that is required to program your Compact ICS, TE and other ISDN equipment.

Compact ICS does not support any package with EKTS (Electronic Key Telephone System), CACH (Call Appearance Call Handling), or Calling Name Display. EKTS is a package of features provided by the service provider and may include features such as Call Forwarding, Link, Three-Way Calling, and Calling Party Identification.

Ordering ISDN BRI

Ordering service in Canada

In Canada, order Microlink™ service, the trade name for standard BRI service. You can order either regular Microlink™ service, which includes the CLID (Calling Line Identification) feature, or Centrex Microlink™, which includes access to additional ISDN network features (including Call Forwarding).

When ordering Microlink™ service, it must be ordered with EKTS (Electronic Key Telephone System) turned off. If you will be using a pointof-sale terminal adapter (POSTA), ask for D-packet service to be enabled.

If you are setting up a D-packet service, program the point-of-sale terminal adapter or other D-packet service device with the appropriate TEI (provided by your service provider), terminal SPID, and DN by following the instructions that come with the device.

Programming ISDN BRI lines

When the configuration programming under

Hardware

is complete, your BRI lines are ready to be programmed in the same way as analog lines. You can, for example, place them in pools and assign them to Norstar or Business Series Terminals (BST) telephones and ISDN terminal equipment. However, there are some differences in the way BRI lines work that will influence how you configure them to handle incoming and outgoing calls.

For BRI lines, in most cases, your service provider supplies two SPIDs, one for each B channel. Each SPID and one or more Network DNs are associated with a single line. Calls to a Network DN come in on a specific line, and pressing a line button selects the same line every time.

If your service provider supplies you with a single SPID for both B channels, incoming and outgoing calls are handled according to the loop. The two lines provided by the BRI loop are pooled for both incoming and outgoing calls.

For example, if Loop 201is programmed with a single SPID, which supports lines 001 and 002, incoming calls made to a Network DN associated with the SPID appear on either line 001 or line 002. If you press the line button for line 001, either line 001 or line 002 is selected. For loops

which use a single SPID, assign both lines on a loop to a telephone to guarantee that all calls appear at the telephone.

Programming ISDN equipment

Terminal equipment for BRI cards

Unlike Norstar or BST telephones, ISDN devices and terminals connected to the ICS must be configured under the programming. You choose directory numbers for ISDN equipment from a pre-determined range of DNs (273-304). Any of the ISDN DNs can be assigned to any U-LT or S loop, but each can only be assigned to one loop and a single device.

Hardware

Devices on an S or LT loop (BRI cards only)

Terminal equipment using a U-LT loop or S loop must be assigned an ISDN directory number (ISDN DN). This allows you to assign lines to the terminal equipment and allows the TE to communicate with other devices connected to the ICS. Each DN can be assigned only to one TE and to one loop.

heading in system

You assign ISDN DNs to S loops and LT loops under

Hardware

ISDN DNs, but you cannot exceed a total of 30 ISDN DNs for the Compact ICS.

Once you have assigned ISDN DNs to a loop, designate one of the DNs as a Loop DN. The Loop DN acts as a main ISDN DN and completes the configuration of the loop.

The ISDN terminal equipment (TE) on the loop is also programmed with its ISDN DN. See the instructions that come with the ISDN device for information about how to program it to recognize its assigned DN. Most devices will require both a terminal service profile identifier (terminal SPID) and a DN. Some will require two terminal SPIDs and two ISDN DNs. The SPID used with the device should not be confused with a SPID used for network connections using an T or NT loop.

To create a terminal SPID for a device, add at least two zeros to the end of the of the ISDN DN. Add more zeros to the beginning or end of the ISDN

To support Internet access, you must order BRI lines from your service provider, and subscribe to Internet service from an Internet service provider (ISP). Your computers must have an Internet browser and any applications supplied by your ISP.

D-packet service (BRI cards only)

The D-packet service supplied by the Compac tICS supports a point-ofsale terminal adapter (POSTA). Connecting a POSTA allows transaction terminals (devices where you swipe credit or debit cards) to transmit information using the D channel of the BRI line, while the B channels of the BRI line remain available for voice and data calls. A special adapter links transaction equipment (such as cash registers, credit card verification rigs, and point-of-sale terminals) to the X.25 network, a data communications network designed to transmit information in the form of small data packets.

LAN

To support the D-packet service, your ISDN network and financial institution must be equipped with a D-packet handler. To convert the protocol used by the transaction equipment to the X.25 protocol, your

ISDN network must also be equipped with an integrated X.25 PAD which works with the following versions of X.25: Datapac 32011, CCITT, T3POS, ITT and API. The ISDN service package you order must include D-packet service (for example, Package P in the U.S.; Microlink™ with D-channel in Canada).

Your service provider supplies a Terminal Endpoint Identifier (TEI) and DN to support D-packet service. The TEI is a number between 00 and 63 (in Canada, the default range is 21-63). Your service provider may also supply you with a DN to program your D-packet device. The DN for D-packet service becomes part of the dialing string used by the D-packet to call the packet handler.

POSTA for ISDN BRI

When you configure D-channel packet service, you are specifying the transmission path between an ISDN loop on the network side of the ICS and the ISDN loop on the set side (the loop used by the point-of-sale terminal adapter). The service is turned on and configured using the network loop programming found under and BRI-U4 Cards; S or T loop for BRI-ST Cards).

The point-of-sale terminal adapter is an analog device that connects to point-of-sale devices using an RS-232 interface and a U-LT loop. It handles the routing of packet information from the devices to the ICS and into the ISDN network.

Your service provider (usually a financial institution) supplies you with information about the compatible controller, which handles the routing of packet information from the devices to the ICS and into the ISDN network.

Trunks are external lines that provide the physical connection between a Norstar system and other systems in a private or public network. Norstar Compact ICS supports two different types of trunks:

• Loop start trunks handle incoming and outgoing calls between Norstar and the public network. They are numbered 001-004 and 031-034.

• BRI trunks handle incoming and outgoing calls between Norstar and an ISDN network. They are numbered from 001-008 and 031-038.

Target lines are virtual communication paths between trunks and telephones on the Norstar system. They are incoming lines only, and cannot be selected for outgoing calls. You can use target lines to simulate direct inward dialing (DID) service by routing calls to telephones according to the digits received from the central office on a BRI trunk.

Target lines are numbered 061 to 086. Telephones can be configured to have an appearance of any type of trunk and line (including target lines).

Loop start trunks

Loop start trunks provide incoming and outgoing access to the public network. Loop start trunks can be configured as manual-answer or auto-answer. The answer mode determines how the system handles incoming calls.

When a call comes in on a manual-answer loop start trunk, it alerts at all telephones with that line appearance.

When a call comes in on an auto-answer loop start trunk that is configured to answer with direct inward system access (DISA), the caller hears a stuttered dial tone. They must enter a six-digit Class of Service (COS) password from a dual tone multifrequency (DTMF) telephone to access system dial tone. Once the caller has system dial tone, they can then enter a target line number, a line pool access code or a remote feature code.

By default, auto answer loop start trunks are configured to answer with DISA, and are used to provide controlled access to Norstar system resources.

Compact ICS 6.1 Installer Guide P0603539 02

Trunks and target lines / 49

When a call comes in on an auto-answer loop start trunk that is not configured to answer with DISA, the caller hears system dial tone. They can then enter:

• a target line number

• a DISA DN, which is the number that will prompt for a COS password

• a line pool access code

• a remote feature code from a DTMF telephone

To place an outgoing call, a loop start line can be selected by pressing a line button on the telephone, by dialing a line pool access code, or by pressing a memory button that has been programmed with a line pool access code.

Tip -

Loop start signaling is supported by Loop Start /

Disconnect Supervision (LS/DS) Analog Trunk Cartridges and Call Information (CI) Trunk Cartridges. Each LS/DS Analog Trunk Cartridge or CI Trunk Cartridge can provide four loop start trunks. To configure the loop start trunks as auto-answer, the trunks must have disconnect supervision enabled. The central office must provide far end disconnect supervision.

The default programming for trunks uses disconnect supervision. If the central office does not provide far end disconnect supervision, the Trunk Mode setting in Lines programming should be changed to unsupervised.

You may configure a loop start trunk as the prime line for a Norstar telephone. The prime line is the line the telephone uses automatically if no other line is chosen or no line pool is entered.

The capabilities available to a remote caller are determined by the remote restrictions and remote package assigned to a line, or by the set restrictions, line restrictions and remote package assigned to the COS password.

Callers can also access the system by using the Auto Attendant features. See the Compact ICS Coordinator Guide for more information.

BRI trunks

BRI trunks give you incoming and outgoing access to an ISDN network. Like loop start trunks, they can be configured as manual-answer or autoanswer. See the Loop start trunks information that starts on page 48 for information on setting the answer mode.

BRI trunks provide a fast, accurate and reliable means of sending and receiving data, images, text and voice information. Using BRI lines allows for faster transmission speeds and the addition of a variety of powerful business applications, including remote LAN access, video conferencing, file transfer and Internet access.

For more information see Welcome to ISDN on page 27.

Target lines

A target line is a specific communication path that is reached by means of digits received from an incoming BRI trunk. Target lines are used to answer incoming calls but cannot be used to make outgoing calls.

You can program auto-answer BRI trunks to map to target lines to provide for attendant bypass (calling directly to a department or individual) and line concentration (one trunk can map onto several target lines).

No target lines are assigned to sets by default.

Target lines are referred to by line numbers (061-086) in the same way as physical lines.

Privacy issue

You can set a target line to Private (default is Public), however, such features as Call Pickup can still answer these lines from other system telephones.

Compact ICS 6.1 Installer Guide P0603539 02

Remote system access / 51

Remote system access

The remote access feature allows callers elsewhere on the public network to access a Norstar system directly without going through an attendant. Once in the system, the remote user can use some of the system resources. The remote access must be enabled in programming before callers can use it.

Norstar Compact ICS systems support remote system access on autoanswer loop start trunks and can require the remote caller to enter a (COS) password for direct inward system access (DISA).

The system resources —dialing capabilities, line pool access and feature access — that a remote user may access depends on the Class of Service (COS) assigned to them. See the description of COS on page 52 for more details.

To use features on a Norstar system remotely, press feature code. Even if you are calling from another Norstar system, press instead of

Remote access on loop start trunks

Loop start trunks provide remote access to the Norstar system from the public network and must be configured as auto-answer in Lines programming to provide remote system access.

A loop start trunk must have disconnect supervision enabled if it is to operate in auto-answer mode.

When a caller dials into the system on a line that has auto-answer, the system answers with system dial tone and no COS password is required. In this case, control over the system capabilities available to the caller is provided only by the restriction filters assigned to the line.

When a caller dials in on a line that has auto-answer with DISA, the system answers with stuttered dial tone. This is the prompt to the caller to enter a COS password, which determines which system capabilities are available to the caller.

Security

Programming provides several ways of protecting your Norstar system from unauthorized access or use.

Class of Service

Class of Service (COS) refers to the capabilities that Norstar provides to users who access the system from the public or a private network. The COS includes:

• filters that restrict dialing on the line

• an access package, which defines the set of line pools that may be

accessed and whether or not the user has access to the paging feature.

The COS that is applied to an incoming remote access call is determined by:

• the filters that you apply to the incoming trunk

• the COS password that the caller used to gain access to the Norstar

system.

In cases where DISA is not automatically applied to incoming calls, the remote caller can change the COS by dialing the DISA DN and entering a COS password.

To program COS passwords, see COS pswds on page 196 in this guide.

Restriction filters

Restriction filters can be used to restrict the numbers that may be dialed on any external line within the Norstar system. Up to 100 restriction filters can be created for the system. A restriction filter consists of up to 48 restrictions and their associated overrides.

Compact ICS 6.1 Installer Guide P0603539 02

Networking features / 53

To restrict dialing within the system, you can apply restriction filters to:

• outgoing external lines (as line restrictions)

• telephones (as set restrictions)

• external lines on specific telephones (as line/set restrictions)

Restriction filters can also be specified in Restrictions service for times when the system is operating according to a schedule. Refer to the description in Services on page 174 for more details.

For restriction filter programming instructions, see Restrn filters on page 170 in this guide.

Direct inward system access (DISA)

To control access from the public network, configure auto-answer trunks to answer with DISA. Remote callers hear a stuttered dial tone and must then enter a COS password that determines what they are allowed to do in the system.

Auto-answer loop start trunks are configured to answer with DISA by default. For DISA programming instructions, see Trunk/Line data under Lines on page 161 in this guide.

Transparent dialing plan

The Norstar system has a routing feature that allows you to set up a transparent or coordinated dialing plan with other systems in the public network. The goal is to have a network-wide dialing plan where all telephone numbers are unique and of a uniform length.

Dialing plans are typically used with a network of systems with a three to seven-digit dialing access between them.

Any programming for routing should be carefully planned using the tables supplied with the Programming Record. The settings for routing and destination codes are fully explained under Routing service on page 179. This section deals with applying the programming in network situations.

Dialing plan using public lines

The following illustrations show the Programming Record for a Toronto system in a network of three offices: Toronto, Halifax and Vancouver. Without routing, a Norstar user in Toronto would have to select a line pool and dial 1-902-585-3027 to reach extension 27 in Halifax (902). By creating a destination code of 30 and creating a route that uses the proper line pool and DialOut, the user simply dials 3027. The same feature is available for Vancouver (604).

In the DialOut, P stands for pause, a host system signaling option. Press

²à¡

to insert a 1.5-second pause in the dialing string. See the System

Coordinator Guide for information about other signals.

ISDN terminal equipment delivers a wide range of powerful business applications:

Video conferencing and video telephony

Video conferencing offers instant visual and audio contact between distant parties using either studio-based or desktop ISDN terminals.

Desktop conferencing

ISDN allows computer users in distant locations to share and edit any image, data or text file on their own computer screens while they discuss the information.

File transfer

The ISDN network allows you to transfer files containing data, text, images, data, or audio clips, faster and cheaper than with a conventional modem.

P0603539 02 Compact ICS 6.1 Installer Guide

58 / Data Solutions

Telecommuting

Convenient retrieval, processing and storage of files is possible for the employee working at home by using ISDN lines to give high-speed access to information resources at the office.

Group 4 fax

ISDN fax applications save money by increasing both transmission speed and the quality of resolution.

Remote LAN access

ISDN provides an affordable and fast means for employees at remote sites, such as at home or in branch offices, to access local area networks (LANs).

Leased line backup

Essential backup for leased lines can be provided using ISDN as required, rather than duplicating costly permanent leased lines.

LAN to LAN bridging

Local area network (LAN) bridge/routers allow flexible interconnection between LANs using ISDN, with charges only incurred when information is actually transmitted.

Internet and database access

The fast call set up and high bandwidth of ISDN are ideal for accessing information services such as the Internet and databases.

Upgrading your system

Only qualified persons should service the system.

Electrical shock hazards from the telecommunication network and AC mains are possible with this equipment. To minimize risk to service personnel and users, the ICS must be connected to an outlet with a third-wire ground. In addition, all unused slots must have filler faceplates installed and the system cover must be locked in place at the completion of any servicing.

Service personnel must be alert to the possibility of high leakage currents becoming available on metal system surfaces during power line fault events near network lines. Risk points on the ICS are the Feature Cartridge, heatsink and power cord earth ground pin. These leakage currents normally safely flow to Protective Earth ground via the power cord. Therefore, it is mandatory that connection to an earthed outlet is performed first and removed last when cabling to the unit. Specifically, operations requiring the unit to be powered down must have the network connections (central office lines) removed first.

72 / Testing the ISDN network connection

Testing the ISDN network connection

Before you install a Norstar system which uses BRI Cards, you should test your connection to the ISDN network.

If you are installing a system which connects to the network using BRI-ST Cards, the network connection must be equipped with an NT1. See the ISDN chapter and the wiring information in this chapter for more information about installing an NT1.

To test the ISDN connection:

1. Connect ISDN terminal equipment (TE) that conforms to Bellcore standards to your central office ISDN jack or NT1. U interface TE can connect directly to the central office jack; S interface TE connect to the central office through an NT1.

2. Program the TE with the appropriate switch type, service profile identifier (SPID), and Network directory number (DN) using the instructions that come with the TE.

3. Check for dial tone, then place a call and verify the quality and clarity of the connection. If there is a problem, contact your service provider.

4. Repeat steps 1 through 3 for each network connection.

Terminating resistors on BRI-ST Cards

The standard ISDN user-network interface wiring requires terminating resistors at each end of the loop for both point-to-point and point-tomultipoint operation. This ensures correct timing of the signaling circuits.

Loop termination can be provided at either the point where the ISDN terminal is attached, or by the device attached to the loop (with built-in termination).

Because the Compact ICS is usually at the one end of the loop, the BRI-ST Card is shipped with built-in termination for each ISDN loop. It is ready to be used where the ICS is located at one end of the loop, as shown in the following illustration:

Installing Trunk Cartridges

1. Slide the Trunk Cartridge into slot 1, applying equal pressure at the top and bottom. See illustration on the next page.

2. Close the cartridge clips at the same time, to keep the cartridge aligned with the connector.

3. If you are installing a second trunk cartridge, remove the filler faceplate from slot 2 and slot 3 (it is one piece), using a screwdriver at the bottom of each slot and prying the bottom edge out.

4. Snap the two parts of the faceplate apart and put back the filler faceplate in slot 3.

5. Insert the second Trunk Cartridge, as described in steps 2 and 3.

Connecting the wiring to the distribution panel

1. Route the cables from the ICS to the distribution panel.

2. Bundle the cables with cable ties and secure them to the wall to support their weight.

3. Connect the telephone and auxiliary equipment wires to the appropriate pins on the distribution block (refer to the wiring charts).

4. Cross-connect the ICS telephone and auxiliary equipment wiring to the corresponding station pins on the distribution block.

5. Using a single pair of wires for each telephone, connect each of the telephones according to the wiring charts.

6. Cross-connect the external lines to the distribution block (refer to the wiring charts).

Wiring charts

Port numbering on the wiring charts

The port number listed on the wiring charts is useful in tracking down faults during a Maintenance session where error codes appear on a Norstar telephone display. Refer to Maintenance on page 305 for more information.

For example, the code 112 appearing as part of an error message indicates that the problem is with the telephone connected to the system at port 112. The corresponding pins on the distribution block are pin 37 (black-orange) and pin 12 (orange-black).

Integrated Communications System (ICS)

In the charts on the following pages, notice that the ICS has two 25-pair connectors. One handles telephones and auxiliary ringer. The other handles lines, I-ATA, music, and page.

B1 and B2 directory numbers (DNs)

Norstar has a B1 and B2 channel for transmitting voice and data. Each telephone port on the ICS has a B1 DN and a B2 DN. Devices such as the Business Series Terminals, and Norstar telephones use only the B1 DN. Other devices may need both B1 and B2 channels, therefore, requiring B1 and B2 DNs.

Norstar Compact ICS uses different numbering schemes for the B1 and B2 DNs, depending on how you upgrade your system and when an Expansion Cartridge is added. See the tables below for details.

BRI Wiring charts

A BRI Card in Slot 1 uses loops 201 through 204. A BRI Card in Slot 2 uses loops 225 through 228 (profile 1, 3 or 4) or loops 231 through 234 (profile 2). Because a BRI-U2 Card has only two loops, it only uses the first two loop numbers (201-202 and 225-226 (profile 1, 3, or 4) or 231-232 (profile 2)) when it occupies an ICS slot.

The loops appearing on a BRI Card may be automatically assigned lines, or assigned one or more ISDN DNs in

Wiring the BRI network interface

A network interface provides the connection between the ISDN network and the Compact ICS.

If the card in the ICS is configured as a T loop, the ICS is wired to the network connection using an NT1. For an S or T loop, the ICS and terminal equipment share the loop wired to the NT1, which is in turn wired to the network. See the ISDN chapter for more information about the NT1.
