The Comdial DX-120 or DX120 is an extremely capable telephone system with the Comdial Vertical Edge 120 or the legacy 7260 Edge telephones it is very expandable and feature rich. The Comdial DX-120 DX120 was introduced in 2007 and end of life in 2014. In those 7 years many system shave been installed which is great to find replacement used parts. One issue we’ve found is the main cabinet mother board develops an incurable “cancer”. It begins one day and by 3 months the system has fully failed. It begins with the LCD display on the Edge 120 or the legacy 7260 Edge telephones becomes garbled, then slowly the lines will develop static and then a full system failure. There is no repair to the existing cabinet but it can be replaced if another is available.

Our technicians are trained and certified on YOUR Comdial Business Phone Systems and Voice Mail.
We have many “crash systems” and repair parts in stock to get your system up and operating the same day.
Our suppliers can provide us with almost any equipment including unusual and outdated brands. We can usually have your system operational by the next morning.

Monitor – Extension/Outside Line
The DX-120 system allows users to monitor conversations at other
extensions for the purposes of service observance. Monitoring of busy
extensions and outside lines is possible only at extensions with a
Monitor Class of Service that has priority over the Monitor Class of
Service of the extension to be monitored.
Since this feature is very similar to Intrusion, it is possible to “shift”
between these two features when Monitor has been invoked.

LEGAL NOTICE:
This feature may violate privacy laws if used in a manner that is
inconsistent with requirements of these laws. Manufacturer assumes no
responsibility with regard to the use of this feature. It is provided for the

Multiple Call Handling
(USING CALL KEYS FOR MANAGING MULTIPLE CALLS)
The Multiple Call Handling utility known as Call Key (Feature Code 66)
provides a method for tracking the status for a “pool” of CO lines. More
specifically, the Call Key reflects the status of any active Trunk calls
for a specific extension (assuming there is not a Line Key programmed
for that individual CO line that the Trunk call is associated with).
Furthermore, you can program multiple Call Keys on your phone to
allow for tracking the status and management of additional,
simultaneous Trunk calls.
A Feature key (i.e., Call Key) can be programmed on any designated
Vertical Comdial phone for use in handling multiple calls*. The Call
Key can be programmed on any feature key of an extension. Once
invoked, the Call Key becomes associated with that Trunk call and the
Call Key lamp indicator reflects the status of that Trunk call for the
duration of that call at the extension.

*Check with your System Administrator to find out if your phone Comdial Vertical Edge 120
is programmed for handling multiple calls as described above.
NOTE
• The maximum number of Call Keys that can be programmed is equal to
the number of feature keys available on the phone being used.
• Only programmed Call Keys work. The Feature Access Code itself is
not valid.
• The Call Key will work for any CO line (i.e., loop start as well as digital –
T1 or T1/PRI). However, if you have a Line Key programmed for a
particular line then the Line Key will be used for that particular line.
In other words, Call Keys are only associated with CO lines that do not
have a Line Key programmed for them.
• The Call Key will provide status for Trunk calls whether the Trunk call is
incoming or outgoing. However, you cannot press an available Call Key
to access a CO line.

Page 32 Edge 120 Digital Executive Telephone User Guide
 Additional information about Multiple Call Handling
This section of this guide provides the following information with
regard to Multiple Call Handling:
• Incoming Calls
• Outgoing Calls
• Putting Calls on Hold
• Transferring Calls
• Conference Calls
• Lamp Indicators
Incoming Calls
Multiple Call Keys can be programmed at a user’s extension. The
table below provides detail of how the Call Key will function as for
multiple incoming Trunk calls.
CALL KEY SETTING RESULT
No Call Key programmed Intercom calls and Trunk calls are processed as usual.
Only one Call Key The Call Key will become associated with and provide status
programmed for the incoming Trunk call assuming both of the following
conditions are met:
• There is not a Line Key already programmed for the line
that the incoming trunk call is coming in on.
• There is an available Call Key programmed on the phone
(i.e., the Call Key that is programmed is not already being
used by another trunk call on that extension)
Note
Regardless of whether the extension is busy (on a call) or
not, once the call becomes associated with the available Call
Key, the lamp indicator will be a fast flashing red light.
If you are already on a call, answering the new incoming call
by pressing the Call Key will automatically put the initial call Comdial Vertical Edge 120
on hold.
Multi Call Key Programming Multiple Call Keys allows you to simultaneously
Programmed manage multiple Trunk calls. The additional programmed
Call Keys follow the same rules that apply when only a single
Call Key is programmed (refer above).
However, each Call Key provides status for the Trunk Call it
became associated with.
NOTE
When there is an incoming Trunk call, the Call Key will NOT be invoked /
utilized if there is a Line Key programmed for the incoming Trunk call on the
phone.

Edge 120 Digital Executive Telephone User Guide Page 33
 Outgoing Calls
When an idle Call Key is pressed, “NO INCOMING CALL” message
will be shown on the phone display (i.e., Call Keys cannot be pressed
to access available CO lines). However, once a Trunk is seized by an
extension through any means such as: Trunk Directory Number, Trunk
Route Directory Number, or Speed Dial, the first available Call Key will
become associated with that Trunk call, assuming there is no Line Key
programmed for the seized Trunk at the extension.
The Call Key lamp indicator provides status of that Trunk call until that
trunk call is completed at that extension.

Placing Call Key Calls on Hold
A Call Key call can be placed on System HOLD or Exclusive HOLD.
The table below describes the status indicators for both cases (the
descriptions below do not apply to the Hold Key itself (see page 36):
HOLD SETTING DESCRIPTION
System HOLD • A slow flashing green light will be provided on the Call Key
(Press the HOLD key) of the holding extension.
• A slow flashing red light indicator will be provided on the
associated Line Key of other extensions in the system.
Other extensions can pick up this Trunk call
Exclusive HOLD • A fast flashing green light indicator will be provided on the
(Press the Feature key Call Key of the holding extension.
+ HOLD) • A solid red light indicator remains on the associated Line
Key of other extensions in the system. Only the extension
which placed this call on “exclusive hold” can retrieve this
Trunk call.
NOTE
• When a user is on a call at Call Key 1, he/she can answer a second call
which is received at Call Key 2. The first call will be put on exclusive
hold automatically no matter whether or not “AUTO HOLD” is enabled.
• When a trunk call(s) is placed on hold and there is no Line Key or Call
Key at the extension, the phone will ring to remind you to retrieve the
held call(s).

Page 34 Edge 120 Digital Executive Telephone User Guide
 Transferring Calls
With the Call Key, users are able to track status of Trunk calls without
needing a Line Key for each CO line. As indicated, the Call Key
becomes associated with the Trunk call and provides status for that
call as long as the call is active at the user’s extension. When
transferring Call Key calls, the Call Key provides status during the
transfer process.
The table below indicates the Call Key lamp status when a Trunk call
is being transferred from one extension to another extension.
NOTE
The table below assumes that neither Extension A nor Extension B has a
Line Key programmed for the CO line that the Trunk call is using, thus the Comdial Vertical Edge 120
status is provided on the Call Keys.

Conference Calls
When you establish a conference call with trunks, assuming there is
no Line Key for the CO lines that are utilized in the conference call and
you have available Call Keys, the Call Key lamp indicator will provide
status of the active Trunk calls that make up the conference call. You
can deliberately release or talk privately by pressing the associated
Call Key.
Once you (controller) perform an Unsupervised Conference (Feature
+77), the Call Key lamp indicators involved with the conference call
become dark and available and the user’s extension is returned to idle.
If you rejoin the conference call (Feature +77), the Call Keys will
provide status of the trunks involved in the conference call assuming
there are available Call Keys available.

 Multiple Call Handling Lamp Indicators
There are 2 types of Lamp Indicators:
• Hold Key Lamp Indicators
• General Call Key Lamp Indicators

Hold Key Lamp Indicators
The purpose of the Hold Key Lamp is to allow you to handle multiple
calls in the DX-120 more easily. This light appears next to the HOLD
button.
NOTE
The Hold Key Lamp does not function when a 7261-00 Edge 120 phone
is connected to a DX-80.
Trunk Call Holding
The Hold Key lamp is fast red flashing when Trunk calls are placed
on either System Hold or Exclusive Hold by the extension.
Intercom Call Holding
The Hold Key lamp is slow red flashing when Intercom calls are
placed on Hold by the extension.
NOTE
• The Hold Key Lamp is useful handling multiple calls on hold, especially
for systems with T1 or T1/PRI where there are no Line Key(s) or Call
Key(s) programmed at the extension. In this case the Hold Key Lamp
provides a reminder for you that there is a call(s) on Hold.
• Held Trunk calls have a higher indicator priority when both Trunk and
Intercom calls are placed on Hold at the same time.
When Trunk and Intercom calls are on hold at the same time, Intercom
calls can not be retrieved by pressing the Hold Key until all of the Held
Trunk calls are first retrieved and released (completed, transferred,
etc.).
The lamp indication of the Hold Key lamp immediately changes from a
fast flash slow flash once there are no more Held Trunk calls at the
extension.
