Feature Guide 61
Host PBX Access Code (Access Code to the Telephone Company from a Host PBX)) or Carrier 
Exception code.
 The inter-digit timer ( Inter-digit Time [208]) applies until the TRS check is completed. When the timer 
expires, the outgoing outside (CO) line call is disconnected while dialing, if enabled through system 
programming (
 No Dial Disconnection [211]). For a single line telephone (SLT), an outgoing outside 
(CO) line call will be released from the DTMF (Dual Tone Multi-Frequency) receiver when the inter-digit 
timer expires.
 The COS of extensions locked by the Extension Lock or Remote Extension Lock feature ( 1.8.3 
Extension Lock) can be assigned ( TRS—Extension Lock Class [312]) so that even a locked 
extension can make outside (CO) line calls. The higher COS number will take precedence. If, for 
example, COS 3 is assigned to an extension (
 TRS-COS—Day/Night/Lunch [601-603]) and the COS 
of locked extensions is assigned as 4, when the extension is locked, the PBX allows the extension 
user to make outside (CO) line calls using COS 4.
 The PBX can also be programmed to perform a TRS check for numbers that contain nondigits ( or #) 
( TRS Check for * and # [125]). If TRS check is disabled, the PBX ignores any nondigits that are 
dialed when checking, which is useful in preventing some unauthorized calls.

							1.8 Toll Restriction (TRS) Features
Feature Guide 63
Conditions
 This feature functions only for extensions whose:
– Account code mode is set to Verify-Toll ( Account Code Mode [605]).
– Class of service (COS) number is set to 3 through 5.
 If the extension user does not enter an account code or enters an invalid account code, an ordinary 
TRS check is performed.
 System programming determines whether SMDR ( 1.19.1 Station Message Detail Recording 
(SMDR)) logs the 4-digit account code or the 2-digit index of the account code when an extension user 
makes a call using this feature ( SMDR Account Code [805]).
 It is also possible to override TRS at another extension using the Walking COS feature ( 1.8.4 
Walking COS).

1.8.3 Extension Lock
Description
Extension users can lock their telephones to prevent unauthorized use. This is useful for situations when 
extension users must leave their desks temporarily. Any 4-digit code can be used to lock and unlock an 
extension.
 
This feature is also known as Electronic Station Lockout. 
Conditions
Remote Extension Lock 
An extension assigned as the operator or manager extension can remotely lock or unlock an extension 
using a Direct Station Selection (DSS) Console. This feature functions only if the operator or manager 
has set the extension password. When the operator or manager locks an extension remotely, the 
extensions user cannot unlock it. When a user locks an extension, the operator or manager extension 
can override the lock and unlock the extension.
 
This feature is also known as Remote Station Lock Control.
 The class of service (COS) of extensions locked by the Extension Lock or Remote Extension Lock 
feature can be assigned (
 TRS—Extension Lock Class [312]) so that even a locked extension can 
make outside (CO) line calls. The higher COS number will take precedence. If, for example, COS 3 is 
assigned to an extension (
 TRS-COS—Day/Night/Lunch [601-603]) and the COS of locked 
extensions is assigned as 4, when the extension is locked, the PBX allows the extension user to make 
outside (CO) line calls using COS 4.
Extension Lock—CANCEL ALL 
The operator or manager can cancel this feature for all extensions simultaneously.
 This feature also functions as Incoming Call Log Display Lock ( 1.15.2 Incoming Call Log).  
The Incoming Call Log for the common area can only be locked or unlocked by the operator and 
manager.

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 or supervisor needs to borrow another employees telephone to make 
a call. The superior enters the extension password followed by the Walking COS feature number and his or 
her extension number, and then makes the call. The same privileges and restrictions normally applied to a 
user are applied when using Walking COS.
Conditions
 When making a call with Walking COS, the extension number of the Walking COS users extension is 
also logged by SMDR (
 1.19.1 Station Message Detail Recording (SMDR)).

1.9.2 Room Monitor
Description
An extension user can monitor a room or a door through another proprietary telephone (PT) or a doorphone 
without the destination party knowing. 
Conditions
 To monitor using this feature, an extension must have a PT with an AUTO ANS/MUTE button or a single 
line telephone (SLT) with a MUTE button. To be monitored using this feature, an extension must have

 System programming determines the extensions that can be monitored using this feature ( Room 
Monitor [612]).
 A doorphone access tone will be sent to a monitored doorphone before monitoring starts ( 1.14.1

it is possible to eliminate the tone through system programming ( Doorphone Access Tone [707]).
 Access tones will not be sent to a monitored PT. Paging tones will also not be received by a monitored 
PT.
