Remote Access

Last Updated : Oct 29, 2012 |

Implements 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.

Security alert:

The Remote Access feature, when properly administered, 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. Avaya will not be responsible for such charges, and will not make any allowance or give any credit for charges that result from unauthorized access.

Example command: change remote-access

Authorization Code Required

If enabled, requires an authorization code be dialed by Remote Access users to access the system’s Remote Access facilities. The use of an authorization code in conjunction with a barrier code increases the security of the Remote Access feature.

Barrier Code

The number users must dial to use Remote Access. Can be used with an authorization code. Accepts a four- to seven-digit number in any combination of digits. Must conform to the administered Barrier Code Length. The none value is required if a Barrier Code Length is not administered.

Barrier Code Length

Valid Entry

Usage

4 to 7

blank

The length of the barrier code. A barrier code length of 7 provides maximum security.

Calls Used

The number of calls placed using the corresponding barrier code. A usage that exceeds the expected rate indicates improper use.

COR

Valid Entry

Usage

0 to 995

The number of the class of restriction (COR) associated with the barrier code. To provide maximum security, assign the most restrictive COR that provides only the level of service required.

COS

Valid Entry

Usage

0 to 15

The number of the class of service (COS) associated with the barrier code. To provide maximum security, assign the most restrictive COS that provides only the level of service required.

Disable Following a Security Violation

Available only if SVN Authorization Code Violation Notification is enabled for the system.

Valid Entry

Usage

y

Disables the Remote Access feature following detection of a Remote Access security violation. The system administrator can re-enable Remote Access using the enable remote-access command.

n

Enables the Remote Access feature following detection of a Remote Access security violation.

Expiration Date

The date the barrier code expires. Assign an expiration date based on the expected length of time the barrier code is needed. For example, if the barrier code is expected to be used for a two-week period, assign a date two weeks from the current date. If both an Expiration Date and No. of Calls are assigned, the corresponding barrier code expires when the first of these criteria is satisfied.

No. of Calls

Valid Entry

Usage

1 to 9999

blank

The number of Remote Access calls that can be placed using the associated barrier code. If both an Expiration Date and No. of Calls are assigned, the corresponding barrier code expires when the first of these criteria is satisfied.

Permanently Disable

If enabled, permanently blocks remote access to the administration interface. Reactivation of remote access to the interface requires the intervention of Avaya Services.

Remote Access Dial Tone

Enables or disables the user hearing dial tone as a prompt for entering the authorization code. Disabling this feature provides maximum security. Available only if Authorization Codes are required for Remote Access.

Remote Access Extension

The extension assigned to handle Remote Access calls. 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 as the trunk group’s incoming destination.

A Vector Directory Number (VDN) extension cannot be used as the remote access extension.

Can be blank if no barrier codes are administered.

TN

Use this field to specify a tenant number. You can enter a value from 1 to 250.
