This in-service support is currently achieved via a sole source contract with the Original Equipment Manufacturer (OEM) including a contractual arrangement for the management of the Shore Reference Sets (SRS) associated with the ICS.
ICS provides a digital and analogue voice message exchange architecture that supports voice communications over digital and wireless networks and analogue circuits. The system also includes a telephone exchange, secondary, emergency damage control (DC) communication systems, submarine broadcast and general alarm functions. A-Class ICS employs a wholly, complex, 3-node communication architecture that employs digital switch and network technologies within a multi-layer software model. It supports essential communications between the submarine crew for operational and safety critical functions on-board. The existing system in place is based on Integrated Services Digital Network (ISDN) and will need to move to the modern Voice Over Internet Protocol (VOIP) technology to allow long term support.
ICS is a complex system with many interfaces and nodes to allow personnel the opportunity to communicate throughout the platform. This complexity is not always understood by Ship Staff so it is essential to have engineering backup available via Suitably Qualified and Experienced Personnel (SQEP) ICS engineers provisioned for via a support contract. Astute ICS is a Priority 1 Master Equipment (ME) and is vital to delivering platform capability. The software will need to be a SIL2 (Safety Integrity Level) system and integral to the whole boat safety case.
