1.7 TECHNOLOGY

MEMORY
The system operates using stored program control.This program is stored on a SmartMedia card inserted into the
Main Control Processor card (MCP2) and contains sixteen Megabytes of NAND-Flash memory. The Smart Media
card also provides space for a backup customer database and a backup operating program. The system boots
from a 1 Megabyte boot ROM and downloads the operating program into thirty two megabytes of DRAM on the
Main Control Processor (MCP2) card. The customer database is stored in four megabytes of non-volatile SRAM.
MICROPROCESSORS
The OfficeServ 500 uses distributed processing. Its primary processor is a 32 bit Motorola MC68360 operating at
a clock speed of 50 MHz on the MCP2 card.This provides all the processing necessary for a single cabinet system.
In a multi cabinet system the secondary level of processing is on the SCP2 card for the first cabinet and on the
LCP2 cards for the expansion cabinets. These secondary processors are MC68302 processors running at 16 MHz
and provide local control of each cabinet. The tertiary level of processing is done in the keysets. The digital key-
sets use a Hitachi H8 processor for data communication within the system.

1.8 PROGRAMMING

The OfficeServ 500 is a self-configuring system.This means that immediately after applying power, the OfficeServ
500 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 stations are
assigned three or four digit numbers according to the settings of the switches on the MCP2 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 LCD display keyset without interrupting system operation. 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 con-
trolled by a different security passcodes and access procedure.
The OfficeServ 500 also allows the use of a proprietary computer program called SAPM-PCMMC. This permits a
technician to program the system using a personal computer. SAPM-PCMMC can be used 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 modems, SAPM-PCMMC can
access the OfficeServ 500 system remotely (off-site) to make database changes or perform uploads or downloads
of the customer database as if the technician were on-site.

1.9 SOFTWARE VERSIONS

The OfficeServ 500 system can be equipped with one of two versions of software to meet different customer
needs.
M VERSION-RELEASE 2
This version of software provides the software features for a single cabinet system and requires only the MCP2
card to run.
L VERSION-RELEASE 2
This version of software is required to run a multiple cabinet system although it can be used in a single cabinet
environment. For L version software to operate correctly each cabinet must have its own "Local" processor card
installed in it, that is the SCP2 for the first cabinet and the LCP2 for the second and third cabinets. In addition, in
a multiple cabinet environment, the MCP2 card MUST have an ESM daughterboard installed in position D1.
