iSYS provides 24/7/365 emergency service on all of the various public address and intercom systems currently deployed on the MBTA. Most recently the MBTA replaced all of the existing station public address systems with a state of the art public address and variable message sign system. This computerized communication system provides up to date schedule information, delays, emergency notification and general public announcements both audibly and visually on the platforms and public areas in each transit station. A variety of other garage, car house and office intercom and paging systems are also supported.
