Introduction to the OfficeServ 7200
This chapter describes the features and functions of the OfficeServ 7200, including
the system architecture, interfaces and programming.
Note that, although all possible options, interfaces, modules, etc., are described in
this guide, some are country specific and, therefore, only available in the relevant
country. Refer to your reseller or distributor for more information if necessary.
1Introduction to the System
The OfficeServ 7200 is a communications system most suitable for small offices
where less than 50 subscriber lines are used. It allows phone users to receive voice,
data and Internet services, which means that the system makes voice calls and
sends/receives data using data networks. Users can easily make use of a variety of
phone functions and applications on various platforms such as digital phones, IP
phones, mobile phones and PC servers.
1.1 Major Functions
The major functions and features of the OfficeServ 7200 are described below.
Integrated Communication Environment
The OfficeServ 7200 makes voice calls and sends/receives data using LAN / WAN
modules. Integrated wired/wireless devices (phones, PCs, servers, mobile phones
and peripherals) are used for communication.
Next-generation Platform
The OfficeServ 7200 uses an IP-based feature server to provide an IP solution
which integrates the functions of mail servers, Session Initiation Protocol (SIP) serv-
ers, and Voice over IPUnified Messaging Service (VoIP UMS).

CHAPTER 1. Introduction to the OfficeServ 7200 OfficeServ 7200 General Description Guide
Page 1-2 © Samsung Business Communications
The IP-based feature server is a Linux platform and can continuously add feature
server modules to be provided in the future. Examples of the feature servers include
the mobile roaming server and the Authentication, Authorization and Accounting
(AAA) server.
Higher Quality IP Phone
The OfficeServ 7200 ensures the Quality of Service (QoS) of the voice calls de-
pending on the priorities and grouping of data and voice packets.
yLayer 2 QoS : Priority Processing (802.1p), VLAN (802.1q)
yLayer 3 QoS : Class Based Queuing (CBQ), RTP Priority Queuing, or the on-
demand management of the bandwidth Wide Area Network (WAN)
WAN/LAN Functions
The WAN and LAN interface modules are installed in the OfficeServ 7200; thus,
data can be sent/received via the 10Base-T/100Base-Tx interface in both the exter-
nal Internet and the internal Intranet without any data equipment.
Wireless LAN Services
The OfficeServ 7200 offers a wireless LAN solution for both wired and wireless
services in offices. The OfficeServ 7200 uses a combined Access Point (AP), which
offers services by separating the data from voice, and supports handoff and QoS.
Because the OfficeServ 7200 uses a wireless LAN base station, it allows users to make
wired/wireless voice/data communications or access the Internet without establishing
the LAN.
Also, an efficient and convenient working environment can be established at any
time or in any place because sophisticated mobile stations are used for the Office-
Serv 7200.
Text-To-Speech (TTS) Responses
The OfficeServ 7200 converts text messages such as e-mails to voice messages and
allows users to listen to their messages through phones. Also, it recognizes the
voices and responds to them.
Mail Server and Instant Messaging
The OfficeServ 7200 integrates voice messages and e-mails to function as an e-mail
server which converts the integrated messages according to users’ needs and re-
sends them, and sends/receives instant messages.

OfficeServ 7200 General Description Guide CHAPTER 1. Introduction to the OfficeServ 7200
© Samsung Business Communications Page 1-3
Application Solutions
The OfficeServ 7200 offers a variety of application solutions such as OfficeServ
News, OfficeServ EasySet, Internet Call Center, R-NMS, internal module-type voice
mail solutions, integrated facsimile servers, and digital integrated recording systems.
- ‘Integrated’ means that the OfficeServ 7200 system and the external server
perform a single integrated function.
- For information on how to use each application, refer to the relevant User’s Guide
for each.
Easy Installation and Expandability
The OfficeServ 7200 is easily installed: the basic chassis and expansion chassis are
mounted on a 19-inch rack. Multiple service modules can be installed in universal
chassis slots.
1.2 System Architecture
The OfficeServ 7200 is configured with a basic chassis and expansion chassis
mounted on a 19-inch rack. The OfficeServ feature server is mounted on an exter-
nal Linux server.
The Main Control Processor (MCP) is installed in the basic chassis and manages
the entire system. It performs switching, processes signals and manages the phones.
The expansion Line Control Processor (LCP), the sub-control part, is installed in
the expansion chassis: it controls the modules and sends/receives data to/from the
MCP. The other components are various interface modules, power modules and
fans.
The service configuration of the OfficeServ 7200 is shown below.

CHAPTER 1. Introduction to the OfficeServ 7200 OfficeServ 7200 General Description Guide
Page 1-4 © Samsung Business Communications
Figure 1.1 Service Structure of the OfficeServ 7200
Voice Trunk Line Part
The voice trunk line part is configured with digital trunk lines and analogue trunk
lines. The TEPRI modules interface the E1,T1, or PRI digital trunk lines and
send/receive voice data through the trunk lines.They transmit voice data at 64 kbps per
channel. The 4BRI modules interface with BRI T or S points and transmit voice data
at 64 kbps per channel. The 8TRK modules perform Polarity Reversal Signalling
(PRS), Metering Pulse Detection (MPD) and Caller ID (CID) detection in a module
and send / receive voice data via analogue trunk lines. Data is transmitted at 64 kbps
per line.
Voice Station Part
The voice station part is configured with a Digital Line Interface (DLI) which inter-
faces digital voice stations, and a Subscriber Line Interface (SLI) which interfaces
analogue voice stations. Multiple DLI and SLI modules can be mounted in any slots
of the main or expansion chassis depending on the number of analogue/digital voice
stations. 16DLI and 8DLI are Digital Line Interface modules. 16SLI, 16MWSLI
and 8SLI are analogue Subscriber Line Interface modules. In addition, there is a
combination type 8COMBO which contains interface circuits for analogue and
digital stations.

Data Transmitting Part
The data module is configured with the WIM, a WAN interface module, and the
LIM, a LAN interface module. The WIM module sends and receives data to and
from the external Internet and provides ports for connecting the internal network
with a variety of external interfaces. The LIM module sends and receives data to
and from the internal Intranet and provides a 10Base-T/100Base-Tx interface. It al-
so functions as a layer 2 switch.
The 4DSL module offers services to data subscribers up to 1 km away from the in-
ternal Intranet. Subscribers can use the Ethernet service within a transmission dis-
tance of 1.2 km.
Voice Application Service Part
The voice application module consists of the VoIP that transmits the voice to the
data network and the WLAN that transmits the voice wirelessly. The MGI module
offers the VoIP function by converting voice into data. If used, the 4WLI module
uses a Digital Adaptor for Subscriber Loop (DASL) to connect to the wireless BTS
(Combo type) and sends/receives voice to/from the phone system and wireless BTS.
The 4WLI accommodates up to four BTS (Combo) and 48 subscribers. If not used,
the wireless BTS (Basic type) is connected to the LAN only and accommodates 40
BTS and 120 subscribers
Application Configuration
The OfficeServ 7200 has a commercial server on a Linux platform outside of the
OfficeServ 7200 chassis which provides the following application software.
yMail server
ySIP server
yVoIP-UMS
OfficeServ Solution and OfficeServ Admin have separate servers.
yOfficeServ Solution: CTI, OfficeServ Operator
yOfficeServ Admin: Web Management, PCMMC, OfficeServ EasySet, System

3 Programming
MMC programs are used to change the data used for system settings and operate at
three levels: technician (or system) level, customer level, and station (subscriber)
level. Subscribers can only program MMCs accessible at station level. A password
is required for technician-level and customer-level programming but not for
subscriber programming.
Technician-Level Programming
All MMCs can be programmed at this level. Programming can be done using any of
the display phones in the OfficeServ system.
Customer-Level Programming
A customer can only program the MMCs specified in MMC 802 (Customer Access
MMC Number). Programming can be done using any of the display phones in system.
Subscriber-Level Programming
Programming can be done only for an individual subscriber’s phone.
