&KDSWHU Introduction
1.1 General Description
The Marine Communications Limited MicroSwitch marine telephone exchange has been
designed to meet the special requirements of all internal and external telephone calls made on
board ship.
The key features of the MicroSwitch are:
•Internal communications
•Shore line, PA and SATCOM access
•Priority intrusion
•PC programmable
•Direct dial in and out
•Call logging
•Modular construction
•Automatic fax detection
•Music on hold
The MicroSwitch supports up to 32 extensions and 8 external lines, enabling connections to
shore lines, SATCOM and Public Address lines. Facilities are available to enable a maximum
of 4/8 connection circuits to be made at any time. The circuitry is enclosed in a compact case
for easy fitting to bulkheads.
The MicroSwitch priority intrusion facility enables a caller to interrupt a call currently taking
place on another extension.
The exchange is pre-programmed to provide specific facilities for Officer Class and Crew
Class extensions. These facilities are held within the exchange memory and can be changed to
suit individual requirements by using a telephone or an IBM PC (or compatible). The memory
is provided with its own battery support and any changes made to the set-up will be
maintained in the event of the exchange being disconnected from the power supply.
When connected to the external lines, incoming calls are directed to a pre-specified extension.
Outgoing calls are enabled for Officer Class phones and can be dialled directly by prefixing
the telephone number with a specific code.
Call-logging facilities are provided by the exchange to enable all outgoing and incoming calls
to be logged. The information logged includes the source extension, the number dialled and
the duration of the call. Output is through an RS232 serial interface.

Future expansion and servicing of the exchange is carried out simply by adding or replacing
plug-in modules. To assist with maintenance and fault finding, a number of indicators are
provided on the modules to show the status of the exchange and the extension lines.
MicroSwitch will detect an incoming fax call tone and automatically transfer it to the
designated extension.
In the event of a power failure external lines are connected directly to specified extensions.
Please note that satisfactory performance cannot be guaranteed for every allowed combination
of host and subsidiary apparatus, in particular, certain modern electronic phones when set to
LD mode may not be recognised correctly.
CAUTION
microSwitch is designed for use on board ships. It may not comply with
specific statutory requirements such as EMC/PTT standards for use on
land based applications.

1.1.3 Environmental Specifications
The MicroSwitch exchange has been tested and meets with Lloyds Register ENV2 type
approval requirements.
Temperature
Operating
Storage 0 to +55 deg C
0 to +70 deg C
Humidity 5 to 95% relative humidity
Vibration 1.0mm amplitude at 2 to 13.2Hz
1g at 13.2 to 100Hz
1.1.4 Power Supply
It is recommended that the microSwitch is not powered directly from the ship’s emergency
supply as this will increase the background noise heard on the extensions.
1.2 Requirements
An IBM PC (or compatible) with a serial interface and the microAid program or a DTMF
telephone are required to program a MicroSwitch exchange.
1.3 MicroAid
microAid is a software utility to enable you to reconfigure the MicroSwitch. Full details about
microAid are provided in the microAid help file which is available from Marine
Communications Limited at the address given in the front of this handbook.
1.4 Extension Facilities
The MicroSwitch extensions are grouped into two user categories:
•Category A - Officer Class extensions
•Category B - Crew Class extensions
In addition there are Engineering facilities which are only available through a PIN access
code.
The Officer Class and Crew Class facilities are described in the MicroSwitch User Manual;
the Engineering facilities are described in this manual.

&KDSWHU Installation
2.1 Pre-Installation Checks
Before unpacking the MicroSwitch exchange, check the packing carton for signs of damage.
Any damage to the carton should be reported to the supplier before proceeding.
Open the carton, carefully remove the contents and check for any signs of mechanical
damage.
Check that the documentation is present:
MicroSwitch User Manual
2.2 Physical Installation
The MicroSwitch should be installed in a location away from electrical noise and excess
vibration. Where possible the equipment should be located in a well ventilated area where it
will not be adversely affected by salt water and extremes of heat.
When locating the unit make sure you can access the modules and cable connectors.
Clearance should be allowed on each side of the case to avoid contact with neighbouring
equipment through vibration and shock.
The unit is supplied with the lid unsecured. This is to allow you to fit the lid so that it opens
either right handed or left handed depending on which is most convenient. In Figure 2-2 the
lid is hinged to the left.

2.3 Locating The Unit
Figure 1 identifies the cabinet dimensions. Please refer to these when you are locating the
MicroSwitch in its permanent position.
Figure 1 Cabinet Dimensions
Loosely fit the top screw and manoeuvre the cabinet so that the screw slots into the top hole
on the rear of the cabinet. There is a covering cap on the hole for the top screw which needs
to be removed in order to place the unit and replaced once the unit has been placed and the
screw tightened. The bottom two screws are accessed from the front of the cabinet. See
Figure 2 on the next page.
