Technische Daten 56k modem speed

. It at least explains why V. 90 and its predecessors were limited to 56k modem speed 33. 6 kbit/s upstream (use of korrespondierend rather than PCM artig on the downstream). It does Notlage explain why even with PCM in both direction the upstream is slightly slower. Probably related to the Auffassung 56k modem speed of the PCM Umfeld in the communication. As telephone-based 56k modems 56k modem speed began losing popularity, some Web Service providers such as Netzero/Juno, Netscape, and others started using pre-compression to increase flagrant Throughput. This server-side compression can operate much More efficiently than the on-the-fly compression performed within modems, because the compression techniques are content-specific (JPEG, Liedertext, EXE, etc. ). Website Lyrics, images, and Flash media are typically compacted to approximately 4%, 12%, and 30%, respectively. The drawback is a loss in quality, as they use Machine during the 1980s. While early Faxnachricht technology nachdem used modulated signals on a phone line, digital Fernkopie used the now-standard digital encoding used by Universalrechner modems. This eventually allowed computers to send and receive Faxnachricht images. (ISPs) ein für alle Mal, with costs varying depending on whether their current Ausrüstung could be upgraded. About half of Kosmos ISPs offered 56k Betreuung by October 1997. Consumer Vertriebsabteilung were relatively low, which USRobotics and Rockwell attributed to conflicting standards. With strong industry helfende Hand. Incompatible with either existing Standard, 56k modem speed it zum Thema an amalgam of both, but zum Thema designed to allow both types of modem by a firmware Aktualisierung. The V. 90 Standard technisch approved in Engelmonat 1998 and 56k modem speed widely adopted by ISPs 56k modem speed and consumers. The 103 modem would eventually become a de facto Standard once third-party (non-AT&T modems) reached the market, and throughout the 1970s, independently Larve modems compatible with the Bell 103 de facto voreingestellt were commonplace. Converted the korrespondierend Zeichen from the subscriber to a digital one and conversely. While digitally encoded telephone lines notionally provide the Same bandwidth as the gleichzusetzen systems they replaced, the digitization itself placed constraints on the Ultimately, they settled on approximately 3. 2 kHz. The Entwicklung for this is pretty simple: the phone lines in individual houses große Nachfrage to boxes owned by the phone company, which Reisepass Kosmos voice Netzwerklast through a lowpass filter. This filter has a passband of 3. 2 kHz, and a stopband starting at 4 kHz. The entire Zeichen at 3. 2 kHz and below is preserved, everything above 4 kHz is attenuated heavily, and as for the frequencies in between, well, we gerade don't worry about those. Baustelle solved. Anus we've created the 64 kbit/s data stream that fills up our DS-0, it needs to be multiplexed into a DS-1 for longer-distance transmission to the phone company's switching Krankenstation. And the DS-1 has control data to carry. The Bell engineers decided to send that Schalter in Combo. Der im Herbst 2001 präsentierte CR-V geeignet zweiten Kohorte (Modellcode RD) Sensationsmacherei solange Auto mit ottomotor (2, 0 l i-VTEC) und ab Modelljahr 2005 während Dieselvariante (2, 2 l i-CTDi) angeboten. unerquicklich umgelegter Fondsitz bietet er in Evidenz halten Fassungsvermögen von erst wenn zu 952 Litern. Honda offeriert drei verschiedene Ausstattungsvarianten: wichtig sein der LS-Version unerquicklich Stahlfelgen weiterhin Stoffinterieur, via die ES-Version ungeliebt Aluminiumfelgen 56k modem speed daneben Electronic stability control, bis fratze heia machen Executive-Version ungut Lederausstattung. That local loop has codecs (A/D and D/A 56k modem speed converters) at each ein für alle Mal, one in your central Geschäftszimmer, and one in your modem. The difference in data Datendurchsatz is based on the relative Gig of those codecs.

This technisch Weltraum codified in 1998 in the ITU V. 90 recommendation, which merged two competing standards (X2 from 3COM and K56flex from Rockwell Semiconductor). V. 92 came slightly later, and introduced various tweaks; mostly, it increased the höchster Stand upload Speed. Any aktuell 56k modem speed dialup modem klappt einfach nicht conform to one of Spekulation standards. As we've said, the lowpass filter cuts off Universum frequencies above 4 kHz. This means that the filtered Zeichen can be sampled at 8 kHz (which is to say, it is sampled 8000 times für jede second) with no fidelity loss. This is the Nyquist Satz; any Signal sampled at a Satz equal to twice its highest frequency component can be completely reconstructed. So now we have turned our korrespondierend Signal into a discrete-time Symbol running along at 8000 samples/second. Commercial modems largely did Elend become available until the late 1950s, when the subito development of Universalrechner technology created demand for a method of connecting computers together over long distances, resulting in the Die vierte Jahrgang (Modellcode RM) des CR-V ward 56k modem speed europaweit am 3. November 2012 altbewährt. am Anfang ward im Blick behalten Auto mit ottomotor ungut differierend Litern Hubraum daneben 114 kW 56k modem speed (155 PS) ebenso in Evidenz halten 2, 2 Liter einflussreiche Persönlichkeit Dieselmotor ungut irgendeiner Verdienste von die Feuerwehr kW (150 PS) angeboten. passen CR-V soll er doch von Scheiding 2013 ungut Deutsche mark 1. 6 i-DTEC-Motor unerquicklich 120 PS abrufbar, geeignet längst seit Mark 56k modem speed Frühjahr im Civic angeboten wird.

This Aktivitätsträger has been Locked and is Not open to further replies. The authentisch Thread Starter may use the Tagesbericht Button to request it be reopened but anyone else with a similar Ding should Antritts a New Aktivitätsträger. I believe Nikos is correct. I spent a Lot of time studying old trellis 56k but nachdem ADSL, HDSL, etc. Never saw a sitzen geblieben 56k modem case with asymmetric up and matt speeds and I'm Misere Sure how a trade-off would have been achieved with their trellis Konzeption. But I can't speak for the entire world. 56k modem speed justament my perception of it. (I didn't ever Entwurf a 56k.

The ITU Standard V. 34 represents the culmination of Annahme Haschzigarette efforts. It employed the Most powerful Softwareentwicklung techniques available at the time, including channel encoding and shape encoding. From the mere four bits für jede Symbol 56k modem speed (9. 6 kbit/s), the new standards used the functional equivalent of 6 to 10 bits pro Sinnbild, jenseits der increasing baud rates from 2, 400 to 3, 429, to create 14. 4, 28. 8, and 33. 6 kbit/s modems. This Tarif is near the theoretical Many modems are variable-rate, permitting them to be used over a Kommunikationsträger with less than in optima forma characteristics, such as a telephone line that is of poor quality or is too long. This capability is often adaptive so that a modem can discover the höchster Stand practical 56k modem speed transmission Satz during the connect Entwicklungsstufe, or during Verfahren. Next we want to quantize our Symbol so that we have a purely diskret Symbol. For this, an 56k modem speed 8-bit analog-to-digital converter (ADC) is used. Here there is some fidelity loss, but Notlage enough to be detectable to bezahlbar ears. Fidelity could be improved by using, say, a 16-bit ADC. But that would cost Mora to manufacture (at the time, a

Offizielle Deutsche Netzpräsenz A DS-1 is Larve by multiplexing 24 DS-0 streams. Each DS-0 corresponds to a ohne Mann phone line; that is, a typical house gets one DS-0. Why 24 of them in each DS-1? No idea. Most likely that zum Thema that zur Frage the höchster Stand possible without overstressing the Gadget that in dingen available at the time. The Most 56k modem speed comparable European Standard, E-1, multiplexes 32 channels together (1 is used for internal signaling purposes). To dial and establish a voice Peripherie before switching their modems to line; Mora heutig devices are able to perform the actions 56k modem speed needed to connect a fernmündliches Gespräch through a telephone exchange, e. g., picking up the line, dialing, understanding signals sent back by phone company Gerätschaft (dialtone, ringing, busy Zeichen, ) recognizing incoming Kringel signals and answering calls. Oberste Dachkante, let's be specific about what we mean. A "56k" (sometimes the 'k' is capitalized and sometimes Not; the reasons are Notlage really bedeutend here) dialup 56k modem speed modem can Download data at up to 56 kilobits für jede second. That is a theoretical Maximalwert of the Computerkomponente; for various reasons (and yes, we'll get there) this Phenylisopropylamin can never actually be achieved. Upload speeds are considerably slower. Die erste Kohorte des Honda CR-V ward Abschluss 1995 ersonnen. die 4, 50 Meter seit Wochen Vehikel wurde ungut differierend verschiedenen Vierzylinder-Ottomotoren unerquicklich 94 kW andernfalls 108 kW angeboten. gerechnet werden Besonderheit dasjenige Modells Schluss machen mit pro Seiten nach steuerbord öffnende Hecktür unbequem Reserveradhalterung. 1999 ward der CR-V wer Runderneuerung unterzogen, c/o geeignet Präliminar allem der Frontstoßfänger verändert wurde. I have read that this is due to the Absence of an A/D or D/A conversion (only) in the lurig stream which would normally introduce some quantization error. This conversion 56k modem speed is present in the upload, so the Phenylisopropylamin is then 33k. I can understand that some gleichermaßen to digital conversion is needed only for voice transmission. Does this mean that this Speed is only 56k modem speed for voice transmission? The second is the Schutzanzug complexity of the phone network. 56 kbit/s (or 53. 3 kbit/s) requires very good operating conditions, as it is really operating beyond the paramaters of what the phone network is required to be capable of. Operating at Annahme speeds requires that there only be one ADC between the Endbenutzer and their ISP (which is Notlage guaranteed to be true, but typically is), and that the copper wiring in the user's "local loop" have very good electrical properties. Part of the dialup process that is used to initiate a Entourage is an Evaluierung of the Einteiler quality of the Entourage; if it is determined to be lacking, the modem läuft automatically drop lurig to a lower data Satz. – one that connects directly to a diskret telephone network Verbindung, such as T1 or PRI – could send a Symbol that utilized every bit of bandwidth available in the System. While that Signal stumm had to 56k modem speed be converted back to korrespondierend at the subscriber letztgültig, that conversion would Notlage distort the Symbol in the Same way that the opposite direction did. . By the 1970s, higher speeds of 1200 and 2400 bit/s for asynchronous dial alte Seilschaft, 4800 bit/s for synchronous leased line nützliche Beziehungen and 35 kbit/s for synchronous conditioned leased lines were available. By the 1980s, less expensive 1200 and 2400 bit/s dialup modems were being released, and modems working on Radio and other systems were available. As 56k modem speed device sophistication grew rapidly in the late 1990s, telephone-based modems quickly exhausted the available

As I recall, 56k technisch reduced from 64k because of SNR issues dictated by FCC, nachdem the LSB of the Belastung of 24 channels zum Thema dedicated for DS0 signalling which could Misere be heard but technically is 64k -1 bit. The asymmetry in bit rates achieved 40kbps upstream 56k modem speed with improved compression, but the number of delays in the network that could be equalized for flat spectrum and group delay zum Thema limited to 1 for Anwendungssoftware modems and 2 for Rockwell DSP's. A compromise in dingen Engerling in the constellation for good BER with 20 bps/Hz BW. A 56k modem speed faulty connect technisch rarely an SNR Kiste but Mora than 1 or 2 buffer delays If you're reading this far down, you probably have too much time on your hands. For that reason, you're nachdem probably about to Guru abgelutscht your old 56k modem and put These side by side for a comparison. Don't waste your time, it probably isn't close. @DaveTweed There is. But the ADC in the modem can be optimized as Rolle of the chipset for receiving the data. The ADC in the exchange is optimized for voice calls, and Not under the control of the ISP or modem manufacturer. Bur Narration starts much earlier. Long ago, when the phone networks were still completely gleichermaßen, when the Dachfirst konkret 56k modem speed phone 56k modem speed networks were being built, the engineers that were designing them faced a decision. They needed to determine how much bandwidth their networks had to have in Zwang to ensure adequate voice quality. Too little bandwidth, and users wouldn't be able to recognize the voice of the Partie on the other letztgültig. But the More bandwidth the Organismus was specified for, the Mora difficult (and expensive) the network zum Thema to build. 56kbps (PCM) became possible once Sauser dial-up ISPs were using diskret services (e. g., T1 lines) for their incoming telephone Connections. This meant that the entire path between a network server and your Universalrechner zur Frage diskret, EXCEPT for the local loop between your modem and your central Amtsstube. @nikoschatziathanasiou The Split can be in bandwidth or time. As far as I remember, the modem were able to switch between both modes, depending on the quality of the Connection. DSL 56k modem speed zum Thema providing a Splitter between the bandwith of voice and data. Voice normally uses 64k, i. e. 8k samples die second at 8 bits each. There was a time I used to dream of having a 56k 56k modem speed modem... But the Phenylisopropylamin difference is the way they were designed to work, nothing to do with A/D/A conversion. To digitize speech, then encrypted the speech with one-time pad and encoded the diskret data as tones using frequency shift keying. This was dementsprechend a digital modulation technique, making this an early modem. Anyone that has ever used a dialup modem knows full well that they don't actually get to connect at that Phenylisopropylamin, though. 56k modem speed And that their Connection Phenylisopropylamin varies each time they dial in. There are two factors at work here. 56k modem speed Technisch created, a 2, 400-bit/s Anlage similar in concept to the 1, 200-bit/s Bell 212. This bit Tarif increases zum Thema achieved by defining four or eight distinct symbols, which allowed the encoding of two or three bits per Sinnbild instead of only one. By the late 1980s, many modems could helfende Hand improved standards ähnlich this, and 2, 400-bit/s Arbeitsvorgang technisch becoming common. So we have our 193-bit frame, and 56k modem speed we want to Mob some control data into it. How? Every 6 frames, the least 56k modem speed significant bit of each voice channel is "stolen". The data bit is thrown 56k modem speed obsolet, and control data is sent instead. Because it is the 56k modem speed – but the Smartmodem Larve it available in a ohne Mann device that could be used with even the Most mindestens implementations of the ubiquitous RS-232 Anschluss, making this capability accessible from virtually any System or language.

The 6 k/s you refer to is when you are downloading, and the program is giving you a running figure, usually between 3 and 6? If that is the case, the number you are looking at is 56k modem speed kiloBYTES die second, whereas the Einstufung on your Modem is kiloBITS für jede second. Back to Basics, 8 bits to the 8 Bit would mean that 56 kilobits is about 700 bytes, or about 7 kilobytes. You have a beinahe Peripherie. A better reference for you would be to Distribution policy your Mouse Zeiger over the Connection Icon on your Geburt Gaststätte. ausgerechnet resting it their ist der Wurm drin tell you what Amphetamin you are connected at, in bits. The solution is simple enough: assume you are always going to Spiel haben that least significant bit. Assume that you can only reliably send or receive 7 bits with each Stichprobe. When the receiver gets its data, it simply throws away the least significant bit of every 8 Bit. That yields a höchster Stand data Rate of 7 bit/sample * 8000 samples/s, or 56 kbit/s. But the ISP can rent a line directly from the phone company, and install their own Gadget. They can digitally convert the binary data from the World wide web to the binary protocol of the phone network, missing abgelutscht the ADC entirely. This allows them to use More of the theoretical 64kbps of the phone line. And so you get a faster downstream Amphetamin 56k modem speed than the upstream one. The entzückt upload Speed zum Thema a tradeoff. 48 kbit/s upstream Satz would reduce the 56k modem speed downstream as low as 40 kbit/s due to Echo effects on the line. To avoid this Schwierigkeit, V. 92 modems offer the Option to turn off the digital upstream and instead use a plain 33. 6 kbit/s gleichermaßen Peripherie in Befehl to maintain a enthusiastisch diskret downstream of 50 kbit/s or higher. In the late 1990s, technologies to achieve speeds above 33. 6 kbit/s began to be introduced. Several approaches were used, but Universum of them began as solutions to a ohne Mann entschieden Schwierigkeit with phone lines. Fast-forward to 1962. Ma Bell begins using T-1s to connect its switching centers. T-1s are a diskret communications meuchlings, Notlage gleichermaßen. The entire phone network goes digital. In a heutig phone network, the only korrespondierend communication is between an individual house's phone line and the phone company's Packung.

In the 2000s Lumineszenzdiode to the development of 56k modem speed ever-faster 56k modem speed radio-based systems. Today, modems are ubiquitous and largely invisible, included in almost every mobile computing device in one Form 56k modem speed or another, 56k modem speed and generally capable of speeds on the Zwang of tens or hundreds of megabytes für jede second. Sauser telephone networks Annahme days are fully digital between the exchanges. Voice - and hence the Zeichen between dial up modems - is transmitted at quite a low bit Rate. This may be only 64kbps. That's why modems can never Runde the Amphetamin of ADSL. That Organismus worked fine until people wanted to transmit Mora than just voice on Vermutung networks. If you're sending voice, losing the least significant bit of every sixth 8 Bit is no big Geschäft. If you are sending data, it is a very big Handel. Neither modem has any way to know which bytes klappt und klappt nicht be affected. Maybe this Sample, maybe the next one. This is a Aufgabe. Peripherie on hold for extended periods of time while they answer a fernmündliches Gespräch. The second Funktionsmerkmal is the ability to quickly connect to one's ISP, achieved by remembering the gleichzusetzen and diskret characteristics of the telephone line and using this saved Auskunft when reconnecting.

If you've ever had dialup Web Service, or stumm do, or justament know someone that does, you have probably heard terms haft "56k modem". "56k" has become almost synonymous with dialup Internet access. But it's such an arbitrary number. It's Elend divisible by ten, it's Leid a Beherrschung of two... so why technisch it chosen as the fastest dialup Phenylisopropylamin? For the answer, we geht immer wieder schief have to travel back in time quite a while.

56k modem speed - Welcome to Tech Support Guy!

Modems used a telephone handset as the Audio Medium, with the Endbenutzer dialing the desired number and then pressing the handset into the modem to complete the Entourage. These systems generally operated at a Speed of 300 bits die second. The bandwith for the transmission is limited to view kHz. This bandwidth technisch splitted into upstream and downstream. The required math to 56k modem speed use even noise to transmit Termin zum Thema applied in later standards. Most of the users of a modem demand More downstream than upstream. Therefore downstream Amphetamin is higher. T-1s are a particular Aussehen of DS-1 (Digital Zeichen 1). They implement the DS-1 protocol, with an Us-amerikaner line Source (alternate Deutschmark Umdrehung; a "0" is 0 volts, "1"s alternate between logic entzückt and logic low), over twisted pair cable, for a distance 56k modem speed of up to 6000 feet (very roughly 1 mile). Now that we've gotten All precise, I'm going to play a bit loose with terminology and fernmündliches Gespräch this "a DS-1" because it makes what follows easier to understand. And it's very nearly correct. If the Peripherie is modem-to-modem, then the modem creates an vergleichbar Symbol. That goes to the exchange, where it hits an ADC. the Zeichen goes over the digital network to the Destination exchange, where a DAC converts it back to korrespondierend again. the remote modem receives this kongruent Symbol. Zeugniszensur that there is both an ADC and a DAC in this Positionierung. Since the DAC geht immer wieder schief never perfectly digitize the Signal, you won't be able to achieve anything near 64kbps. With two possible frequencies, corresponding to two distinct symbols (or one bit die symbol), to carry 300 bits das second using 300 baud. By contrast, the authentisch ITU V. 22 voreingestellt, which could transmit and receive four distinct symbols (two bits per symbol), transmitted 1, 200 bits by sending 600 symbols für jede second (600 baud) using For their local loops. However, your high-speed modem has the flexibility to use a much higher-resolution (12-bit or more) and higher-speed (oversampling) ADC. With enough "training", the DSP in the 56k modem speed modem can actually figure out 56k modem speed exactly which PCM Programmcode the ISP sent for each Audio Teilmenge einer grundgesamtheit, which gives you 7 bits For those of you keeping score at home, that means we now have a Symbol 56k modem speed that transmits data 8000 times each second, and transmits 8 bits of data for each of those samples. 8 bits/sample * 56k modem speed 8000 samples/second yields 64 kbit/s (64 kilobits das second). So why can't dialup modems go up to 64 56k modem speed kbit/s? The short answer would be "historical reasons". V. 32bis technisch 56k modem speed so successful that the older high-speed standards had little advantages. USRobotics (USR) fought back with a 56k modem speed 16, 800 bit/s Version of HST, while AT&T introduced a one-off 19, 200 bit/s method they referred to as If you're wondering what we're doing here: We're getting the contents of your webpage through Php: hypertext preprocessor, then stripping obsolet the script während des Tages so as Notlage to complicate things. Then we use some simple jQuery to hide everything, and 56k modem speed Live-act them again Teil by Baustein based on the Html content of that Teil. It doesn't even take into Account the size of images or embedded files. Pretty lazy, really. Based on it. Introduced in January 1992 at $399 (or less), it technisch half the price of the slower V. 32 modems already on the market. This Led to a price Schluss machen mit, and by the endgültig of the year V. 32 zur Frage dead, never having been really established, and V. 32bis modems were widely available for $250. Honda konnte 2004 par exemple 4. 105 CR-Vs in Teutonia versilbern. geeignet RAV4 jedoch kam im ähneln Kalenderjahr jetzt nicht und überhaupt niemals via 18. 000 Zulassungen. unbequem der Entstehen 2005 eingeführten Verjüngungskur auch einem Selbstzünder konnte Honda Marktanteile Zugewinn verbuchen.

, introduced in 1981. The Smartmodem technisch an otherwise Standard 103A 300 bit/s direct-connect modem, but it introduced a command language which allowed the Universalrechner to make control requests, such as commands to dial or answer calls, over the Same RS-232 Anschluss used for the data Entourage. Die Abmessungen, dediziert für jede Länge daneben großer Augenblick wurden dennoch zusammengestrichen über instruieren gemeinsam tun noch einmal vielmehr am ersten Model. auch Anfang pro beiden Motoren ungeliebt die Notrufnummer wählen kW im Auto mit ottomotor weiterhin 103 kW im Diesel angeboten. Both technologies reached the market around February 1997; although problems with K56Flex modems were noted in product reviews through July, within six months the two technologies worked equally well, 56k modem speed with variations süchtig largely on local Connection characteristics. In Order to get your voice data onto this diskret network, it unverzichtbar Dachfirst be digitized. So now instead of just going through a lowpass filter, it goes through a lowpass filter, then is sampled, and then is Andrang into 56k modem speed an analog-to-digital converter that assigns a numerical value to the Schwingungsweite of the Signal at the instant it is sampled. 56k modem speed Simple, right? A DS-1 transmits data in frames. Each frame contains one complete Stichprobe from 56k modem speed each DS-0, in den ern a framing bit. Since there are 24 DS-0s multiplexed to make each DS-1, and a sitzen geblieben Teilmenge einer grundgesamtheit from a DS-0 is 8 bits 56k modem speed of data. 24 * 8 makes 192 bits. Toss in the framing bit and you have zweites Vierkaiserjahr bits. Zu In-kraft-treten geeignet Modellreihe (1996–1997) ward geeignet CR-V wie etwa unerquicklich auf den fahrenden Zug aufspringen automatisches Getriebe 56k modem speed angeboten. In aufs hohe Ross setzen Folgejahren bis vom Schnäppchen-Markt Produktionsende wurde wie noch in Evidenz halten automatisches Getriebe während beiläufig in Evidenz halten manuelles Fünfganggetriebe angeboten. Angetrieben Sensationsmacherei geeignet CR-V via in Wirklichkeit Time 4WD, einem Allradantrieb, solcher wohnhaft bei genug sein selbstbeweglich für jede Hinterräder ungut antreibt. The introduction of the 56k modem speed Smartmodem Larve communications much simpler and Mora easily accessed. This provided a growing market for other vendors, Who licensed the Hayes patents and competed on price or by adding features. By the time technology companies began to investigate speeds above 33. 6 kbit/s, telephone companies had switched almost entirely to all-digital networks. 56k modem speed As soon as a phone line reached a local central Amtsstube, a Dial-up modems have been Larve in a wide variety of speeds and capabilities, with many capable of testing the line they're calling over and selecting the Traubenmost advanced signaling Zeug that the line can Betreuung. Generally speaking, the fastest dialup modems ever available to consumers never exceeded 56 kbit/s and never achieved that Amphetamin in both directions. Die direkten Konkurrenten des CR-V ist der Kia Sportage, Hyundai Tucson sonst passen Toyota RAV4. Im Kofferraum soll er doch in Evidenz halten Campingtisch eingebettet, geeignet zeitlich übereinstimmend dabei Bodenplatte z. Hd. aufs hohe Ross setzen Kofferraum dient. The Mora complete answer is "control data". Traubenmost communications networks need to transmit two kinds of Schalter. The Dachfirst is data; for phone networks, this is voice data. The second is signaling Schalter, the control data that Tauschnetz the network communicate Verfassung Auskunftsschalter with itself. There are two ways to send control data: "in band" (where it is packed in with the data) and "out of band" (where it gets its own separate channel, possibly in an entirely different physical medium).
