OfficeServ 7200 System Description

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 Wide Area 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.

2.4.5 Keyset Daughter Board (KDB)

5000 Series Keyset Daughter Board

DS-5014D, DS-5021D and DS-5038S keysets support one of 3 different types of daughter board installed on them to enhance operation or to provide an additional local port, depending on the type of daughter board.

KDB-Digital Line Interface (KDB-D)

If your keyset is connected to a Digital Line Interface (DLI) port that supports 2B + D operation, you may install a daughter board that provides a Digital Line Interface (DLI) port for connection of a digital station device such as a keyset or 64 button add-on modules.

KDB-Subscriber Line Interface (KDB-S)

If your keyset is connected to a Digital Line Interface (DLI) port that supports 2B + D operation, you may install a daughter board that provides a Subscriber Line Interface (SLI) port for connection of a standard telephone device such as a cordless phone.

KDB-Full Duplex (KDB-F)

The standard speakerphone mode of operation for 2-line LCD keysets is „half duplex‟. This means that you cannot transmit and receive speech at the same

time. Adding a KDB-F to your keyset will convert the speakerphone into full duplex mode, enhancing its operation. In addition, the KDB-F may have up to 3 external microphones attached to it for conference room type applications. These microphones require an „EXTMIC‟ key programmed on the keyset to activate or deactivate them.

Mode Band

The mode band in the previous table represents the quality of the multi-mode

optical fiber relative to the transmission speed. The unit is generally represented in MHz.Km, the optical signal’s bit rate (the flickering rate of the optical signal) multiplied by the maximum transmission distance. The higher value means farther transmission of higher optical signal with higher bit rate. When using the shortwave laser and the long-wave laser, a mode band is also specified for each type.

Categories of UTP Cable

UTP Cables are classified into Straight-through UTP cable and Crossover UTP

cable. The Straight-through UTP cable is used for connecting the LIM or PLIM module of OfficeServ 7200 to other modules (MP20, MGI16, WIM). The Crossover UTP cable is used for connecting only LIM (PLIM) module to LIM (PLIM) module.
