Regulations

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.

P0603534 02 Modular ICS 6.1 Installer Guide

22 / Safety and installation

Safety and installation

The shock hazard symbol within an equilateral triangle is intended to alert personnel to electrical shock hazard or equipment damage.

The following precautions should also be observed when installing telephone equipment.

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

• Use caution when working with telephone lines.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

This symbol (if applicable) on the product is used to identify the following important information:

For equipment with internal power supplies

• Mains nominal AC voltage 110-120 V~; 60Hz

• Mains nominal AC voltage 220-240 V~; 50Hz

Modular ICS 6.1 Installer Guide P0603534 02

Safety and installation / 23

For equipment with external power supplies

• Must be powered from an approved Class 2 power source.

For current ratings, refer to product specific documentation and product labels.

Important safety instructions

When using your telephone equipment, basic safety precautions should always be followed to reduce the risk of fire, electric shock and injury of persons, including the following:

• Follow the warnings and instructions marked on the product.

• Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.

• Do not use this product near water, for example, near a bathtub, wash bowl, kitchen sink, or laundry tub, in a wet basement or near a swimming pool.

• Do not place this product on an unstable cart, stand or table. The product may fall, causing serious damage to the product.

• This product should never be placed near or over a radiator or heat register. This product should not be placed in a built-in installation unless proper ventilation is provided.

• Do not allow anything to rest on the power cord. Do not locate this product where the cord will be abused by persons walking on it.

• Do not overload wall outlets and extension cords as this can result in the risk of fire or electric shock.

• Never spill liquid of any kind on the product.

P0603534 02 Modular ICS 6.1 Installer Guide

24 / Safety and installation

• To reduce the risk of electric shock, do not disassemble this product, but have it sent to a qualified service person when service or repair work is required.

• Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following conditions:

a. When the power supply cord or plug is damaged or

frayed.

b. If the product has been exposed to rain, water or liquid

has been spilled on the product, disconnect and allow the product to dry out to see if still operates; but do not open up the product.

c. If the product housing has been damaged.

d. If the product exhibits a distinct change in performance.

• Avoid using telephone equipment during an electrical storm. There may be a remote risk of electric shock from lightning.

• Do not use the telephone equipment to report a gas leak in the vicinity of the leak.

• To eliminate the possibility of accidental damage to cords, plugs, jacks, and the telephone equipment, do not use sharp instruments during the assembly procedures.

• Do not insert the plug at the free end of the handset cord directly into a wall or baseboard jack. Such misuse can result in unsafe sound levels or possible damage to the handset.

• Disconnect telecommunications lines before unplugging main power cord.

• Save these instructions

What’s new with Norstar

The Norstar MICS 6.1 includes several new features and a few functionality changes.

To upgrade from any previous version of MICS software to MICS 6.1, refer to Upgrading your Norstar system on page 199 for detailed instructions.

New features and hardware for version 6.1

• T24 Key Indicator Module (KIM) and T7316E Business Series Terminal. When put together, the unit is referred to as a Central Answer Position (CAP).

These two pieces of hardware are designed to replace the M7324/CAP module 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. Both units come with installation instructions.

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 lines, multiple target lines, and hunt group appearances (CAP/KIM assign on page 435).

Up to four KIMs can be attached to an enhanced T7316E, without requiring a system auxiliary power supply (SAPS). A T7316E can only support a maximum of four eKIMs, however, it can support up to nine OKIMs, with the addition of a SAPS. The system can support a maximum of five CAP units using EKIMs. This number

P0603534 02 Modular ICS 6.1 Installer Guide

40 / What’s new with Norstar

will include any T7324-based CAP installations you might already have. The system can support many more CAP units using OKIMS.

The KIM and T7316E also provide call-specific icons to make call tracking easier.

You cannot program Answer DN keys 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, even though the call may go through your private network or may use more than one route. This allows you to provide a seamless transition to network dialing. (Routes and destination codes on page 381)

— 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. (Programming for least cost routing on page 395)

• 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 (Silent Monitor on page 432). Other new functionality has been added to allow you to determine which telephones will be allowed to silent monitor (Capabilities on page 335), how many monitoring telephones your system will allow (SM sets on page 466), and what password is required to enter a monitoring session (Silent Monitor password on page

407). Refer to the Modular ICS 6.1 System Coordinator

Modular ICS 6.1 Installer Guide P0603534 02

What’s new with Norstar / 41

Guide for a detailed description about how to use the feature.

• CLID display enhancements:

— display an incoming call CLID on a telephone with

activated CLID display, where a call is currently active.

• overlap dialing (profile 2 only)

— For calls over PRI lines that require pauses between

dialing sequences, this feature allows the line to send a dialtone to the user between dialing an access code and dialing the telephone number.

Other feature notes

• MCDN Meridian attendant break-in feature correction: Only post-dial break-in is allowed. (Break-in on page 154)

• MCDN Meridian attendant camp-on feature note: Meridian attendants need to be notified that they must wait at least five seconds before assuming that a camp-on call has been camped. This is due to remote system requirements for checking for busy on the target telephone and determining if a prime telephone has been assigned.

• MCDN on tandem networks has been adjusted to correct or accommodate some networking issues experienced in previous versions. Changes are invisible to the user.

The Norstar Remote Utility (NRU) application is being replaced by the ICS Remote Tools (ICSRT) application, which has some of the same functionality of Norstar Manager. The ICSRT Quick Reference Guide provides an overview of the features of the ICSRT application. The ICS Remote Tools User Guide provides details about using the application.

Welcome to ISDN

This chapter provides you with some background information about ISDN, including information about:

• analog vs. ISDN

• type of ISDN service

• ISDN layers

• ISDN bearer capability

• services and features for ISDN PRI and 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. The signal on the wire gets divided 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 on to one common high-speed transport.

Note: Nortel endeavors 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.

P0603534 02 Modular ICS 6.1 Installer Guide

44 / Welcome to ISDN

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 (plain ordinary telephone) lines. Also ISDN out-ofband data channel signaling offers faster call setup 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.

An analog modem operating at 14.4 K takes about 4.5 minutes to transfer a 1 MB data file, while a 28.8K 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.

Type of ISDN service

Two types of ISDN services (lines) are available: Basic Rate Interface (BRI) and Primary Rate Interface (PRI). 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 2 B-channels and one D-channel.

• PRI is known as 23B+D because it consists of 23 B-channels and one D-channel.

Modular ICS 6.1 Installer Guide P0603534 02

Welcome to ISDN / 45

B channels

B channels are the bearer channel. They are used to carry voice or data information and have speeds of 64 kbps. Since each ISDN line (BRI or PRI) has more than one B-channel, more than one transmission can occur 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. This channel has speeds of 16 kbps (BRI) and 64 kbps (PRI). Data information consists of control and signal information and packet-switched data such as credit card verification.

Tip -

channel only. Norstar does not include support for a backup D-channel on the span.

Norstar PRI supports the D-channel on the 24th

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.

P0603534 02 Modular ICS 6.1 Installer Guide

46 / Welcome to ISDN

Layer 1: A physical connection that supports fundamental signaling passed between the ISDN network (your service provider) and the Norstar ICS. When a DTI card configured as BRI or PRI is used for a network connection, the LED for the loop on the card is lit when the layer 1 is functioning.

Layer 2: A logical connection between the ISDN network (your service provider) and the Norstar 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 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 600 for more information about working with the layers.

ISDN bearer capability

Bearer capability describes the transmission standard used by the BRI or PRI line that allows it to work within a larger ISDN hardware and software network.

The bearer capability for BRI and PRI is voice/speech at

3.1 kHz audio, and data at unrestricted 64 kbps, restricted

64 kbps, 56 kbps.

• 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 pointof-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).

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

• D-channel packet service (BRI only) 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, which 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. (BRI only)

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

Modular ICS 6.1 Installer Guide P0603534 02

Welcome to ISDN / 49

Transmission of B-channel packet data is not supported by Modular ICS.

Contact your ISDN service provider for more information about these services and features. Packages for ISDN service in North America are described on page 64.

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

Feature descriptions

The following section provides brief descriptions about the ISDN features, and links for more programming information.

Network name display

This feature allows ISDN to deliver the Name information of the users to those who are involved in a call that is on a public or private network. For information about system programming for this feature see, BusName on page 453.

Systems with Advanced Private Networking connections (MCDN SL-1) to a Meridian system also retain information about sets that have forwarded or transferred a call, as well as the originating caller information.This feature is called Network Call Redirection Information (NCRI). This information is available to all parties involved in the call.

Calls can only be redirected for a defined number of times within the network. This is currently hardcoded to five times. Once this limit is reached, call redirection will be disallowed for any type of outgoing line being presented for redirection.

P0603534 02 Modular ICS 6.1 Installer Guide

50 / Welcome to ISDN

Instead, the call will be handled in one of these ways:

• If Call Forward on Busy is programmed, the call will ring if a free key is available. Otherwise, it goes to the Prime set. DND Busy programming is ignored.

• If Call Forward All Calls is programmed, the call will go to the Prime set.

• If Call Forward No Answer is programmed, the call will continue to ring at the destination.

Note: If a terminal rejects a call, the call goes to the Prime set,

if a Prime set is configured for the target line. If the target line is configured to send a busy tone, the call gets released with the reason as User Busy.

Message Waiting Indicator (MWI)

Systems with Advanced Private Networking connections to a Meridian system Voice Mail system provide message-waiting indicators at telephones connected to those lines. Telephones with displays display a message. Non-display terminals may have a lamp that lights when a message is waiting. The setting for this feature is defined from the Meridian system.

Name and number blocking

This feature suppresses the outgoing name and/or number on a call-by-call basis. For information on system programming of this feature see, Outgoing Name and Number Blocking on page 456.

External call forwarding

The system now allows you to forward calls to an external number. This feature is activated using ≤› from the telephone.

Modular ICS 6.1 Installer Guide P0603534 02

Welcome to ISDN / 51

MCDN trunk features

Systems with MCDN Private Networking connections can provide these trunk routing features:

• Trunk Route Optimization (TRO) finds the most direct route through the network to send a call between nodes. This function occurs during the initial alerting phase of a call.

• ISDN Call Connection Limitation: The ICCL feature piggybacks on the call initiation request and acts as a check at transit PBX points to prevent misconfigured routes or calls with errors from blocking channels.

• Trunk Anti-tromboning (TAT) is a call-reroute feature that works to find better routes during a transfer of an active call. This feature acts to prevent unnecessary tromboning of trunks. This action occurs after the speech path has been established.

Call by Call service selection for PRI

Call by Call service selection allows a user to access services or private facilities over a PRI line without the use of dedicated facilities. Various types of services such as FX, Tie, and OUTWATS are available, depending on the Protocol that is selected. Private network settings are used for tandem networking and Advanced Private Networking.

Outgoing calls are routed through a dedicated PRI Pool and the calls can be routed based on various schedules.

For information about system programming of this feature, see Programming Call by Call service selection on page 460.

Emergency 911 dialing

Modular ICS 6.1 with the ISDN PRI feature is capable of transmitting the telephone number and internal extension number of a calling station dialing 911 to the Public Switched Telephone Network.

State and local requirements for support of Emergency 911 dialing service by Customer Premises Equipment vary. Consult your local telecommunications service provider regarding compliance with applicable laws and regulations. For most installations, the following configuration rules should be followed, unless local regulations require other settings.

• All PSTN connections must be over PRI.

• In order for all sets to be reachable from the Public Safety Answering Point (PSAP), the system must be configured for DID access to all sets. In order to reduce confusion, the dial digits for each telephone should be configured to correspond to the extension number (DN).

• The OLI digits for each telephone should be identical to the DID dialed digits for the telephone.

• The routing table should route 911 to a public line or line pool.

• If attendant notification is required, the routing table must be set up for all 911 calls to use a dedicated line which has an appearance on the attendant console.

Note: The actual digit string 911 is not hard-coded into the

MCID (Profile 2)

The MCID feature allows you to use ≤°·‡ to have call 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 during the active call or within 30 seconds (time varies on different networks) after the caller hangs up. The user must remain on the line to enter the code.

Network Call Diversion (Profile 2)

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.

DTI card configured as a PRI card

The DTI card on your Norstar system can be configured to support PRI. For information about configuring a DTI card as a PRI type card, see Provisioning the DTI card for PRI on page

483.

ISDN hardware

To support connections to an ISDN network and ISDN terminal equipment, your Modular ICS must be equipped with one or more BRI cards (BRI-U or BRI-ST), a DTI card configured for PRI, and a Combination Fiber 6-port Services Cartridge or a Services Cartridge.

DTI card configured as PRI

A DTI card configured as PRI provides one T loop. Refer to T reference points on page 58 for more information.

In most PRI network configurations, you need one DTI card configured as PRI in your ICS to act as the primary clock reference. The only time when you may not have PRI designated as the primary clock reference is in a network where your Norstar system is connected back-to-back with another switch using a PRI link, such as is the case with the Advanced Private Networking configuration.

However, if the other switch is loop-timed to your Norstar system, your DTI card, configured as PRI, can be designated as a timing master.

If your Norstar has two DTI cards configured as PRI, you cannot assign both cards as the primary reference or both cards as the secondary reference. You can only have one primary reference and one secondary reference per system. Refer to ClockSrc on page 492 for more information.

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.

Detailed wiring information for BRI and PRI network and terminal connections is included in the Installation on page

219.

BRI-U2 and BRI-U4 card

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 to one of the following:

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

• a T or S reference point connection (T loop or S loop) to an ISDN network using an external NT1

U-LT reference point

The U-LT reference point connection provides a point-topoint 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. Refer to the example below.

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.

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 either a Combination Fiber 6-port Services Cartridge or a Services Cartridge.

The Modular 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.

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

The clock synchronization process generates alarm codes and event messages. See the Alarm codes on page 533 and Event messages on page 541 for more information.

When you configure the network connections to the Modular 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, 225, 226, 227, 228 (Profile 1, 3 and 4), or 201, 202, 203, 204, 231, 232, 233, 234 (Profile 2)

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

P0603534 02 Modular ICS 6.1 Installer Guide

60 / Welcome to ISDN

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.

If your system has both a BRI and a DTI card configured as PRI installed, it is recommended that you use PRI as the primary clock source, see DTI card configured as a PRI card on page 53.

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:

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

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

If you are setting up a D-packet service, program the pointof-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 PRI lines

When the configuration programming under Hardware is complete, your PRI lines are ready to be programmed. For information about programming your PRI lines, see Call by Call service selection for PRI on page 457.

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 telephones, Business Series Terminals, or 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. 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.

P0603534 02 Modular ICS 6.1 Installer Guide

72 / Working with ISDN

For example, if Loop 201 is 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 Direct Inward System Acce ss (DIS A) on PRI trunks

When a trunk cartridge is set to PRI, all lines on that trunk are set to Auto Answer without Direct Inward System Access (DISA).

DISA can be accessed by one of two methods.

1) Define the DISA DN to match the trailing digits of the Called Party Number (CDN).

With Public, Private, and Tie service types, the CDN is simply truncated to the Target Line Receive Digit Length and is parsed to match the Target Line Receive Digits. DISA can be accessed by having the DISA DN match the trailing digits of the CDN. For example, with a Receive Digit Length = 4, and DISA DN = 1234, a call made to Public DN 763-1234 will be handled as follows:

• the ISDN setup message will contain a CDN of 763-1234

• the CDN will be truncated to the four digits, 1234

• 1234 matches the DISA DN

• the call will be answered with DISA

2) Use incoming Call by Call (CbC) Service routing to map the

call type to the DISA DN. Refer to Programming Call by Call service selection on page 460 for more information.

Modular ICS 6.1 Installer Guide P0603534 02

Working with ISDN / 73

With FX, INWATS, 900, and SDS service types, either a Service Id (SID) or a CDN is mapped to Target Line Receive Digits.

This is programmed under Call-by-Call Routing. DISA may be accessed by having the SID or CDN map to the DISA DN. This example has a Receive Digit Length = 4, DISA DN = 1234, and CbC Routing with (Service Type = FX, Map from SID = 2, Map to digits = 1234).

A call presented to the Norstar system with service type FX and SID 2 will be handled as follows:

• The ISDN setup message will specify FX with SID = 2

• The FX SID = 2 will be mapped to DISA DN digits 1234

The call will be answered with DISA

Programming ISDN equipment

DTI cards configured as PRI support various applications that are enabled by PRI. For a list of the type of applications that are support, see ISDN applications on page 183.

Terminal equipment for BRI cards

ISDN devices and terminals connected to the ICS must be configured under the Hardware heading in system programming. You choose directory numbers for ISDN equipment from a pre-determined range of DNs (667-696). 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 one device.

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 the TE to be assigned lines and to communicate with other devices connected to the ICS. Each DN can be assigned to only one TE and one loop.

P0603534 02 Modular ICS 6.1 Installer Guide

74 / Working with ISDN

You assign ISDN DNs to S loops and LT loops under Assign DNs under Hardware. Each S or LT loop can be programmed

with eight ISDN DNs, but you cannot exceed a total of 30 ISDN DNs for the Modular 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 on how to program it to recognize the assigned DN. Most devices will require both a terminal service profile identifier (terminal SPID) and a DN, and 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 ISDN DN. Add more zeros to the beginning or end of the ISDN DN until you have the length of SPID required by the TE. For example, if an ISDN telephone requires a six-digit SPID and has a DN of 667, its SPID is

066700. If the same TE requires a minimum of 10 digits, the

SPID is 0000066700.

Most ISDN terminals require a five-digit SPID. An ISDN PC card usually requires a 10-digit SPID. Follow the directions that come with the ISDN device to program it with a SPID and ISDN DN.

To support Internet access, you must order BRI lines from your service provider, and subscribe to an Internet service from an Internet service provider (ISP). Your personal computer 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 Modular ICS supports a point-of-sale terminal adapter (POSTA). Connecting a POSTA allows transaction terminals, such as devices where you swipe credit or debit cards, to transmit information using the D channel of the BRI line. At the same time, 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. This is a data communications network designed to transmit information in the form of small data packets.

Modular ICS 6.1 Installer Guide P0603534 02

Working with ISDN / 77

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.

X.25 PAD 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. or Microlink™ with D-channel in Canada.

Your service provider supplies a Terminal Endpoint Identifier (TEI) and a DN to support D-packet service. The TEI is a number between 00 and 63 in the U.S. 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 telephone side. The telephone side loop is the loop used by the point-ofsale terminal adapter. The service is turned on and configured using the network loop programming found under Hardware. Use NT loop for BRI-U2 and BRI-U4 cards and S or T loop for BRI-ST cards.

To set up D-packet service:

• go to the programming settings for the network loop under

Hardware. (S, T, or NT loop)

• select the S loop or LT loop used by the POSTA

P0603534 02 Modular ICS 6.1 Installer Guide

78 / Working with ISDN

• enter the terminal endpoint identifiers (TEIs) supplied by

your service provider

Point-of-sale terminal adapter

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 and target lines

Trunks are external lines that provide the physical connection between a Norstar system and other systems in a private or public network. Trunks are numbered 001 to 156 in a fully expanded system. Norstar Modular ICS supports six different types of trunks:

• PRI trunks are used for incoming and outgoing calls over an ISDN network. PRI SL-1 lines can provide MCDN network functionality in a private network between other Norstar systems, Meridian 1 systems, or Business Communications Systems, if the appropriate software code has been installed.

• T1 trunks are digital trunks that can be configured to act as loop start, ground start, E&M, DID, or leased lines, depending on your requirements.

— DID trunks route incoming calls from the public

network directly to telephones within Norstar, without an attendant.

— Loop start trunks handle incoming and outgoing calls

between Norstar and the public network.

— E&M trunks handle incoming and outgoing traffic

between the Norstar system and the private network.

• BRI trunks handle incoming and outgoing calls between Norstar and an ISDN network.

• 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. With 192 target lines in a fully expanded system, you can concentrate auto answer calls on fewer trunks. This type of concentration is an advantage of target lines. Norstar mapping allows you to direct each target line to

one or more telephones. Target lines are numbered 157 to 348 in a fully expanded system, and 157 to 284 in all others.

Telephones can be configured to have an appearance of any type of trunk and line, including target lines, but excluding PRI trunks. If assigned, they are used for monitoring call usage.

Trunk operating modes (T1)

T1 trunks have four operating modes:

• ground start (T1 only)

• loopstart (analog and T1)

• E&M (analog and T1)

• DID (analog and T1)

Ground start trunks (T1 only)

Ground start trunks offer the same features as loop start trunks, but are used when the local service provider does not support disconnect supervision for the digital loop start trunks. Ground start trunks work with T1 only.

By configuring lines as ground start, the system will be able to recognize when a call is released at the far end.

Tips -

A DTI can provide a maximum of 24 ground start trunks. Analog ground start trunks are not supported.

82 / Trunks and target lines

When a call comes in on a DID trunk, the Norstar system interprets the incoming digits in one of the following ways.

• If the digits map onto a target line, the call is routed to all telephones with an appearance of that target line.

• If the digits map onto the DISA DN, the caller hears stuttered dial tone. They must enter a six-digit Class of Service (COS) password from a DTMF telephone to hear system dial tone.

They can then enter a:

— target line number

— line pool access code

— remote feature code

• If the digits map onto the Auto DN, the caller hears system dial tone. They can then enter:

— a target line number

— the DISA DN, which will prompt for a Class of Service

password

— a line pool access code

— a destination code

— a remote feature code from a DTMF telephone

Tips -

trunks. Each DID Trunk Cartridge also has four DTMF receivers dedicated to those trunks. A DTI can provide up to 24 DID trunks.

You cannot configure a DID trunk as the prime line for a Norstar telephone or a Business Series Terminal.

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

Analog loop start trunks

Loop start trunks give you 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 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

• 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.

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

• the DISA DN, which will prompt for a Class of Service password

• a line pool access code

• a remote feature code from a DTMF telephone

P0603534 02 Modular ICS 6.1 Installer Guide

84 / Trunks and target lines

To place an outgoing call, a loop start line can be selected by:

• pressing a line button on the telephone

• dialing a line pool access code

• pressing a memory button that has been programmed with a line pool access code

Configuration tips

• Loop start signaling is supported by Loop Start Trunk Cartridges, Call Information (CI) Trunk Cartridges and Digital Trunk Interfaces (DTI). Each Loop Start Trunk Cartridge or CI Trunk Cartridge can provide four loop start trunks. A DTI can provide up to 24 loop start trunks. If you wish to configure your loop start trunks as auto-answer, the trunks must have disconnect supervision.

• For Loop Start or CI Trunk Cartridges installed in a Trunk Module, you will also need one E&M/DISA Trunk Cartridge for every two loop start trunks that you configure as auto-answer. The E&M/DISA Trunk Cartridge provides two DTMF receivers to receive the incoming digits from the central office. An auto-answer loop start trunk can give you the same kind of direct inward dialing function as a DID trunk.

• If your system includes both loop start trunks and DID trunks, you would typically use loop start trunks for outgoing calls and DID trunks for incoming calls.

• You may configure a loop start trunk as the prime line for a Norstar telephone or a Business Series Terminal.

• The capabilities available to a remote caller are determined by the remote filters and remote package assigned to a line, or by the set restrictions, line restrictions, and remote package assigned to the Class of Service password.

• Two loopstart trunk cartridges are compatible with Modular ICS 6.1. The NT5B40GA-93 can be installed in trunk module (TM) slots only. The NT7B75GA-93 can be installed in either core slots three or four, or TM slots one, two, or three.

Analog E&M trunks

An Analog E&M trunk gives you incoming and outgoing access to other systems in a private network. E&M 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 E&M trunk, it alerts at all telephones with that line appearance.

When a call comes in on an auto-answer E&M trunk that is configured to answer with DISA, the caller hears stuttered dial tone. They must enter a six-digit COS password from a DTMF telephone to hear system dial tone.

They can then enter a:

When a call comes in on an auto-answer E&M trunk that is not configured to answer with DISA, the caller hears system dial tone. At that point they can then enter one of the following:

• a target line number

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

• a line pool access code or a destination code

• a remote feature code from a DTMF telephone

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 auto-answer. See Ans mode on page 359.

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 43.

Note Profile 2: European BRI trunks can only be EURO trunks.

PRI trunks

PRI trunks are used for incoming and outgoing calls over an ISDN network. PRI trunks are automatically set to autoanswer.

Incoming calls are routed to system telephones through assigned target lines. Outgoing calls are made using the intercom key assigned to a PRI line pool, or by entering a destination code to which a route has been defined using PRI line pools. You cannot assign a PRI line directly to a telephone.

PRI Sl-1 lines also can provide MCDN network functionality over a private network between other Norstar systems, Meridian 1 systems, or Business Communications Systems, if the appropriate keycode has been installed. Private networking is described in Networking with Norstar on page 99.

P0603534 02 Modular ICS 6.1 Installer Guide

88 / Trunks and target lines

Target lines

A target line is an internal communication path that is reached by means of digits received from an incoming trunk. Target lines are assigned to answer direct-dial incoming calls but they cannot be used to make outgoing calls.

You can program auto-answer trunks to map to target lines to provide for attendant bypass, which allows the call to go directly to a department or individual, and to create line concentration, where one trunk can map onto several target lines.

No target lines are automatically assigned to telephones, except if the DID template has been applied to the system.

Target lines are configured using line numbers 157-348 or 157-284, 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 at other telephones in the group.

Modular ICS 6.1 Installer Guide P0603534 02

Remote system access

The remote access feature allows callers elsewhere on the private or the public network to access a Norstar system by dialing directly into the system 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 systems support remote system access on the following trunk types, which may require the remote caller to enter a COS password for direct inward system access (DISA):

• auto-answer loop start trunks

• auto-answer E&M trunks

• DID trunks, by means of the DISA DN

• PRI trunks, by means of the DISA DN

The system resources, such as dialing capabilities, line pool access and feature access, that a remote user may access depends on the Class of Service (COS) assigned to the user. See Class of Service on page 93, COS pswds on page 401 and the Modular ICS 6.1 System Coordinator Guide for more details.

Use system features during a remote call

To use features on a Norstar system during a remote call-in, press •, followed by the feature code. Even if you are calling from another Norstar system or from within a private network, press • instead of ≤.

P0603534 02 Modular ICS 6.1 Installer Guide

90 / Remote system access

Remote access on loop start and E&M trunks

Loop start trunks provide remote access to Norstar from the public network. E&M trunks provide remote access from a private network. Each must be configured to be auto-answer to provide remote system access.

A loop start trunk must have disconnect supervision if it is to operate in auto-answer mode. E&M trunks always operate in disconnect supervised mode.

When a caller dials into the system on a line that has autoanswer, 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 enter a COS password. The password used by the caller determines which system capabilities are available to the caller.

Remote access on a private network

Nodes on the private network deliver the last dialed digits to the destination Norstar node, for interpretation by the destination Norstar node. The destination Norstar node either matches the digits to a target line or interprets the digits as a remote feature request. The call is either routed to the specified target line, or the remote feature is activated.

By default, E&M trunks are set to answer with DISA. For auto-answer E&M trunks connected to a private network, change the default so that the trunks are not answered with DISA. If an auto-answer E&M trunk is configured to answer with DISA, the system tries to interpret any received digits as a COS password.

Modular ICS 6.1 Installer Guide P0603534 02

Remote system access / 91

The DISA DN and the Auto DN allow auto-answer private network and DID calls, in the same way that calls on auto-answer loop start and auto-answer E&M trunks can be answered, with or without DISA. These DNs are described in System prgming under Access codes.

Remote access on Direct Inward Dial (DID) trunks

Remote system access on DID trunks is similar to that of E&M trunks connected to a private network.

The main differences are:

• a remote caller is on the public network dialing standard local or long-distance telephone numbers

• the digits received are delivered by the central office

• DISA cannot be administered to a DID trunk

As with a private network, the dialed digits may be programmed to match those of a specific target line DN, the DISA DN or the Auto DN.

Remote access on PRI trunks

Remote system access on PRI trunks is similar to that of E&M trunks connected to a private network.

The main differences are:

• a remote caller is on the public network dialing standard local or long-distance telephone numbers

• the digits received are delivered by the central office

• answer with DISA cannot be administered to a PRI trunk since PRI trunks are set to autoanswer.

As with a private network, the dialed digits may be programmed to match those of a specific target line DN, the DISA DN, or the Auto DN.

Controlling system access

Modular ICS programming provides several ways of protecting your Norstar system from unauthorized access or use. These features are used in combination to provide control both to users and to lines.

Class of Service

Class of Service (COS) refers to the capabilities that Norstar provides to users who access the system from the public or private network. A password defines which set of capabilities the user has access to.

The COS includes:

• filters that restrict dialing on the line

• an access package 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 Class of Service 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 class of service by dialing the DISA DN and entering a COS password.

To program COS passwords, see Passwords on page 401 and the Modular ICS 6.1 System Coordinator Guide.

P0603534 02 Modular ICS 6.1 Installer Guide

94 / Controlling system access

Restriction filters

Restriction filters can be used to restrict the numbers that may be dialed on any external line within your Norstar system. Up to 100 restriction filters can be created for the system.

A restriction filter consists of up to 48 restrictions with associated overrides.

To restrict dialing within the system, you can apply 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 Restriction Service, for times when the system is operating according to a Schedule. See Services on page 371 for more details.

Dialed digits must pass both the line restrictions and the set restrictions. The line/set restriction overrides the line restriction and set restriction. Refer to the following diagrams.

Networking with Norstar

There are a number of ways you can network Norstar systems together, or network Norstar systems with other Nortel systems into private networks. What types of lines you use to perform the networking will determine the type of services that can be shared between systems.

Keep in mind that each node (Norstar system) is considered an external system by every other node within the network, even though, to the users, it appears to be all one system. This affects how you configure call transfer and call out features on each system. On the home node, all features are configured as local numbers. On all other nodes, all features directed to the home node are configured with external numbers.

As well, each node must have a unique identifying code. What this code will be, and how it is configured for the user, depends on what type of trunks and dialing rules you choose to use. If the network has a Meridian as part of the network, the Meridian administrator will determine identification codes for the systems.

This section describes various configurations of private networks. The general settings that are required to set up the home node for each system are provided to give you a sense of what is required for each type of network.

The common goal is to provide the user with the sense that the network is one large system that provides common access to colleagues in other buildings, cities, or countries. In some systems they may need to enter a destination code before the local number to route the call to the correct system. In other systems, using a common dialing plan allows users to dial colleagues at any location simply by entering the same number of digits they would use to dial a colleague at the next desk.
