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 400si provides an interface for connecting a customer-provided external mu-
sic source. Additional two sources can be provided with additional hardware.  These
sources can be used for background music, station music on hold, trunk music on
hold and transfer music on hold.
EXTERNAL PAGE INTERFACES
The DCS 400si common control card (DCCP) provides one external page output
and two zone control relays. Resources from an added miscellaneous applications
card (DMAP1) can be combined to provide two external zones. Multiple relays may
be assigned to each 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 conjunc-
tion 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. Three digit default extension numbers begin
with 201 and four digit defaults begin with 2001. Station group numbers can be
three or four digits beginning with the digit 5.
Using digits other than 2, 3 or 5 will require the technician to change other feature
access codes in the system default numbering plan. User guides will need to be
modified as  these are all written using the 400si default numbering plan.
GROUND START TRUNKS (T1/COPPER)
The 400si can utilize these trunks to support a positive disconnect signal and pre-
vent call collisions on heavy traffic usage. Caller ID or ANI service is not available
on these trunks.
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.
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.
ISDN SERVICE
PRIMARY RATE INTERFACE (PRI)
The DCS 400si supports Primary Rate Interface ISDN. PRI allows simultaneous
data calls, calling party and calling line identification , high speed call setup and
disconnect are among the benefits if ISDN calling.  The 23B+D configuration of
ISDN allows call information to be delivered via the data channel (the “D” of 23B+D)
thus leaving the bearer channels (the “B” of 23B+D) available for single use or
combined use to provide a wider bandwidth for data and video.  The 400si supports
the most popular protocol standards in the U.S.
PRI Protocols supported:National ISDN-2 (NI2),
AT&T No. 5 ESS Custom
DMS 100/250
BASIC RATE INTERFACE (BRI)
The DCS 400si BRI card supports trunk or station level Basic Rate Interface ser-
vices (BRI). Trunk or station BRI use is software programmable. BRI allows simul-
taneous data calls, called party and calling number identification, high speed call
setup and disconnect are among the benefits if ISDN calling.  The 2B+D configura-
tion of ISDN allows call information to be delivered via the data channel (the “D” of
2B+D) thus leaving the bearer channels (the “B” of 2B+D) available for single use
or combined use to provide a wider bandwidth for data and video.

4.1.15
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
400si LCR program includes the following features:
•Option to use or not use LCR on a tenant basis
•Programmable LCR access code
•Digit analysis table 3000 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 500 entries
•Flexible trunk group advance timer
•Option to use or not use trunk group advance warning tones
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 lithium battery for approximately one year. In addition,
the PCMMC computer program may be used to produce a backup copy of the
customer data. Additionally, an optional DCDM daughterboard may be used to
store the system database.
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 can receive a distinctive
message waiting dial tone or a message lamp indication. 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. 
						

							CONTENTS
4.1.16
MUSIC ON HOLD—FLEXIBLE
With external music on hold sources connected, each C.O. line may be programmed
to receive one of the external sources, internally-generated tones, chime music or
no music when it is placed on hold. If there are no external sources installed, each
line may receive either a system-generated tone or no music. The system-gener-
ated tone is a beep every ten seconds. The DCCP card provides an internally
chimed music source playing Green Sleeves and the DMAPI internally chimed
source playing Home on the Range.
OFF PREMISES EXTENSIONS (OPX)
A single line (tip and ring) extension from an 16SLI card may be connected to
telephone company-provided OPX circuits to remote locations. D24SL 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. There can
be only one (1) operator group per tenant.
OVERFLOW
OPERATOR
When calls ringing to the 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.
PARK ORBITS
The system has 10 park orbits (0–9). These orbits can be used to park calls prior to
paging and allows the call to be retrieved by dialing a park code plus the orbit
number. Calls parked in this manner can also be retrieved by dialing the park pickup
code (10) plus the station or trunk number. This feature is in addition to Call Park
and Page.

4.1.17
POWER FAILURE TRANSFER
The DCS 400si cabinet can be equipped with the 16 circuit power fail relay transfer
unit (DPFT). If power fails, these relays can be used to reroute the 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 automatically select a specific line, trunk group,
telephone number, station or station group when the handset is lifted or the speaker
key is pressed (same as Hot Line feature).
PRIVATE LINES
For private line use, stations can be prevented from dialing and/or answering any
line.
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 MODES
TIME BASED ROUTING – PLANS
Each C.O. line can be programmed to ring at any station or station group. Each line
can be assigned a ring destination based on six (6) different ring plans based on
time of day and the day of the week. 
						

							CONTENTS
4.1.18
AUTOMATIC / MANUAL
Ring destinations will automatically change based on time of day and day of week.
At any time the system can be manually forced into a specific ring plan. It will
remain in this ring plan until manually taken out.
HOLIDAY SCHEDULE
The system has a table of 20 dates that are used to define holidays. On a date
designed as a holiday the system will remain in a ring plan for that calendar day
providing the system was already in night service. This feature will override the ring
plan time table.
TEMPORARY OVERRIDE
At any time the system can be forced into a specific ring plan for a temporary period
of time until the next scheduled rin plan automatically takes effect.
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 400si intercom ring
cadence.
SPEED DIAL NUMBERS (2500)
A library of 2500 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 24 digits.
SPEED DIAL BY DIRECTORY
The 400si 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 and
station. This feature requires a display keyset.
STATION HUNT GROUPS (50)
System programming allows up to 50 station hunt groups. One of three ring pat-
terns—sequential, distributed and unconditional—is available for each group. Each
unconditional group may contain a maximum of 32 stations and each sequential
and distributed group may contain a maximum of 48 stations. A station may be

4.1.19
assigned to more than one group. The default directory numbers to call these groups
are 501–549 and default four digit directory numbers are 5001–5049  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.
STATION PAIR
This feature allows station to be assigned as a “pair”. That is to say a primary and
secondary. Calling the primary station will make both stations ring. Selected fea-
tures such as Message Notification, DND, Callback, and Class of Service act as
one station. This is convenient when an individual has two offices or an office ex-
tension and a cordless extension.
NOTE: Not all system features are applicable to station pairs. Features designed
for a single user may conflict with paired stations.
STATION TO STATION RESTRICTION
This feature restricts any station from calling any other station. It is useful when two
or more companies share the same 400si system but want one operator and maybe
one boss/owner. Not the same as Tenant Service.
SYSTEM ALARMS
The 400si provides two special alarms, SYSTEM and DISA.
The common control card (DCCP) has an alarm sensor pair. When this pair is
short-circuited, the system will ring a preprogrammed destination with a custom-
ized  SYSTEM alarm message (16 characters maximum). The alarm destination
can be any 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 station or
station group and show an appropriate display (16 characters maximum) at the
assigned stations.

4.1.20
SYSTEM MAINTENANCE ALARMS
The 400si continuosly performs internal system diagnostics. When either \
a major 
or minor fault is detected the system can ring stations with an ALARM KE\
Y as-
signed. The keyset display shows information that includes the descripti\
on, loca-
tion and date and time stamp for each alarm. 
A log of 100 alarms are stored in a buffer and can be reviewed at a display keyset 
or sent to a printer (see sample Alarm Report in section 4. 11 of this document ). In
addition to the keyset displays LEDs, the front of the DCCU card will li\
ght to indi-
cate a major or minor alarm.
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 400si to be installed in t\
enant
applications. These features allow a technician to split the system in t\
wo with each
tenant having individual control over operator groups, page zones, ring \
modes
(manual or automatic), DISA and customer level programming. Each tenan\
t is sepa-
rate. No intercom calling between tenants is permitted.
TOLL RESTRICTION
There are 500 allow and 500 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 restrictio\
ns 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 u\
se 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 st\
ation ’s
toll restriction class. In addition, users may make calls from a toll re\
stricted station
by using the walking class of service or authorization code feature.

4.1.21
TONE OR PULSE DIALING
Outside lines can be programmed for either tone or pulse dialing to meet local
telephone company requirements.
TRAFFIC REPORTING
The DCS 400si system can store peg counts for various types of calls. These peg
counts can be printed on-demand, daily at 23:59 p.m., or weekly on Saturday at
23:59 p.m. The report includes statistics for each trunk, trunk group, station, station
groups and page announcements. 
For more details and explanations see sections
4.9 and 4.10 of this document.
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 (49)
Outside lines can be grouped for easy access by dialing a code or pressing a
button. There are 49 trunk groups available. Default access codes are 9 and 801–
848.
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 be-
fore 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 twenty separate UCD groups can be created. Programmable
automatic logout removes a station from the group if a call is placed to an unat-
tended 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. Ask your dealer for details.
MAXIMUM OF TWENTY (20) 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. 
						

							CONTENTS
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.
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 400si 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 mes-
sages from the voice mail system. A Voice Mail Transfer key permits keyset users
to easily transfer a caller directly to an individual voice mailbox without navigating
through menus.
NOTE: Although most voice mail systems will work with the DCS 400si, 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.
WALKING CLASS OF SERVICE
This feature allows users to make calls or use features from a station that is re-
stricted. 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.
