ST5451 HDLC and GCI controller is a CMOS circuit fully developed by STMicroelectronics and diffused in advanced 1.2 m HCMOS3 technology.
The device is intended to be used mainly in ISDN applications, in Terminal (TE) and in Line Terminations (LT).
ST5451 can handle HDLC packets either on 16Kbit/s D channel or 64 Kbit/s B channel; it can work with a wide range of PCM signals going from GCI (General Circuit Interface) to DSI (Digital System Interface) to any PCM-like stream.
ST5451 is a complete GCI controller designed to comply with the GCI and GCI-SCIT (Special Circuit Interface for Terminal) completely handling Monitor (M) and Command/Indicate (C/I) channels.
ST5451 can be easily controlled by many different kind of microprocessors or microcontrollers having either non-multiplexed or multiplexed bus structure.
ST5451 can be used in connection with ST5420/1 S Interface Devices (SID-mW and SID-GCI) and ST5080 Programmable ISDN Combo (PIC) in Terminals and with ST5410 U Interface Device (UID) in Line Terminations.
