MEMORY
The system operates using stored program control. This program is stored on either a Multimedia Plus (MMC+) or
a Secure Digital (SD) media card inserted into the Main Processor card (MP40). The 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.
DEVICE MANAGER
The OfficeServ 7400 provides two methods to program the system from a personal computer. Access the system’s
embedded Device Manager programming interface using Internet Explorer 6.0 or higher for convenient web
based access. Another method is to use the stand alone proprietary version of Device Manager running on any
PC that meets the minimum requirements. Both methods allow programming from anywhere in the world pro-
vided there is a LAN/WAN or modem connection. Device Manager permits a technician to access and program
the system on-site and remotely and also 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 or a modem, a PC can access the OfficeServ 7400 system remotely (off-site) to make database
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 or MP20 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 details. See figure 1.9, 1-10, and 1-11 for possible hardware combinations.
