AFTC5 is a highly configurable, jointless Audio Frequency Track Circuit. It is designed to operate between the interlocking and trackside AFTC equipment to vitally generate and receive rate-coded carrier for train detection and generate rate-coded carrier for speed commands to the train. Additionally, AFTC5 can generate and receive bidirectional non-vital train-wayside communication signals. AFTC5 eliminates the need for discrete wiring due to Ethernet communications with other AFTC5 units and interlocking processors. EASILY CONFIGURABLE — AT LOWER COST Parameters, such as frequencies, code rates, transmit/receive levels and IP addresses, are software configurable, allowing identical track circuit hardware to be used. AFTC5 reduces wiring costs using simple connections to the power supply, Ethernet, and trackside equipment. AFTC5 provides the clear advantages of accurate frequency transmission and reception and improved stability due to its digital signal processing capabilities. Environmental Operating temperature -40°F to 158°F -40°C to 70°C Storage temperature -67°F to 185°F -55°C to 85°C Vibration AREMA 11.5.1 Class C EMI/EMC AREMA 11.5.2 For more information please contact: abcd REMOTE DIAGNOSTICS Alstom’s Maintenance Management System (MMS) provides extensive diagnostic information for maintainers with remote or local access to perform preventive and corrective maintenance. MMS communicates with AFTC5 using Ethernet, collecting historic data measurements to determine overall track circuit health. AFTC5’s compact solution supports six track circuits in its 19-inch subrack. Typically four AFTC5 subracks can be mounted in a customer’s 19-inch rack, to support up to 24 track circuits.

ADT documents key technical features, capturing train detection, cab signaling, train-wayside communication, network and interfaced field equipment configuration data. Configuration data generated using ADT is flashed onto configuration keys used to program each TCU module. ADT supports efficient configuration when TCU modules require replacement and are reprogrammed using the configuration keys.
