Softphone

The OfficeServ 7400 can be rack-mounted in a standard 19” data rack or set on a desktop. Its compact cabinet
design, RJ-45 connectors, and CAT 5 cabling allows it to easily integrate into any data center environment along
with existing data equipment. Expanding the OfficeServ 7400 system is both economical and easy. Begin with a
single cabinet providing 10 universal card slots, then add up to two additional cabinets as your business grows.
Its low and high density card design allows greater flexibility when configuring a system for the right combina-
tion of lines and stations. A removable software cartridge (SmartMedia card) makes it convenient to upgrade to
future feature packages.
The OfficeServ 7400 offers a variety of interface cards that allow connection to the public telephone network or
to private networks using either analog or digital circuits. Proprietary digital phones called “keysets”connect to
Digital Line Interface cards (DLI). In addition to these conventional digital keyset, Samsung offers a complete line-
up of IP terminals. These IP terminals use the latest Voice over Internet Protocol (VoIP) technology and can be
deployed over LANs or WANs. They are ideal for distant (remote) locations providing all the benefits of the
OfficeServ 7400 to home workers and road worriers. Standard telephones generally called “single line sets” con-
nect 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 exter-
nal paging, music on hold, background music, and common audible devices.
All digital and IP telephones utilize a single PCB with surface-mounted components assuring the highest prod-
uct 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.
The OfficeServ 7400 includes all of this, PLUS the same, robust, time proven, market tested feature package
offered on the OfficeServ 7200 and 500 products.
BENEFITS
• End to End Samsung components, Samsung Support and Samsung Training. The Ultimate in single source
Shopping and maintenance!
• Hardware migration from the 7200 to the 7400.

1.2 SIZE AND CONFIGURATION
The OfficeServ 7400 is a modular and flexible platform from one to three cabinets. See figures 1-2 , 1-3 and 1-4.
The first or Main Cabinet has two dedicated processor slots
for the MP40 ( Main Processor) and the LP40 (local processor)
and 10 universal slots. Each of the card slots provide 64 com-
munication channels to support high density modules. See
figure 1-5
The second and third cabinets (expansion cabinets) require
only the LP40 so they provide 11 universal slots each. Each
of the expansion cabinet card slots provide 32 communica-
tion channels.The combines total of universal slots for a fully
expanded OfficeServ 7400 is 32, ( 10 + 11 + 11). . See figure

OfficeServ 7400 Capacities
When configuring a system to meet your requirements, select the appropriate number of interface cards listed in
Part 2 of this book to support the various types of routers, switches, trunks, stations, voice mail and miscellaneous
functions. Combine both the physical ports of cabinets 1, 2 & 3 with the virtual ports in virtual cabinets 4 & 5 (see
figure 1.6) to build a system as required. Your authorized Samsung Installation and Service Company has special
knowledge and training to do this.
The following table indicates the maximum number of each circuit type or device available in the OfficeServ
7400. The system architecture is designed to be extremely flexible so as to provide a myriad of configurations.
However it is impossible to accommodate all the maximum numbers into one system.
Figure 1.6 indicates the physical and virtual cabinets available in the OfficeServ 7400. Physical card slots in cabi-
nets 1, 2 and 3 support the various combinations of cards detailed in Part 2. HARDWARE DESCRIPTIONS. Virtual
cabinets 4 and 5 provide twelve (12) slots each with each slot providing 32 ports (communication channels). The
total virtual devices allowed is 768.

1.3 TECHNOLOGY
MEMORY
The system operates using stored program control.This program is stored on a 32MB SmartMedia card inserted
into the Main Processor card (MP40).The Smart Media card also provides space for a backup customer database.
The customer database is stored indefinitely in NAND Flash. 2MB of SRAM backed up by a super capacitor stores
information such as Call Logs, Alarms, UCD call statistics, program logs and traffic reports up to 12 hours without
main system power.
MICROPROCESSORS
OfficeServ 7400 uses distributed processing. Its primary processor is a 32 bit Motorola MPC8271 operating at a
clock speed of 266 MHz on the MP40 card. This provides all the main processing necessary for a the system. In a
multi cabinet system the secondary level of processing is on the LP40 card for the expansion cabinet.The tertiary
level of processing is done in the keysets. The digital keysets use a Hitachi H8 processor for data communication
within the system.
1.4 PROGRAMMING
The OfficeServ 7400 is a self-configuring system. This means that immediately after applying power, the
OfficeServ 7400 reads the types and locations of all installed interface cards and keysets and assigns default data
to them. This data provides for system operation within a few minutes after applying power. All trunks and sta-
tions are assigned three or four digit numbers according to the settings of the switches on the MP40 card and the
default numbering plan.This numbering plan is flexible and may be changed to suit customer requirements.The
installing technician customizes this default data to meet the end user’s requirements.
The system can be programmed from any IP or digital two line display keyset without interrupting system oper-
ation.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
levels are controlled by a different security pass codes and access procedure.
The OfficeServ 7400 also provides a proprietary Web based program called WebMMC. It allows programming
from any where in the world provided there is network access to the MP40. WebMMC runs on a Web Server and
uses Internet Explorer V6.0 as its interface.This permits a technician to program the system using a personal com-
puter.Use WebMMC 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 be uploaded when required to restore the database.Through
the use of LAN or WAN connection, an PC can access the OfficeServ 7400 system remotely (off-site) to make data-
base changes or perform uploads or downloads of the customer database as if the technician were on-site.
1.5 MIGRATION FROM OFFICESERV 7200
For businesses using the OfficeServ 7200, Samsung provides a convenient, easy and affordable migration path to
the larger OfficeServ 7400. Simply install a 7400 as the main cabinet. Replace the MCP card of the 7200 systems
with an LP40 card and your existing 7200 cabinets and interface cards become part of a much larger OfficeServ
7400 system. Features and operation are the same so there is no need to retrain users. See the OfficeServ 7200
General Description for more details.
See figure 1.9, 1-10, and 1-11 for possible hardware combinations.

PART 2. HARDWARE DESCRIPTIONS
2.1 SYSTEM CABINETS
The OfficeServ 7400 system has a common universal cabinet design. This cabinet can be configured as the main
cabinet or as an expansion cabinet. Inserting both the MP40 & LP40 cards in specific slots makes it the main cab-
inet. Inserting the LP40 card in a dedicated slot make it an expansion cabinet. The system can be a single cabi-
net or expand to a 3-cabinet system by adding up to 2 additional expansion cabinets. The main cabinet offers 10
universal slots and each expansion 7400 cabinet offers 11 universal slots. Therefore, a 3-cabinet system offers a
total of 32 universal slots. In the main cabinet, all slots are 64-channel slots while the slots in the 7400 expansion
cabinets are 32-channel slots. The OfficeServ 7200 cabinet can also be used as an expansion cabinet. It offers 1
32-channel slot and four 16-channel slots.
2.2 PROCESSOR CARDS
MP40 (MAIN CONTROL PROCESSOR)
This is the main processor controlling system operation. The MP40 always goes in slot 3 of the main cabinet. The
MP40 provides the LP40 link connectors to connect two expansion cabinets, a LAN port, and a smart media card
slot which can accommodate a 32 MB SmartMedia card containing the system software.
The MP40 also has a connector for mounting the optional modem daughter board. This modem board can be
used for remote access to system administration at installations that do not have a LAN or WAN connection. In
addition it may be used as a backup for LAN connectivity. This is the same modem board used with the OfficeServ
500.
LP40 (LOCAL CONTROL PROCESSOR)
The LP40 is a local processor that is required in every cabinet. It must go into slot 0 of each cabinet. Even if you
have a single cabinet system, you must install an LP40. Each LP40 provides 6 five-party conference circuits and 8
DTMF receivers. All system daughter boards are installed on LP40 cards except for the modem daughter board.
2.2.1 LP40 CARD-DAUGHTER BOARDS
There following types of optional daughter boards are available to increase system resources in various combina-
tions as required. They can only be mounted on the LP40 cards (see Figure 2-1).
COMMON RESOURCE MODULE (CRM)
This multi-functional board provides various common resources that are shared through the system cabinets.The
CRM provides the following:
• Six (6) 5 party conference circuits.
• Two(2) 8 channel DSPs. Each DSP can be programmed to function as either analog Caller ID receiver/trans-
mitter or as a DTMF receiver. Choices are:
1. Eight (8) CID Receive/Transmitter plus 8 DTMF Receivers
2. Sixteen (16) CID Receivers/Transmitters
3. Sixteen (16) DTMF Receivers
2.1

SWITCH CONFERENCE MODULE (SCM)
This daughter board can only be installed in LOC1 and LOC2 of any LP40 card. It provides the following:
• Twelve (12) 5 party conference circuits.

This is the same SCM used on the OfficeServ 500 and 7200 systems.
MULTI-FREQUENCY MODULE (MFM)
The MFM Module can only be installed in LOC1 and LOC2 of any LP40 card. The purpose of the MFM daughter
board is to provide DSPs for DTMF and tone detection (busy tone, ringback, etc.) This is the same MFM daughter
board used on the OfficeServ 500 and OfficeServ 7200 systems.
• Twelve (12) DSPs for DTMF and tone detection.
R2/CID-Tx MODULE (RCM2)
The RCM2 Module can only be installed in LOC1 and LOC2 of any LP40 card. The purpose of the RCM2 daughter
board is to provide Caller ID decoders for use with that telephone company provided service over analog trunks.
In addition the RCM provides R2 MFC senders and receivers.These are not used in the US. This is the same RCM2
daughter board used on the OfficeServ 500 and 7200 systems.
The RCM2 consists of the following:
• Fourteen (14) CID receivers (for use with Caller ID on analog trunks).
• Sixteen (16) CID senders (to pass Caller ID from trunk to single line port).
MISCELLANEOUS FUNCTION MODULE (MIS)

2.2.2 SMARTMEDIA CARDS
An OfficeServ 7400 system must have a SmartMedia card installed in the main control processor (MP40) as the
SmartMedia card contains the system operating software.The SmartMedia card can also be used to store a back-
up customer database to supplement the database stored in NAND Flash. In addition the SmartMedia card can
store backup copies of the operating software for the LP40, and TEPRI cards.
2.3 INTERFACE CARDS
These cards provide the interface connections for telephone lines and stations to the KSU and expansion cabi-
nets.These cards fit into the universal card slots to configure the system as required.

grammed to be on continuously or flash at a programmable rate of 100ms to 2000ms ON/OFF times. The
16MWSLI does not contain any over-voltage protection and is not qualified as OPX. It also does not contain DTMF
receivers, but instead shares the system DSP resources. It can be inserted in any universal card slot in all cabinets.
Each port on this card is intended for connection to one telephone. Connecting multiple telephones to a port
may result in incorrect operation or damage to the card. This card supports the Power Fail Transfer feature. See
installation manual for details.

2.3.4 SPECIAL FEATURE CARDS
SVMi-20E
The SVMi-20E is designed to meet the demands of the sophisticated voice mail user with-out sacrificing simplic-
ity. The SVMi-20E is a self contained plug in (In-Skin) Auto Attendant and Voice Mail card.
The SVMi-20E may act as an Auto Attendant system only, a Voice Mail System only, or both. The SVMi-20E is
equipped with 4 Ports built onto the main PCB assembly and can handle 4 calls simultaneously.The SVMi-20E can
currently (at the time of this writing) be upgraded to 8 and/or 12 Ports by adding one or two 4 Port VPMs to han-
dle up to either 8 and/or 12 calls simultaneously.
On the SVMi-20E unit, no external line or power connection is necessary as it is an In-Skin product.The power and
telephone connections are accomplished directly through the phone system on the backplane edge connectors.
Because the SVMi-20E does not draw from the -48DC supply it has a Zero (0) SEPU rating under all possible con-
figurations.
Currently the Message Storage capacity, on the SVMi-20E is approximately 7 hours with the 128MB Compact Flash
configuration or approximately 140 hours with the Hard Drive configuration.
The modular design of the SVMi-20E allows it to be expanded to add voice ports as needed. Only one SVMi-20E
card can be installed in a system and another voice mail system can NOT be used in combination with the SVMi-
20E. This card can be installed in any universal slot.
2.3.5 DATA MODULES
The OfficeServ 7400 supports 4 enterprise class data modules as described below: They may be combined in the
same cabinets with the telephone system cards to provide a converged voice and data solution. As an alterna-
tive they can be installed in separate cabinets working independently of the telephone system as stand alone
data devices.
