Experts of the company successfully deployed an IP Internet Protocol-based telephony solution onto the motor vessel.
The IP Telephony solution comprises five major components:
- Cisco CUCME or CUBE enabled routers for telephony call control.
- Voicemail and automated attendant (optional).
- Cisco Catalyst switches with inline power for the Cisco IP Phones and Cisco Aironet AP. The switches provide advanced QoS services that ensure highquality voice on the network.
- Cisco IP Phones that serve as endpoints. All Cisco IP Phones contain a built-in data switch that allows users to connect computers to the network, thus reducing the number of ports required on the Catalyst switches.
- Cisco Aironet 1200 Access points provide QoS for Cisco wifi enabled IP phones
All the systems deployed have been configured for remote administration and management. Management tasks can be performed from any computer on the network with Telnet or HTTP browser access.
The aim of this project was to deliver the IPTP Networks solution to vessels. IPTP provides Entertainment, Communication and Information via a single, dual head high-availability Satellite Dedicated Link.
- Cisco IP Telephony on a high-end router running Cisco Callmanager Express, allowing to serve on-board local, as well as the outgoing and incoming calls. The Cisco Callmanager Express has been configured to support seamless failover;
- Ability to place 20 simultaneous incoming/outgoing phone calls to and from the vessel by utilizing voice transmission equipment over the satellite link;
- Integration of IP Telephony with 40 analog lines through FXS/FXO (Foreign Exchange Subscriber/Office) ports allowing to use the existing analog phones and external GSM/Inmarsat lines as part of the telephony system;
- Integration of IP Telephony with International VoIP system and compatibility with global VoIP telephony, allowing to place free of charge calls;
- Integration of IP Telephony with GSM Network system allowing to place and receive calls from GSM phones to the IP phones directly;
- Integration of IP Telephony with INMARSAT service allows passing call through, in case the primary links are unavailable, for certain predefined IP Phones;
- PLAR (Private Line Auto Ringdown) and DID (Direct-Inward-Dial) functionalities that will enable 24 UK telephone numbers and 2 Cyprus numbers to be received on specific IP Phones;
- Ability to use Cisco wireless IP Phone handsets in the same way as the fixed IP Phones;
- Call functionalities such as call waiting (dual line), call transfer, call hold, conference call, call forwarding, call pick up, intercom, call history and DND (Do Not Disturb);
- Remote manageability of the IP Telephony system;
- Local on-board manageability through web-based GUI (Graphic User Interface);
- Integration with billing platform, allowing to have detailed CDR (Call Details Record) per room/cabin, provided DID is not hidden.
IP Telephony/ Ethernet/ Wireless 802.11 b/a Network Solution
The Ethernet and wireless network systems deliver:
- Redundant Network topology with dynamic fail-over links by utilizing Rapid SpanningTree protocol;
- 8000 Mbps (8Gbps) full-duplex redundant backbone trunks between core switches;
- Switched Ethernet 100Mbps full-duplex connections for the terminal equipment;
- Cisco POE (Power over Ethernet) provisioning for the IP Phones and wireless Access Points, utilizing the network cabling for providing power to the equipment;
- Wireless dual-band 802.11b/802.11a coverage of the specific areas;
- Transparent roaming of phones and laptops between the access points without interruption;
- Provision of QoS for voice traffic in the wireless network with dot1Q;
- Provision of QoS for voice and video in Ethernet switched network with dot1Q VLANs and dot1P CoS (Class of Service);
- Remote manageability of network switches and wireless Access Points.
The GSM Distribution Network proposed on the motor vessel used STP Cat 5 cabling to carry 1.8 GHz RF signal between NIB (Network In The Box) and GSM antennae installed in different decks on the board. The system covers all decks and a 400m diameter space. The solution will focus on providing one single NIB that feeds the entire network.
The GSM system has been designed to provide the following:
- Complete on-board GSM network that integrates an MSC (Mobile Switching Center), a BSC (Base Station Controller) and a BTS (Base Transceiver Station), working in the 1800 Mhz frequency. The GSM Distribution Network uses STP Cat 5 cabling to carry 1.8 GHz RF signal between NIB and GSM antennae installed in different decks on the board. The system covers all board space;
- Capacity of up to 14 simultaneous calls;
- Ability to make free of-charge-calls from on-board registered GSM mobile phones to IP telephones within the vessel;
- Ability to make free of-charge-calls from an on-board registered GSM mobile phone to another on-board registered GSM mobile phone;
- Ability to make calls free-of-charge from on-board registered GSM mobile phones to international destinations through VoIP;
- Ability to receive free-of-charge incoming calls from the ship’s IP Telephony to the on-board registered GSM mobile phones;
- Roaming of the GSM phones for incoming and outgoing calls, provided that interconnection agreement with land-based GSM provider is established;
- Remote manageability of the GSM Network.
