nanoSwitch Installation Guide General Information
nanoSwitch Telephone Exchange is a fully digital telephone system designed to meet the current
and planned future requirements of all internal and external telephone calls made on-board ship.
nanoSwitch system incorporates state of the art digital technology for command processing
and voice switching, using Pulse Code Modulation/ Time Division Multiplexing (PCM/TDM)
distributed switching matrix.
nanoSwitch is able to be bulkhead or rack mounted by turning the supplied brackets through 90
degrees.
The system architecture has been designed to allow a high level of software control over the
system’s hardware. The software has a large range of features and capabilities including Call
diversions and pickups, voice prompting etc
All of the features can be controlled at extension, group and user levels.
nanoSwitch has extra features for the marine environment including:
Ø External shore line, SATCOM, cellular and Public Address access
Ø AC and DC operation
Ø Priority intrusion
Ø Direct dial in and out with voice prompting (DISA)
Ø Voice prompting for features
Ø Modular construction
nanoSwitch supports up to 48 extensions for internal telephones, 6 external connections, 1 Public
Address interface and 2 uncommitted relays.
The exchange conguration (database) is held on an internal small ash card. The facilities within
the exchange can be changed to suit individual requirements using a Windows™ computer.
Programming is via USB on the processor board or via a network connection. Conguration and
log les can also be transferred to and from a PC using a small MMC card.
The exchange is requires an AC (90-260Vac) or DC (24V +/- 20%) power supply.
Every telephone and tie line can be individually congured to meet customer’s specic
requirements. Using a telephone equipped for Calling Line Indication (CLI) the caller’s telephone
number can be displayed on the receiver’s telephone unit.
The exchange is pre-programmed to provide specic features for 2 classes of extensions.
When connected to external lines, incoming calls are directed to a pre-specied extension.
Outgoing calls are enabled for Class A phones and can be dialled directly by prexing the
telephone number with a specic code.
Call-logging facilities are provided by the exchange to enable all internal, outgoing and incoming
calls to be logged. The information logged includes the source extension, user name, number
dialled and duration of the call. Output is through an RS232 serial interface for a printer.
The system uses -48V bias on telephone lines giving superior performance over 24V systems.
The volume on telephones can also be set electronically under engineering control to ensure
clarity in reception.
By adding or replacing plug-in modules, users can carry out future expansion and servicing of
the exchange. To assist with maintenance and fault nding, either the front LCD display or an PC
can be used.

The front panel has the 2 power switches, an LCD display and cursor buttons for navigating the
menu system.
Power Supply Unit (C4080)
The power supply is made up of 2 parts.
The AC (90-264V @ 50/60Hz) is converted to 48V DC, which is then
combined with the DC 24V (±20%) input to another power supply
which generates the system output voltage.
There is a no break when switching between the AC and DC
supplies. The status of the supplies connected to nanoSwitch as
displayed on the LCD.
There is one 5V DC output.
WARNING: There are high voltages in the power
supply section. Care must be taken when
replacing modules. ALL power inputs must be
removed  rst.

information from/to the other PCBs, controls feature
activation and PCM time-slot interchange.
The processor contains 32MB of DRAM and 32MB of
solid-state hard disk, which contains the con guration and
operating software.
The Processor card also provides announcements for voice
prompting and user greetings. The standard 64KBps PCM
signals are stored for high quality voice reproduction. Voice
Prompting is normally in English, but can be updated by
the user to any language or message.
On the card, there are connectors for an USB connection
to a PC or laptop.

nanoSwitch Installation Guide Site Preparation
General Site Considerations
The rst step is to locate an acceptable site for the equipment. When locating the mounting site,
the following points should be considered:
Ø nanoSwitch is designed for bulkhead mounting. The system must be rmly mounted to
the bulkhead to reduce the effect of vibration
Ø The location must have access to a dedicated 93-264 AC 50/60Hz circuit with a circuit
breaker or fuse rated at 2 Amps if using the AC power input.
Ø The location must have access to a dedicated 24 DC circuit with a circuit breaker or fuse
rated at 5Amps, if using the DC power input.
Ø The location must have access to a good earth ground
Ø The location should be well ventilated with a recommended temperature of 15°C to 25°C
and a relative humidity of 5% - 90% non-condensing. The area should be suitable for
ofce type equipment
Ø The equipment should be away from radio transmitting equipment, generators and other
equipment capable of generating electrical equipment. The system should be protected
from ooding and heavy machinery as well as excessive dust and vibration
Ø The location should have adequate accessibility, space and lighting for future servicing
Ø Telephone cables should be terminated in the integral Main Distribution Frame (MDF) or
to an external unit located within 3 metres of the telephone exchange
Check on-site Equipment
Once the equipment installation location has been identied and its suitability checked, verify
that all the equipment required is onboard and has not been damaged during shipment.
Unpack the nanoSwitch, checking that there is no damage. Check that the type and quantity of
boards received is correct and any optional equipment is available. A packing list is included with
all systems. Note that the individual boards should not be unpacked at this time.
If any equipment is missing or damaged,
notify Marine Communications Limited or your agent
to correct the situation.
Rack Based Systems
Where the system is part of a larger system such as entertainment centre then this will be rack
mounted as per the total system supplier’s instructions. Terminations for power and telephones
may be different than for the standard cased system.
PCB Installation
Boards must not be installed or removed with applied power
The system PCBs contain digital circuitry, which while extremely reliable, can be damaged by
exposure to excessive static electricity. When handling PCBs, a grounded wrist strap should be
used to protect the cards from static discharges. Also, use common sense when handling the
PCBs. For example, do not place a PCB in positions where heavy objects might fall on the PCB
and damage components.
