KEEP THE SOFTWARE UP-TO-DATE WITH THE LATEST DATA.
TRS checks are performed for all calls made by:
The PBX can also be programmed to perform a TRS check for numbers that contain non-
digits (  or #). By default, the PBX ignores (No Check) any non-digits that are dialed, 
which is useful in preventing unauthorized calls which could possibly be made using 
certain telephone company exchanges.
TRS can also be programmed to check digits that are dialed after External Feature 
Access, such as when trying to transfer a call to an outside par ty. (  1.10.6 External 
Feature Access (EFA))
Host PBX Access Code/Special Carrier Access Code
TRS checks can be carried out on telephone numbers dialed using a Host PBX Access 
code (  1.5.4.6 Host PBX Access Code (Access Code to the Telephone Company from 
a Host PBX)) or Special Carrier Access code (  1.5.4.7 Special Carrier Access Code).
ARS
If ARS is applied to a dialed number, TRS will check the user-dialed number, not the 
modified number produced by ARS. You do not need to program ARS-modified numbers 
in any of the TRS Tables. Additionally, when using ARS, TRS will ignore the Host PBX 
Access code or Special Carrier Access code.
Dialing Digit Restriction during Conversation 
TRS can also limit the number of digits which may be dialed by an extension user while 
the user is engaged on a received CO line call. If the number of dialed digits exceeds the 
limit, the line will be disconnected.
When one of the following features is used, the TRS level of the extension can be 
temporarily changed. If two or more of these features are used simultaneously (Dial Tone 
Transfer is used while the extension is locked, for example), the TRS level of the feature 
with the highest priority is applied for the duration of the call. The numbers below (1 
through 4) indicate the priority of each feature, with 1 having the highest priority, and 4 
having the lowest.

1.8.2 Extension Lock
Description
Extension users can lock their telephones to prevent unauthorized use—useful for situations 
when extension users must leave their desks temporarily.
When Extension Lock is engaged, the extension’s Toll Restriction (TRS) level (  1.8.1 Toll 
Restriction (TRS)) is temporarily changed to another level, thereby determining which CO line 
calls can be made from the locked extension by another user.
An extension personal identification number (PIN) is required to unlock a locked extension (  
1.22.1 Extension Personal Identification Number (PIN)), however, anyone can engage 
Extension Lock, as no PIN is required.
This feature is also known as Electronic Station Lockout.
Conditions
This feature also restricts changing the Call Forwarding (FWD) destination. (  1.3.1.2 
Call Forwarding (FWD))
Remote Extension Lock
Allows an extension assigned as a manager to lock or unlock an extension. When a 
manager locks an extension remotely, the extension’s user cannot unlock it. When a user 
locks an extension, a manager can override the lock and unlock the extension.
This feature is also known as Remote Station Lock Control.
TRS Level
The TRS level of a locked extension is assigned through system programming. (  TRS 
Level for Extension Lock [510]).
Other features can also temporarily change an extension’s TRS level, similar to Extension 
Lock. If an extension is locked, the TRS level determined by the following features takes 
priority. The numbers below (1 through 3) indicate the priority of each feature, with 1 
having the highest priority, and 3 having the lowest.
1)Dial Tone Transfer (  1.8.3 Dial Tone Transfer)

1.8.3 Dial Tone Transfer
Description
Allows an extension assigned as a manager change the Toll Restriction (TRS) level (  1.8.1 
Toll Restriction (TRS)) of an extension for the purpose of making a single CO line call. The 
extension user first calls a manager, who then presses the Toll Restriction button, giving the 
extension user a dial tone from which the normally unauthorized call can be made.
[Example]
A hotel guest calls the front desk and asks for the telephone’s toll restriction to be lifted in order 
to make an international call.
Toll Restriction Button
A manager extension must store the TRS level granted by the Dial Tone Transfer beforehand, 
when assigning a flexible button as the Toll Restriction button.
Conditions
Dial Tone Transfer is effective for only one CO line call.

1.8.4 Walking COS
Description
Extension users can temporarily assign their own Class of Service (COS) to another extension, 
allowing them to make calls as if from their own telephones.
This feature is useful when a manager needs to borrow another employee’s telephone to make 
a call. The superior enters the Walking COS feature number followed by his or her extension 
number and extension personal identification number (PIN), then makes the call.

Other features can be accessed by Walking COS, such as DND Override (  1.3.1.3 Do Not 
Disturb (DND)) and Executive Busy Override (  1.7.2 Executive Busy Override). The same 
privileges and restrictions normally applied to a user are applied when using Walking COS.
Conditions
Walking COS is effective for only one CO line call or one operation at a time.
When making a call with Walking COS:
a)The extension number of the Walking COS user, not the borrowed extension, is 
logged by Station Message Detail Recording (SMDR). (  1.21.1 Station Message 
Detail Recording (SMDR))
b)The Walking COS user’s Itemized Billing Code for ARS will be used.

1.8.5 Verified Code Entry
Description
A verified code is a code which is assigned its own Class of Service (COS), and therefore 
contains a Toll Restriction (TRS) level (  1.8.1 Toll Restriction (TRS)). Using a verified code, 
a PBX user can use any extension to make CO line calls with his or her own set of privileges 
and restrictions. You may think of Verified Code Entry as Walking COS for PBX users who do 
not have their own extensions.
Because a verified code user normally has no extension telephone, the verified code will be 
logged by Station Message Detail Recording (SMDR) for identification or accounting purposes 
when making a CO line call.
Other features can be accessed by Verified Code Entry, such as DND Override, Executive 
Busy Override, etc.
Each verified code can be assigned a user name, COS, verified code, personal identification 
number (PIN), and Itemized Billing Code for ARS. A verified code PIN is required to use 
Verified Code Entry.

[Programming Example: Verified Codes]
Conditions
WARNINGWhen a third party discovers the personal identification number (PIN) (verified code PIN/
extension PIN) of the PBX, there will be a risk that they will make fraudulent phone calls 
using the telephone line, and the cost will be charged to your own account. In order to 
avoid this problem, we strongly recommend the following points:
a)Carefully maintain the secrecy of the PIN.
b)Specify a complicated PIN as long and random as you can make it.
c)Change the PIN frequently.
Verified Code Entry is effective for only one CO line call or one operation at a time.
When making a call with Verified Code Entry:
a)The verified code, not the borrowed extension number, is logged by SMDR. (  1.21.1 
Station Message Detail Recording (SMDR)) It will appear as   + [the verified code].
b)The verified code user’s Itemized Billing Code for ARS will be used.
Verified Code PIN
A verified code PIN can also be assigned for each verified code through manager 
programming as well as through system programming.
Verified Code Entry through DISA
This feature is also available through Direct Inward System Access (DISA). (  1.15.6 
Direct Inward System Access (DISA))
Verified Code PIN Lock
If the PIN is entered incorrectly three times, the line will be disconnected. If an incorrect 
PIN is entered a preprogrammed number of times, the PIN will be locked. Only an 
extension assigned as a manager can unlock a PIN, after which it will be reset.

1.9 Automatic Route Selection (ARS) Features
1.9.1 Automatic Route Selection (ARS)
Description
Different telephone carriers charge different rates for calls placed to different areas. Your PBX 
may use different telephone carriers to make calls to different areas in an effort to reduce costs.
Automatic Route Selection (ARS) is a feature which automatically selects different carriers 
each time a CO line call is made. In order to use ARS effectively, various ARS-related tables 
must be preprogrammed to tell the PBX which calls should be placed using which carriers, 
during which time of day.
If you do not activate ARS, if ARS is bypassed, or if you do not use multiple carriers, CO line 
calls will be connected via the carrier contracted for each line (default carrier).

78 Feature Guide
[Carrier Selection Procedure Flowchart]
The numbers in parentheses indicate the corresponding items found under [Programming 
Procedures] on the following pages.
[Programming Procedures]
1.
ARS Mode (  ARS Mode [320])
ARS is turned on by selecting under which circumstances it operates – either when an 
extension user makes a call using the Idle Line Access method, or when any CO Line 
Access method is used. (  1.5.5.3 CO Line Access). ARS can also be turned off for the 
entire system.
2.Leading Number Exception Table
Once ARS is activated, store the telephone numbers that will bypass ARS in the Leading 
Number Exception Table. 
Note that the first few digits (leading number) of a telephone number, such as an area code 
or local exchange, can also be stored, so that all calls to those areas or exchanges are 
exempted from ARS. Also note that the CO Line Access number is always ignored by ARS

and does not need to be programmed here.
Calls that are exempt from ARS are connected to the user-selected line, via the default 
carrier for that line.
[Programming Example: ARS Leading Number Exception Table]
In this example:
555, 556, and 567 are local exchanges. (555-XXXX, 556-XXXX, 567-XXXX)
These calls can be made using any carrier, and are therefore exempt from ARS.
3.Leading Number Table
Next, store the leading numbers of telephone numbers that should be routed by ARS, and 
assign a Routing Plan to each leading number that will control how calls containing these 
leading numbers are routed. 
When an extension user dials a number which contains a leading number stored in the 
ARS Leading Number Table, the call will be routed the corresponding Routing Plan 
assigned here. Note that the CO Line Access number is always ignored by ARS and does 
not need to be programmed here.
Before programming the details of each Routing Plan (explained below), you can simply 
assign here the same Routing Plan number to all the different leading numbers which will 
be routed the same way.
If a dialed number matches two or more leading numbers stored in the ARS Leading 
Number Table, the lowest numbered location will have priority.
[Programming Example: ARS Leading Number Table]
Additional Number of Digits
In order for calls to be made using the desired carrier, telephone numbers dialed by 
extension users must be modified to meet the criteria required by the carrier. (Refer to 5. 
Carrier Table.) This modification usually involves removing digits and adding access codes 
to the beginning of the dialed number.
In situations where a preprogrammed number (such as an Itemized Billing Code) must be 
added automatically after the telephone number that was dialed by the extension user, set 
the Additional Number of Digits to a value greater than 0.

4.Routing Plan
Since the preferred carrier may vary depending on the time of day, you can create an ARS-
specific time table and break each day of the week into different time blocks. A different 
carrier can then be assigned to each time block.
Routing Plan Time Table: For each Routing Plan, a different carrier can be assigned for 
each time of day and each day of the week. Each day can have up to four programmable 
time blocks.
Routing Plan Priority: For each Routing Plan, a different carrier can be assigned a 
different priority for each time of day. Generally, the carrier assigned to priority 1 will be 
used, however, if the CO lines assigned to this carrier are busy, a different available carrier 
will be used according to priority level.
5.Carrier Table
Each carrier must be programmed in the Carrier Table. Here each carrier is assigned a 
carrier number, name, the CO lines it is used with, etc.
Carrier Name: Assign a name for the carrier. Used only as a reference.
CO Line Group: Assign the CO line groups which can be used when making calls via this 
carrier.
Carrier Access Code:  Enter the carrier’s access code. Consult carrier for details.
Removed Number of Digits: There may be circumstances where the user-dialed number 
must be modified in order for the carrier to connect the call. In this case, enter here the 
number of digits to be removed automatically from the beginning of the dialed number.
Modify Command: When a call is made using this carrier, the telephone number must be 
modified to meet the criteria required by the carrier in order to connect the call. Program 
here the commands needed to modify the user-dialed number as necessary.
