PART 1. SITE REQUIREMENTS
To install the DCS-816 system, choose a site that meets the following requirements.
ü
Select a location for the Key Service Unit (KSU) that has enough space for easy installation
and adequate lighting. (KSU dimensions [mm]: 465 (H) x 315 (W) x 120 (D))
ü
ü
Select a location that minimises cable lengths. See the Cable Requirements table below.
The equipment should not be exposed to direct sunlight, corrosive fumes, dust, constant
vibration or strong magnetic fields such as those generated by motors and copy machines.
ü
A direct commercial AC power outlet is required. Do not use extension cords. Preferably, a
dedicated circuit should be used to minimise the risk of other electrical equipment being
connected that could adversely affect system operation.
ü
ü
ü
ü
Ensure that all wires and cables going to and coming from the KSU are properly routed. Do
not cross fluorescent lights or run parallel with AC wires.
The equipment must be located in an environment that will maintain a temperature range of
32°F ~ 104°F (0°C ~ 40°C) and a humidity range of 10% ~ 90% non-condensing.
Allow at least 150 mm clearance on both sides and 150 mm clearance on top of the KSU to
ensure proper ventilation.
Do not install within a 2-mile radius of broadcasting antenna or in close proximity to a fire
sprinkler head or other sources of water.
Meeting these requirements will help to ensure proper performance and greater life expectancy of
the system.

PART 2. INSTALLING THE BASIC KSU
2.1 SYSTEM CONFIGURATION AND CAPACITY
The DCS-816 system consists of the Basic Key Service Unit (KSU), option cards, trunk interface
cards, interface modules and digital keysets. The KSU is a single metal cabinet, and in its basic
form has 16 station ports: twelve (12) keyset ports and four (4) SLT (single line telephone) ports.
Additionally, the KSU contains one (1) trunk expansion slot, two (2) option connectors and
miscellaneous circuits: one (1) external page interface, one (1) general-purpose dry contact and
one (1) music interface selectable to internal built-in music (a melody chip) or external music.
Two types of telephones can be connected to the system: proprietary digital stations called
"keysets" that connect to Digital Line Interface (DLI) ports and standard telephone sets, generally
called "single line telephones", that connect to Single Line Interface (SLI) ports.
The Trunk Expansion slot provides an option to select an analogue trunk card or a basic rate
interface (BRI) card.
The DCS-816 system also has some option cards to provide serial I/O ports or AA facilities.
The KSU starts with two (2) analogue trunk ports and 16 stations, and the trunk expansion slot
provides a maximum capacity of 10 trunk ports (analogue or digital) and 16 stations.
The system maximum capacity is as follows:
Stations

2.4 GROUNDING THE KSU (Figure 2-2)
DCS-816 comes equipped ready to use with the third wire AC ground provided through the power
cord. This ground will be adequate for most applications. However, if it is suspected that there is
a problem with the ground provided at the AC outlet, or local codes require a solid earth ground to
be connected to the KSU, the existing third wire ground must be disconnected before power is
applied. The grounding lug on the KSU must be connected to a ground rod or metal cold water
pipe using #10 AWG (approximately 2.6 mm in diameter) solid copper wire. (See Figure 2-2.)
Failure to provide an adequate ground may cause unpredictable operation or even circuit failure.
Warning
Unplug the power cord from the AC outlet before attempting to connect the ground.
Hazardous voltage may cause death or injury. Observe extreme caution when working
with AC power.
GROUNDING THE KSU
2.5 MDF CABLING (Figure 2-3)

2.6 External Battery Connection (Figure 2-4)
It is recommended that an external battery should be installed to backup the system in case of AC
power failure. The DCS-816 system is equipped with battery charging and discharging circuits to
interface with an external battery.
To decide the capacity of the battery, keep in mind that it may damage the system if too large
while it cannot backup the system long enough if too small. The capacity should be not less than
6AH nor more than 26AH. The battery voltage should be 48 volts.
To connect an external battery, first pick out the battery connection cable through the MDF cable
path. Connect the RED lead of the cable to the positive (+) terminal of the battery and the BLACK
lead to the negative (-) terminal. Then insert the housing connector into the header in the power
supply.
NOTE: The actual connection should be done as the final step in the installation of the KSU.

2.7 Selecting Options on the Basic KSU (Figure 2-5)
There are some hardware options to select in the Basic KSU: Memory Backup Selection, Music
Source Selection and MPD/PRS selection for the two (2) analogue trunk lines on the base board.
2.7.1 Memory Backup Selection
The system is equipped with 256Kbyte of data memory and memory backup circuitry (a super
capacitor) to protect the data in case of any power failure. The memory backup circuitry has a
shunt-pin switch to enable backup. Before shipment, the switch is set OFF to prevent the super
capacitor from discharging during shipment and storage, and it should be switched ON after
installing and programming the system. Otherwise, the customer data and the programmed data
will be lost in the event of a power failure. (See Figure 2-5.)
2.7.2 Music Source Selection
The Basic KSU is equipped with a melody chip to provide music to stations and trunk lines as
Music-on-Hold or Background Music. In addition, it has an interface for an external music source,
(CD player, radio etc).
As the system provides only a single music channel for Music-on-Hold or Background Music, refer
to Figure 2-5 to select the music source at the end of installation. A shunt-pin switch selects the
music source: the internal melody chip or an external music source.
How to connect the external music source is explained in Part 7.
2.7.3 MPD/ PRS Selection and Installation
The Basic KSU has two (2) analogue trunk interfaces and each trunk interface is equipped with a
socket to install an option chip for Metering Pulse Detection (MPD) or Polarity Reverse Signal
(PRS) detection. (See Figure 2-5 for position of option chip sockets and ensure that the chips are
firmly inserted into the sockets.) One chip per line. DCS option chips for MPD or PRS can be
installed.

4.3 PCB Verification
Before connecting all MDF cabling, plug in a test cable to the Champ connector on the base board
(Figure 2-3). Connect a display set and verify that it is working.
Use maintenance program MMC 727 (System Version Display) to verify the system version and
software version and to confirm the status of installed cards. Otherwise, please contact your
dealer for advice.
Remove the test cable and plug in an amphenol-type cable and an RJ-45 cable to the MDF.
Proceed with the rest of the installation.
4.4 Default Trunk and Station Numbering
At the beginning of system operation the CPU reads the expansion slot and the option connections
for the presence of a card and identifies the type. It stores this as the default configuration.
The system assigns trunk numbers beginning with 701. Station numbers begins with 201. The
keyset connected to the lowest port is assigned to the operator by default and all incoming trunk
calls ring the station until the default data is changed by programming.
Station and trunk numbers can be changed, rearranged and reassigned as needed using program
MMC 724 (Dial Numbering Plan).

The DCS-816 system provides special programming and hardware for a customer-provided Voice
Mail / Auto Attendant (VM/AA) system. All SLI circuits are designed to provide a disconnect signal
required for VM/AA operation. The system requires MDF connection for single line telephones
and all connections can be made through the RJ-45 connector on the base board. See Figure 2-3
and refer to section 2.5 (MDF Cabling).
Use one pair twisted wires and connect each system/device to the SLI port of your choice via the
RJ-45 connector on the base board.

7.10 Information on DCS-816 Serial Interface (Figure 7-8)
There is a variety of data terminal equipment and data communication equipment at sites and
sometimes it may be confusing how to connect the equipment to the SIO card. Generally, the
connections described in sections 7.5 to 7.7 are sufficient to work most equipment. However, the
following, more detailed information, should help if you encounter any problems.
SIO BOARD (DTE DB9)

DSR (6)
RTS (7)
CTS (8)
RI (9)
Output, Transmitted Data, Essential

Signal Ground, Reference, Essential
Input, DCE Ready, Essential, Replaced with DCD sometimes
Output, Request to Send, Optional
Input, Clear to Send, Not Connected
Ring Indicator, Not Connected
INFORMATION ON SERIAL INTERFACE
The signal “ DSR (6)” is pulled-up with a resistor in the serial interface which meets the
requirements of most data equipment. However, some printers cannot operate with the pull-up
resistor and may cause trouble. If so, DCD (1) may replace DSR (6).
For signalling protocol, all parameters can be adjusted with relevant programming (MMCs 725 and
804) and the default settings are as follows:
Serial Port 1: PCMMC
Serial Port 2 : SMDR
SIO Protocol
1 Start bit, 8 data bits, 1 Stop bit, No parity
9600 Baud rate, No DSR check, 3 times retry

PART 8. CHANGING SOFTWARE (Figure 8-1)
In order to easily replace the system software, it may be necessary to partially disassemble the
KSU. Follow this procedure step by step.
1. Read carefully the instructions released with the new software or contact your distributor or
dealer for advice.
2. Remove the KSU front cover.
3. Check the memory backup switch on the base board and do as instructed.
In most cases it is recommended you keep the switch ON to prevent data loss.
However, new software sometimes needs to change the database structure, and this
requires you to clear all the data. If so, you will have to set the switch OFF and
reprogram the system after replacing the software (you will need to store user data on
your PC or write it down on paper). Contact your distributor or dealer for advice.
4. Remove the external battery (if installed) and switch OFF the system.
5. Remove the four EPROMs (U703, U704, U705 and U706) from the base board using a chip
extraction tool or by gently prising with a small, flat-bladed screwdriver. Put the removed
EPROMs aside carefully in case you need to reinstall them.
6. Remove the new EPROMs from their protective package and check that the legs of the
EPROMs are straight. Carefully insert the new EPROMs into their designated sockets.
7. Switch the system ON and verify that it is operating. If the system fails to operate, switch the
system OFF and replace the new EPROMs with the old ones. Contact your distributor or
dealer for advice if you cannot fix the trouble by yourself.
8. If the system operates satisfactorily, switch the memory backup switch ON and replace the
cover. Reconnect the external battery, if installed.
9. Program the system if required.
