Security Alert:

As a customer of a new telephone system, you should be aware that there exists an increasing problem of telephone toll fraud. Telephone toll fraud can occur in many forms, despite the numerous efforts of telephone companies and telephone equipment manufacturers to control it. Some individuals use electronic devices to prevent or falsify records of these calls. Others charge calls to someone else’s number by illegally using lost or stolen calling cards, billing innocent parties, clipping on to someone else’s line, and breaking into someone else’s telephone equipment physically or electronically. In certain instances, unauthorized individuals make connections to the telephone network through the use of remote access features.

The Remote Access feature of your system, if you choose to use it, permits offpremises callers to access the system from a remote telephone by using an 800 number or a 7- or 10-digit telephone number. The system returns an acknowledgment signaling the user to key in his or her barrier code, which is selected and administered by the system manager. After the barrier code is accepted, the system returns dial tone to the user. If you do not program specific restrictions, the user will be able to place any call normally dialed from a telephone associated with the system. Such an off-premises network call is originated at and will be billed from the system location.

4–262 Programming Procedures


The Remote Access feature helps the customer, through proper administration, to minimize the ability of unauthorized persons to gain access to the network.

Most commonly, phone numbers and codes are compromised when overheard in a public location, through theft of a wallet or purse containing access information, or through carelessness (writing codes on a piece of paper and improperly discarding it). Additionally, hackers may use a computer to dial an access code and then publish the information to other hackers. Enormous charges can be run up quickly. 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 access codes only to individuals who have been fully advised of the sensitive nature of the access information.

Common carriers are required by law to collect their tariffed charges. While these charges are fraudulent charges made by persons with criminal intent, applicable tariffs state that the customer of record is responsible for payment of all long-distance or other network charges. AT&T cannot be responsible for such charges and will not make any allowance or give any credit for charges that result from unauthorized access.

To minimize the risk of unauthorized access to your communications system follow these basic rules:

■ Use a nonpublished remote access number.

■ Assign barrier codes randomly to users on a need-to-have basis, keeping a log of ALL authorized users and assigning one code to one person.

■ Use random sequence barrier codes, which are less likely to be broken.

■ Deactivate all unassigned codes promptly.

■ Ensure that remote access users are aware of their responsibility to keep the telephone number and any barrier codes secure.

■ When possible, restrict the off-network capability of off-premises callers using the Call Restrictions and Disallowed List capabilities.

■ When possible, block out-of-hours calling.

■ Frequently monitor system call detail reports for quicker detection of any unauthorized or abnormal calling patterns.

■ Limit remote call forward to persons on a need-to-have basis.

■ Always use the longest length password allowed on the system.

■ Passwords should consist of a random, non-repetitive, hard-to-guess sequence of digits.

Programming Procedures 4–263


Remote Access Trunk Assignment

Use this procedure to assign or remove the trunks used for remote access. You can also use this procedure to specify whether the Remote Access feature is dedicated (always used for remote access) or shared (used for remote access only when Night Service is activated).

Trunks used for dedicated remote access must not be assigned to ring into a calling group or the QCC queue (Hybrid/PBX mode only).

In Hybrid/PBX mode, if a trunk assigned to ring into the QCC queue is also used for shared remote access, perform the procedure below before you perform the

“QCC Operator to Receive Calls” procedure.

NOTE:

A loop start line/trunk must be programmed for Reliable Disconnect if it is to be

used for remote access (see “Disconnect Signaling Reliablility”).

Remote Access Without Barrier Codes

Use this procedure to change the class of restriction for one of the following:

■ All non-tie lines/trunks

■ All tie trunks and DID trunks with Remote Access

■ DID remote access code

!

Security Alert:

Your system will be highly susceptible to toll fraud if you activate the

Remote Access feature without barrier codes. AT&T does not recommend doing this.

NOTE:

If barrier code requirements have been established for remote access users, use “Remote Access with Barrier Codes” and not this procedure.

The class of restriction assigned may be one of the following:

■ Restriction.

Determines whether remote access users can make local and/or toll calls and includes the following settings:

Unrestricted

Toll restricted

Outward restricted

■ ARS Facility Restriction Level (Hybrid/PBX only). Allows or disallows use of outgoing trunks by assigning a facility restriction level from 0 through 6. The FRL ranges from 0 (most restrictive) to 6 (least restrictive).

The FRL value assigned here is the opposite of the FRL value assigned to the ARS route, where a value of 0 is the least restrictive and a value of 6 is the most restrictive.

■ Allowed Lists Assignment.

Assigns Allowed Lists and is used when remote access users are restricted from making local or toll calls.

■ Disallowed Lists Assignment.

Assigns Disallowed Lists and is used when remote access users are not restricted from making local or toll calls.

A maximum of eight Allowed or Disallowed Lists can be assigned to lines/trunks.

Class of restriction settings are assigned either to all non-tie trunks or to all tie trunks and DID trunks. They cannot be assigned to each trunk on an individual basis.

Remote Access Barrier Codes

Use this procedure to establish or remove barrier code requirements as well as to establish or remove the barrier codes themselves.

Barrier codes are security passwords that restrict users from making unauthorized remote access calls on tie and non-tie lines and trunks. Callers are allowed three attempts per call to enter the correct remote access barrier code.

If the caller enters an incorrect barrier code or times out during code entry, the caller hears the retry tone. The caller can erase an entered code by dialing **

(two asterisks). Code erasure is counted as one of the three permitted attempts.

After three unsuccessful attempts, the caller hears a reorder tone and the call is disconnected. If this happens, the SMDR will contain sixteen 0’s in the Account

Code field to flag the three failed attempts.

A maximum of 16 barrier codes are allowed for all lines/trunks. Each of the 16 barrier codes may be programmed with its own class of restriction (COR).

The systemwide barrier code length can range from a minimum of 4 characters to a maximum of 11 characters. The default length is 7. If you enter a length that is less than 4 or greater than 11, the entry is erased and the previous entry displays on the screen. When the barrier code length is changed, all barrier codes are erased and must be reassigned. If the barrier code length is changed and barrier codes are not reassigned, users can dial into remote access trunks and enter a barrier code, but will be denied access into the remote access trunks no matter what code is entered.

!

Security Alert:

■ Always use the longest length barrier code allowed on the system.

■ Barrier codes should consist of a random, non-repetitive, hard-toguess sequence of digits.

The time and date of the most recent change made to the systemwide barrier code length is shown during the system programming procedure as well as on the Remote Access DISA Information report. The SMDR record for incoming remote access trunks includes the barrier code IDs established in this procedure.



Use numbers 0 through 9 and the asterisk (*) to enter the barrier codes. The codes cannot start with an asterisk and cannot contain two consecutive asterisks. (The use of two consecutive asterisks is reserved for users to erase an incorrect barrier code entry.)

See “Remote Access with Barrier Codes: Class of Restriction” to allow or deny

use of system features for each barrier code assigned.

Remote Access with Barrier Codes

Use this procedure to change the class of restriction for individual remote access barrier codes. The class of restriction assigned to each barrier code allows or denies the use of the following system features:

■ Restriction.

Determines whether remote access users can make local and/or toll calls, and includes the following settings:

Unrestricted

Toll restricted

Outward restricted

■ ARS Facility Restriction Level (Hybrid/PBX only). Allows or restricts use of outgoing trunks by assigning a facility restriction level (FRL) from 0 through 6. The FRL ranges from 0 (most restrictive) to 6 (least restrictive).

The FRL value assigned here is the opposite of the FRL value assigned to the ARS route, where a value of 0 is the least restrictive, and a value of 6 is the most restrictive.

■ Allowed Lists Assignment.

Assigns Allowed Lists and is used when remote access users are restricted from making local or toll calls.

■ Disallowed Lists Assignment.

Assigns Disallowed Lists and is used when remote access users are not restricted from making local or toll calls.



A maximum of eight Allowed or Disallowed Lists can be assigned to each barrier code. Class of restriction settings apply to individual barrier codes.

NOTE:

If barrier code requirements have not been established or have been removed

for remote access users, do not use this procedure. See “Remote Access

Without Barrier Codes.”
