Modular DR5 Installer Guide

Norstar can now be part of a corporate telecommunications
network. You can connect Norstar to an existing private network,
or to other Norstar systems to form a Norstar network.
This chapter explains:
0
how Norstar components behave in a network,
0
how they benefit your business, and
0
how you can configure Norstar to achieve those benefits.
The Big Picture
Norstar uses enhanced trunking to join other Norstar or customer
equipment in a private network. Authorized users can also
access tie-lines, Central Office lines, and Norstar features from
outside the Norstar system.

Norstar as an OPX
Norstar can be used as an off premise extention (OPX) from a
PBX. In order to support this application, the OPX lines must be
engineered not to exceed 7 dB total loop loss from the serving
central office to the demarcation point at the Norstar KSU.

Modular DR5 Installer Guide

2 / Networking with Norstar
Bits and pieces
The trunks and lines that Norstar uses make network access
possible. Target lines concentrate incoming calls on fewer trunks,
and three types of trunks provide the network access:
l
E&M trunks handle incoming and outgoing traffic between
the Norstar system and the private network.
0
DID trunks route incoming calls from the public network
directly to telephones within Norstar, without an attendant.
l
loop start trunks handle incoming and outgoing calls between
Norstar and the public network.
Benefits
Security
Norstar provides the security that expanded access demands.
You can:
0
control remote access to tie-lines, Centrat Office lines, and
system features by setting up a specific Class of Service for
each type of caller,
l
restrict outgoing calls to certain telephone numbers or area
codes by applying dialing filters to lines and telephones, and
a
screen remote callers by configuring trunks to answer with
DISA, a system response that requires callers to enter a valid
password.
Unified dialing plan
When you link a number of Norstar systems into a network, you
can configure them so that the length of Directory Numbers
(DNs), the line pools, and the line pool access codes are
consistent from one system to the next.
Call handling capabilities
In the Norstar system, the concentrated environment supports
call handling features on up to 184 lines, of which 80 are physical
trunks and 104 are target (virtual) lines.

4 / Bits and Pieces
Bits and pieces
To understand the capabilities that are described later in this
chapter, you need to know how the trunks and lines behave in
the Norstar system.
A trunk is a physical connection between the Norstar system and
the outside world. A line is a flexible communication path
between a Norstar user and the outside world. This allows a
one-to-many relationship between trunks and lines.
What this means is that one trunk does not have to represent
one line, but can represent several lines. You achieve this in two
ways:
1. Auto-answer trunks - If you want one trunk to serve many
lines, you configure it as Auto-answer. The Norstar system
answers calls and maps incoming digits onto numbers that
you define in programming. The numbers can access the
system, so that callers can then use selected features or call
out to another destination (calling through the system). The
numbers can also access target lines that appear on one or
more Norstar telephones.
2. Target lines - incoming calls on one trunk can map onto a
number of different target lines. These are virtual lines that
can appear on a Norstar telephone like any other line. They
are incoming lines only, and cannot be selected for outgoing
calls. They are identified to the system by their number. Any
line with a number from 081 to 184 is a target line.
Of course, you can still have a one-to-one relationship between a
trunk and a line. In this case, you configure the trunk as
manual-answer.
You can read more on target lines in the Programming chapter.
To learn more about the types of trunks and the important
differences between auto-answer and manual-answer trunks,
read on.
Modular DR5 Installer Guide

Bits and Pieces / 5
Loop start trunks
Loop start trunks give you incoming and outgoing access to the
public network. However, you would typically configure your
system with loop start trunks for outgoing calls and DID trunks for
incoming calls. Loop start trunks can be configured as
manual-answer or auto-answer.
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, you
hear a stuttered dial tone if the trunk is configured to answer with
DISA. Then you must use a DTMF telephone to enter a 6-digit
Class of Service password.
When a call comes in on an auto-answer loop start trunk, you
hear the system dial tone if the trunk does not have DISA, or if
the Class of Service password is valid. Use a DTMF telephone to
enter a target line number, the DISA DN, a line pool access
code, or a remote feature code.
To place an outgoing call, select a loop start line by dialing a line
pool access code, pressing a line button on the telephone, or
pressing a memory button that has been programmed with a line
pool access, code.
Configuration ‘requirements
You need one Loop Start Trunk Cartridge or Cl Trunk Cartridge
for every four trunks beyond the eight that come with the Key
Service Unit. If you wish to configure your loop start lines as
auto-answer, the lines must have disconnect supervision. You
will also need one E&M/DISA Trunk Cartridge for every two loop
start lines that you configure as auto-answer. An auto-answer
loop start trunk can give you the same kind of direct inward
dialing function as a DID trunk, but you will require E&M/DISA
Trunk Cartridges to receive the incoming digits from the Central
Office.
Modular DR5 installer Guide

6 / Bits and Pieces
You may configure a loop start line as the Prime line for a Norstar
telephone.
E&M trunks
An E&M trunk gives incoming and outgoing tie-line access from
other systems in the private network to the Norstar system. E&M
trunks can be configured as manual-answer or auto-answer.

Modular DR5 Installer Guide

Bits and Pieces / 7
When a call comes in on an auto-answer E&M trunk, you hear a
stuttered dial tone if the trunk is configured to answer with DISA.
Then you must use a DTMF telephone to enter a 6-digit Class of
Service password.
When a call that comes in on an auto-answer E&M Trunk, you
hear the system dial tone if the trunk does not have DISA, or if
the password is valid. Use a DTMF telephone to enter a target
line number, the DISA DN (the number that will call for a Class of
Service password), a line pool access code, or a remote feature
code.
When a call comes in on an auto-answer E&M trunk from an
intelligent network, the Norstar system answers the call and
interprets the incoming digits:
l
If the digits map onto a target line, Norstar routes the call to
all Norstar devices with an appearance of that line.
0
If the digits map onto the DISA DN, you hear a stuttered dial
tone, and must use a DTMF telephone to enter a valid Class
of Service password to get the system dial tone.
0
If the digits map onto the Auto DN (the number for direct
system access), you hear the system dial tone, and can use
a DTMF telephone to enter a target line number, the DISA
DN, a line pool access code, or a remote feature code.
To place an outgoing call, select an E&M trunk by dialing a line
pool access code, pressing a line button on the telephone, or
pressing a memory button that has been programmed with a line
pool access code.
Configurationrequirements
In your configuration, one E&M/DISA Trunk Cartridge is required
for every two E&M trunks. One E&M/DISA Trunk Cartridge is
also required for every two DTMF receivers required for DISA on
loop start trunks.
You may configure an E&M trunk as the Prime line for a Norstar
telephone.
Modular DR5 Installer Guide

8 / Bits and Pieces
DID trunks
DID trunks give you direct inward dialing (DID) from the public
network to the Norstar system. A typical application of these
trunks is to map incoming digits onto target line appearances
within the Norstar system. DID trunks can operate only as
auto-answer trunks.

Configurationrequirements
You need one DID trunk cartridge for every four DID trunks. Each
DID Trunk Cartridge has four DID trunks and four DTMF
receivers dedicated to those trunks.
You cannot configure a DID trunk as the Prime line for a Norstar
telephone.

10 / Benefits
Benefits
Security
In the Capabilities section of Administration programming, there
are several ways of protecting your Norstar system from
unauthorized access.
Class of Service
Class of Service refers to the capabilities that Norstar provides to
users who access the system from the public or private network.
The Class of Service includes:
l filters that restrict dialing on the line, and
0
an access package, which defines the set of line pools that
may be accessed and whether or not the user has access to
the paging feature.
The Class of Service that is applied to an incoming
remote-access call is determined by:
0
the filters that you apply to the incoming trunk, or by
0
the Class of Service password that the caller used to gain
access to the Norstar system.
In cases where DISA is not applied to incoming calls, the remote
caller can change the Class of Service by dialing the DISA DN
and entering a Class of Service password.
To program Class of Service passwords, see Administration in
the Programming chapter.
Dialingfilters
You can use dialing filters to restrict the numbers that may be
dialed on any external line within your Norstar system. You may
specify up to 100 dialing filters for the system. A dialing filter
consists of up to 48 restrictions and their associated exceptions.
Modular DR5 Installer Guide

Benefits / 11
Dialing within the system
To restrict dialing within the system, you can apply dialing filters
to outgoing external lines (as line filters), to telephones (as set
filters), and to external lines on specific telephones (as line per
set filters).

Dialed digits must pass, both the line filter and the set filter. The
line per set filter overrides the line filter and set filter.
In this diagram, a caller using line 1 could only dial long-distance
numbers to area codes 212 and 718. A caller using line 3 could
not dial any long-distance numbers. A caller using line 5 could
dial long-distance numbers to area codes 212, 718, and 415.
/Vote: Set filters have no effect on the numbers that are dialed
on an E&M trunk.
Modular DR5 Installer Guide

12 / Benefits
Dialing outside the system
To restrict dialing outside the system (once a caller gains remote
access), you can apply dialing filters to incoming external lines
(as remote filters).
Remote

Filter
In this case, dialed digits must pass both the remote filter and the
line filter. A remote caller can override these filters by dialing the
DISA DN and entering a Class of Service password.
For programming instructions, see the Programming chapter of
this Installer Guide.
Direct inward system access (DISA)
To control access from the public or private network, you can
configure auto-answer trunks to answer with DISA. Remote
callers hear a stuttered dial tone and must then enter a Class of
Service password that determines what they are allowed to do in
the system.
Auto-answer loop start and E&M trunks are configured to answer
with DISA by default.
Note;’ You must have one E&M/DISA Trunk Cartridge for every
two auto-answer loop start trunks.
Modular DR5 Installer Guide

Benefits / 13
DID trunks cannot be configured to answer with DISA. If you
want incoming DID calls to be answered with DISA, configure the
system with a DISA DN. incoming DID calls that map onto the
DISA DN are then routed to a line that has DISA.
For programming instructions, see the Programming chapter of
this Installer Guide.
Unified dialing plan
The Norstar system does not support a coordinated dialing plan
for other systems in the network. However, if you are configuring
more than one Nor-star system in your network, you can make
access between the systems much easier with a unified dialing
plan.
DirectoryNumbers
Make sure that the length of your DNs is the same for all the
Norstar systems.
Line pools
If the Norstar systems are close to each other geographically,
you can conserve resources by not duplicating access. For
example, system A has a line pool to New York, System B has a
line pool to Los Angeles, and system C has a line pool to Dallas.
A Norstar user in system A calls system C to get the line pool to
Dallas.
Line pool access codes
To simplify access between Norstar systems, all line pools that
go to the same destination should have the same line pool
access code. For example, system A and system B both have a
line pool to London. You can configure both systems with the
same line pool access code for the Nashville line pool.
Modular DR5 Installer Guide

14 / Benefits
Unified dialing plan among four systems
A dialing plan similar to the one in the following figure will let you
create a company directory that includes the line pool access
codes.
Netwk #: 5234
Internal #: 234
Netwk #: 6334
Norstar System A Norstar System B
E&M E&M
Norstar System D Norstar
System C
’ Netwk #: 8534
Internal #: 534 Internal
#: 434
For instance, the person on System A at telephone 234 can
select an Intercom button and dial 7434.
This means that telephone 234 has dialed the line pool access
code of the trunk to System C, and will receive the dial tone of
System C. The digits 434 then map to the Received number 434,
and ring telephone 434 with an appearance of the associated
target line.
