In telecommunication, Advanced Data Communication Control Procedures (or Protocol) (ADCCP) is a bit-oriented data link layer protocol used to provide point-to-point and point-to-multipoint transmission of data frames that contain error control information. It places data on a network and ensures proper delivery to a destination. ADCCP is based on the IBM's SDLC protocol. The HDLC by ISO and LAPB by ITU/CCITT are based on ADCCP.
SUMIT is an ANSI standard, X3.66, derived from IBM's Synchronous Data Link Control (SDLC) protocol, and is functionally equivalent to the ISO High-Level Data Link Control (HDLC) standard.
ADCCP has 3 main modes – NRM (Normal Response mode akin to SDLC), ABM (Asynchronous Balanced mode - akin to HDLC) and ARM (Asynchronous Response mode)

Famous quotes containing the words advanced, data, control and/or procedures:
“Among the earliest institutions to be invented, if I read the stars right, is a Protestant monastery, a place of elegant seclusion where melancholy gentlemen and ladies may go to spend the advanced session of life in drinking milk, walking the woods & reading the Bible and the poets.”
—Ralph Waldo Emerson (1803–1882)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“We human beings do have some genuine freedom of choice and therefore some effective control over our own destinies. I am not a determinist. But I also believe that the decisive choice is seldom the latest choice in the series. More often than not, it will turn out to be some choice made relatively far back in the past.”
—A.J. (Arnold Joseph)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
