Processor read/write scratch memory (called CALL STORE) was implemented using a magnetic core variant called Ferrite Sheet. Program and Data Store (used to store Software and infrequently changed data) was implemented using a technology called piggy back twistor - in modern parlance a write once, read many times non-volatile memory system).
The Bell DataPhone 300 used the same protocol as the Bell 103. This modem is from 1978. The Bell 103 modem or Bell 103 dataset was the second commercial modem for computers, released by AT&T Corporation in 1963. [1] [2] It allowed digital data to be transmitted over regular unconditioned telephone lines at a speed of 300 bits per second.
H.323 is a system specification that describes the use of several ITU-T and IETF protocols. The protocols that comprise the core of almost any H.323 system are: [8] H.225.0 Registration, Admission and Status (RAS), which is used between an H.323 endpoint and a Gatekeeper to provide address resolution and admission control services.
IEC 103 uses FT1.2 (defined in IEC 60870-5-1) for frame format having options of Frame with variable length, Frame with fixed length & single character similar to IEC 101. Single character is used for acknowledgments, fixed length frames are used for commands & variable lengths are used for sending data.
The first serial type Class 103.1 was put into service on 27 May 1970. DB planned to introduce a new Intercity system with fast first class connections between major cities in autumn of 1971, so the specification sheet demanded Class 103.1 to be capable of pulling a 400-tonne (390-long-ton; 440-short-ton) train at 200 km/h (120 mph).
Contactless ICs that comply with parts 3 and 4 of ISO/IEC 14443-4 Type A with a mask-ROM operating system from NXP. The DES in the name refers to the use of a DES, two-key 3DES, three-key 3DES and AES encryption; while Fire is an acronym for Fast, innovative, reliable, and enhanced.
All types have a maximum collector current of 100 mA, except that the original Philips tentative data dated 4.4.1966 specified a maximum collector current of 100 mA peak (I CM) for the BC107/8/9, and Telefunken originally specified a maximum collector current of 50 mA for the BC109, but since at least 1973 all have revised collector currents of 100 mA average or 200 mA peak, except that the ...
The TTC had already started building a streetcar line that would extend from the end of the subway at Kennedy station to the Scarborough City Centre, a low-density route passing through industrial land. The TTC was not interested in changing to the ICTS for this route, until the Ontario government, which provided about 80% of the capital costs ...
