1.9.6 Flash/Recall
Description
A proprietary telephone (PT) user can use the FLASH/RECALL button to disconnect the current call and 
start another call without hanging up. For example, if this button is used to disconnect an outside (CO) line, 
the extension user will hear a new dial tone from the same outside (CO) line.
Conditions
FLASH/RECALL Button Mode 
One of the following modes can be selected through system programming ( Flash/Recall Key Mode 
[110]):
a)MODE 1: EFA mode ( 1.9.7 External Feature Access (EFA)) 
An EFA signal is sent for the specified duration ( Flash/Recall Time [418]). 
b)MODE 2: Flash/Recall mode 
A flash/recall signal is sent for the FLASH/RECALL button is pressed if the length of time that the 
button is pressed is longer than the specified duration (
 Flash/Recall Time [418]). If the length 
of time that the button is pressed is shorter than the specified duration, an EFA signal will be sent 
for the specified duration.
 This feature functions only if the FLASH/RECALL button is set to MODE 2: Flash/Recall mode. 
Disconnect Time 
The amount of time between successive accesses to the same outside (CO) line is programmable for 
each outside (CO) line (
 Disconnect Time [422]).
 This feature generates an SMDR call record ( 1.19.1 Station Message Detail Recording (SMDR)) 
and restarts the call timer. The notation F/ will be logged along with the new dial number.

1.9.8 Outside-to-Outside (CO-to-CO) Line Call Duration
Description
When a call between 2 outside parties is established, the call duration is restricted by a timer ( CO-to-CO 
Line Call Duration [205]). Both parties will hear a warning tone 15 seconds before the timer expires. When 
the timer expires, the call is disconnected.
Conditions
Lockout 
If one party in a conversation goes on-hook, the call between both parties will be disconnected. A 
reorder tone is sent to the off-hook par ty before the call is disconnected. No operation is necessary.
 The Outside-to-Outside (CO-to-CO) Line Call Duration feature applies to the following calls:
– Calls forwarded by the FWD to Outside (CO) Line feature ( 1.3.1.2 Call Forwarding (FWD))
– Calls transferred by the Call Transfer to Outside (CO) Line feature ( 1.10.1 Call Transfer)

1.9.9 Paralleled Telephone
Description
Any proprietary telephone (PT) can be connected in parallel with a single line device, such as a single line 
telephone (SLT), fax machine, or modem.
 
When parallel mode is used, the 2 telephones function as follows:
 Both share one extension number.
 Either telephone or device can make or answer calls.
Conditions
 System programming determines the SLTs that can be connected in parallel with a PT ( Paralleled 
Telephone [610]).
 When the SLT is in operation, the display and LED (Light Emitting Diode) indicator on the paired PT will 
function in the same way as when the PT is in operation. 
 The following features cannot be used with an SLT connected in parallel with a PT:
– Call Splitting
– Call Waiting Caller ID
– Conference
– Door Open while connected to the doorphone
– External Feature Access (EFA)
– Hot Line
 An SLT connected in parallel with a PT will not ring if the PT is:
– In Hands-free Answerback mode ( 1.4.1.4 Hands-free Answerback).
– In Voice-calling mode (Alternate Receiving—Ring/Voice) ( 1.5.1.1 Intercom Call).
 An extension user cannot make a call from the SLT if the PT is:
– Playing background music (BGM)
– Receiving a paging announcement over the built-in speaker
– In programming mode
 Both the PT and the SLT will ring for incoming calls (if the ringer is turned on).

1.9.10 Calling Party Control (CPC) Signal Detection
Description
A CPC (Calling Party Control) signal is an on-hook indication (disconnect signal) sent from an outside (CO) 
line when the other party hangs up. To maintain efficient utilization of outside (CO) lines, the PBX monitors 
each lines status and when a CPC signal is detected on a line, the PBX disconnects the line and alerts the 
extension with a reorder tone.
Conditions
 CPC Signal Detection is programmable for incoming outside (CO) line calls ( CPC Signal 
Detection—Incoming [420]) and for outgoing outside (CO) line calls ( CPC Signal Detection—
Outgoing [421]).
 If a CPC signal is detected during a call between a caller using the DISA feature ( 1.14.6 Direct 
Inward System Access (DISA)) and an extension or an outside party, the call will be disconnected.

1.10 Transferring Features
1.10.1 Call Transfer
Description
An extension user can transfer a call to another extension or to an outside party.  
The following features are available:
Call Transfer with Announcement is also known as Call Transfer—Screened.
Call Transfer without Announcement is also known as Call Transfer—Unscreened.
Conditions
 System programming determines the extensions that are able to transfer calls to an outside party ( 
Call Transfer to CO Line [606]). Single line telephone (SLT) users cannot transfer calls to an outside 
party.
Transfer Recall for Call Transfer without Announcement 
If the transfer destination extension does not answer within a preprogrammed time period ( Tr a n s f e r  
Recall Time [201]), the call will return to the extension that transferred the call. If there is no answer for 
30 minutes after Transfer Recall starts, the call will be disconnected.
One-touch Transfer 
Direct Station Selection (DSS) Console users and proprietary telephone (PT) users can hold an outside 
(CO) line call and quickly transfer it to an extension by pressing the DSS button directly (
 One-touch 
Transfer Using a DSS Button [005]). 
A flexible CO/DSS/MESSAGE button can also be customized as a DSS button.
 Music, if available, is sent to the held outside party while the call is being transferred ( 1.11.4 Music 
on Hold). An external audio source or tone can be selected as the Music on Hold through system 
programming ( Music on Hold [111]). 
Outside (CO) Line Call Duration 
If an outside (CO) line call is transferred to an outside party, the call duration will be restricted by a 
system timer (
 CO-to-CO Line Call Duration [205]). Both parties will hear a warning tone 15 seconds 
before the timer expires ( 1.9.8 Outside-to-Outside (CO-to-CO) Line Call Duration). The extension 
that transferred the call will also hear a ring tone or an alarm tone 50 seconds before the timer expires 
(
 1.11.1 Call Hold). When the timer expires, the call is disconnected unless the extension joins the 
conversation again.
 If a CPC (Calling Party Control) signal is received from an outside (CO) line, the corresponding call 
between 2 outside parties will be disconnected.
Consultation Hold 
When a transferring party presses the TRANSFER button on a PT or the Recall/hookswitch on an SLT, 
the transferred party is automatically placed on consultation hold (
 1.11.5 Consultation Hold).
FeatureTransferring method
With AnnouncementTransfer is completed after announcing the transfer to the destination 
party.
Without AnnouncementTransfer is completed without an announcement.  
After dialing the destination extension number and hearing a ringback 
tone or busy tone, the originator can replace the handset.

1.11 Holding Features
1.11.1 Call Hold
Description
An extension user can put a call on hold. The following Call Hold features are available:
Pressing the HOLD button multiple times alternates between General and Exclusive Call Hold.
Conditions
 Using the Call Hold feature, a PT user can have one intercom call and multiple outside (CO) line calls 
on hold at the same time. To hold multiple intercom calls, the user should use the Call Park feature (
 
1.11.2 Call Park). Using the Call Hold feature, a single line telephone (SLT) user can have either one 
intercom call or one outside (CO) line call on hold. To hold multiple calls, the user should use the Call 
Park feature.
 If an outside party is placed on hold and the call is not retrieved within 30 minutes, the call is 
automatically disconnected.
Music on Hold 
Music, if available, is sent to the outside party on hold ( 1.11.4 Music on Hold). An external audio 
source or tone can be selected as the Music on Hold through system programming ( Music on Hold 
[111]). 
 Doorphone calls cannot be put on hold.
Hold Recall 
If a call on hold is not retrieved within a preprogrammed time period ( Hold Recall Time [200]), a ring 
tone will be heard at the extension that put the call on hold. If the extension is engaged in a call when 
the timer expires, an alarm tone will be heard. If the hold recall time is set to Disable, no tone will be 
heard. Going off-hook after the hold recall time has expired automatically re-establishes the 
conversation with the call on hold.
SLT Hold Mode 
It is possible to specify how calls are held and transferred with an SLT when the Recall/hookswitch is 
pressed for less than 1000 ms. 
 
The following methods ( SLT Hold Mode [104]) are available:
FeatureDescription
General Call HoldAny extension can retrieve a held call.
Exclusive Call HoldOnly the proprietary telephone (PT) user who held the call can retrieve it.

Feature Guide 79
If the following occurs frequently with an SLT, select Hold-2 or Hold-3:
1)When an SLT user goes on-hook to end a call, the call is mistakenly placed on hold.
2)When the SLT user subsequently answers the Hold Recall tone, a busy tone or reorder tone 
from the telephone company is heard.
The above case occurs if a call is not disconnected after going on-hook. To avoid these problems, select 
Hold-2 or Hold-3. Every call will be disconnected unless the Call Hold feature number is entered 
after pressing the Recall/hookswitch in Hold-2 and Hold-3.

1.11.2 Call Park
Description
An extension user can hold a call by placing it into a common parking zone of the PBX. A parked call can 
be retrieved by any extension user. This feature is useful when an extension user wants to hold more than 
one intercom call with a proprietary telephone (PT), or more than one intercom call or outside (CO) line call 
with a single line telephone (SLT).
Conditions
Call Park Recall 
If a parked call is not retrieved within a preprogrammed time period ( Hold Recall Time [200]), a ring 
tone will be heard at the extension that parked the call. If the destination is engaged in a call when the 
timer expires, an alarm tone will be heard.
 If a parked call is not retrieved within 30 minutes, it is automatically disconnected.
Retry 
If the specified parking zone is occupied, the extension user will hear a busy tone. While hearing a busy 
tone, the user can retry by selecting another parking zone.
