PART 1. SYSTEM OVERVIEW

1.1 SIZE AND CONFIGURATION

The DCS 50si is a digital ISDN compatible telephone system designed for small busi­nesses. It can operate with the functionality of a square key system, PABX or a combina­tion of both (hybrid). The DCS 50si employes the very latest DSP (Digital Signal Proces­sor) digital technology.

The DCS 50si offers a variety of interface cards that allow connection to the public tele­phone network or to private networks. These are generally referred to as trunk cards. Two
types of telephones can be connected to the system. Proprietary digital phones called
“keysets” connect to digital line interface cards (DLI). Standard telephones generally called
“single line sets” connect to single line interface cards (SLI). In addition, DLI station ports
are used to connect peripheral devices such as door phones and add-on modules. Mis­cellaneous circuits are provided to allow such optional features as external paging, music
on hold, background music, common audible devices, alarms and emergency power fail­ure telephones.

All DCS keysets utilize a single PCB with surface-mounted components assuring the highest
product quality and long life. Samsung’s customary large, easy-to-read displays and LEDs
in the button design make them much easier to use. In many instances, sophisticated
features are made simple through the use of friendly display prompts or push-on/push-off
feature keys.

CONTENTS

Expanding the DCS 50si system is both economical and easy. Begin with the basic Key
Service Unit and then add an expansion cabinet as your business grows (

1). The KSU has 8 keyset ports and 3 universal card slots that can be used for stations,

trunks or 2x4 combination cards. In addition, the KSU has dedicated slots for a 2SLI card
and a miscellaneous function card. The expansion cabinet adds a further 3 universal slots
and a dedicated slot for a CADENCE CVM8A card. The systems low density card design
allows greater flexibility when configuring a system for the right combination of lines and
stations. A removable memory card (SMEM2 card) makes it convenient to upgrade to
future feature packages as well as providing quick and easy servicing. The maximum

quantities of the various station and trunk types can be seen in the table 1–1.

TABLE 1–1

CONTENTS

1. A maximum of 40 stations can be installed on the system.

2. Only one 2 SLI card can be installed in the system.

3. Only one SMISC card can be installed in the system.

4. Up to six expansion cards can be installed in the system.

5. Only one CADENCE card can be installed in the system.

6. Installing CADENCE reduces the maximum number of stations to 32.

7. Only eight KDbs can be installed in the system and they must be installed on keysets
connected to the (8) eight 2B+D ports on the KSU motherboard.

1.2 TECHNOLOGY

System switching is accomplished by means of a custom IC “engine” that provides 128
switchable digital channels. Each of the 128 digital channels is automatically assigned to
carry voice or data as required by system operation in a PCM format. In addition to the 128
channels mentioned above , the system also utilizes Digital Signal Processors or DSPs.
Each DSP may be configured by the switching control program as a DTMF receiver or a
C.O. tone detector on a per-call basis. The engine chip contains four DSPs and four more
are added when an SMISC card is installed. This means that the system contains a total
of eight DSP channels when fully expanded. The DSP channels are fully shared through­out the system as a common resource.

MEMORY

The system operates using stored program control. This program is stored in four EPROM
chips (2048 Kbytes of memory). All specific customer data is stored in non-volatile ran-

1.4

dom access memory (NV-RAM) located on the removable SMEM2 card. It is protected by
a super capacitor providing seven days of memory protection in the event of loss of AC
power to the system.

MICROPROCESSORS

The DCS 50si uses distributed processing. The system’s primary processor is a 16 bit
Motorola® MC68000 operating at a clock speed of 16MHz. The secondary level of pro­cessing is done in the keysets.

1.3 PROGRAMMING

The DCS 50si comes with default data. This data provides for operation within seconds
after applying power. All trunks and stations are assigned according to the default num­bering plan. This numbering plan is flexible and may be changed if so desired. The tech­nician customizes this default data to meet the end user’s requirements.

The system can be programmed from any display keyset without interrupting normal sys­tem operation. There are three levels of programming: TECHNICAL, CUSTOMER and
STATION. The technician level has access to all programs and can allow the customer
access to system programs as needed. Technician and customer access are controlled
by different security passcodes.

CONTENTS

The DCS 50si also allows the use of a proprietary computer program called PCMMC. This
permits a technician to program the system using a personal computer. PCMMC can be
used on-site to modify the customer database or to download (save) the entire customer
database to a file. This file can then be saved as a backup and uploaded when required to
restore the database.

Through the use of modems, PCMMC can access a DCS 50si system remotely (off-site)
to make database changes or perform uploads or downloads of the customer database
as if the technician were on-site.

cards. These S/T circuits can be configured for station or trunk use. An NT1 is required
for connection to a telephone company BRI circuit. The BRI card requires that an SPLL
daughter board be installed in the KSU.

SPLL Daughter Board

This daughter board is required to provide clocking for the S4BRI card. If an S4BRI card
is to be installed an SPLL daughter board must also be installed.

NOTE: Only one SPLL daughter board is required per system however many S4BRI
cards are installed.

SMISC1

This card provides a second MOH/BGM input, three general purpose relays, an alarm
sensor, two serial I/O ports, caller ID decoding circuits, and four DSP circuits. It is recom-

mended that this card be used in situations requiring heavy single line telephone use.

CONTENTS

CADENCE (CVM8A)

The CADENCE Voice Mail system is a fully integrated Auto Attendant/Voice Mail/Fax
System on a single DCS circuit card (see Figure 2–4). This optional card is designated
the CVM8A and provides 4 or 8 channels of communication. Only one card is permitted
per system and it is installed in a dedicated slot in the expansion cabinet.

2.3

This fully featured self contained system is connected
directly to the DCS 50si data bus and communicates
with the DCS 50si system processor. This design means
that installation time is minimized, operation is stream­lined and many features can be implemented that are
not normally possible with older conventional stand
alone Voice Mail/Auto Attendant systems.

All power to run this self contained system comes from
the DCS 50si telephone system power supply. The DCS
50si power supply is rated according to the number of
stations it will support. When CADENCE is installed it
counts as (8) eight stations of the PSU rating regard­less of the number of Voice Processing Modules in­stalled.

4.1.1

4.1 SYSTEM FEATURE DESCRIPTIONS

ACCOUNT CODE ENTRY

Station users may enter an account code (maximum 12 digits) before hanging up
from a call. This account code will appear in the SMDR printout for that call record.
Keyset users may enter this code using an account (ACCT) key without interrupt­ing a conversation. Single line telephone users must temporarily interrupt the call
by hook-flashing and dialing the feature access code. Account codes can be up to
12 digits long.

FORCED

When forced, they are always verified from a system list of 500 entries. Account
codes are always printed on the SMDR report. They can contain digits 0–9.

VOLUNTARY

Users may elect to enter an account code for any call. They can include digits 0–9,
star (3) and #.

ALL CALL VOICE PAGE

Users can page all internal and all external paging zones at the same time by
dialing the All Page code. Keysets may be restricted from making or receiving
pages in system programming. A maximum of 40 keysets can be programmed to
receive page announcements.

CONTENTS

ATTENTION TONE

To get your attention, a brief tone precedes all page announcements and intercom
voice calls. There are separate programmable duration timers for page and voice
announce tones.

AUTHORIZATION CODES

Authorization codes are used to give permission to make a call. These four digit
authorization codes can be either forced or voluntary. When used, authorization
codes will automatically change the dialing station’s class of service to the level
assigned to the authorization code. Authorization codes may be programmed to
print or not print on SMDR.

FORCED

When a station is programmed for forced authorization, the user must always enter
this code before dialing is allowed. The dialed authorization code is verified from a
system list of 250 entries.

VOLUNTARY

Any station user can always enter an authorization code before they begin dialing.
The dialed authorization code is verified from a system list of 250 entries.

4.1.2

AUTO ATTENDANT

The SMISC2 card for the DCS 50si includes four ports of auto attendant for simul­taneous answering and call processing. Sixteen professionally recorded prompts
inform callers of the progress of their calls. Several examples are the following: “I’m
sorry. There is no answer”, “That station is busy” and “Invalid number. Please try
again”, Two minutes of battery-backed random access memory (RAM) provide up
to 48 customer recordings for announcements or greetings. Twelve individual greet­ing boxes, each with its own dialing options, allow you to build call routing branches
as needed. Callers are routed through the branches by dialing extension numbers
or single digits.

NOTE: Requires optional hardware and/or software. Ask your dealer for details.

AUTOMATIC HOLD

While a keyset user is engaged on an outside (C.O.) call, pressing another trunk
key, route key or CALL button automatically places the call on hold when Automatic
Hold is enabled. Pressing TRSF, CONFERENCE, PAGE or a DSS key always
automatically places a C.O. call on hold. Intercom calls can be automatically held
only by pressing TRSF or CONFERENCE. Each keyset user can enable or disable
Automatic Hold.

CONTENTS

BACKGROUND MUSIC

Keyset users may choose to hear music through their keyset speakers when op­tional external sources are installed. Each user may adjust this level by the use of
a volume control program at the selected keyset.

CALLER IDENTIFICATION

CALLER ID

Caller ID requires that optional software and hardware be installed in the DCS 50si
KSU. In addition, Caller ID service must be provided by your local telephone com­pany. The availability of the calling party name or number depends on the type of
CID service offered by your local telephone company. The Caller ID feature is de­pendent on having an LCD keyset to show the name or number in the top line of the
display. NOTE: Requires optional hardware and/or software. Ask your dealer for
details.

NAME/NUMBER DISPLAY

Each LCD keyset user can decide if he/she wants to see the CID name or CID/ANI
number in the display. Regardless of which one is selected to be seen first, the N/N
key is pressed to view the other pieces of CID information.

NEXT CALL

In the event that you have a call waiting or a camped-on call at your keyset, you can
press the NEXT key to display the Caller ID information associated with this next

4.1.3

call in queue at your station. Either the CID name or CID number will show in the
display depending on your N/N selection.

SAVE CID

At any time during an incoming call that provides CID information, you may press
the SAVE key. This saves the CID number in the Save Number feature. Pressing
the SAVE number redial key will dial the CID number. The system must be using
Least Cost Routing (LCR) to dial the saved number.

STORE CID

At any time during an incoming call that provides CID, you may press the STORE
key. This saves the CID number as a speed dial number in your personal speed
dial list. The system must be using LCR to dial the stored number.

INQUIRE PARK/HOLD

Having been informed that an incoming call is on hold or has been parked, you may
view the Caller ID information before you retrieve the call. This will influence how
you choose to handle the call.

CID REVIEW LIST

This feature allows display keyset users to review CID information for calls sent to
their stations. This list can be from ten to fifty calls in a first in, first out basis. The list
includes calls that you answered and calls that rang your station but that you did
not answer. When reviewing this list, you can press one button to dial the person
back. The system must be using LCR to dial the stored number.

CONTENTS

INVESTIGATE

This feature allows selected stations with a special class of service to investigate
any call in progress. If CID information is available for an incoming call, you will
know to whom this station user is speaking. On outgoing calls, you can see who
was called. After investigating, you may barge-in on the conversation, disconnect
the call or hang up.

ABANDON CALL LIST (50)

The system has a system-wide abandon call list that stores CID information for the
last 50 calls that rang but were not answered. The list is accessed using the operator’s
passcode. When reviewing this list, you are provided options to CLEAR the entry or
DIAL the number. You can use the NND key to toggle between the CID name, CID
number and the date and time the call came in. The system must be using LCR to
dial numbers from the abandon call list.

CID ON SMDR

The Station Message Detail Records report can be set to include CID name and
CID number for incoming calls. This format expands the printout to 113 characters.
Use a wide carriage printer or an 80 column printer set for condensed print.

4.1.4

NUMBER TO NAME TRANSLATION (350)

The system provides a translation table for 350 entries. When the CID number is
received, the table is searched. When a match is found, the system will display the
corresponding name. This will allow users in areas that do not support deluxe Caller
ID to provide names for regular callers.

CALL FORWARDING

This feature allows the user to redirect (forward) incoming calls. The calls can be
redirected to the attendant, a hunt group, voice mail, external number or another
station user. If the destination station is in Do Not Disturb (DND), the calling party
will receive DND/Reorder tone. Calls cannot be forwarded to a door phone.

ALL CALLS

This type of forwarding is not affected by the condition of the station. All calls are
immediately redirected to the designated destination. If desired, the destination
station may redirect the call back to the forwarded station by using the transfer
feature. The forwarded station user can continue to originate calls as usual. If no
key is programmed as Forward All, the TRSF key lights steady when a Forward All
condition is set.

CONTENTS

BUSY

This feature forwards all calls only when the station set is busy. The station user
can originate calls as usual.

FORWARD DND

This feature works with the Do Not Disturb feature. This allows calls directed to a
station in Do Not Disturb or One Time Do Not Disturb to forward immediately to
another destination.

NO ANSWER

This feature forwards calls that are not answered within a preprogrammed time.
The user can originate calls as usual and receive calls if present. The timer is
programmable on a per-station basis to allow for differences in individual work
habits.

BUSY/NO ANSWER

This feature allows the station user to use both types of forwarding simultaneously,
provided the destinations have already been entered in the usual manner.

FOLLOW ME

This feature allows the user to forward all calls from another station to the user’s
station or change the forward destination to the user’s current location.

4.1.5

EXTERNAL

This feature forwards C.O. calls to an external number via a central office trunk if
allowed by class of service. These C.O. calls forward only after the programmable
external call forward delay timer expires.

TO VOICE MAIL

Each station may be programmed to allow or deny the ability to forward intercom
calls to voice mail. When denied, valuable message time in the voice mail system
can be saved.

CALL HOLD (EXCLUSIVE)

Outside calls can be placed on exclusive hold at any keyset by pressing HOLD twice
during a call. Calls placed on exclusive hold can only be retrieved at the keyset that
placed the call on hold. Intercom calls are always placed on exclusive hold.

CALL HOLD (SYSTEM)

Outside calls can be placed on system hold at any station. Users may dial the
access code or press the HOLD button. Calls on system hold may be retrieved at
any station.

CALL HOLD (REMOTE)

CONTENTS

Outside calls can be placed on hold at a remote station. This feature allows calls to
be answered at one keyset and placed on hold at another station. This allows time
for the user to proceed to that station or allows the party that the call was intended
for to have that call placed at their station. The call or trunk button will flash at the
remote hold station.

CALL PARK AND PAGE

Each C.O. line has its own park zone. This simple method eliminates confusion
and ensures that a park zone is always available. Pressing the PAGE key parks the
call automatically. There are no extra buttons to press and there is no lost time
looking for a free zone.

CALL PICKUP

DIRECTED

With directed call pickup, users can answer calls ringing at any station by dialing a
code plus that station’s extension number or by pressing the feature button and
then dialing the extension.

GROUPS (20)

In addition, calls can be picked up from a station group in a similar manner. The
group pickup feature allows users to answer any call ringing within any pickup
group. There are 20 pickup groups available. A station cannot be in more than one
pickup group. To use this feature, station users either dial the access code or press
the assigned feature button followed by the pickup group number.

4.1.6

CALL WAITING/CAMP-ON

Busy stations are notified that a call is waiting (camped-on) when they receive a
tone. The tone is repeated at a programmable interval. Keysets receive an off-hook
ring signal through the speaker and single line stations receive a tone in the hand­set. The volume of the camp-on tone can be set by the station user. Camped-on
calls follow Forward No Answer if a Forward No Answer destination has been set.

CENTREX/PBX USE

CENTREX and PBX lines can be installed in lieu of central office trunks. CENTREX
and PBX feature access codes including the command for hook-flash (FLASH) can
be stored under one touch buttons. Toll restriction programming can ignore PBX or
CENTREX access codes so that toll calls can be controlled when using these ser­vices.

CHAIN DIALING

Keyset users may manually dial additional digits following a speed dial call or chain
together as many speed dial numbers as are required.

CLASS OF SERVICE

The system allows a maximum of 30 station classes of service. Each class of
service can be customized in memory to allow or deny access to features and to
define a station’s dialing class. Each station can be assigned different classes of
service for day and night operation.

CONTENTS

COMMON BELL CONTROL

Each MISC card is equipped with three programmable relays. A relay program­mable relays. A relay programmed as a common bell provides a dry contact pair to
control a customer-provided bell or common audible device. These contacts must
be programmed as members of a station group and may provide steady or inter­rupted closure.

CONFERENCE

The system allows six simultaneous conferences.

ADD-ON (5 PARTY)

Any combination of up to five parties (stations or outside lines) can be joined to­gether in an add-on conference. Parties may be eliminated or added after a confer­ence has been established.

UNSUPERVISED

A station user may set up a conference with two or more outside lines and then exit
the conference leaving the outside lines connected in an unsupervised (trunk to
trunk) conference.

4.1.7

COMPUTER TELEPHONY INTEGRATION (CTI)

Computer Telephony Integration (CTI) allows integration between the DCS 50si
and a personal computer system (PC) or a local area network (LAN). Caller ID
service is required on TAPI and TSAPI inbound call applications that use the CID
information to display computer records in conjunction with the presentation of the
call to the station on the DCS 50si system. TAPI and TSAPI are described below.

TAPI

Jointly developed by Intel and Microsoft, TAPI (Telephony Applications Program­ming Interface) delivers telephony features to the Windows desktop. TAPI is an
open application interface (OAI) protocol that supports First Party Call Control. A
DCS Computer Telephony Module (CTM) is required to connect any keyset to a
personal computer running Windows 3.1 or Windows 95. The number of CTMs
that can be installed on a system is only limited by the number of keyset ports. The
features and functionality of the keysets are not changed.

TSAPI

Telephony Services Application Programming Interface (TSAPI) was developed by
Novell and AT&T and is the method of integrating the DCS 50si system to a com­puter. TSAPI is a LAN based solution allowing computers to communicate directly
to the telephone system over the network system. This establishes a logical con­nection rather than a physical connection between telephone and computer. It elimi­nates the cost and administrative overhead of connecting every PC to a desktop
phone. It emphasizes third-party call control. (Example: calls can be tracked as
they are transferred, making it more suited to large office applications). TSAPI can
emulate first-party type call control for the DCS 50si, rather than from the tele­phone as TAPI does. For example, to make a call, the DCS 50si, rather than the
telephone would dial the phone number, and the call would then be transferred to
the telephone. Novell Telephony Services 2.1 or higher specifies the data commu­nications link between the Novell Netware file server running the Netware Tele­phony Services NLM and the Samsung DCS 50si. The physical connection from
the Novell Telephony server to the DCS 50si is an EIA-232 connection an I/O port
on the SMISC card.

CONTENTS

CTI SYSTEM LINK

The DCS 50si has a system wide CTI link. This CTI link is provided from one of the
serial I/O ports on the SMISC and can be used with either the DCS TSAPI driver to
connect the system to a Novell LAN or the TAPI 2.0 driver to provide a CTI link to a
Windows NT server based LAN environment.

CUSTOMER SET RELOCATION

Customer Set Relocation allows the customer to exchange or swap similar stations
in the DCS 50si without wiring changes. All individual station assignments such as
trunk ring, station group, station COS, station speed dial, button appearances, call
forwarding, etc. will follow the Customer Set Relocation program.

4.1.8

DATA SECURITY

Single line extensions used with modems and facsimile machines can be pro­grammed so that they will not receive any system-generated tones that would dis­rupt data transmissions. In addition, these devices receive DCS C.O. ringing pat­tern instead of intercom ring pattern. Devices connected to an SLI card receive a
disconnect signal upon termination.

DATABASE PRINTOUT

A copy of the customer database can be obtained by using PCMMC. This informa­tion can be directed to a printer or the PC screen and may be done either on-site or
remotely. A complete database or specific data blocks may be obtained.

DIALED NUMBER IDENTIFICATION SERVICE (DNIS)

When DNIS service is provided on an incoming E&M trunk the DCS 50si can route
calls based on the numbers received.

DIRECT IN LINES

Outside lines may be programmed to bypass the operator(s) and ring directly at
any station or group of stations.

DIRECT INWARD DIALING (DID-USE E&M TRUNK)

CONTENTS

The DCS 50si can use local telephone company-provided DID service via an E&M
trunk. When programmed, anyone dialing a user’s personal number rings directly
to that user’s office. DID calls to a busy station have the option to return busy signal
to the C.O. or return ringback to the C.O. When ringback is selected, the called
station receives off-hook ring. Multiple DID numbers can ring the same extension
or station group and display keysets show a DID directory name when ringing if a
name has been programmed. DID calls can be assigned both a day and night ring
destination. This allows routing of DID calls that have one destination during the
system Day mode to be routed to a different destination during the system Night
mode. DID calls that are directed to ring a voice mail machine can be identified by
a special digit (see Voice Mail Integration). As it is possible to program E&M trunks
to follow the DID translation tables, the system can use both way DID type service.

DIRECT INWARD SYSTEM ACCESS (DISA)

Users can call in on specific DISA lines at any time, input a security code and
receive system dial tone. Users can now place internal calls or if permitted, calls
using C.O. lines. The caller must have a tone dial phone and know his/her DISA
security code. DISA lines can be used as both way lines or incoming only and may
be active in day mode, night mode or both. The C.O. lines used for DISA must have
disconnect supervision.

DIRECT TRUNK SELECTION

Each station can be allowed access to or denied access from a trunk or trunk group
by access code when LCR is activated. When restricted, the station user must use
a trunk key or a route key.

4.1.9

DIRECTORY NAMES

Each station, station group and C.O. line may be assigned a directory name (maxi­mum 11 characters). In addition, each personal speed dial number, system speed
dial number and entry in the DID translation table may be assigned a name (maxi­mum 11 characters). These names are displayed during calls with these ports and
in the case of station and speed dial names, can be used to originate calls. See the

Dial by Name feature (Station Features).

DISA SECURITY

Telephone fraud and long distance theft continue to increase; therefore, we have
introduced a DISA security system. If an incorrect DISA passcode is entered re­peatedly (as is the case with “hackers”), the DISA system can be automatically
disabled temporarily. Both the number of incorrect passcode attempts and the time
that DISA is disabled are programmable. In addition, all failed attempts to access
DISA print on SMDR (if provided) with a “DE” DISA error flag.

DISTINCTIVE RINGING

A user knows the type of call received by the type of ring heard. Outside calls have
a single ring repeated while internal calls have a double ring repeated.

DOOR LOCK RELEASE (PROGRAMMABLE)

CONTENTS

After answering a call from the door phone, users can dial a code to activate a contact
closure. This can be used to operate a customer-provided electric door lock release
mechanism. The contact closure timer is programmable from 100–2500 ms.

DOOR PHONES

The door phone interface module (DPIM) provides for connection of a door phone
to a DLI port. Pressing the button on the door phone produces a distinctive ring
(three short rings repeated) at the assigned station or station group. If not an­swered within a programmable time, the system releases the door phone and stops
the ringing. Stations may call the door phone directly and monitor the surrounding
areas.

DOOR PHONE NIGHT RING

The ring destination of door phone calls may be different at night than during the
day. For example, large factories may want these calls directed to a security desk
after hours.

E & M TIE LINES

Your office can be connected to another office with a tie line. Use it to make calls to
stations in the other system. If programming allows, you can access lines in the
other system to make outside calls. Tie line calls can be put on hold, transferred
and conferenced in the same way as are other outside calls. Users accessing the
tie line from the other system can get a line in your system and make outgoing
calls. These calls can be controlled by assigning a dialing class to the tie line. Your

4.1.10

local telephone company may use E&M tie lines to provide DID service. In this
case these tie lines can be programmed to follow the DID translation table. See

DID. Translated E & M tie line calls have Day and Night routing capabilities.

EXECUTIVE BARGE-IN (OVERRIDE)

The feature allows specially programmed stations with a barge-in key to override
the automatic privacy of another station or outside trunk. Programming allows barge­in with or without a warning tone. Stations may also be programmed as “secure” so
that they cannot be barged-in on.

WITH WARNING TONE

When the barge-in with tone option is set, the barging-in keyset has its microphone
on and the barged-in on station receives an override display. A double burst of
warning tone sounds and repeats every ten seconds. This feature does not work
from single line sets.

WITHOUT WARNING TONE

When the barge-in without tone option is set, the barging-in keyset has its micro­phone muted and the barged-in on station does not receive an override display.
This feature does not work from single line sets.

CONTENTS

WARNING: BARGE-IN WITHOUT TONE MAY VIOLATE STATE OR FEDERAL
LAWS CONCERNING THE RIGHT TO PRIVACY. SAMSUNG TELECOMMUNI­CATIONS AMERICA IS IN NO WAY RESPONSIBLE FOR THE POSSIBLE MIS­USE OF THIS FEATURE.

EXECUTIVE/SECRETARY POOLING

Each keyset may be defined as a BOSS or a SECRETARY in system program­ming. Each BOSS can have up to four SECRETARIES and each SECRETARY
can have up to four BOSSES. These arrangements are known as executive/secre­tary pools. There can be multiple pools in a system. When a BOSS is in DND, all
calls to the BOSS ring the first SECRETARY assigned to that BOSS; if that SEC­RETARY is busy, the call hunt to the next available SECRETARY assigned to that
BOSS. If the SECRETARY must communicate with the BOSS while he/she is in
DND, pressing the corresponding BOSS button on the SECRETARY’s keyset re-
sults in an Auto Answer intercom call being made to the BOSS (providing the BOSS
is free). A station can only be the BOSS of one SECRETARY pool. In addition, a
station cannot be in more than one pool.

EXTERNAL MUSIC INTERFACES

The system provides an interface for connecting a customer-provided external music
source and the addition of an SMISC card provides a second interface. These
interfaces can be used for background music, station music on hold or trunk music
on hold.

4.1.11

EXTERNAL PAGE INTERFACE

The system KSU provides one external page audio output. The addition of an SMISC
card will provide a second audio output and three general purpose relays that may
be assigned to control paging zones. Multiple relays may be assigned to a page
zone.

FLASH KEY OPERATION

While a user is on an outside line, pressing the FLASH key will flash the central office
or PBX. This is used for custom calling features on C.O. lines or in conjunction with
CENTREX/PBX operation. System programming allows individual flash times for C.O.
and PBX lines. When C.O. or PBX flash is not required, setting the timers for two
seconds releases the existing call and returns dial tone to make a new call.

FLEXIBLE NUMBERING

System programming allows stations to have two, three or four digit extension num­bers beginning with the digit 2 or 3. Default extension numbers begin with 201.
Station hunt group access codes can be two or three digits beginning with the digit

5. These can be changed but it will affect other feature access codes. All user
guides are written using the default numbering plan.

FLEXIBLE RINGING

CONTENTS

Each C.O. line can be programmed to ring at any station or station group. Each line
can be assigned a day ring destination and a night ring destination.

HOT LINE

Stations can be programmed to call a pre-defined station or station group when­ever that station goes off-hook. A hot line delay timer of 1–250 seconds can be
programmed to allow sufficient time to make a different call.

IN GROUP/OUT OF GROUP

Individuals assigned to a station hunt group may temporarily remove their tele­phones from the group by pressing the In/Out of Group button providing that there
is someone still in the group. Stations out of a group will not receive calls to that
group but will continue to receive calls to their individual extension numbers. When
desired, the user may put him/herself back into the group by pressing the button
again. Users who do not have this button may dial the access code and the group
desired. A station user is allowed to be in several groups, providing a key and the
extender of that group are assigned for each group on the user’s phone.

INCOMING CALL DISTRIBUTION

Incoming calls can be assigned to ring a distributed station hunt group. This allows
all members of the group to share the call load.

4.1.12

INCOMING/OUTGOING SERVICE

Outside lines are available for incoming or outgoing service. Programming allows
any outside line to be used for incoming calls only, outgoing calls only or both way
service.

INDIVIDUAL LINE CONTROL

Each station in the system can be individually programmed to allow or deny dialing
out as well as allow or deny answering for each outside line.

INTEGRATED SERVICES DIGITAL NETWORK (ISDN) INTERFACE

The DCS 50si supports ISDN Basic Rate Interface (BRI) in both station and trunk
formats. The S4BRI card for the DCS 50si consists of four circuits each of which
can support two channels for a total of eight channels per card. The DCS 50si can
support a maximum of 6 BRI cards giving a total of twenty-four circuits or 48 chan­nels.

An SPLL daughter board must be installed in the system to provide clocking for the
BRI cards.

TRUNK INTERFACE
When configured as a trunk a BRI circuit will support the following protocols:

CONTENTS

l National ISDN 2
l AT&T 5ESS Custom
l Nortel DMS 100 Custom

INTEGRATED VOICE MAIL

The DCS 50si has a dedicated slot in the expansion cabinet to contain a CADENCE
(VM8A) card. This card can be used with both four ports and eight ports (one or two
Voice Processing Modules installed). This will allow such features as Call Record,
Answering Machine Emulation and Soft Key mailbox administration. NOTE: Install­ing the CADENCE board reduces the maximum number of stations on the system
to 32.

LEAST COST ROUTING

Least Cost Routing (LCR) is the ability to automatically select the most cost effec­tive central office route for the outside number dialed by any station. The DCS 50si
LCR program includes the following features:

l Option to use or not use LCR or a tenant basis
l Programmable LCR access code
l Digit analysis table 1000 entries each with ten digits
l Routing by time of day and day of week (4 time bands per day)
l Routing according to individual station class
l Modify digits table 100 entries
l Flexible trunk group advance timer
l Option to use or not use trunk group advance warning tones

4.1.13

LIVE SYSTEM PROGRAMMING

The system can be programmed from any display keyset or personal computer
without interrupting normal system operation. There are three levels of program­ming: technician, customer and station. The technician level has access to all pro­grams and can allow the customer access to system programs as needed. Techni­cian and customer access are controlled by different security passcodes. Program­ming from a PC requires the PCMMC program.

MEET ME PAGE AND ANSWER

After a user makes a Meet Me Page, the user may remain off-hook to allow the
paged party to meet the user for a private conversation.

MEMORY PROTECTION

In the event that power is lost to the system, all customer data contained in memory
is retained by the use of a “super capacitor” for approximately seven days. In addi­tion, the PCMMC computer program may be used to produce a backup copy of the
customer data.

MESSAGE WAITING INDICATIONS

When calling a station and receiving a busy signal or the no answer condition, the
caller can leave an indication that a message is waiting. The message button will
flash red at the messaged keyset. A single line phone will receive a distinctive
message waiting dial tone. Five message waiting indications can be left at any
station.

CONTENTS

MICROPHONE ON/OFF PER STATION

The microphone can be disabled at any keyset. When the microphone is disabled,
the keyset cannot use the speakerphone, although on-hook dialing and group lis­tening are still possible.

MUSIC ON HOLD—FLEXIBLE

When external music sources are connected, each C.O. line may be programmed
to receive one of the two external sources, internally-generated tones or no music
when it is placed on hold. If there are no sources installed, each line may receive
either a 50 ms tone or no music. The system-generated tone is a beep every 3.5
seconds.

NIGHT SERVICE

The DCS 50si provides separate ringing locations for all trunks in both the day and
the night modes.

AUTOMATIC

Automatic night service allows each tenant to automatically go in and out of night
service according to the system clock. There are separate time options available
for each day of the week. This feature can be overridden by a manual night service
key and passcode.

4.1.14

MANUAL

The operator presses the NIGHT key and then dials a passcode to change day
mode to night mode operation.

OFF PREMISES EXTENSIONS (OPX)

A single line (tip and ring) extension from an SLI card may be connected to tele­phone company-provided OPX circuits to remote locations. 8SLI cards and KDb­SLIs do not support off premises extensions.

OPERATOR GROUP

The operator group can contain 32 stations to answer incoming calls. Calls to this
group can be set for distributed, sequential or unconditional ringing. Operators can
use the In/Out of Group feature to meet flexible operator requirements.

OVERFLOW

OPERATOR

When calls ringing a operator group go unanswered, they can overflow to another
destination after a programmed period of time. The operator group has its own
timer. The overflow destination can be a station or station group.

CONTENTS

STATION GROUP

When calls ringing a station group go unanswered, they can overflow to another
destination after a programmed period of time. Each station group has its own
timer. The overflow destination can be a station or station group.

PAGING

System software allows the use of four internal and four external paging zones.
Stations can page any individual zone, all internal zones, all external zones or all
zones simultaneously. Using system programming, each station may be allowed or
denied the abilities to make and/or receive page announcements to any zone or
combination of zones.

POWER FAILURE TRANSFER

Each S3TRK card is equipped with two power fail relays. If power fails, these relays
can be used to reroute the first two C.O. lines on the card to single line telephones.
When power is restored to the system, the lines and stations return to normal
operation and calls in progress will be disconnected.

PRIME LINE SELECTION

Any station can be programmed to select a specific line, line group, telephone
number, station or station group.

PRIVATE LINES

For private line use, stations can be prevented from dialing and/or answering any line.

4.1.15

PROGRAMMABLE LINE PRIVACY

Each outside line can be programmed to ignore the automatic line privacy. This
allows up to four other parties to join your conversation by simply pressing the line
button. This is similar to 1A2 key telephone operation.

PROGRAMMABLE TIMERS

There are over 50 programmable system timers to allow each installation to be
customized to best fit the end user’s application.

RECALLS

Calls put on hold, transferred or camped-on to any station will recall to the originat­ing station if not answered within a programmable time. A recall that goes unan­swered for the duration of the attendant recall timer will recall to the system opera­tor group. Hold, transfer, camp-on and attendant recalls have individual program­mable timers. Calls recalling to buttons with tri-colored LEDs will flash amber.

REMOTE PROGRAMMING—PC

Remote programming allows the technician to access the system database from a
remote location for the purpose of making changes to the customer data. Cus­tomer-provided modems and a PC using an optional software package will be needed
to implement this feature.

CONTENTS

RING OVER PAGE

Any outside line can be programmed to ring over a customer-provided paging sys­tem. Outside lines, door phones and station groups may ring over page in the day
or night mode.

SINGLE LINE CONNECTIONS

Single line ports allow connection of a variety of single line telephones plus fac­simile machines, answering machines, loud bells, computer modems, cordless
phones and credit card machines. When connecting customer-provided equipment
to these extensions, compatibility should be checked out before purchase to en­sure correct operation. Central office ring cadence can be selected for SLT sta­tions. This is helpful when optional devices cannot detect DCS intercom ring ca­dence.

SPEED DIAL NUMBERS (1500)

A library of 1500 speed dial numbers may be allocated as needed. The system list
can have up to 500 numbers and each station can have up to 50 numbers. Speed
dial numbers are assigned in blocks of ten. Each speed dial number may contain
up to 18 digits.

SPEED DIAL BY DIRECTORY

The DCS 50si system provides the user with the ability to look up a speed dial
number and place the call. There are three speed dial selections: personal, system

4.1.16

and station. This feature can be used with the soft keys on the display keysets or as
a programmable button.

STATION HUNT GROUPS (30)

System programming allows up to 30 station hunt groups. One of three ring pat­terns—sequential, distributed and unconditional—is available for each group. Each
unconditional group may contain a maximum of 32 stations. A station may be as­signed to more than one group. The default directory numbers to call these groups
are 501–529. Group 500 is reserved for the operator group and is called by dialing
“0.” Each station group has its own recall timer for calls transferred to that group.

STATION MESSAGE DETAIL RECORDING (SMDR)

The system provides, via an optional SIM, records of calls made, received and
transferred. Connecting a customer-provided printer or call accounting system will
allow collection of these records. Each call record provides the following details:
station number, outside line number, start date, start time, duration of call, digits
dialed (maximum 18) and an account code if entered. The system may print a
header followed by 50 call records per page or send continuous records with no
header for use with a call accounting machine. See the sample printouts.

The SMDR format contains many options that allow it to be customized for a
company’s individual needs. Options to print include incoming calls, outgoing calls,
in and out of group status, change in DND status and authorization codes.

CONTENTS

SYSTEM ALARMS

The basic KSU has an alarm sensor pair, when this pair is short-circuited, the
system will ring a preprogrammed destination with a customized display message.
The alarm destination can be a station or station group.

A DISA alarm will warn the customer if the DISA security system has been trig­gered by too many incorrect password attempts. The alarm can ring any station or
group of stations and show an appropriate display at the assigned stations.

SYSTEM DIRECTORY

Each station, station group and outside line can have an 11 character directory
name. This name will appear on keyset displays to provide additional information
about lines and stations.

TENANT SERVICE (2)

There are several programs that allow the DCS 50si to be installed in tenant appli­cations. These features allow a technician to split the system in two with each
tenant having individual control over operator groups, page zones, speed dial num­bers, night service (manual or automatic), DISA and customer level programming.
Each tenant is separate. No intercom calling between tenants is permitted.

4.1.17

TOLL RESTRICTION

There are 250 allow and 250 deny entries of 11 digits each. Each of these entries
can apply to dialing classes B, C, D , E, F and G. Expensive 976, 1-900, 411 and
operator-assisted calls, as well as specific area and office codes, can be allowed or
denied on a per-class basis. Class A stations have no dialing restrictions and Class
H stations cannot make outside calls.

Any outside line may be programmed to follow station toll restriction or follow the
toll restriction class assigned to it. Each station and trunk can have a day dialing
class and a night dialing class.

SPECIAL CODE TABLE

A Special Code Table of ten entries (four digits each) allows use of telephone
company features such as CID blocking (*67) or call waiting disable (*70) without
interference to toll restriction or LCR. The Special Code table allows use of these
custom calling features on a per call basis.

TOLL RESTRICTION OVERRIDE

Program options allow system speed dial numbers to follow or bypass a station’s
toll restriction class. In addition, users may make calls from a toll restricted station
by using the walking class of service or authorization code feature.

CONTENTS

TONE OR PULSE DIALING

Outside lines can be programmed for either tone or pulse dialing to meet local
telephone company requirements.

TRANSFER

System operation permits station users to transfer calls to other stations in the
system. Transfers can be screened, unscreened or camped-on to a busy station.

TRUNK GROUPS (11)

Outside lines can be grouped for easy access by dialing a code or pressing a
button. There are 11 trunk groups available. Access codes are 9 and 80–89.

UNIFORM CALL DISTRIBUTION (UCD)

UCD is used whenever the user expects to have more ringing calls than people to
answer them. It prevents callers from receiving busy signals or lengthy delays be­fore answering. Callers reaching a busy station group are held in queue for an
available agent. First and second announcements reassure the caller until an agent
becomes free. Up to five separate UCD groups can be created. Programmable
automatic logout removes a station from the group if a call is placed to an unat­tended station, thus preventing unanswered calls. A wrap-up timer prevents calls
to a station for a programmable period of time to allow the agent to finish up work
associated with the call.

NOTE: Requires optional hardware and/or software. Ask your dealer for details.

4.1.18

MAXIMUM OF FIVE GROUPS

The UCD group option allows callers in queue at a UCD group to be temporarily
diverted to an announcement device and then placed back in the queue. A wrap-up
timer will allow agents to complete paperwork before receiving the next UCD call.

CALL STATISTICS

UCD supervisor positions using a display keyset can monitor the number of calls in
queue, the time that the oldest caller has been waiting, the total number of calls
received for the current day and the average time a caller waits to be answered.

AGENT STATISTICS

UCD supervisor positions using a display keyset can monitor the number of agents
in a group and how many agents are currently logged in. Each station’s status can
be reviewed for the number of calls answered and the average call length of the
current day.

GROUP SUPERVISORS

Multiple supervisors can be assigned to each group or one station can be given
supervisor status for multiple groups. The group supervisor (using a display keyset)
can add and delete agents in real time from the group to handle the workload.

CONTENTS

PRINTED REPORTS

Agent supervisors may run printed reports to a customer-provided printer, showing
the data available on the supervisor displays.

UNIVERSAL ANSWER

Station users may dial the Universal Answer code or press the UA key to answer
any outside lines programmed to ring the UA device. The UA device can be a
station, group of stations, common bell or ring over page.

VOICE MAIL INTEGRATION

The DCS 50si system uses DTMF tones (inband signaling) to communicate with
any compatible voice mail system. Stations can call forward to a voice mail system.
When answered, the system will send DTMF tones routing the caller directly to the
called station user’s mailbox. Keyset users can press one button to retrieve mes­sages from the voice mail system. A Voice Mail Transfer key permits keyset users
to easily transfer a caller directly to an individual voicemail box without navigating
through menus.

NOTE: Although most voice mail systems will work with the DCS 50si, the system
data has default values set to work with the Starmail Voice Processing System.
They may need to be changed if you are using another system.

4.1.19

WALKING CLASS OF SERVICE

This feature allows users to make calls or use features from a station that is re­stricted. The users may either use the WCOS feature code or the authorization
code feature. Both methods change the class of service to correspond with the
station passcode or authorization code that is dialed. After the call is completed,
the station returns to its programmed class of service.

4.2 STATION FEATURE DESCRIPTIONS

ADD-ON MODULE

The add-on module (AOM) adds to the capability of any keyset or can be used by
itself whenever a handset and dial pad are not desired. The 32 programmable
buttons can be used for feature keys, DSS/BLF keys or one touch speed dial but­tons.

APPOINTMENT REMINDER

Keysets with an alarm key can be used like an alarm clock. When programmed for
a specific time, the keyset will sound a distinctive ring to remind the user of meet­ings or appointments. Alarms can be set for “today only” or for every day at the
same time. Up to three alarms may be set at each keyset. Display keysets can also
show a programmed message when the alarm rings.

4.2.1

AUTOMATIC HOLD

Station users can enable or disable automatic hold at their keysets. While a user is
engaged on an outside (C.O.) call, pressing another trunk key, route key or CALL
button automatically puts the call on hold when this feature is enabled. Pressing
TRSF, CONFERENCE, PAGE or a DSS key will always automatically place the call
on hold. This type of automatic hold is not a user-selectable option.

AUTOMATIC PRIVACY

All conversations on outside lines and intercom calls are automatically private. The
privacy feature can be turned off on a per-line basis.

BACKGROUND MUSIC

When customer-provided music sources are connected, each keyset user may
listen to background music. The HOLD button turns BGM on or off and the volume
is controlled by the volume control keys. Once source is located in the KSU. A
second source is located on the optional SMISC card.

BUSY STATION CALLBACK

When reaching a busy station, callers may request a callback by pressing one
button or dialing a code. The system rings the caller back when that station be­comes idle (a system-wide maximum of 100 callbacks are allowed at one time
including busy station and busy trunk).

CONTENTS

BUSY STATION INDICATIONS (BLF)

DSS/BLF keys may be assigned to any keyset or add-on module. These buttons
will be off when the station is idle, light red when that station is in use and flash
distinctively when that station is in the DND mode.

CALL FORWARDING

Station users can forward internal and outside calls to other destinations immedi­ately (Forward All), when busy (Forward Busy) or if not answered in a program­mable number of seconds (Forward No Answer). These forward destinations can
all be different. Once a destination has been programmed, it can be turned on and
off with a programmable key. Forward All takes priority over Busy and No Answer
conditions.

In addition to the three usual methods of forwarding described above, a fourth
option called Follow Me is available. This option allows a station user to set a
Forward All condition from his/her station to another station while at the remote
station. To display the Follow Me condition, the TRSF key lights steady red at the
station that is forwarded. The TRSF key also lights if Forward All is set and no key
is programmed for Forward All.

Keyset users can be given an external call forward button to forward their calls to
an external phone number. Each outside line may be programmed to either follow

4.2.2

or ignore station call forwarding. A per-station option controls whether internal calls
forward to voice mail or not. Single line telephones must have the system adminis­trator program this feature for them.

CALL PICKUP

With directed call pickup, a user can answer calls ringing at any station by dialing a
code plus that extension number. The group pickup feature allows the user to an­swer any call ringing within a pickup group. Pickup keys may be customized with
extenders to allow pickup from a specific station or pickup group. The DCS 50si
has 20 programmable pickup groups.

DIAL BY NAME

Each system and personal speed dial number can have an associated directory
name. A speed dial number can be selected by scrolling alphabetically through the
directory name list. This on-line “directory” allows the user to look up and dial num­bers in seconds.

DIRECT STATION SELECTION (DSS)

Programmable keys can be assigned as DSS keys and associated with extension
numbers. Users press these keys to call or transfer calls to the assigned stations.

DO NOT DISTURB (PROGRAMMABLE)

CONTENTS

The Do Not Disturb (DND) feature is used to stop all calls to a station. System
programming can allow or deny use of the DND feature for each station. Parties
calling a station in DND will receive reorder tone. When in DND mode, calls may be
forwarded to another destination. See Forward DND option. A keyset without a
DND button can activate DND via the feature access code. The ANS/RLS key will
flash at 112 ipm (rapidly) when DND is set. There is a programmable option to allow
a C.O. line to override DND at its ring destination if that destination is a single
station.

DOOR LOCK RELEASE

Stations programmed to receive calls from a door phone can dial a code to activate
a contact closure for control of a customer-provided electronic door lock.

EXCLUSIVE HOLD

Pressing HOLD twice will hold a call exclusively at a station so no other station can
pick up that call. Intercom calls are automatically placed on exclusive hold.

GROUP LISTENING

This feature allows users to turn on the speaker while using the handset. It allows
a group of people to listen to the distant party over the speaker without the micro­phone turned on.

HEADSET OPERATION

Every keyset can be programmed to allow the use of a headset. In the headset
mode, the hookswitch is disabled and the ANS/RLS key is used to answer and

4.2.3

release calls. Keyset users may turn headset operation ON/OFF by keyset pro­gramming or more easily by pressing the headset ON/OFF key. The headset key
lights steady red when the keyset is in headset mode. The ANS/RLS key lights if
headset mode is activated by keyset programming only.

HEARING AID COMPATIBLE

All DCS keysets are hearing aid compatible as required by Part 68 of the FCC
requirements.

LINE QUEUING WITH CALLBACK

When the desired outside line is busy, the user can press the CALLBACK key or
dial the access code to place his/her station in a queue. The user will be called
back when the line is available (a maximum of 100 callbacks are allowed system­wide at one time including busy station and busy trunk).

LINE SKIPPING

When the user is talking on an outside line and the automatic hold feature is turned
off, he/she may press an idle line key and skip to that line without causing the
previous call to go on hold.

MESSAGE WAITING LIGHT/INDICATION

When a message indication is left at a keyset, the MESSAGE button will slowly
flash red. Single line telephones will receive a distinctive dial tone to notify them
that a message is waiting. Message waiting indications can be left for any station or
group of stations.

CONTENTS

MUTE MICROPHONE/HANDSET

Any keyset user can mute the keyset’s handset transmitter by pressing the MUTE
key. In addition, keyset users can also mute the keyset microphone while the keyset
is in speakerphone mode.

OFF-HOOK RINGING

When a keyset is in use, the system will provide an off-hook ring signal to indicate
that another call is waiting. The ring signal is a single ring repeated. The interval is
controlled by a system-wide timer. Single line stations will receive a tone burst
through the handset receiver instead of a ring.

OFF-HOOK VOICE ANNOUNCE (STANDARD)

Keysets may receive a voice announcement while on another call. The calling sta­tion must have an OHVA key. When transferring a call to a busy keyset or while
listening to busy signal, the station user can press the OHVA key to make an OHVA
call to the busy keyset. If the called keyset is in the DND mode, it cannot receive
OHVA calls.

4.2.4

OFF-HOOK VOICE ANNOUNCE (EXECUTIVE)

A keyset associated with an add-on module (AOM) may receive an executive off­hook voice announcement while on another call. The called keyset user may reply
handsfree without interrupting the call in progress. Only keysets with an off-hook
voice announce button (OHVA) can off-hook voice announce to keysets with AOMs.

ONE TIME DO NOT DISTURB

The Do Not Disturb (One Time) feature is used to stop all calls to a station when the
user is on an outside line and does not want to be disturbed for the duration of the
call. Upon completion of the call, DND is canceled and the station is returned to
normal service. This feature requires a programmed button.

ONE TOUCH DIALING KEYS

Frequently used speed numbers can be assigned to one touch dialing keys for fast
accurate dialing.

ON-HOOK DIALING

Any keyset user can originate calls without lifting the handset. When the called party
answers, the user may speak into the microphone or lift the handset for more privacy.

PROGRAMMABLE KEYS

CONTENTS

LCD 24B and STD 24B keysets have 24 programmable keys and LCD 12B and
Basic 12B keysets have 12. Each key can be programmed for more than 25 differ­ent uses to personalize each phone. Examples of keys include individual outside
line, individual station, group of lines, group of stations and one touch speed dial
buttons. Using these keys eliminates dialing access codes.

The following feature keys have extenders that make them more specific: SPEED
DIAL, SUPERVISOR, PAGE, DSS, DIRECTED PICKUP, GROUP PICKUP, DOOR
PHONE, BOSS, PROGRAMMED MESSAGE, IN AND OUT OF GROUP, FOR­WARD and VOICE MAIL TRANSFER. The extender can be a station, a group or
another identifying number.

PROGRAMMED STATION MESSAGES

Any station may select one of twenty messages to be displayed at a calling party’s
keyset. Ten messages are factory-programmed and the remaining ten can be cus­tomized by the system administrator (16 characters maximum).

NOTE: The calling party must have a display keyset to view these messages.

PROTECTION FROM BARGE-IN

Each station can be programmed as secure or not secure. Secure stations cannot
be barged-in on. A station that is not secure cannot be barged-in on when talking to
a secure station.

4.2.5

PULLOUT DIRECTORY TRAY

A pullout directory tray is conveniently located beneath all keysets. It is used to
record station directory names and speed dial numbers.

PULSE TO TONE SWITCHOVER

When dialing a number on a dial pulse network, a station user can dial # and the
DCS system will begin to send DTMF.

REDIAL

There are three types of external redial available to all station users. Each type can
redial up to a maximum of 18 digits.

l AUTO RETRY—When an outside number is dialed and a busy signal is received,

the auto retry feature can be used to reserve the outside line and automatically
redial the number for a programmable number of attempts.

l LAST NUMBER—The most recently dialed number on a C.O. line is saved and

may be redialed by pressing the redial key or dialing the LNR access code.

l SAVE NUMBER—Any number dialed on a C.O. line may be saved for redial at

a later time.

CONTENTS

REMOTE HOLD

When you wish to place a call on hold at another station, press TRSF and dial the
station number (or press the appropriate DSS key). Press the HOLD key. This will
place the call on system hold on an available CALL button or Line Key at the
remote station.

RING MODES

Each keyset user can select one of three distinct ways to receive intercom calls.
The phone can automatically answer on the speakerphone, voice announce through
the speaker or receive ringing. When the ring mode is selected, keyset users can
choose one of eight distinct ring tones. Forced Auto Answer is invoked by the
calling station and is controlled by the calling station’s class of service.

RINGING PREFERENCE

Lifting the handset or pressing the speaker button automatically answers a call
ringing at the keyset. Using this method, users are assured of answering the oldest
call first. When ringing preference is turned off, the user must press the flashing
button to answer. Users may answer ringing lines in any order by pressing the
flashing button.

SPEAKERPHONE

LCD 24B, STD 24B, LCD 12B and Basic 12B keysets have a built-in speakerphone.
The speakerphone enables calls to be made and received without the use of the
handset.

4.2.6

STATION LOCK

With a programmable personal station passcode, any keyset can be locked and
unlocked. A locked keyset cannot be used to make or receive calls.

TRI-COLORED LIGHTS

LCD 24B and STD 24B keysets have 16 keys equipped for tri-colored LED indica­tions (green, red and amber). LCD 12B and Basic 12B models have six of these
keys. To avoid confusion, your calls always light green, other calls show red and
recalls light amber.

VOLUME SETTINGS

Each keyset user may separately adjust the volume of the ringer, speaker, handset
receiver, background music, page announcement and off-hook ring tone.

WALL-MOUNTABLE KEYSETS

Each keyset, add on module and 64 button module can be wall mounted by revers­ing the base wedge. The newest base wedge may not fit all wall mounting sce­narios so in these cases the original wall mount/base wedge unit should be used.

ACCOUNT CODE DISPLAY

Account codes are conveniently displayed for easy confirmation. If entered incor­rectly, users may press the ACCOUNT key again and reenter the account code.

CALL DURATION TIMER

The system can automatically time outside calls and show the duration in minutes and
seconds. Station users may manually time calls by pressing the TIMER button.

CONTENTS

CALL FOR GROUP IDENTIFICATION

When a call is made to a station group, the display shows [CALL FOR GROUP]
and the user’s group number. These calls can be answered with a different greet­ing than calls to the user’s extension number.

CALL PROCESSING INFORMATION

During everyday call handling, the keyset display will provide information that is
helpful and in some cases invaluable. Displays such as [CALL FROM 203], [TRANS­FER TO 202], [701: RINGING], [TRANSFER FM 203], [708 busy], [Camp on to
204], [Recall from 204], [Call for 501], [message from 204] and [FWD ALL to 204]
keep users informed of what is happening and where they are. In some conditions,
the user is prompted to take action and in other cases the user receives directory
information.

CALLER ID INFORMATION

Caller ID information is dependent on the use of display keysets. The following list
explains the displays that are used with Caller ID.

NAME/NUMBER DISPLAY

Each display keyset user can decide if he/she wants to see the Caller ID name or
Caller ID number in the display. Regardless of which one is selected to be seen
first, the N/N key is pressed to view the other piece of CID information.

4.3.1

NEXT CALL

In the event that there is a call waiting or a camped-on call at the user’s keyset, the
user can press the NEXT key to display the Caller ID information associated with
the next call in queue at the station. Either the CID name or CID number will show
in the display depending on the N/N selection.

SAVE CID NUMBER

At any time during an incoming call that provides CID information, the user may
press the SAVE key. This saves the CID number in the Save Number feature.
Pressing the SAVE number redial key will dial the CID number. The system must
be using LCR to dial the saved number.

STORE CID NUMBER

At any time during an incoming call that provides CID information, the user may
press the STORE key. This saves the CID number as a speed dial number in the
personal speed dial list. The system must be using LCR to dial the stored number.

INQUIRE PARK/HOLD

When a user is informed that an incoming call is on hold or has been parked, the
user may view the Caller ID information before he/she retrieves the call. This will
influence how the user chooses to handle the call.

CONTENTS

CID REVIEW LIST

This feature allows display keyset users to review CID information for calls sent to
their stations. This list can be from ten to fifty calls in a first in, first out basis. The list
includes calls that were answered and calls that rang the user’s station but that
were not answered. When reviewing this list, the user can press one button to dial
the person back. The system must be using LCR to dial the stored number.

INVESTIGATE

This feature allows selected stations with a special class of service to investigate
any call in progress. If CID information is available for an incoming call, the se­lected stations can know to whom the investigated user is speaking. On outgoing
calls, the selected stations can see who was called. After investigating, the se­lected stations may barge-in on the conversation, disconnect the call or hang up.

ABANDON CALL LIST (50)

The DCS 50si has a system-wide abandon call list that stores CID information for
the last 50 calls that rang but were not answered. The list is accessed using the
operator’s passcode. When reviewing this list, the user is provided options to CLEAR
the entry or DIAL the number. The user can use the NND key to toggle between the
CID name, CID number and the date and time the call came in. The system must
be using LCR to dial numbers from the abandon call list.

4.3.2

CALLING PARTY NAME

For intercom calls, LCD 24B and LCD 12B keysets show the calling party’s name
before answering. The names must be stored in the system directory list and can
be up to 11 characters long.

CALLING PARTY NUMBER

When an intercom call is received, all display stations show the calling party’s ex­tension number before the call is answered.

CONFERENCE INFORMATION

When a conference is set up, each extension and outside line number is displayed
at the controlling station when it is added. When a station is added, its display
shows [Conf with xxx] alerting the user that other parties are on the line.

DATE AND TIME DISPLAY

In the idle condition, the current date and time are conveniently displayed. Display
keysets can have a 12 or 24 hour clock in either the ORIENTAL or WESTERN
display format with information shown in upper case or lower case letters.

DIALED NUMBER

CONTENTS

When an outside call is made, digits are displayed as the user dials them. If the
display indicates an incorrect number was dialed, the user can quickly hang up
before billing begins.

ENHANCED STATION PROGRAMMING

Personal programming options are easier to select and confirm with the help of the
display.

IDENTIFICATION OF RECALLS

Hold recalls and transfer recalls are identified differently than other ringing calls.
Hold recalls indicate the recalling line or station number and the associated name.
Transfer recalls indicate the recalling line or station and where it is coming from.

IDENTIFICATION OF TRANSFERS

The display will identify who transferred a call to the user.

MESSAGE WAITING CALLER NUMBER

When the message indication is on, pressing the MESSAGE button displays the
station number(s) of the person(s) who have messages for the user. Display keyset
users can scroll up and down to view message indications.

OUTSIDE LINE IDENTIFICATION

Each line can be identified with an 11 character name. Incoming calls display this
name before the call is answered. This feature is helpful when individual lines must
be answered with different greetings.

4.3.3

OVERRIDE IDENTIFICATION

If another station barges-in on a user’s conversation, the display will alert the user
with a [Barge from 2xx] display if the system is set for barge-in with tone.

PROGRAMMED MESSAGE DISPLAY

Preprogrammed station messages set by other stations are displayed at the calling
station’s keyset.

SOFT KEYS

Below the display, there are three soft keys and a SCROLL button. These keys
allow the user to access features in his/her class of service without requiring the
keyset to have designated feature keys.

STOPWATCH TIMER

Display keyset users find this feature very convenient to time meetings, calls and
other functions. Users simply press once to start the timer and press again to stop
the timer.

UCD SUPERVISOR DISPLAYS

With the optional SMISC2 card, when UCD is used, multiple supervisors can view
information about the UCD groups calls or agents.

CONTENTS

CALL SCREEN
This allows the supervisor to view how many calls are in queue, the longest wait

time, how many calls have been received today, what the average time in queue is
and how many calls were abandoned.

AGENT SCREEN
This allows the supervisor to monitor how many agents are logged in, check each

agents status (IN GROUP, OUT OF GROUP, or DND), view each agents total num­ber of calls, average call length or average ring time.

NOTE: Accessing this screen will also allow a Supervisor to change the status of
each agent (IN GROUP, OUT OF GROUP, or DND).

4.7 CALL STATISTICS

CALLS IN QUEUE NOW

How many calls are currently in queue.
This statistic is a real time statistic and so will not print on a report.

ABANDONED CALLS

This shows the number of callers that reached the UCD group, but hung up before
being answered. A high number probably means that there are not enough agents
available and the wait time is too long.

AVERAGE RING TIME

This is calculated from the time an agent begins to ring until the time an agent
answers the call, this does not include ringing at an agent station that does not
answer or is logged out because of the ring next option.

NUMBER OF TIMES ALL AGENTS BUSY

This is the number of times that a call is placed to an UCD group and all agents are
busy or out of group. This check is made when the call is first placed to the group.

CONTENTS

Example: If there are 5 members in a group, 3 are Out of Group one is busy and
one is idle, and a call is placed to the group, because there is an idle station the all
agents busy counter is not incremented.

If the idle station rings, does not answer and is logged out, although the condition of
the group is now all agents busy, the check has been made and the agent busy
statistic does not increment.

Also if a call comes into a group with all agents busy and then one becomes idle,
the busy counter will increment because the check has been made.

AVERAGE TIME IN QUEUE

This is calculated as an average of all the calls that were in queue.
Note that this is ONLY an average of the calls that were in queue. The caller must

have overflowed to the UCD recording to be considered in queue.
A call is considered in queue until it is answered or until it goes to the final destina-

tion.

TOTAL CALLS RECEIVED

The total number of times that calls were sent to a group. This includes calls that
were answered by the group, calls that went to a group with all agents busy or out
of group, calls that are abandoned and calls that go to UCD final destination. This
includes intercom calls to the UCD group.

4.7.1

If this number is less than the total calls received by all the agents it is possible that
calls were transferred from one agent to another.

If this number is more than the total calls received by all the agents it is possible
that calls were unanswered by an agent and went to final destination or callers
hung up while in queue.

This statistic includes:
a) Calls answered by agent.

b) Calls that are not answered by an agent and go to final destination.
c) Calls that are sent to the UCD group but callers hang up before being answered.

LONGEST QUEUE TIME TODAY

This shows the longest call in queue today. The queue time is calculated as fol­lows:

a) Queue time begins when a caller starts to hear the first UCD message.
b) Queue time ends when a caller is either

• Answered by an agent

• System gets disconnected from C.O. or

• Caller is transferred to final destination

CONTENTS

LONGEST QUEUE TIME NOW

be In Group, Out of group or in DND.

This statistic is a real time statistic and so will not print on a report.

CALLS ANSWERED

The total number of calls answered by the agent. This does not include ring no
answer to an agent station.

If this total number is less than the calls received by the group it is possible that
calls were unanswered by an agent and went to final destination or that callers
hung up while in queue.

If this total number is more than the calls received by the group it is possible that
calls were transferred from one agent to another.

not exceed 5.0. To be certain of the number of devices that may be connected to the line,
as determined by the number of RENs, contact the telephone company to determine the
maximum REN for the calling area.
