Toshiba Strata DK & Nortel Norstar
Product Comparison
Introduction
The Nortel Norstar product line consists of three models:
♦The Norstar 3x8 system is the smallest model and provides capacity for three CO lines and
eight stations. The Norstar 3x8 has been around since 1988 and is a very outdated system.
It is still available although not very heavily marketed. It has a limited feature set
compared to the other Norstar models.
♦The Norstar ICS Compact is similar to the larger Norstar ICS Modular in feature content,
but the KSU hardware is different. The Norstar ICS Compact has built-in capacity for four
lines and eight digital stations, and grows to a maximum capacity of 8 CO lines and 24
stations.
♦The Norstar ICS Modular is the largest Norstar system, offering modular expansion up to
maximum capacity of 272 ports (must use T1 or PRI to achieve 272 ports). None of the
Norstar equipment is upward compatible with the larger Meridian™PBX systems.
All Norstar models use the same digital telephones that Nortel has sold since 1988. No other
Nortel telephones are compatible with the Norstar. Norstar telephones are not compatible with
any other Nortel systems.
In addition to the Norstar product line, Nortel also has Meridian PBX systems. Two models
called the Meridian Option 11C and Option 11C Compact are available in line/station sizes
positioned directly above the Norstar.
The Toshiba Strata DK product line consists of three models:
♦The Strata DK14 system is the smallest model and provides capacity for four CO lines,
eight digital stations, and two analog stations. The Strata DK14 has a very comprehensive
feature set compared to the Norstar 3x8.
♦The Strata DK40i has similar feature content to the larger DK424, but the KSU hardware
is different. The Strata DK40i provides maximum capacity of 12 CO lines and 28 stations.
♦The Strata DK424 is Toshiba's largest system, offering modular expansion up to maximum
capacity of 432 ports.
All Strata DK models use the same digital telephones. Previous generations of Toshiba
telephones are also compatible with Strata DK systems, providing excellent investment
protection.

Strata DK Advantages Over Norstar
Larger Maximum Capacity
Strata DK systems provide larger capacities than their Norstar counterparts. This allows the
Strata DK systems to address a larger segment of the market. It also protects the customer’s
investment better because they are less likely to outgrow the Strata DK than the Norstar.
♦The Strata DK14 provides larger CO line and station capacity than the Norstar 3x8. The
Strata DK14 supports up to 4 CO lines and 10 stations, while the Norstar 3x8 supports
three CO lines and eight stations.
♦The Strata DK40i provides larger station capacity than the Norstar ICS Compact. The
Strata DK40i supports up to 12 CO lines and 28 stations, while the Norstar ICS Compact
supports 8 CO lines and 24 stations.
♦The Strata DK424 provides significantly larger capacities than the Norstar ICS Modular.
The DK424 supports up to 432 ports, while the Norstar only supports up to 272 ports.
Configuration Flexibility
Addition of CO lines and stations must be done in relatively large increments with the Norstar
ICS Modular. Each CO line expansion module holds three line cards, with each card
containing four CO line circuits (12 total per module). Each Station expansion module
contains either 12 or 16 station circuits. This makes small additions less cost effective than
larger additions. With the Strata DK424, CO lines are added in increments of four or eight, and
stations are added in increments of eight per card. Combo cards allow mixture of standard
ports and digital station ports. PCB slots are universal, allowing any mix or CO line or station
cards required. This provides better configuration flexibility and better resource utilization
with the Strata DK424.
Remote Expansion Cabinets
The Strata DK424 can be configured with expansion cabinets either co-located with the base
cabinet, connected by copper data cables, or remotely located, connected by fiber optic cables
in a distributed configuration. Remote expansion cabinets may be installed up to three cable
kilometers (1.8 miles) from the base cabinet, meeting the needs of distributed configurations
such as campuses, resort complexes, and skyscrapers with a single telephone system. This
greatly extends the effective station loop distances and can sometimes eliminate the need for
multiple telephone systems. Feature operation for all users in the system is the same regardless
of whether they are served by local or remote expansion cabinets. The Norstar lacks this
important capability.
Telephone Set Compatibility
Norstar telephone sets are not compatible with any other Nortel systems. If a customer is
upgrading from another smaller Nortel system the telephones are not compatible with the
Norstar, or if the customer outgrows the Norstar and migrates to a Nortel PBX, the telephones
are not compatible. All Toshiba telephones are compatible with all Strata DK systems. The
Toshiba telephone set migration provides growing businesses a significant cost savings, since
about half the cost of a telephone system is in the telephone sets. This is an extremely
important consideration in protecting the buyer’s investment in any telephone system.

Toshiba Strata DK & Nortel Norstar Product Comparison
Strata DK Advantages Over Norstar
Strata DK 12/99 3
Telephone Set Design
Toshiba 2000 series digital telephones are aesthetically and ergonomically designed according
to what most people want. By contrast, studies show that the Norstar telephones are too big
and take up excessive desk space, especially the M7310 and M7324 models. The handset has
been criticized as unbalanced, too wide and flat, and not as comfortable as a more standard
design like the Toshiba. Studies also show that most people prefer the greater visibility of LED
indicators for buttons over the Norstar’s LCD indicators. Toshiba digital telephones have both
red and green LEDs to make status indication very clear.
Automated Attendant
Built-in Automated Attendant is available as an inexpensive option on Strata DK systems.
This is especially valuable in smaller systems, where voice mail is either too expensive or not
required for simple auto answering applications. The Norstar ICS Compact offers a built-in
Auto Attendant option, but other Norstar models do not. Auto Attendant is only available as
part of a voice mail system, or by adding an external Auto Attendant sub-system, which also
gets expensive.
BLF Display
The BLF module that attaches to the model 7310 Norstar telephone does not show the
extension numbers of busy stations. Busy stations are signified by a darkened half rectangle on
the BLF according to their relative position. The attendant must keep a reference card handy or
memorize whose extension is in each relative position to know who is on the phone. With
Strata DK, BLF extension status can be clearly displayed by extension number on an LCD
telephone without needing an add-on module. With an add-on module (20-button or 60-button
DSS), full DSS/BLF functionality is provided with LED indicators next to extension numbers.
Standard Telephone Interface
An analog terminal adapter is required for each standard 2500 set attached to the Norstar ICS
Compact. These units cost about $190 list/$275 retail so use of 2500 sets is very expensive.
Also, the ATA units are large and heavy, taking up more wall space next to the KSU. Any
analog device (modem, FAX, answer machine, credit card reader, OPX 2500 set, etc.) must be
interfaced through an individual ATA. With the Strata DK40i, 2500 sets and all analog DTMF
devices plug into a standard telephone interface card in the KSU. The DK40i provides four
optional circuits in the base KSU, and eight circuits per card in the expansion KSU, up to 20
maximum standard circuits. A combination card is also available, providing two or four
standard circuits and four DKT circuits. Also, the DK40i can light the message waiting
indicator on standard telephones. This provides a much more flexible and cost effective
interface for standard devices than the Norstar ICS Compact offers.
Direct Inward Dialing (DID)
The Norstar ICS Compact does not support Direct Inward Dialing. Strata DK40i users find
DID to be very useful feature.
Tie Lines
The Norstar ICS Compact does not support Tie lines. Multiple location Strata DK40i users
find Tie line capabilities to be very useful.

Strata DK Advantages Over Norstar
4Strata DK 12/99
Automatic Number Identification (ANI)
The Norstar ICS Compact supports Caller ID on loop start lines, but does not support ANI.
The Strata DK40i supports ANI over analog DID and Tie lines in addition to Caller ID on loop
start lines.
Dialed Number Identification Service (DNIS)
The DK40i supports DNIS on analog DID and Tie lines. DNIS is very useful to identify the
number dialed by the calling party, regardless of which line the call comes in on. The Norstar
ICS Compact does not support this valuable feature.
Multiple Directory Numbers
The Norstar’s Answer buttons enable multiple calls to be answered at the user’s telephone, but
are no substitute for true multiple appearing directory numbers that the Strata DK systems
provide. The Norstar ICS Modular DID numbers (not regular DNs) can appear more than once
on a DKT and can appear on another telephone, providing limited multiple DN appearances,
but does not support phantom DNs like Strata DK. True Multiple DN capabilities provided by
Strata DK enables the ultimate efficiency in call coverage.
LCD Messaging
The Norstar has very weak LCD station-to-station messaging capabilities. It lacks many
important messaging capabilities Strata DK systems have, including 40 alphanumeric standard
system messages, 10 alphanumeric personal messages, busy station messaging, group station
messaging, and timed reminders. The only LCD messaging the Norstar has is nine standard
system callback messages. The only modifying a station user can do is on a call back request
that says, “Jill called,”where you can only insert your own name or extension. There are no
custom messages. Nortel's defense of this weakness is only by saying that creating and using
custom messages would be too difficult to make it practical. This is not the case with Strata
DK systems. Once created through dial pad entry, custom messages are easy to use.
Call Duration Timer
The call duration timer on the Norstar phones requires the user to dial a feature code to briefly
display call duration, then it disappears. It is not displayed continuously while the call is in
progress, as with the Strata DK. It would be easier to look at your watch than keep dialing
display codes on the Norstar.
Directory Speed Dialing
LCD dial-by-name directory speed dialing is provided by software that runs on a dedicated
personal computer attached to the Norstar system. This requires costly additional hardware, in
addition to software that will have to be licensed separately from Nortel. Strata DK systems
can support the same capability with keyboard dialing from a PC, and can also provide a much
more cost-effective solution for LCD directory speed dialing with built-in capabilities not
requiring an external application processor.
Account Codes
The use of account codes on Strata DK systems is more flexible than the Norstar. Account
codes on the Strata can be voluntary, forced, verified, or forced and verified. Strata DK
systems provide up to 300 forced and voluntary account code entry of 4~15 digits. The Norstar

Toshiba Strata DK & Nortel Norstar Product Comparison
Strata DK Advantages Over Norstar
Strata DK 12/99 5
ICS provides a total of 100 account codes of which only six digits are verified. This is not
adequate for many account code applications. To get true account code capabilities with the
Norstar, the Call Detail Recording (CDR) package must be running on a PC attached to the
system.
System Battery Backup
The Norstar does not provide battery backup to keep the system operating when commercial
power is lost. An optional uninterruptable power supply (UPS) is available for reserve power,
but it is expensive by comparison. The Strata DK40i and DK424 systems provides battery
backup interface as a standard feature. All you need to add is batteries. This type of built-in
battery backup is much more cost effective than UPS.
Automatic Busy Redial
No Automatic Busy Redial feature exists in the Norstar. Nortel suggest continually pressing
the Redial button until getting through, but this is no substitute for ABR. Auto Busy Redial is
a widely used and very popular standard feature of Strata DK systems. This is a particularly
valuable feature in heavy outgoing call applications frequently encountering busy outside
numbers.
Off-hook Call Announce (OCA)
The Norstar’s Priority Call feature is a poor substitute for OCA. It announces through the
handset, not through the handsfree speaker. It is cumbersome and complicated to use, and
automatically puts the called party’s active call on hold if they don’t react quick enough to the
priority call warning tone. If the called party presses the release key after the priority call is
completed, the holding call will also be disconnected. The Strata DK’s OCA works much
smoother, more efficiently, and does not cause complications. Also, the Strata OCA can
announce either through the handset or optionally through the speaker, giving individual
station users a choice to suit their preference.
Remote Retrieval of Held Calls
The Norstar call pickup feature can only answer calls ringing at other stations, and will not
retrieve held calls remotely. The only way other stations can remotely retrieve a held call is if
they have that CO line appearance on their telephone set. This is a significant limitation in
non-squared installations. Strata systems can remotely retrieve held calls from any stations by
dialing an access code, similar to retrieving a parked call.
Tenant Service
Tenant service enables two businesses to cost effectively share one Strata DK14 or DK40i
system and four businesses can share one DK424. The Norstar does not provide this feature.
Station Hunting
Strata DK systems provide station hunting such that any station can hunt to any other station.
There is no limit to the combinations of hunting or the number of stations that can hunt to
other stations. Strata users find many call coverage applications for hunting. The Norstar
systems do not provide this feature.

Strata DK Advantages Over Norstar
6Strata DK 12/99
Call Forward
The Norstar offers External Call Forwarding as an option, but it does not have remote change
capabilities. Since employees outside the office must often change their external forwarding
destination, external forwarding becomes very cumbersome to use without the ability to
change the destination remotely. The Strata DK provides both external call forward and
remote change capabilities as a standard feature. This increases its usability and value. Strata
DK also provides call forward busy/no answer mode, which the Norstar lacks.
Conference
Conference calling capabilities are limited on the Norstar. Three party maximum allows two
internal/1 external or two external/1 internal combinations. Strata DK systems provide four
party conference. In addition, Strata DK provides amplified conference interface, which the
Norstar lacks. Amplified conference compensates for volume loss to outside parties through
the public network.
Memory Protection
Memory in the Norstar is protected from commercial power loss by a NiCad battery that
provides a 72-hour retention in the KSU. When power is restored, the Norstar KSU downloads
administrative information to the telephones, a process that takes about five minutes. This
restores the system without reprogramming. If the power failure exceeds the 72-hour battery
hold time, the Norstar reverts to its default configuration and must be completely
reprogrammed. The Strata DK’s internal battery will protect memory data and programming
within a powerless system for the life of the battery, approximately six years. Thus,
programming is never lost in a power failure, and no telephone downloading is necessary
when power is restored, providing immediate restoration of telephone service.
Automatic Station Relocation
The Norstar’s automatic set relocation feature allows a moved telephone set to retain its
individual programming and extension number, making telephone moves quick and easy.
However, this feature is limited on the Norstar because it requires relocation of the same type
and model phone to another jack. This means you can’t swap a 20-button phone for an 8-
button model without reprogramming. This same feature in the Strata DK enables you to
relocate any digital phone to any digital station jack. The Strata system will automatically
reassign the station type in programming, even if they are different models. This makes
swapping telephone locations much more flexible and practical to use, especially in
applications where most telephone changes are a result of upgrading to another model.
LCD Feature Prompting
The Norstar LCD provides relatively easy to use feature instructions, but does require a few
steps to initiate. Feature activation is done by pressing the Feature key and then dialing a
feature code. LCD prompting then provides display instructions for required entry. Soft keys
(not available on the Norstar M7100 or M7208 model telephones) allow choices selected by
pressing one of three buttons that change function with each feature display. Strata DK
systems provide better and more automatic LCD feature prompting capabilities. Strata DK
feature prompting does not require manual activation or entry of a feature code. LCD choices
and instructions appear automatically and change according to the calling status you are in.
This makes the use of this function much quicker, easier, and more automatic on Strata DK
systems.

Strata DK Advantages Over Norstar
Strata DK 12/99 7
User Programmable Feature Buttons
Norstar telephones have user programmable buttons enabling individual station users to store
personal speed dial numbers, and assign their buttons to auto dial or features. Strata DK
systems also have this feature, including an additional advantage. User programmable feature
buttons can store functions such as hold, intercom, and conf/trans, as well as feature access
codes, to perform multiple operation at the touch of one button.
Automatic Hold/Release
Automatic Hold is a feature the Norstar provides to prevent lost calls. Strata DK systems also
have this feature. However, in high traffic call situations, Auto Hold is inefficient because call
takers go from one call to the next simply by pressing the ringing CO line key, and Auto Hold
would require them to release the call before going to the next. Auto Hold is programmable by
station on Strata DK systems, to either automatically place the call on hold or automatically
release the call when another button is pressed. This enables each Strata station user to choose
the method most effective for them, providing flexibility unavailable with the Norstar.
Release/Answer
Strata DK systems provide the Release/Answer button as an efficient way to handle multiple
incoming calls. A station user who is talking on a call can release and transfer or disconnect
the active call, and automatically answer a new incoming call with the press of one button.
This is especially useful for heavy traffic call answering applications. Norstar systems do not
provide this useful feature.
Ground Start Lines
The Norstar ICS Compact does not support ground start CO lines that the Strata DK40i
supports. Ground start lines provide better CO line supervision for disconnect signaling than
loop start lines and prevent collision of incoming and outgoing calls. This can be important in
applications using auto attendant and voice mail in which there are lots of hold hang-ups.
Voice Over IP
The Strata DK40i and DK424 systems integrate with the Oki Internet Voice Gateway products
to route both voice and fax traffic through any new or existing data Wide Area Network
(WAN) infrastructure, such as point to point, Frame Relay, a Virtual Private Network (VPN),
or the public Internet. This eliminates the need to maintain separate networks, improves
overall business operation, and produces substantial cost savings. Norstar systems do not
support voice over IP capabilities.
Hospitality Management
The Strata DK40i and DK424 systems integrate with the Toshiba Hospitality Management
Information System, a PC-based solution that provides hotel/motel specific features, front
desk operation, and several property management capabilities. Norstar systems do not support
hospitality features.

Nortel’s Selling Points
8Strata DK 12/99
Nortel’s Selling Points
Every Norstar Telephone Has an LCD
Every Norstar telephone model has an LCD, except the M7100 single line telephone. The
M7208 has eight programmable feature buttons, making it slightly more desirable as a feature
phone. However, its LCD is only a 1 line 16 character display with no soft keys, which
provides much less display information, and is unacceptable to use for feature prompting
compared to the more expensive M7310 and M7324 models. Five Toshiba digital telephone
models are available, with or without a 2 line x 16 character LCD, and a single line digital
telephone is also available.
Centrex Features
The Norstar ICS offers a Centrex feature option to provide easy access to certain Centrex
features. Strata DK systems also provide strong Centrex compatibility through features like
flexible numbering, user programmable feature buttons, flexible flash timing, Centrex ringing
repeat, and delayed ringing, making its operation very efficient in Centrex applications.
Language Choice
The Norstar ICS provides a language choice of English, French, or Spanish on LCD display
information. This is because it is designed by Canadian specifications and Canada is a
bilingual country. Strata systems display information in English only because they were
designed specifically for the U.S. market where foreign language displays are not required.
Auto Day/Night Service Activation
The Norstar ICS has auto day/night service activation to automatically switch the system
between day and night modes by time of day. Strata DK systems must be switched manually
between day and night modes, unless the Toshiba Ultimate Communicator™or PC Attendant
Console is in use to provide this feature. The Strata DK provides night ringing over external
page and night ringing over external page zones, which the Norstar lacks.
Dial Backspace Erase
The Norstar provides the ability to backspace while dialing a number, if an incorrect digit is
noticed by the user before completing the number. This saves the time of redialing the digits,
assuming the user is watching the LCD while dialing to detect the error.
Voice Mail Soft Key Prompting
The Norstar ICS, when used with the Norstar voice mail system, provides LCD prompting and
soft key operation of voice mail features. However, this feature is only available on the two
more expensive M7310 and M7324 models, and not on the more commonly used M7208
telephone. Therefore, it has limited application in most Norstar configurations. Also, voice
mail users typically find the use of keypad commands of frequently used features faster than
LCD soft key choices. Strata DK systems do not provide voice mail soft key prompting as a
standard feature, but can provide similar functionality using the Toshiba Ultimate
Communicator.

Tie-line Coordinated Dialing
The Norstar ICS Modular’s coordinated dialing plan (not available on other Norstar models)
enables a station user to dial stations on another system, connected by Tie lines, the same as if
they were local extensions. This saves the dialing of an extra Tie line access digit, as required
on the Strata DK. However, the Norstar does not provide the Tie line transfer recall feature that
the DK40i and DK424 provides.
System Alarm Indicators
Norstar system alarm message codes are generated to alert the system administrator of certain
system malfunctions. Alarm message codes appear on the LCD of the designated alarm
telephone. The system administrator can then call for service. This is a useful function, but the
user knows when they are experiencing a system problem, even without alarm messages. On
Strata DK systems, service technicians can easily diagnose system problems either on site or
remotely.

Toshiba Strata DK & Nortel Norstar Product Comparison
Product Comparison
14 Strata DK 12/99
1 The Norstar does not have a cost effective battery backup option. An expensive UPS is required for reserve power backup.
2 Norstar DID numbers (not regular DNs) can appear more than once on a DKT and can appear on another telephone, providing
limited multiple DN appearances. No phantom DNs.
3 Norstar can be an end node in a Meridian 1 private network, but cannot network multiple Norstars alone. Supports uniform
dialing plan but no centralized voice mail and no feature transparency.
4 Toshiba Strata DK424 supports partial networking features of coordinated numbering, centralized voice mail, and off-net toll
bypass over a private network through Adtran adjunct equipment. Release link trunk and feature transparency not supported.
5 The Nortel Meridian Option 11C Compact supports maximum 200 ports in 2 cabinets with the General Business configuration
and 400 ports in 3 cabinets with the Hospitality configuration.
6 Nortel announced that the Meridian Option 11C will soon be expanded from 400 ports to 700 ports using dual-port daughter
boards that replace the single-port boards.
