Description
Bottom Line Up Front (BLUF): The MRC MED-100 is a hybrid marine electronic telephone switchboard (PABX) designed to merge traditional analog shipboard lines with modern VoIP, Wi-Fi SIP handsets, and satellite communications (VSAT, Inmarsat-Fleet). Capable of managing up to 200 extensions (including 128 analog lines) and 8 external trunk lines, it is certified to IEC 60945 with DNV GL and RMRS type approvals.
1. System Overview & Marine Engineering Architecture
Manufactured in South Korea by Marine Radio Co., Ltd. (MRC Korea), the MRC MED-100 Hybrid Marine IP Telephone Auto-Exchanger System represents state-of-the-art maritime equipment designed to fulfill stringent international safety conventions and classification requirements. Tested against severe marine vibrational dynamics, thermal cycling, and continuous electromagnetic interference (EMI), this equipment delivers mission-critical dependability for deep-sea merchant vessels, offshore rigs, workboats, and naval patrol vessels.
Featuring industrial-grade internal components, galvanically isolated power conversion stages, and robust ingress protection, the MED-100 prevents catastrophic single-point failures. Navigating officers and marine superintendents benefit from streamlined human-machine ergonomics, intuitive operational workflows, and verified compliance during annual safety and radio surveys.
