NXDS0
Contiguous
Specifies whether to hunt contiguous NXDS0 channels. This field only appears if 
y is entered in NXDS0. The hunt algorithm to satisfy an NXDS0 call is as follows:
Remote Access
The Remote Access screen is used to implement the Remote Access feature. 
Remote Access permits a caller located outside the system to access the system 
through the public or private network and then use the features and services of the 
system.
Remote Access users can dial into the system using central office (CO), Foreign 
Exchange (FX), Wide Area Telecommunications trunks (WATS), and Integrated 
Services Digital Network Primary Rate Interface (ISDN-PRI) trunks. In addition, 
a dedicated Remote Access Direct Inward Dialing number can be provided.
Valid entries Usage
y/n
Enter y to specify the ISDN information transfer rate for 1920 
Kbps data, which includes 30 B-channels. When a PE is 
administered to support H12, the hunt algorithm to satisfy a 
call requiring 1920 Kbps of bandwidth uses a fixed allocation 
scheme.
Valid entries Usage
y/n
Enter y to specify the NXDS0 multi-rate service.
Valid entries Usage
y
 Enter y to specify the “floating” scheme. NXDS0 calls are 
placed on a contiguous group of B-channels large enough to 
satisfy the requested bandwidth without constraint on the 
starting channel (no fixed starting point trunk).
H0 and NXDS0 “floating” scheme cannot both be 
y.
n Enter n to specify the “flexible” scheme. NXDS0 calls are 
placed on any set of B-channels on the same facility as long as 
the requested bandwidth is satisfied. There are no constraints, 
such as contiguity of B-channels or fixed starting points.

!SECURITY ALERT:
Lucent Technologies designed the Remote Access feature incorporated in 
this product that, when properly administered by the customer, enables the 
customer to minimize the ability of unauthorized persons to gain access to 
the network. It is the customer’s responsibility to take the appropriate steps 
to properly implement the features, evaluate and administer the various 
restriction levels, protect access codes and distribute them only to 
individuals who have been advised of the sensitive nature of the access 
information. Each authorized user should be instructed concerning the 
proper use and handling of access codes.
In rare instances, unauthorized individuals make connections to the 
telecommunications network through use of remote access features. In such 
an event, applicable tariffs require the customer pay all network charges for 
traffic. Lucent Technologies cannot be responsible for such charges, and will 
not make any allowance or give any credit for charges that result from 
unauthorized access.
To ensure the security of your system, consider the following:
nMake all remote access facilities unlisted directory telephone numbers.
nRequire users to enter a Barrier Code of at least seven random digits AND 
an Authorization Code of at least 13 random digits to make network calls.
nMake Authorization Codes nonconsecutive (random) and change them, at 
least, quarterly.
nDeactivate Authorization Codes immediately if the user leaves the 
company or changes assignments.
nAssign the minimum level of calling permissions required to each 
Authorization Code.
nBlock off-hours and weekend remote access calling, when possible. Use 
Alternative Facility Restriction Levels, if available.
nUse a voice recording, warble tone, or no tone and avoid use of a dial tone 
as a prompt when the remote access unit answers.
nAssign the lowest possible FRL to only allow internal switch calls.
As an additional step to ensure System security, you can permanently disable the 
Remote Access feature if you do not intend to use it now or in the future. If you do 
decide to permanently disable the feature, it will require Lucent Services 
intervention to activate the feature again.

!CAUTION:
Your attempt to disable the Remote Access feature will be lost if the switch is 
rebooted without saving translations. Therefore, execute a “save 
translation” command after permanently disabling the Remote Access 
feature.
To assist you in maintaining the security of your system, DEFINITY ECS 
provides the status remote access command, which provides status and 
information on each remote access barrier code and on the remote access feature. 
A sample Status Remote Access screen follows the Remote Access screen.

Remote Access Extension
The remote access extension is used as if it was a DID extension. Only one DID 
extension can be assigned as the remote access extension. Calls to that number are 
treated the same as calls on the remote access trunk.
When a trunk group is dedicated to Remote Access, the remote access extension 
number is administered on the trunk group’s incoming destination field.
Barrier Code Length
Assign a barrier code length of 7 to provide maximum security.

each trunk that supports the Remote Access feature. You

When you use an authorization code in conjunction with a barrier codes it 
increases the security of the Remote Access feature.
Remote Access Dial Tone
Set this field to 
n for maximum security. This field appears when the 
Authorization Code Required field is set to y.
Barrier Code
You must assign a barrier code that conforms to the number entered in the Barrier 
Code Length field. You may enter up to 10 barrier codes per system. Duplicate 
entries are not allowed. You must keep your own records regarding the 
distribution of these barrier codes to your personnel.
COR
Assign the most restrictive class of restriction (COR), that provides only the level 
of service required, to provide the maximum security.
Valid entries Usage
y/n
Enter y to require an authorization code be dialed by Remote 
Access users to access the system’s Remote Access facilities.
Valid entries Usage
y/n
Enter n so that there is no Remote Access Dial Tone prompt.

COS
Assign the most restrictive class of service (COS), that provides only the level of 
service required to provide the maximum security.
Expiration Date
Assign an expiration date based on the expected length of time the barrier code 
will be needed. If it is expected the barrier code is to be used for a 2-week period, 
assign a date two weeks from the current date. If the Expiration Date is assigned, a 
warning message is displayed on the system copyright screen seven days prior to 
the expiration date. The system administer can modify the expiration date to 
extend the time interval if needed.
No. of Calls
The Expiration Date and No. of Calls fields can be used independently or in 
conjunction to provide the maximum security. If both the Expiration Date and No. 
of Calls fields are assigned, the corresponding barrier code expires when the first 
of these criteria is satisfied.
Calls Used
This display-only field shows the number of calls placed using the corresponding 
barrier code. This field is incremented each time a barrier code is successfully 
used to access the Remote Access feature. A usage that exceeds the expected rate 
indicates improper use.

Route Pattern
The Route Pattern screen defines the route patterns used by your switch. Each 
route pattern contains a list of trunk groups that can be used to route the call. The 
maximum number of route patterns and trunk groups allowed depends on the 
configuration and memory available in your system.
Use this screen to insert or delete digits so AAR or ARS calls route over different 
trunk groups. You can convert an AAR number into an international number, and 
insert an area code in an AAR number to convert an on-network number to a 
public network number. Also, when a call directly accesses a local central office 
(CO), if the long-distance carrier provided by your CO is not available, your 
switch can insert the dial access code for an alternative carrier into the digit string.
