CHAPTER 1. Introduction to the
OfficeServ 7200
This chapter describes the features and major functions of the OfficeServ 7200 and
introduces the system architecture, interfaces, and programming.
1.1 Introduction to the System
The OfficeServ 7200 is a communication device, which is the most suitable for small
offices where less than 50 to 100 subscriber lines are used. Also, the OfficeServ 7200
allows the users to receive voice, data, and Internet services, which means that the
OfficeServ 7200 makes voice calls, and sends/receives data using data networks.
The 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.
1.1.1 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 by using the LAN/WAN
modules. The users can use the integrated wire/wireless platform (phones, PCs, servers,
mobile phones, or peripherals) to make communications easy.
SNMP Agent Function
SNMP agent module is equipped in MP 20 and MP20S, supports NMS (Network
Management System). MP 20 and MP20S can connect NMS, especially the OfficeServ
NMS of Samsung with SNMP.
Higher Quality IP Phone
The OfficeServ 7200 ensures the Quality of Service (QoS) of the voice calls depending on
the priorities and grouping of data and voice packets.
Layer 2 QoS: Priority Processing (802.1p), VLAN (802.1q)
Layer 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 WideArea Network (WAN) and Local Area Network (LAN) interface modules are
installed in the OfficeServ 7200; thus, data can be sent/received via the interface of the
10/100 BASE-T in both the external Internet and the internal Intranet without any data
equipment.
When interworking with the WAN Interface Module (WIM), the LAN Interface Module
(LIM) is operated as the managed LAN mode. At this time, WIM is mounted in the slot 1
and LIM is mounted in the slot 2 in the same rack.
If the LIM module does not interwork with WIM, and is used in any other slot, the LIM
module is operated as the unmanaged LAN switch mode.
The PLIM module is the switch that provides the Power over Ethernet (PoE) function.
Wireless LAN Services
The OfficeServ 7200 offers a wireless LAN solution for both wire and wireless services at
offices. The OfficeServ 7200 uses an Access Point (AP), which supports handoff and QoS.
Because the OfficeServ 7200 uses a wireless LAN base station, it allows the users to make
wire/wireless voice/data communications or access the Internet without establishing the LAN.
Also, an efficient and convenient working environment can be made at any time or place
because sophisticated mobile stations are used for the OfficeServ 7200.
A Variety of Application Solutions
The OfficeServ 7200 offers a variety of application solutions such as OfficeServ News,
OfficeServ EasySet, Internet Call Center, R-NMS, internal board-type voice mail solutions,
integrated facsimile servers, and digital integrated recording systems.
About Integrated and References
- ‘Integrated’ means that the OfficeServ 7200 interworks with the external solution
server and the system and server perform one integrated function.
- For detailed information about how to use each application solution, refer to the
User’s Guide of each application.
Easy Installation and Expandability
The OfficeServ 7200 can be easily installed as follows: the basic cabinet and expansion
cabinet of the OfficeServ 7200 are mounted on the 19-inch rack. Multiple service boards
can be additionally installed in universal slots of the cabinets.

OfficeServ 7200 System Description

1.1.2 System Architecture
The OfficeServ 7200 with MP20 is configured with a basic cabinet and expansion cabinet
mounted in a 19-inch rack. The Main Control Processor (MP20) is installed into the basic
cabinet and manages the entire OfficeServ 7200. It performs switching, processes signals,
or manages the phones. The expansion Local Control Processor (LCP), which is the sub-
control part, is installed into the expansion cabinet, controls boards, or sends/receives data
to/from the MP20. The OfficeServ 7200 with MP20S is configured with only a basic
cabinet mounted in a 19-inch rack. The Main Control Processor (MP20S) is installed into
the basic cabinet and manages the basic cabinet of OfficeServ 7200.
The other components are various interface boards, power modules, and fans.
The service configuration diagram of the OfficeServ 7200 is shown in the figure below:

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 PRIdigital trunk lines andsend/receive voicedata
through the trunk lines.They transmit the voice data of 64 Kbps per channel. 8 TRK (8 Trunk)
provides the Caller ID (CID) Path function and provides the Polarity Reverse Signal (PRS)
and Metering Pulse Detection (MPD) function as options. 8 TRK transmits/receives voice
by the analogue office line, and transmits 64 Kbps data information per each channel.
8 TRK2/16 TRK (8 Trunk2/16 Trunk) provides the Caller ID (CID) Path function and
provides the Polarity Reverse Signal (PRS) detection Metering Pulse Detection (MPD)
function is not supported. If 4TRM option board is mounted on the UNI board, it operates
as a voice trunk board and supports an analogue trunk line, and provides the CID & PRS.
Voice Station Part
The voice station part is configured with a Digital Line Interface (DLI), which interfaces
digital voice stations, and Subscriber Line Interface (SLI), which interfaces analogue voice
stations. Multiple DLI and SLIboards can be mounted in anyslots of the main or expansion
cabinet depending on the numbers of analogue/digital voice stations. 16DLI2 and 8DLI are
Digital Line interface boards. 16SLI2, 16MWSLI, and 8SLI2 are analogue Subscriber Line
interface boards. In addition, the hybrid-type 8COMBO2, which contains interface circuits
for analogue and digital stations. The UNI board equipped with 4SLM and 4DLM operates
as a voice station board in the same way.

Data Transmitting Part
The data module is configured with the WIM, which is a WAN interface board, and the
LIM, PLIM, PLIM2, GPLIMT and GSIMT which is a LAN interface board.
The WIM sends/receives data to/from the external Internet and provides ports for
connecting the internal network with a variety of external interfaces.
The LIM sends or receives data to or from the internal Intranet and provides an interface of
10/100 BASE-T. Also, the LIM functions as a switching hub. The PLIM and the PLIM2
provides a PoE functionality, a 10/100 BASE-T interface and a switching hub functionality.
The GPLMT provides a Layer 2 LAN interface to support the internal data network, as
well as a 10/100 BASE-T Fast Ethernet (FE) and a 1000 BASE-TX interface for the data
transmission. The GPLIMT can also be self-operated as a Managed Switch, regardless of
the WIM installation.

Voice Application Service Part
The voice application module consists of the VoIP that transmits the voice to the data
network. The MGI16 offers the VoIP function by converting voice into data.
The OAS offers the MGI, MFR, MPS function.
SVMi-20E provides the voice recording, AA, and E-mail send function to 12 users at the
same time by one SVMi-20E per system, as the voice mail process board of the built-in type.
Configuration of the Application
The OfficeServ 7200 provides the application software below:
The OfficeServ Solution and OfficeServAdmin have separate servers.
OfficeServ Solution (CTI, OfficeServ Operator)
OfficeServ Admin (Web Management, Installation Tool, OfficeServ EasySet)
