Maritime Voice and Data Communications in Port and at Sea

Drastically reduce the cost of maritime voice and data communications over satellite links for passengers and crews on ships at sea and at port. Any solution must support both analog telephony as well as GSM, along with analog radio, Ethernet and dedicated data systems.

Extending maritime voice and data communications services to ships at sea and in port can be an extremely expensive proposition, when uplinking via costly satellite or microwave connections. Compressing or optimizing voice circuits can significantly reduce bandwidth requirements, lower costs yet maintain toll quality voice. Further savings can be realized by integrating voice and data services in one network.

 

The Vmux family of voice compression and optimization devices enables both carriers and owners to reduce costs of maritime voice and data communications by maximizing their existing network.

• Vmux voice trunking gateways provide up to16:1 voice compression, significantly reducing the bandwidth required for digital telephony access.

• Vmux A-bis optimization gateways reduce bandwidth requirements for cellular backhaul by up to 3:1.

 

Ships at port wanting to transmit telephony and LAN services over line of sight microwave links can employ the Vmux-110, which includes router functionality and support for FXS, FXO and E&M voice ports.

• 16:1 voice compression along with 3:1 Abis optimization ensures maximum reduction of voice transmission costs

• VAD and silence suppression optimize bandwidth utilization, leaving more room for data transport

• TDM and IP uplinks support all types of VSAT terminals
