	Frame slip - Wikipedia, the free encyclopedia
		Note: A frame slip should not be confused with a dropped frame where synchronization is not lost, as in the case of buffer overflow, for example.
		In the reception of framed data, a frame slip is the loss of synchronization between a received frame and the receiver clock signal, causing a frame misalignment event, and resulting in the loss of the data contained in the received frame.

	Terminal
		A pipeline terminal is a storage facility at the downstream end of a pipeline transport, typically serving as a buffer between delivery and use.
		In Telecommunication, the term is used to describe an apparatus to send and/or receive signals on a line, such as a telephone or (in the context of voice over IP) as a general term for network devices, telephones or other stations.
		Terminal symbol in BNF is an indivisible entity.

	Lakeville tables vote on telecommunications tower: 1/19/98
		Nextel Telecommunications of Lexington wants to build a 120-foot communications tower on rural, but business-zoned, land at 164 County St. It needs a zoning board variance of the town's 1996 bylaw mandating that towers in a business zone be no taller than 35 feet.
		Hanging over the zoning board is the Federal Telecommunications Act of 1996, which makes it difficult for towns to keep telecommunications towers out of their community.
		As it approved a hearing continuance, the board expressed concern that there is an adequate buffer zone between the tower land and abutters, and that alternative sites closer to the town's industrial zone have not been fully explored.

	Variable length buffer - Wikipedia, the free encyclopedia
		In telecommunication, a variable length buffer is a buffer into which data may be entered at one rate and removed at another rate without changing the data sequence.
		Note: Most first-in first-out (FIFO) storage devices are variable-length buffers in that the input rate may be variable while the output rate is constant or the output rate may be variable while the input rate is constant.
		Various clocking and control systems are used to allow control of underflow or overflow conditions.

	Formal validation of virtual finite state machines
		Index Terms- formal specification; software tools; telecommunication computing; finite state machines; program verification; electronic switching systems; formal validation; virtual finite state machines; formal validation tool; ATandT; 5ESS; telephone switching system; communicating processes; virtual finite state machine; super-trace algorithm; process interaction; deadlock; livelock; unexpected inputs; message buffer overflow; unreachable code; software development
		The tool validates networks of communicating processes implemented in the virtual finite state machine (VFSM) notation, using Holzmann's (1991) super-trace algorithm to check for errors in process interaction such as deadlock, livelock, unexpected inputs, message buffer overflow, and unreachable code.
		We discuss the extent to which the validator has been successfully employed in 5ESS software development, and describe our present research efforts to eliminate some of the roadblocks that stand in the way of its more widespread use.

	Space diversity system in PCM-TDMA telecommunication system using stationary communication satellite - Patent 4052670
		At the output of this dejitterizer 11, a length difference between fixed signal routes A and B is corrected by the fixed delay circuit 12a, which can easily be formed by a buffer memory or a shift register since the received signal of burst mode has been synchronized with clock pulses of the same station.
		In the buffer memory, it is enough to delay the read timing by a necessary time period from the write timing.
		An embodiment of the dejitterizer 11 (or 11a) is shown in FIG.

	CCSR - EPSRC projects - Variable-bit-rate speech coding - final report summary
		Variable rate coders are ideally suited for packet communication networks such as the Internet, ATM etc. However, they cannot be used over the existing telephony systems unless a long buffer is used to absorb delay variation which in itself will be detrimental since it will introduce longer end-to-end delay.
		By using internal funds, a multi-rate channel coding to complement the speech bit rates of 3.9, 5.2 and 6.8kb/s for the half rate GSM channel capacity of 11.4kb/s has also developed and submitted to the European Telecommunication Standards Institute (ETSI) as part of the Adaptive Multi-Rate GSM competition.
		In all rates the 10 LPC parameters were quantised in the form of Line Spectral Frequencies (LSF) using a split vector quantiser with a total of 28 bits/frame.

		The circuit consists of a dc-to-SFQ converter, ring oscillator[(RO) is a closed-loop RSFQ Josephson transmission line], confluence buffer, and an 8-bit binary counter.
		This cell is designed for a rapid-single-flux-quantum (RSFQ) telecommunication data switch.
		The input signal transforms to SFQ pulses, and each pulse resets the phase of the ring oscillator, giving a locking time of 1 bit.

		If packets are dropped by the network, or if a possibility of the Receiver Buffer emptying is acceptable, a statistical analysis would be necessary to determine play back delay.
		In the 'Bandwidth Glut' scenario espoused by DWDM believers and, to the chagrin of many telecommunication investors, the Stock Market, bandwidth is inexpensive and plentiful.
		As the mix continues to become even more heavily data oriented at the beginning of the 21st century, Internet technologies are now justifiably receiving considerable attention.

	Dejitterizer - Encyclopedia Glossary Meaning Explanation Dejitterizer
		A dejitterizer usually consists of an elastic buffer in which the signal is temporarily stored and then retransmitted at a rate based on the average rate of the incoming signal.
		In telecommunication, a dejitterizer is a device that reduces jitter in a digital signal.
		A dejitterizer is usually ineffective in dealing with low-frequency jitter, such as waiting-time jitter.

		Flaws in the implementation of these standards is now raising concerns that VoIP networks and users could be at risk of denial of service and buffer overflow attacks.
		Part of the reason video-conferencing hasn't grown into a mainstream application is thanks to H.323, a standard long-ago approved by the International Telecommunication Union (ITU) for audiovisual data transmission across networks.
		The standard is frequently used in everything from Cisco hardware to Microsoft Net-meeting.

		One way to deal with a message that doesn't stop is to use your telecommunication software's logging or text-buffer function.
		Fortunately, there are only two protocols that you're likely to run across: 8-1-N (which stands for "8 bits, 1 stop bit, no parity" -- yikes!) and 7-1-E (7 bits, 1 stop bit, even parity).
		If this had been a long message, it would just keep scrolling across and down your screen -- unless the people who run your public-access site have set it up to pause every 24 lines.
