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.

Security
Programming provides several ways of protecting your Norstar system 
from unauthorized access or use.
Class of Service

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...

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 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...

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...

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.
