Remote system access
The remote access feature allows callers elsewhere on the public network 
to access a Norstar system directly without going through an attendant. 
Once in the system, the remote user can use some of the system resources. 
The remote access must be enabled in programming before callers can use 
it.
Norstar Compact ICS systems support remote system access on auto-
answer loop start trunks and can require the remote caller to enter a 
(COS) password for direct inward system access (DISA).
The system resources —dialing capabilities, line pool access and feature 
access —  that a remote user may access depends on the Class of Service 
(COS) assigned to them. See the description of COS on page 52 for more 
details.
To use features on a Norstar system remotely, press 
¥ followed by the 
feature code. Even if you are calling from another Norstar system, press 
¥ 
instead of 
².
Remote access on loop start trunks
Loop start trunks provide remote access to the Norstar system from the 
public network and must be configured as auto-answer in Lines 
programming to provide remote system access. 
A loop start trunk must have disconnect supervision enabled if it is to 
operate in auto-answer mode. 
When a caller dials into the system on a line that has auto-answer, the 
system answers with system dial tone and no COS password is required. In 
this case, control over the system capabilities available to the caller is 
provided only by the restriction filters assigned to the line.
When a caller dials in on a line that has auto-answer with DISA, the system 
answers with stuttered dial tone. This is the prompt to the caller to enter a 
COS password, which determines which system capabilities are available 
to the caller.

Security
Programming provides several ways of protecting your Norstar system 
from unauthorized access or use.
Class of Service
Class of Service (COS) refers to the capabilities that Norstar provides to 
users who access the system from the public or a private network. 
The COS includes:
filters that restrict dialing on the line
an access package, which defines the set of line pools that may be 
accessed and whether or not the user has access to the paging feature.
The COS that is applied to an incoming remote access call is determined 
by:
the filters that you apply to the incoming trunk
the COS password that the caller used to gain access to the Norstar 
system.
In cases where DISA is not automatically applied to incoming calls, the 
remote caller can change the COS by dialing the DISA DN and entering a 
COS password.
To program COS passwords, see COS pswds on page 196 in this guide.
Restriction filters
Restriction filters can be used to restrict the numbers that may be dialed on 
any external line within the Norstar system. Up to 100 restriction filters can 
be created for the system. A restriction filter consists of up to 48 restrictions 
and their associated overrides. 
						

							Networking features / 53
P0603539  02Compact ICS 6.1 Installer Guide
To restrict dialing within the system, you can apply restriction filters to:
outgoing external lines (as line restrictions)
telephones (as set restrictions)
external lines on specific telephones (as line/set  restrictions)
Restriction filters can also be specified in Restrictions service for times 
when the system is operating according to a schedule. Refer to the 
description in Services on page 174 for more details.
Calling out
Dialed digits must pass both the line restrictions and the set restrictions. 
The line per set (line/set) restriction overrides the line restriction and set 
restriction.
In this diagram, a caller using line 001 could only dial long-distance 
numbers to area codes 212 and 718. A caller using line 003 could not dial 
any long-distance numbers. A caller using line 005 could dial long-distance 
numbers to area codes 212, 718, and 415.

Calling in
In this case, dialed digits must pass both the remote restriction and the line 
restriction. A remote caller can override these filters by dialing the  
DISA DN and entering a COS password. 
For restriction filter programming instructions, see Restrn filters on page 
170 in this guide.
Direct inward system access (DISA)
To control access from the public network, configure auto-answer trunks 
to answer with DISA. Remote callers hear a stuttered dial tone and  must 
then enter a COS password that determines what they are allowed to do in 
the system.
Auto-answer loop start trunks are configured to answer with DISA by 
default. For DISA programming instructions, see Trunk/Line data under 
Lines on page 161 in this guide.
Tip - To restrict dialing from outside the system (once 
a caller gains remote access), apply restriction filters to 
incoming external lines (as remote restrictions).

Transparent dialing plan
The Norstar system has a routing feature that allows you to set up a 
transparent or coordinated dialing plan with other systems in the public 
network. The goal is to have a network-wide dialing plan where all 
telephone numbers are unique and of a uniform length.
Dialing plans are typically used with a network of systems with a three to 
seven-digit dialing access between them.
Any programming for routing should be carefully planned using the tables 
supplied with the Programming Record. The settings for routing and 
destination codes are fully explained under Routing service on page 179. 
This section deals with applying the programming in network situations. 
Dialing plan using public lines
The following illustrations show the Programming Record for a Toronto 
system in a network of three offices: Toronto, Halifax and Vancouver. 
Without routing, a Norstar user in Toronto would have to select a line pool 
and dial 1-902-585-3027 to reach extension 27 in Halifax (902). By 
creating a destination code of 30 and creating a route that uses the proper 
line pool and DialOut, the user simply dials 3027. The same feature is 
available for Vancouver (604).
In the DialOut, P stands for pause, a host system signaling option. Press 
²à¡ to insert a 1.5-second pause in the dialing string. See the System 
Coordinator Guide for information about other signals.

Note that, in this case, only the Normal schedule is being used.
Destination code numbering in a network
Because the system checks the initial digits of a call against the routing 
tables, each type of internal or external call must begin with a unique 
pattern of digits. The following table gives a sample plan for how initial 
digits are assigned in a network of systems with three-digit intercom 
numbers.
Leading DigitsUse
221-253Intercom calls
Tip - When programming a button to dial a 
Network number automatically (autodial), network 
calls must be treated as external numbers, even though 
they resemble internal extension numbers.
Routes generally define the path between the Norstar 
system and another switch in the network, not other 
individual telephones on that switch.

ISDN applications
ISDN terminal equipment delivers a wide range of powerful business 
applications:
Video conferencing and video telephony
Video conferencing offers instant visual and audio contact between distant 
parties using either studio-based or desktop ISDN terminals.
Desktop conferencing
ISDN allows computer users in distant locations to share and edit any 
image, data or text file on their own computer screens while they discuss 
the information.
File transfer
The ISDN network allows you to transfer files containing data, text, 
images, data, or audio clips, faster and cheaper than with a conventional 
modem.

Telecommuting
Convenient retrieval, processing and storage of files is possible for the 
employee working at home by using ISDN lines to give high-speed access 
to information resources at the office.
Group 4 fax
ISDN fax applications save money by increasing both transmission speed 
and the quality of resolution.
Remote LAN access
ISDN provides an affordable and fast means for employees at remote sites, 
such as at home or in branch offices, to access local area networks (LANs).
Leased line backup
Essential backup for leased lines can be provided using ISDN as required, 
rather than duplicating costly permanent leased lines.
LAN to LAN bridging
Local area network (LAN) bridge/routers allow flexible interconnection 
between LANs using ISDN, with charges only incurred when information 
is actually transmitted.
Internet and database access
The fast call set up and high bandwidth of ISDN are ideal for accessing 
information services such as the Internet and databases.
