11 | About the Manual

1 Introduction
1.1 Product Description
The purpose of the Alphatron AlphaConnect maritime communication system is to give the seamen easy and reliable on-
board communication between all essential places on-board a ship, as well as giving the possibility of making telephone
calls to and from the ship, via satellite communication terminals.
The system:
• Enables internal calling between locations on-board
• Covering all normal telephone functions with telephone systems such as; calls, call transfer, priority, and wake-up
calls
• Calls via Satcom, GSM
• The system covers needs such as bells, rotary lights, headsets in technical spaces
The system has a type approval certificate by DNV and complies with the IEC60945 standard for maritime electronic
communication equipment, which will ensure years of problem free-operation.
12 | Introduction

1.2 Operational Features
This section gives an overview of some operational features.
1.2.1 On-board Communication
On-board conversations bridge, ECR, cabins, offices, work shop, deck etc. All locations, no matter if it is dry, wet, noisy,
or dirty, can be covered by either a Plain Old analogue Telephone Service (POTS) or one of our communication stations
with handset, headset, or loudhailer.
1.2.2 Distribute Sitcom
Calls from the ship to shore can be conducted from all places on-board. The seaman can have his privacy by calling the
family from his cabin for example. Calls from shore to ship can be distributed to all locations on-board, typically to bridge,
captain’s cabin or to ship office. It is not needed to be on the bridge to answer an incoming satellite call.
1.2.3 TalkBack
Communication stations AlphaConnect P211, AlphaConnect P411 and AlphaConnect P421 can be used to implement
the classical TalkBack functions. A call from bridge to mooring stations for example, can be set up from bridge, without
hands-on on deck. Groups of stations can be addressed simultaneously when performing a TalkBack (command group
conference) call.
1.2.4 PA Functions
The AlphaConnect communication system can distribute public address (acoustic paging) to all stations with
loudspeakers. The system gives possibility of defining groups with priority levels. The system can be set up to send a
gong signal preceding the spoken message. PA calls are initiated from telephones and communication stations, and
does not require special control stations with goose neck microphones. It is also possible to connect the AlphaConnect
to an external PA system, such as the Alphatron Marine AlphaAnnounce and, by use of pre-defined telephones and
communication stations, initiate PA calls.
1.2.5 Time distribution and wake-up
Using telephones with display gives the possibility for displaying the ships clock on the telephones. The time displayed
can be set manually by a simple telephone call. Based on the system time, wake-up calls can be ordered from any
telephone connected to the system.
1.2.6 Call data management (CDM)
A ship owner that wants to register calls made via the satellite equipment connected can make use of our CDM
system. The crew are given accounts and PIN codes which are used to open the access to the satellite lines. When
conversations are conducted, call data records are stored on the system disk. Based on these stored data, the
responsible officer can print invoices covering the telephone calls made.
Note the Call Data Management system is optional.

1.3.3 Communication Stations
Communication stations are advanced telephones mounted at each location that needs communication. Typically, for
locations such as the bridge, the engine control room and the steering gear room, a simple telephone is just not enough.
The following communication stations are available:
• AlphaConnect P211
• AlphaConnect P220
• AlphaConnect P411
• AlphaConnect P421
The AlphaConnect P211 communication station is mainly used as intercom, which can dial 3 pre-set numbers only. It has
no speaker, and is typically used in combination with a loudhailer.
The AlphaConnect P220 communication station is a full-duplex station, without hands-free functionality, therefore a
handset is required.
The AlphaConnect P411 and AlphaConnect P421 are advanced communication stations with many configuration options
accessible through an easy to use menu system. The AlphaConnect P411 and AlphaConnect P421 can also act as the
master for a TalkBack call.
