Samsung Dcs 50si General Description Manual

							

4.1.8
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 Program-
ming 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 com-
puter. TSAPI is a LAN based solution allowing computers to communicate directly
to the telephone system over the network system. This establishes a logical con-
nection rather than a physical connection between telephone and computer. It elimi-
nates 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 tele-
phone 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 commu-
nications link between the Novell Netware file server running the Netware Tele-
phony 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.
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. 
						

							

4.1.9
DATA SECURITY
Single line extensions used with modems and facsimile machines can be pr\
o- 
grammed so that they will not receive any system-generated tones that wo\
uld dis-
rupt data transmissions. In addition, these devices receive DCS C.O. rin\
ging pat-
tern 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 inf\
orma-
tion can be directed to a printer or the PC screen and may be done eithe\
r 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 dir\
ectly at
any station or group of stations.
DIRECT INWARD DIALING (DID-USE E&M TRUNK)
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, th\
e 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 ring\
ing 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 id\
entified 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 ty\
pe service.
DIRECT INWARD SYSTEM ACCESS (DISA)
Users can call in on specific DISA lines at any time, input a security c\
ode and
receive system dial tone. Users can now place internal calls or if permi\
tted, calls
using C.O. lines. The caller must have a tone dial phone and know his/he\
r 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 t\
runk group
by access code when LCR is activated. When restricted, the station user \
must use
a trunk key or a route key. 
						

							

4.1.10
DIRECTORY NAMES
Each station, station group and C.O. line may be assigned a directory name (maxi-
mum 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 (maxi-
mum 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 re-
peatedly (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)
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 an-
swered 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 
						

							

4.1.11
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 barge-
in 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 micro-
phone muted and the barged-in on station does not receive an override display.
This feature does not work from single line sets.
WARNING: BARGE-IN WITHOUT TONE MAY VIOLATE STATE OR FEDERAL
LAWS CONCERNING THE RIGHT TO PRIVACY. SAMSUNG TELECOMMUNI-
CATIONS AMERICA IS IN NO WAY RESPONSIBLE FOR THE POSSIBLE MIS-
USE OF THIS FEATURE.
EXECUTIVE/SECRETARY POOLING
Each keyset may be defined as a BOSS or a SECRETARY in system program-
ming. Each BOSS can have up to four SECRETARIES and each SECRETARY
can have up to four BOSSES. These arrangements are known as executive/secre-
tary 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 SEC-
RETARY 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. 
						

							

4.1.12
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 num-
bers 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
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 when-
ever 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 tele-
phones 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. 
						

							

4.1.13
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 chan-
nels.
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:

National ISDN 2

AT&T 5ESS Custom

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: Install-
ing 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 effec-
tive central office route for the outside number dialed by any station. The DCS 50si
LCR program includes the following features:

Option to use or not use LCR or a tenant basis

Programmable LCR access code

Digit analysis table 1000 entries each with ten digits

Routing by time of day and day of week (4 time bands per day)

Routing according to individual station class

Modify digits table 100 entries

Flexible trunk group advance timer

Option to use or not use trunk group advance warning tones 
						

							

4.1.14
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 program-
ming: technician, customer and station. The technician level has access to all pro-
grams and can allow the customer access to system programs as needed. Techni-
cian and customer access are controlled by different security passcodes. Program-
ming 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 addi-
tion, 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.
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 lis-
tening 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. 
						

							

4.1.15
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 tele-
phone company-provided OPX circuits to remote locations. 8SLI cards and KDb-
SLIs 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.
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. 
						

							

4.1.16
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 originat-
ing station if not answered within a programmable time. A recall that goes unan-
swered for the duration of the attendant recall timer will recall to the system opera-
tor group. Hold, transfer, camp-on and attendant recalls have individual program-
mable 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. Cus-
tomer-provided modems and a PC using an optional software package will be needed
to implement this feature.
RING OVER PAGE
Any outside line can be programmed to ring over a customer-provided paging sys-
tem. 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 fac-
simile 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 en-
sure correct operation. Central office ring cadence can be selected for SLT sta-
tions. This is helpful when optional devices cannot detect DCS intercom ring ca-
dence.
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 
						

							

4.1.17
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 rin\
g pat-
terns—sequential, distributed and unconditional —is available for each group. Each
unconditional group may contain a maximum of 32 stations. A station may \
be as-
signed to more than one group. The default directory numbers to call the\
se groups
are 501 –529. Group 500 is reserved for the operator group and is called by diali\
ng
“ 0. ” Each station group has its own recall timer for calls transferred to th\
at group.
STATION MESSAGE DETAIL RECORDING (SMDR)
The system provides, via an optional SIM, records of calls made, receive\
d and
transferred. Connecting a customer-provided printer or call accounting s\
ystem will
allow collection of these records. Each call record provides the followi\
ng 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 pri\
nt a
header followed by 50 call records per page or send continuous records w\
ith 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 ca\
lls,
in and out of group status, change in DND status and authorization codes\
.
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 m\
essage.
The alarm destination can be a station or station group. 
A DISA alarm will warn the customer if the DISA security system has been\
 trig- 
gered by too many incorrect password attempts. The alarm can ring any st\
ation or
group of stations and show an appropriate display at the assigned statio\
ns.
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 inf\
ormation
about lines and stations.
TENANT SERVICE (2)
There are several programs that allow the DCS 50si to be installed in te\
nant appli-
cations. These features allow a technician to split the system in two wi\
th each
tenant having individual control over operator groups, page zones, speed\
 dial num-
bers, night service (manual or automatic), DISA and customer level pro\
gramming.
Each tenant is separate. No intercom calling between tenants is permitte\
d.
