Applicability to France
Features specific to DTI requirements for France are implemented in

• transmission and reception of alarm indication signaling (AIS) in TS16
(card disabled, warm SYSLOAD, etc.)
• France-specific PPM counting
• decadic dialing
• France-specific alarm report and error handling
The 2Mb DTI pack uses a standard IPE-sized (9.5" by 12.5"), multilayer
printed circuit board. The faceplate is 7/8" wide and contain six LEDs.
