Introduction
How To Use This Chapter
This chapter provides detailed information on the system’s features. The features in this chapterare in alpha-
betical order, like a dictionary, and are subdivided into headings as follows:
❥Description
Read Description to get an overview of the feature.
❥Operation
Refer to this heading for convenient, compact, yet detailed operation charts for using each feature.

Account Codes
10 ◆Features DSX Feature Handbook
Account Codes
Description
Account Codes are user-dialed codes that help categorize and/or restrict outside calls. Account Codes are
from 2-10 digits long, using any combination of the digits 0-9. There are three types of Account Codes:
❥Optional (Unforced Account Codes)
❥Forced Account Codes
❥Verified Account Codes
Optional (Unforced) Account Codes
Optional Account Codes allow a keyset extension user to enter an Account Code while placing an outside
call or any time while on a call. This type of Account Code is optional: the system does not require the user
to enter it. If the keyset user is already talking on an outside call, their conversation continues uninterrupted
while they enter an Account Code.
Single line telephone users can only enter an Account Code while placing their outside call.
Forced Account Codes
Forced Account Codes require an extension user to enter an Account Code every time they place an outside
call. If the user doesn’t enter the code, the system prevents the call. The system can require Forced Account
Codes for all outside calls, or just for toll calls (as determined by Toll Restriction programming). Note that
Forced Account Codes do not pertain to incoming calls.
Verified Account Codes
With Verified Account Codes, the system compares the Account Code the user dials with a list of codes pro-
grammed into the Verified Account Code Table. If the Account Code is in the table, the call goes through
(provided it is not prevented by an extension’s Toll Restriction programming). If the code is not in the table,
the system prevents the call. Verified Account Codes, if enabled, apply only to Forced Account Codes.
Using Account Codes and Speed Dial
To simplify Account Code operation, Personal and System Speed Dial bins can contain Account Codes.
Keep the following in mind when using Speed Dial and Account Codes:
❥The Account Code can be either the first or last entry in the bin, and must be preceded and followed by
the # character. For example, the Account Code 1234 must be entered as #1234#.
❥The Speed Dial bin can contain an Account Code followed by an outside number, or just the Account
Code. The Account Code must be preceded and followed by a # entry. If the bin contains just the
Account Code, the user must be sure to press the bin key before dialing the outside number.
❥If the system has Verified Account Codes enabled, the Account Code entered in the Speed Dial bin must
match an entry in the Verified Account Code Table.
❥If the Speed Dial bin does not contain an Account Code, the user must enter the Account Code manually.
If Forced Account Codes are enabled, the system requires the user to enter the Account Code before it
outdials the stored Speed Dial number.
❥An extension user can preselect a line for a Speed Dial call.
Using Account Codes with Last Number Redial and Save
Last Number Redial and Save do not store Account Codes. This means that the user must manually enter an
Account Code to have it included with a call dialed using Last Number Redial and Save. If Forced Account
Codes are enabled, the system requires the user to enter the Account Code before it outdials the stored num-
ber saved by Last Number Redial or Save.
An extension user can preselect a line for a Last Number Redial or Save call.
Use Account codes to categorize and/or restrict outside calls.
