5-8 Issue 9 May 2003

For DEFINITY G2 and System 85, either a barrier code or an authorization code

(see below) can be required before callers can access switch features or trunks.

There is only one 4-digit barrier code for the Remote Access feature. This can be

changed using a feature access code, and is normally assigned by the attendant.

When callers enter the wrong barrier code, the calls are given intercept treatment.

(When no barrier code is entered, the call can be routed to an attendant.) A barrier

code should be used to screen entry into this feature; authorization codes can

then be used to screen outgoing calls on Automatic Alternate Routing (AAR),

Automatic Route Selection (ARS), and World Class Routing (WCR) (G2.2) trunks.

Authorization codes

NOTE:

For all systems, once established, the number of digits (four to seven) in the

authorization code remains fixed unless all codes are removed and

re-entered. All authorization codes used in the system must be the same

length.

For Communication Manager, MultiVantage™ Software, DEFINITY ECS,

DEFINITY G1, G3, and System 75 R1V3, the calling privileges of an authorization

code overrides the privileges established by the barrier code. With remote access

calls, dialing an authorization code overrides the COR set for the barrier code.

Individual users should be assigned unique authorization codes from four to

seven digits (use all seven for maximum security).

Authorization codes serve as a second layer of protection when combined with

barrier codes for the Remote Access feature. When authorization codes are

required, the caller hears a special dial tone (optional) and must then enter a valid

authorization code to access the system.

NOTE:

If a remote access caller is to be restricted from long distance but allowed

other ARS calls (for example, local), then the authorization code COR

should have an appropriately low FRL.

NOTE:

Authorization codes are also recorded by the PBX’s call detail recording

feature (SMDR/CDR), allowing for call verification by the individual assigned

the authorization code. Proper security must be followed to protect any

printed copies of the call records.

1. Authorization codes are standard only in System 85 and DEFINITY G2. They are an option

for System 75 R1V3, DEFINITY G1, and G3, Communication Manager, MultiVantage™

Software, and DEFINITY ECS require the customer to purchase the appropriate right to

use.
