Alarm lets any station extension work like an Alarm clock. An extension user can have Alarm remind them of a meeting or an appointment. There are two types of Alarms:
Alarm 1 (sounds only once at the preset time)
Alarm 2 (sounds every day at the preset time)
Multibutton display telephones have a 3-line, 24 character per line Alphanumeric Display that provides
various feature status messages. These messages help the display telephone user process calls, identify
callers and customize features
3、Analog Communications Interface (ACI)
The Analog Communications Interface (ACI) feature uses a PGD(2)-U( ) ADP (Door Phone/Paging)
adapter to provide two analog ports (with associated relays) for Music on Hold, External Paging, Door
Boxes and auxiliary devices such as tape recorders and loud bells. The system allows up to 48
PGD(2)-U( ) ADPs (when used for ACI ports) for a maximum of 96 analog ports. Each PGD(2)-U( ) ADP
requires an unused port on a CD-8DLCA/CD-16DLCA blade.
Answer Hold allows a multiline terminal user to press the flashing Answer Key to answer an incoming
ringing call or a Camp-On call. When the multiline terminal user is already answering a call, the first call is
automatically placed on hold
Multiline terminals have an Answer Key with an LED that flashes when the Multiline Terminal user
receives an incoming CO/PBX, Tie/DID transfer, or CO/PBX transfer call. When multiple calls are
received, The Answer Key is used to pick up calls and continues flashing until the last unanswered call is
answered. Press the Answer Key during a call to hold the current call and allow the next call to be
6、Attendant Call Queuing
Attendant extensions can have up to 32 incoming calls queued before additional callers hear busy tone.
This helps minimize call congestion in systems that use the attendant as the overflow destination for
unanswered calls. For example, you can program Direct Inward Lines and Voice Mail calls to route to the
attendant when their primary destination is busy. With Attendant Call Queuing, unanswered calls would
normally “stack up” for the attendant until they can be processed.
The 32 call queue total includes Intercom, DISA, DID, DIL, Tie Line and transferred calls. If the attendant
does not have an appearance for the queued call, it waits in line to be answered. If the attendant has
more than 32 calls queued, an extension can Transfer a call to the attendant only if they have Busy
7、Automatic Call Distribution (ACD)
Automatic Call Distribution (ACD) uniformly distributes calls among agents of a programmed ACD Group.
When a call rings into an ACD Group, the system automatically routes the call to the agent that has been
idle the longest. Automatic Call Distribution is much more sophisticated and comprehensive than
Department Calling and other group services – it can accurately judge the work load at each agent and
distribute calls accordingly. The system allows up to 64 ACD Groups and 256 ACD agents.
You can put any agent in any group. An agent can be in more than one group only when using AICs. This
allows, for example, a Technical Service representation to answer customer service calls at lunch when
many of the Customer Service representatives are unavailable.
The ACD Master Number is the extension number of the whole group. Calls directly ringing or transferred
to the ACD Master number enter the group and are routed accordingly. Although the master number can
be any valid extension number, you should choose a number that is out of the normal extension range.
Automatic Release drops the line circuit when an outside party abandons the call. For this feature to work
with Loop Start Trunks, the CO/PBX providing the outside line must provide a timed disconnect signal.
Automatic Release is normally provided on Ground Start, DID, ISDN, and Tie Line trunks.
9、Automatic Route Selection
Automatic Route Selection (ARS) provides call routing and call restriction based on the digits a user dials.
ARS gives the system the most cost-effective use of the connected long distance carriers.
Background Music (BGM) sends music from a customer-provided music source to the
speakers of the Multiline Telephone when the station is idle.
Barge-In permits an extension user to break into another extension user’s established call, including
Conference calls. This sets up a Conference-type conversation between the intruding extension and the
parties on the initial call. With Barge-In, an extension user can get a message through to a busy co-worker
12、Battery Backup – System Power
A built-in battery provides complete system operating power for approximately 30 minutes during
commercial power outages. When optional (locally provided) batteries are connected and fully charged,
full system operation can be maintained for an extended time. Actual time depends on system
configuration, traffic conditions, and the capacity of the batteries
13、Call Duration Timer
Call Duration Timer lets a multiline terminal with an LCD time their trunk calls on the telephone display.
This helps users that must keep track of their time on the telephone. For incoming trunk calls, the Call
Time begins as soon as the user answers the call.
14、Call Forwarding – Centrex
The Call Forwarding – Centrex feature allows a station to forward an incoming PBX/Centrex CO call to an
outside location using the same PBX/Centrex CO line to free the line for additional use.
Call Forwarding – Centrex supports the following:
��� Call Forward – Immediate
��� Call Forward – Busy
��� Call Forward – No Answer
��� Call Forward – Busy/No Answer
Call Forwarding permits an extension user to redirect their calls to another extension or an off-premise
number. Call Forwarding ensures that the user’s calls are covered when they are away from their work
16、Call Forwarding with Follow Me
While at a co-worker’s desk, a user can have Call Forwarding with Follow Me redirect their calls to the coworker’s
extension. This helps an employee who gets detained at a co-worker’s desk longer than
expected. To prevent losing important calls, the employee can activate Call Forwarding with Follow Me
from the co-worker’s telephone.
Call Forwarding with Follow Me reroutes calls from the destination extension. To reroute calls from the
initiating (forwarding) extension, use Call Forwarding.
17、Call Forwarding, Off-Premise
Off-Premise Call Forwarding allows an extension user to fo, rward their calls to an off-site location. By
enabling Call Forward, Off-Premise, the user can, stay in touch by having the system forward their calls
while they are away from the office. The forwarding destination can be any telephone number the user
enters, such as a mobile phone, home office, hotel or meeting room. Off-Premise Call Forwarding can
route the off-site telephone number over a specific trunk or through a trunk group, Automatic Route
Selection or Trunk Group Routing
18、Call Forwarding/Do Not Disturb Override
An extension user can override Call Forwarding or Do Not Disturb at another extension. This is helpful,
for example, to dispatchers and office managers that always need to get through
Call Monitoring allows selected Multiline Terminal Users to monitor another user’s conversation without
the ability to participate. A programmable audible alert tone can be sent to that station user. Without the
audible alert (silent monitor), no indication is provided to either the monitored station or the outside party
Call Redirect allows a multiline terminal user to transfer a call to a predefined destination (such as an
operator, voice mail, or another extension) without answering the call. This can be useful if you are on a
call and another rings in to your extension. Press the Call Redirect key to transfer the call, allowing you to
continue with your current call
With Call Waiting, an extension user may call a busy extension and wait in line (Camp-On) without
hanging up. When the user Camps-On, the system signals the busy extension with two beeps indicating
the waiting call. The call goes through when the busy extension becomes free. Call Waiting helps busy
extension users know when they have additional waiting calls. It also lets callers wait in queue for a busy
extension without being forgotten
When an extension user calls a co-worker that does not answer or is busy, they can leave a Callback
request for a return call. The user does not have to repeatedly call the unanswered extension back,
hoping to find it idle.
23、Caller ID Call Return
The Caller ID Call Return feature allows the voice mail system to use Caller ID information captured with
the message to call and connect the person that left the message with the voice mail user that is checking messages
Caller ID allows a display terminal to show an incoming caller’s telephone number (called the Directory
Number or DN) and optional name. The Caller ID information is available as pre-answer display. With the
pre-answer display, the user previews the caller’s number before picking up the ringing line.
25、Class of Service
Class of Service (COS) sets various features and dialing options (called items) for extensions. The
system allows any number of extensions to share the same Class of Service. An extension can have a
different Class of Service for each of the Night Service modes. This lets you program a different set of
dialing options for daytime operation, nighttime operation and even during lunch breaks. An extension
Class of Service can be changed in system programming or via a Service Code (normally 677). There
are 15 available Classes of Service.
Conference lets an extension user add additional inside and outside callers to their conversation. With
Conference, a user can set up a multiple-party telephone meeting without leaving the office. The
CD-CP00-AU provides 64 conference ports, to allow any number of internal or external parties to be
conferenced together for a limit of 32 parties. This means that one extension can conference up to 31
internal and/or external parties together (the originator would be the 32nd party reaching the maximum of
32). While this Conference call is active, another user can initiate a separate Conference also for a limit of
32 parties, or any number of conferences can be initiated with any number of parties (up to 32) until all 64
Conference ports are busy.
