							Door Box 
&
From a Door Box installed at an entrance door, a visitor can press
the call button (like a door bell) to ring your phone.
The Door Box (P/N 88545) is a
self-contained Intercom unit
typically used to monitor an
entrance door.  A visitor at the door
can press the Door Box call button
(like a door bell).  The Door Box
then sends chime tones to all
extensions programmed to receive
chimes.  To answer the chime, the
called extension user just lifts the
handset.  This lets the user talk to
the visitor at the Door Box.  The
Door Box is convenient to have at a delivery entrance, for example.  It is not
necessary to have a co-worker monitor the delivery entrance; they just answer the
Door Box chimes instead.
The system can have up to four Door Boxes (numbered 1-4), installed at extensions
310, 311, 322 and 323 in the Main CEU.  Each Door Box has a distinctive chime
pattern.
Relay Box
The Relay Box (P/N 88546) provides relay contacts for up to four Door Box
locations. A relay typically enables an electric strike on an entrance door next to a
Door Box. After answering the Door Box chimes, you can press a dial pad key to
enable the relay which releases the door. The visitor at the door can then enter
without you having to open the entrance door for them. 
You can only install a Relay Box at extension 309 in the Main CEU. This provides
relays for the Door Boxes at extensions 311, 322 and 323. The Relay Box has a
normally open (NO) and normally closed (NC) contact for each Door Box. The relay
for the Door Box at extension 310 is currently unavailable.
Notes:
·The Door Box is a weather-tight unit, with an operating temperature range of
20oC to 60oC (-4oF to 140oF). It is not, however, intended for an outdoor installa-
tion directly exposed to the elements (e.g. rain or sunlight).
·You can only use a Door Box with software AUX Module Y2.0/Base Y5.0 or
higher.
Initial Configuration 
·No Door Boxes installed
·Relay Box not installed.

Any combination of DP and DTMF Central Office lines can be
connected to the DIGITAL SYSTEM. 
With Pulse to Tone Conversion, use your pulse (rotary) lines to
access computer services that require tone dialing (such as
banking, MCI, Sprint, etc.).
You can program the system for either DP or DTMF lines from the Central Office.
Pulse to Tone Conversion
Pulse to Tone Conversion lets you dial digits on a Dial Pulse (rotary) line, then
convert to tone dialing.  After you dial the pulse digits, you simply stop dialing for
six seconds.  Any digits you dial after the six-second pause will be dialed out as
tones.  When you hang up the call, the dialing mode automatically reverts to pulse.
Initial Configuration 
All Lines are CO Loop Start DTMF
Pulse to Tone Conversion enabled
Using the Feature
To convert to tone dialing
when using a pulse line:
1.Place call on pulse line and wait six seconds.
2.Dial more digits.
-If you call a Speed Dial number that contains a
pulse line and a pause, the system automatically
dials tone digits after the pause.

							Equa l A cc ess Compa tibility
&
Use an alternative long distance service without dialing its
telephone number. 
If the DIGITAL SYSTEM is installed in an Equal Access area, you can dial a code to
access a long distance carrier other than your main one (i.e., the one you access when
you dial 1).  The code is in the form 10XXX, where XXX is the carrier’s
identification code.  The identification code is set up by the local telephone company.
In software AUX Module Y2.0/Base Y5.0 or later, the system does not restrict Equal
Access codes. However, it restricts the phone number according to Toll Restriction.
In software versions prior to AUX Module Y2.0/Base Y5.0, once you manually dial
an Equal Access code, you can dial any number (i.e., you have unrestricted dialing)
unless your phone has any of the following options enabled in its Class of Service: 
·Only Intercom Call at Night, which prevents Equal Access dialing during the
Night Answer mode. 
·Only Local Calls at Night, which prevents Equal Access dialing to long dis-
tances numbers during the Night Answer mode. 
·Only Local Calls (Day or Night), which prevents Equal Access dialing to long
distance numbers.
The system never restricts an Equal Access call that is stored in System Speed Dial bin.

							Exte nded R inging

Calls can ring longer than usual to assist people who can’t readily
get to their phones (like a warehouse worker, for example).
Extended Ringing forces an unanswered call to ring an extension 15 times before the
system can reroute it to another extension.  For example, a Transfer would ring an
extension 15 times before recalling the extension that transferred it.
If an extension has Extended Ringing, the following types of calls ring it 15 times
before being rerouted:
·A Hunting call
·A Transfer 
·A recalling call on Hold 
·A ring-no-answer forwarded call 
·A Direct Inward Line 
·A Direct Inward Dialing call

							Exte nsion Hunting
&
Call handling among people in a sales or service department
becomes very efficient.  If one person is busy handling a customer,
the DIGITAL SYSTEM sends a new call to another person in the
group.  No need for an attendant to look for an available person to
take a call. 
Extension Hunting sends a call through a group of extensions until it is answered.  In
other words, if a call tries a Hunt Group extension and it is busy, the call tries (hunts
for) the next available extension in the group, and so on.
The following types of calls hunt when they come into a Hunt Group extension: 
·Ringing Intercom calls 
·Transferred calls 
·Direct Inward Lines
·DISA calls
Voice-announced Intercom calls and lines assigned to a Hunt Group extension
through Program 16 do not hunt.
A Hunt Group can have any number of members, and the system can have any
number of Hunt Groups.  However, an extension can be in only one Hunt Group.
There are three types of Extension Hunting:
Circular Hunting 
A Circular Hunt Group consists of extensions programmed into an ordered circular
list, where the first and last extension are the same (e.g., 304, 305, 306, 307, 304).  If
a call is unanswered at one extension, it moves to the next extension in the list.  If
still unanswered, it rings all remaining members, circling back to the top of the list if
necessary.  If not picked up after ringing all group members: 
·An Intercom call continues to ring the last extension in the group 
·An outside call rings all extensions programmed for ringing on that line (an un-
answered Transfer call may recall the transferer before ringing the other exten-
sions)
Terminal Hunting 
A Terminal Hunt Group consists of extensions programmed into a ordered list (e.g.,
304, 305, 306, 307).  If a call is unanswered at one extension, it moves to the next
extension in the list.  If still unanswered, it rings the remaining members until it
reaches the bottom of the list; it does not circle back to the top of the list.  If still
unanswered: 
·An Intercom call continues to ring the last extension in the group 
·An outside call can ring the attendant or all extensions programmed for ringing
on that line (an unanswered Transfer may recall the transferer before ringing the
other extensions)
Extension Hunting
Part I:  DIGITAL SYSTEM Features 81 
						

							Uniform Call Distribution (UCD)
A UCD Hunt Group consists of extensions programmed into a list, and the group is
assigned a master extension number.  The UCD Hunting process begins when a call
comes into the master extension number (such as a call transferred to the master number).
The order in which the call rings the member extensions depends on how busy the
extensions have been.  The first extension rung is the one that has been idle the longest.
The last extension rung is the one that has been busiest. If all UCD members are busy, the
call waits (Camps-On) for the programmed Camp-On time, then moves to the overflow
extension (if any).  If not answered at the overflow extension, a waiting outside call rings
all extensions programmed for ringing on that line.
Notes: 
·Hunt Groups can be linked together.  For example, a UCD master number can be
the last member of a Terminal Hunt Group, or the overflow for another UCD
Hunt Group.
·Activating at a Hunt Group extension disrupts normal hunting. 
·Activating DND at a Hunt Group extension temporarily removes it from the
group.  If a Circular extension is in DND, an outside call continually cycles
through the group. 
·Two attendants (e.g., 307, 304) can be in a circular Hunt Group for special Night
Answer operation (the group = 307, 304, 307 with type 02).  Both attendants
must activate Night Answer to put their lines into the Night Answer mode. 
·Automatic Call Distribution is similar to UCD Hunting, but with unique supervi-
sor and agent features.  Refer to page 36 for the specifics.
·Extension Hunting considers an extension in DND to be busy. This may disrupt
normal hunting.

							Exte rna l Alerting De vice
&
The ringing for incoming calls is amplified so it can be heard in
large noisy areas, such as a machine shop.
An External Alerting Device, such as a bell, can be connected to Relay 01 (located in
the Main CEU) and Relay 02 (located in Expansion CEU #1).  You can program the
system so that a relay activates and the bell rings when an incoming call rings one of
the following destinations: 
·A line (348-363) 
·An extension (300-347)
·A Ring Group (364-371 without AUX, 396-403 with AUX) 
The relay activates for day and Night Answer calls with one exception:  If you select
extension 300 for a relay, the relay activates only for calls that ring extension 300
while it is in the Night Answer mode.  You can also program the relays to have a
steady or interrupted closure, depending on what the External Alerting Device
requires.
An External Alerting Device must be compatible with the following relay
specifications: 
Maximum Load 60 mA @ 30 Vdc
10 mA @ 90 Vdc
Initial Configuration 
·Relays 01 and 02 activate when a call rings extension 300 during the Night
mode 
·Relays 01 and 02 are programmed for steady closure
