Chapter 1 — Introducing the Option 11C Mini

This chapter provi des an overview of the Option 11C Mini syste m.

Option 11C Mini system description

The Option 11C Mini is a small communications syste m based on existing Option 11C technology. The system provides full Meridian 1 feature functionality. The Option 11C Mini uses X11 global software which other Meridian 1 systems also use.

In an Option 11C Mini system, the Main Chassis can connect to a Chassis Expander. This increases line size to 144 lines. Two copper cables connect the Chassis Expander to the Main Chassis.

The Main Chassis a nd Chas sis Expander each pro vide four Intelligent Peripheral Equipm ent (IPE) card slots. These card slots support line cards, trunk cards, and application cards used in other Meridian 1 systems. The Option 11C Mini introduces a 48-port Digital Line Card (NTDK16). You must insert the 48-port Digital Line Card in a dedicated slot (Slo t4) of the Main Chassis. The Ma in Chassis a lso provi des a de dicated sl ot (slot 0) for the Mini System Controller (MSC) card.

A processor located on the Mini System Controlle r (MS C) ca rd in the Main Chassis handles call processing, serial ports, and network traffic. Call processing on the MSC card is equivalent to that on the Option 11C Small System Controller (SSC) c ard. Use the MSC card for configurations with up to 144 lines.

Installing software and configuring data

The Option 11C Mini support s a minimum of X11 Release 24.24 software. Everything from gene ral business features to ad vanced applications are available. The software cont ains all of the components rel ated to a relea se of software. These components include software patches, preconfigured customer database, feature sets, and other re lated databases and software.

When you perform an inst alla tion for th e fir st time , use the MSC ca rd for the installation. When you upgrade to a new softwar e rel ea se, use a Software Delivery card (PCMCIA card).

Flash Drives

Two Flash Drives, located on the MSC card, perform Meridian software operation and cu st omer data storage.

The first flash device is the Primary Flash Drive. The Primary Flash Drive contains Meri dian syst em d ata and the firs t copy of cust omer d ata r equire d t o load and run th e switch. T he Primary Fl ash Drive i s programmed wit h system software before it is shipped to the customer.

The second Flash Drive is the Backup Flash Drive. The Backup Flas h Drive stores fi les th at t he u ser can ch ange. Exampl es of t hese fil es are co nfigu rat ion data and the second copy of the customer database . If the Primary Flash Drive fails, you can retrieve a backup set of customer da ta. After the backup set of customer data is retrieved, you can load it into the system’s active database.

Software Installation Program

The Software Installation Program starts during initial installations of the Option 11C Mini system. This program is menu driven.The Software Installation Program installs the software and puts the Option 11C Mini into operation.

Software Delivery Card

The Option 11C Mini uses a Software Del ivery card (PCMCIA) card to upgrade system software and provide storage for a ba ckup copy of cust omer data. The Option 11C Mini uses the same Software Delive ry card that the Option 11C uses.

Insert the Software Delivery card in the socket (slot A) located on the faceplate of the MSC card. When ins erted, you can load software and customer databases from the Softwar e Delivery card to the MSC card.

Option 11C Mini Planning and Installation Guide

Page 20 of 332 Chapter 1 — Introducing the Option 11C Mini

Security Device

A Security Device comes with each new Option 11C Mini system. Attach the Security Device to th e component s ide of the MSC c ard at the tim e of initial installa ti on. The S ecurit y Devi ce remains on the MSC card for the li fe of the system. The Security Device is used for system identification. This device allows the activation of features ass igned to the system, t hrough the use of a series of keycodes. The system uses keycodes for vali dation purposes.

Configuring data

The Option 11C Mini provides several options for m aking data configurat ion easier.

Preprogr a m m ed data

When you first install an Option 11C Mini system, you mu st enter customer data into the overla y program s. Tele phones , for example , must have fea tures assigned to their keys, in order for them to function correc tly. Data can be preprogrammed. If you load preprogrammed data during the installation process, the system automatically configures some overlay entries on the telephones.

If the preprog rammed da ta doe s not a pply to users at on e o f th e sites, you can revise the data on-site with a TTY. You can also revise the preprogrammed data remotely over a modem connection. You can start with a basic configuration. A basic configuration is the least possible amount of data required for init ial sof tware progr amming. You must perform this step while you are working in the Softwa re Ins tallation Program.

Model telepho ne s

You can select many different preprogrammed mode l telephone layouts. Technicians can perform some basic steps at installation to activate multiple telephones, using telephone layouts or templates.

Administration telephones

If you use default model layouts for telephones and trunk routes, use an administrat ive telephone to make adjustments to items, such as numbering plans and access codes. You do not need a TTY input terminal for programming the Option 11C Mini unless you require a custom layout.

You can use the M2616 and M2008 digital telephones for admini st rative functions. The administrative te lephone can double as a user’s working telephone.

Reserve power supply

You can use an Uninterruptible Power Supply (UPS) to provide a backup power supply for the NTDK91 and the NTDK92 chassis . A UPS provides a continuous AC powe r supply. Install the UPS unit according to the manufacturer’s instruct ions. Refer to “Power consumption worksheets for the Option 11C Mini system” on page 64. This section contains worksheets to help you determine the power draw for the UPS.

Circuit cards

The Option 11C Mini intr oduces the NTDK97 Mini System Contro ller (MSC) card and the NTDK16 48-port Digital Line Card. This section provides a short overview of these two cards. For more inform ation about these cards and the other circuit cards supported on the Option 11C Mini, refer to “Chapter 12 — Insta lling the circuit cards ” on page 147.

NTDK97 Mini System Controller card

The NTDK97 Mini System Controller (MSC) card is based on the Option 11C NTDK20 Small System Controller (SSC) card. The MSC card includes a Central Processing Unit (CPU) which handles call processing for the system. The MSC card also i n cludes an Etherne t controller, storage for system and customer da ta, and syste m mem ory.

The MSC card stores system and customer data. This ca rd is programmed with system s oftware before it is shipped to the c ustomer. Ad ditional memory on the MSC card temporarily stores and processes automated routines and user-programmed commands. The MSC card also keeps a copy of customer files in the event of data loss on the Backup Flash Drive.

You must install the MSC card in Slot 0 of the Mai n Ch assis.

Security Device

The MSC card is equipp ed with a socket. This socket ho ld s the Secu r i ty Device. Each new Option 11C Mini system comes with a Security Device. You must attach the Security Device to the MSC card during initial installation.

PCMCIA interface

The NTDK97 MSC ca rd ha s a 2-sl ot PCMCIA inte rface soc ket l ocate d o n its faceplate. You can insert a S of tware Delivery card into the socket. Use the Software Delivery card for software upgrades on an existing Option 11C Mini system. You can also use this socket for creating an external backup copy of the customer database.

Before you install an Option 11C Mini and before you apply AC power, measure the impedanc e of the building ground refere nce. An ECOS 1023 POW-R-MATE, or another meter like the POW-R-MATE, is acceptable for this purpose. If the ground path connected to th e Option 11C Mini has an impedance of 5 Ohms or more, make better grounding arrangements. Make any improvement s to the grounding s ystem before you install the Opti on 11C Mini.

Option 11C Mini Planning and Installation Guide

Page 48 of 332 Chapter 3 — System and site requiremen ts

The following are addi tional grounding requirements:

CAUTION

Never connect the single point ground conduc tor from the Option 11C Mini system to structural steel members or electrical conduit. Never tie this conductor to a ground source or grounded electrode that is not hard-wired to the building reference conductor.

• Ground conductors for the Option 11C Mini system: — must not be smaller than #6 AWG (#40 metric) at any point (see

Table 10 on page 49. This table provides a list of grounding wire requirements spec ific to som e areas)

— must be routed through the same condui t as the phase conductors

that serve the system — must not be smaller than any phase conductor in the same conduit — do not carry current under normal operating conditions

• All ground conductors in the building: — must be isolated from the neutral bus exc ept at the service entrance

to the bu ilding

— must be hardwired to the main ground refere nce

• Avoid spliced conduc tors. Continuous conductors have lower impedance, and they are more reliable than spliced conductors.

553-3021-209 Standard 3.00 April 2000

Chapter 3 — System and site re quirements Page 49 of 332

• All conductors must terminate in a permanent way. Make sure all terminations are easily visible and ava ilable for maintenan ce pur poses.

• Tag ground connections with a clear message such as “CRIT ICAL CONNECTION: DO NOT REMOVE OR DISCONNECT”.

CAUTION

For an installe d Option 11C Mini, the impedance of the link between the ground post of the Main Chassis and the single point ground to which it connects must be less tha n 0.25 Ohms.

CAUTION

Trans ients in supply conduct ors and ground systems can damage integr ated circuits. This da mage can result in unreliable Option 11C Mini operation. Damage caused by transients is not always immediately apparent. Degradation ca n occur over a period of time .

Ground bus isolation (Canada and the United States)

According to the ex ce ption to article 384-20 in the United States Natio nal Electrical Code (NEC), a panel’s ground bus can be isolated from the housing. Thi s e xception applies provided that the panel is not at the ma in service e ntranc e. This exc eptio n applies to some C anadian lo catio ns also . For more information about ground bus isolation, refer to local electrical codes.

CAUTION

Do not isolate the ground bus from the housing unles s permitted by local electrical codes. Do not perform work inside electrical panels unless you are a qua lified electrician. Do not try to remove bonding conductors without approval from qualified personnel.

CAUTION

Route ground conductors, between supply panels, through the same conduit as the supply conductors. This safety requirement is part of both the National Electrical Code (NEC) an d the Ca nadian Electrical Code (CEC).

Single Point Grounding (SPG)

Correct grounding of communications systems is necessary for protecting equipment from th e hazards of surge a nd noise int erference. The Sing le Point Grounding (SPG) method of protecting communications equipment is the Nortel Networks standard for Meridian 1 systems.

The requirements for Single Point Grounding are in the following major categories: Safety, Protection, EMC, Installation and Maintenance, Powering, and Advances in Tech nology.

Safety

For a safe working environm ent, your grounding system must be abl e to dissipate unwanted surge energies, suc h as lighting on the outside plant. The grounding sys tem must be desi gned so that fu se or breakers ope rate to di srupt the excessive current f lo w caused by a power fault.

553-3021-209 Standard 3.00 April 2000

Chapter 3 — System and site re quirements Page 51 of 332

Protection

Correct grounding is a necessary component of the protection system for equipment. T his groundi ng include s grounding for outs ide plan t cable shields and protecto rs , and the grounds for fr am ework, battery, and logic references.

EMC

To make sure that there is good e mission and susceptibility performance of the equipment , yo u must c onside r the E lect romagne tic C ompati bilit y (E MC) grounding requirements.

Installation and Maintenance

A grounding syst em is c ost eff ectiv e to insta ll and mai nta in when it is pa rt of the initial electrical installation for the customer’s premises. If you try to correct violations of national codes af ter the initia l installation, it is both difficult and costly.

Powering

The grounding syst em must consider the power options for the equipment. The grounding syst em must consider if the equipment is backed up with an Uninterruptible Power Supply (UPS ). Consider the grounding and powering of all equipment that is part of the telecommunications system as one large system. Perform the installation taking this information into consideration.

Advances in Technology

The component density on circuit cards continues to increase be cause of the miniaturization and multi-layering of printed circui t boards. The operating speeds of the integrated circuits are ever increasing. Grounding provides protection for these components, and is very im portant.

The SPG of a system is the point at which telecommunications equipment bonds to the ground. A copper busbar normally acts as the system SPG.

Option 11C Mini Planning and Installation Guide

Page 52 of 332 Chapter 3 — System and site requiremen ts

You can use any of the following busbars as a system SPG:

• building principal ground, normally in building with one floor

• floor ground bar, normally in buildi ngs with m ore than one floor

• dedicated SPG bar bonded to the building grounding system

• a section of the battery return bar of the power plant

You can configure subsystems of a telecommu nications syste m, suc h as groups of frames or equipm ent, as separate single poi nt ground entities connected in a star configuration to the system SPG.

Grounding method

To prevent ground loops, power all chassis from the same dedicated power panel. Ground all Main Chassis to the power pane l through the grounding block. Ground the Chassis Expander to the Main Chassis.

The method of grounding used for the Opt ion 11C Mini d epends on whether the same service panel powers all chassis.

The following three grounding scenarios ar e possible:

A system with one chassis

A syst em wi th mor e th an o ne chas si s, p ow ere d b y th e sa me serv ic e p ane l

For each Main Chassi s, conne ct a # 6 AWG (#40 Metri c Wire Gauge) grou nd wire from the chassis to the NTBK80 grounding block. See Table 10 on page 49 for grounding wire requirements specific to s ome areas. If any chassis cannot be powered from the same service panel, gr ound it separately from the other chassis back to the service panel that supplies it.

Grounding multiple pieces of equip ment in a rack/ca binet

You must ground each piece of equipment in a rack/cabinet. If a piece of equipment does not have a ground lug, then ground the whole rack/cabinet.

If a chassis req uires a separa te ground, ground it usi ng the same

In the UK, you can conn ect the gro unding wire from the chassis

Conduit req uir em ent s

Conductive conduit linking panel s and equipment are legal for use as a grounding network in most countries. For all sy st em ground paths for the Option 11C Mini, us e the correct size of insula ted copper conductors routed inside conduit when possible. A ground link that depends on conduit ca n defeat the improvements made by installing de dicated panels and transformers . The following are the reasons why:

• Personnel who service diff ere nt equi pment can s eparate co nduit li nks. If this separation occurs between the Option 11C Mini system and the building grou nd reference, the conduit cannot provide a ground path. This situation is a hazardous.

• Metal conduit often corrodes, especially at threaded connections. Corrosion increa ses resi stan c e. This pro ble m becomes worse when multiple li nks are involved. If you apply paint over the conduit, it is possib l e th a t th e co r r o s i on pr o cess wi ll occur mo re quickly.

• Always fasten conduit to secure surfaces. Often, condui t is bolted to structura l st ee l me mb ers, which can function as ground conductors to noisy equipment (for example, compressors and motors). The co upling of these noisy si gnals into the Option 11C Mini grounding system can damage its performance. The resulting intermittent malfunctions can be difficult to trace.

Commercia l po w e r requir ement s

The Option 11C Mini system is available with AC-power only.

The optimal installation of the AC-power ed Option 11C Mini system includes a di rect c onne ction t o th e ele ctric al syst em in t he b uilding , pr ovided some requirement s a re met. Refer to AC-powered insta llation later in thi s chapter for detai led information. The Main Chassi s and Chassis Expander can share the same electrical breaker .

You can use an approved isolation transformer for AC-powered systems when meeting the optimum requirements is not possible or is too expensive. See “Alternative AC-powered installation” on page 58.

Refer to “Power consumption worksheets for the Option 11C Mini system” on page 64 to determine the power consumpt ion of the Option 11C Mini.

AC power installation for systems installed on a wall or table

Use a dedicated AC ser v ice panel with the Option 11C Mini system. Do not connect equi pme nt that is not related to the Option 11C Mini to this panel. Keep all light ing, fans, motors, air conditioning equipment, and the like, as “electrica lly separate” from the Option 11C Mini system as possible. The Main Chassis and Chassis Expander can share the same AC breaker.

AC power installation for systems installed in a rack/cabinet

If other data communications equipment is in the same rack/cabinet as the Option 11C Mini, power each piece of equipment from an isolated ground outlet. The same service panel must service all outlets.

Power from each outlet mus t meet the input requirement s of at least one Option 11C Mini power supply, as listed in Tables 11 through 13. Check power requirement s for ot her s ystem equipment. Install additional outl ets if you need to.

Site requirements

The following is a list of required site features f or an optimal Option 11C Mini AC-powered system installation.

If a dedicated panel cannot provide the conditions listed below, use an Isolation Transf ormer. Refer to “Alternative AC-powered installation” on page 58.

• Dedicated circuit breaker panel

A dedicated circ uit breaker panel provide s power only to th e Option 11C Mini system and its rela ted hardware, such as TTYs and printers

You can not always power a complete system from a singl e

Note:

circuit-breaker panel. For example, when chassis are located remotely.

• Insula ted copper ground condu ctor

Insulated copper ground conductor connects the ground bus in the dedicated panel to the main service panel ground or building ground reference. Route the insulated copper ground conductor through the same conduit as the sup p ly conductors that feed the panel.

• Isol ated-ground receptacles

All outlets connected to the dedicated panel must be of the isola ted ground type. Use a separa te circuit for each devic e con nected to the panel. Outl ets that provi de servic e to the c hassis must be close enough s o that the power cord can reach the chassis power supply.

• Isolated ground bus in the electrical panel, where permitted by local codes

Page 58 of 332 Chapter 3 — System and site requiremen ts

Location of po we r ou t lets

The maximum distance between a power outlet a nd the system chassis depends on the lengt h of the powe r cord. In North America, the power cord is 9 ft 10 in. (3000 mm). In countries outsid e North America , the power cord is 8 ft 2 in. (2490 mm).

Alternative AC-powered installation

If a dedicated panel c annot provide optimal conditions, use an Isolation Transformer with the following characteristics:

• 120/208/240 VAC input, over-current protected at primary

• 120/208/240 VAC available at s econdary outputs, each circuit breaker-protected

• Completely isolate primary and secondary windings from one another

• Approved for use locally as a stand-alone use r product (CSA, UL, or other locally recognized clear markings)

• Capable of providing power to all Option 11C Mini system equipment operating at the same ti me at full load

• Equipment not related to the Option 11C Mini system must not be powered from a transformer that provides service the Option 11C Mini system.

Uninterruptible Powe r Su ppl y

For backup AC power, you can use an Uninterruptible Power Supply (UPS) to feed the Opti on 11C Mini . The power requ irement for a UPS is 550 VA per system. The maximum power requirement for a Main Chassis and a Chassis Expander on the same breaker is 1100 VA. Ins tall the UPS according to the manufacturer’s instruct ions.

Isolation tr a nsf o rm e r ground

The transfor mer gr ound m ust have the following characteristics:

• Separate grounds for primary and seconda ry windings, rather than a common ground

• A “clean” and permanent SPG re ference at the transfor mer secondary f or the Option 11C Mini system

Make sure that the ground conductors inside the transformer are sized correctly.

Receptacles

Receptacle requirements are as follows:

• When installed on the wall, i nstall re cept acles wit hin rea ch of the cha ssis power cords.

• All receptacles served by the secondary must be of the isolated ground type

• The ground prong of each outlet must be connec ted by an insulated conductor to the system SPG

If the trans former has an isolated secondary ground lug, use it as the SPG. If it does not, use the chassis ground of the transformer as the Single Point Ground.

Installing an Isolation Transformer

Transfor me rs wi t h pl ug ga b le po we r co rds:

Connect the power cords of all Option 11C Mini system equipment to the

outlets on the transformer secondary. Secure an insulat ed conductor between the ground lug on the Main

Chassis of the Option 11C Mini and the SPG lug on the transformer. Place a “DO NOT DISCONNECT” tag on it.

Do not fasten or ti e th is co nductor t o the power ca ble feedi ng the Option 11C Mini.

Power all equipment related with the Option 11C Mini from the

Transformers without pluggable power cords

If the transformer does not have a pluggable cord, hardwire the transformer to an electrica l panel. Route all wires (including grounds) through a single conduit.

Some electri cal c odes permit t he use of conduit as the only gr ound c ond uctor between pieces of equipment.

Run a separate insulated ground con ductor through the c onduit to hold cha ssis grounds together. Such a conductor maint ains the safety ground co nnection in the event that the conduit becomes corroded or disconnected.

Chapter 5 — Regulatory information

This chapter includes regu la tory information for American, Canadian, an d International installations of the Option 11C Mini.

System approval

All global markets approve the Option 11C Mini sy stem. The Option 11C Mini has a regulatory label on the back of each sys tem chassis. This label contains national and internat ional regulatory inform ation.

Notice for United States installations

The Option 11C Mini system follows Part 68 of the FCC rules. A label containing the FCC registration numb er and Ringer Equivalence Numbe r (REN) for the Option 11C Mini equipment is on the back of each system chassis. Pro vide this information to your telephone company, if it requests FCC registration number and REN information.

Importance of Ringer Equivalence Number

The FCC regulati on label includes the Ringer Equivalenc e Numb er (REN). This number repr esents the el ectrical loa d applied t o your telepho ne line after you plug the PBX into the wal l jac k. The telephone line for your premises does no t op erate c orre ct ly if t he to ta l ri nge r l oad ex ceeds th e ca pa bility of the telephone company’s Central Office (CO) equipme nt. If there are too many ringers connected to the line, there may not be enough ener gy to ring your system. If the ringer load exceeds the system’s capabilities, you may also have problems dia ling telephone number s.

For more information about the total REN permitted for your telephone line, contact your local te lephone compan y. However, as a guidel ine, a total REN of five should allow for normal operation of your equipment.

Option 11C Mini Planning and Installation Guide

Page 84 of 332 Chapter 5 — Regulatory information

If your Meridian 1 Opti on 1 1C Mini e quip ment cause s harm to the tele phon e network, the telephone company can discontinue your service temporarily. The telephone company can ask you to disconnect the equipment from the network until the problem is corrected. The telephone company can ask you to disconnect the equipment until you are sure the equipment is working correctly. If possible, the telephone company will notify you before they disconnect the equipment. You will be notifie d of your right to file a complaint with the FC C.

Your telephone company can make changes in its facilities, equipment, operations, or proc edures that can affect the correct operation of your equipment. If the te lephone company does make changes , they will give you advance noti ce. With advance notice, it is possible for you to make arrangements to maintain uninterrupted service.

If you experienc e trouble with your Opti on 11C Mini equipment, contact your authorized distributor or servic e center in the United States for r epair or warranty information.

Hearing aid compatibility

All proprietary telephones used with the Meridian 1 Option 11C Mini meet with the require me nts of FCC Part 68 Rule 68.316 for hearing aid compatibility.

Notice for Canadian installations

The Industry Canada label identifies certified equipment (Industry Canada was the Canadian Departmen t of C ommunicati ons). This certi fic ation me ans that the equip ment meets certain operati ons, safety, and protection requirements for tel ec om munications networks. The Department doe s not guaran tee that the eq uipment will operate to the user’s s atisfaction.

The Load N umber (LN) assig ned to each termina l devi ce is the p ercent age of the total l oad tha t can b e conne cted to a tele phon e loop using th e device . Th is number prevents overload. The termination on a loop can have any combination of devices, provided that the total of the Load Numbers does not exceed 100. An al phabetical s uffix is also de fined i n the Load Numbe r for the appropriate ringing type (A or B), if neces s ary. For example, LN = 20 A indicates a Load Number of 20 an d an “A” type ringer.

553-3021-209 Standard 3.00 April 2000

Chapter 5 — Regulatory information Page 85 of 332

Before you install any equipment, must make sure that it can connect to the facilities of the local telecommunications company. You must install the equipment using an acceptable method of connection. In some cases, a certified connector assembly (telephone extension cord) can extend the company’s inside wiring associated with a single line individual service. Understand that compliance with the abo ve conditions does not always prevent degrad ation of service.

An authorized Can adian maintenance facilti y, identified by the su pplier, must make repairs to cert ified equipment. If you make repairs or modi fications to this equipment (or if the equipment malfunctions), the telephone company can ask you to disconnec t the equipment.

Make sure that the electrical ground connections of the power utility, telephone li nes , and internal metal lic water pipe system, if presen t, connect together. T his p recaut ion is for the users ’ pr otect ion, a nd is very important in rural areas.

CAUTION

The Option 11C Mini frame ground of each system chassis must be tied to a reliable building ground reference.

WARNI NG

Contact your local electrical inspection authority or electrician to make electrical ground connections.

Notice for international installations

If there is not enough planning or technical information available for your country of operati on, contact your regional distributor or authority for help.
