\nKes on v\u00e4hemalt korra kuulnud modemiga Internetti \u00fchendamist telefoniliini kaudu, ei unusta seda kunagi. Mitteasjatundjate jaoks ei ole see eriti melodiline helide kooslus. Kuid neile, kes s\u00f5ltusid modemisuhtest, on need helid nagu maagiline muusika. <\/p>\n

Praegu, aastal 2019, on dial-up enamikule muutunud vanaks ja ebavajalikuks tehnoloogiaks. T\u00f5epoolest, aeglane \u00fchendus, mis katkeb just siis, kui on k\u00f5ige huvitavam, v\u00f5iks j\u00e4\u00e4da minevikku. T\u00e4na r\u00e4\u00e4gime mitte \u00fchendusest, vaid seadmetest, mis seda tagasid \u2014 mineviku legendaarsetest modemitest.
\n <\/a><\/noindex>
\nJa mitte k\u00f5igist modemitest, vaid nendest, mis suutsid tagada suhteliselt stabiilse \u00fchenduse kodumaisetes telefoniliinides ja automaattelefonikeskustes. \u00dchenduse kiirus oli siis madal (see on pehmelt \u00f6eldud) \u2014 paljude jaoks oli 28800 bitti sekundis juba \u00f5nn, r\u00e4\u00e4kimata 56000-st. Siis saabus ADSL-i ajastu, ja see oli t\u00f5eliselt \u00f5nnelik hetk, kuid sellest r\u00e4\u00e4gime teises artiklis; praegu \u2014 modemitest!<\/p>\n

\nT\u00f5en\u00e4oliselt algas paljude lugejate tutvumine internetiga just selle modemiga. Toona n\u00e4is see erakordselt modernne seade (ja see oligi). See oli \u00fcks oma aja populaarseimaid modemeid, kuna t\u00f6\u00f6tas edukalt ka k\u00f5ige vanematel telefoniliinidel.<\/p>\n

Selle arendust viis l\u00e4bi ZyXEL koos Venemaa partneriga, kes aitas modemi kohandada SR\u00dc tegelikkusele. Modemi aluseks on ZyXEL BSI, pluss t\u00e4iendavad funktsioonid, nagu h\u00e4\u00e4landmete t\u00f6\u00f6tlemine ja automaatne numbri m\u00e4\u00e4ramine, mis vastab Venemaa (\u00fctleme, endise N\u00f5ukogude) standarditele. See on \u00fcks v\u00e4heseid modemeid, mis on saanud sertifikaadi Venemaa Sideministeeriumilt.<\/p>\n

Modem toetab k\u00f5iki standardprotokolle, sealhulgas V.32bis, samuti ZyX kaubandustootemarkide protokolle 19,2 ja 16,8 kbit\/s, pluss mobiilside tulekindel protokoll ZyCELL.<\/p>\n

Modem hoidis \u00fchendust mitmeid tunde (kuigi mitte k\u00f5ige k\u00f5rgema kiirusese), samas kui konkurendid pidid \u00fchenduse katkestama juba poole tunni p\u00e4rast.<\/p>\n

\nVeel edasiarendatud modem oma aja jooksul. Selle aluseks on TMS340 signaaliprotsessor ja Intel 80C186 \u00fcldine juhtprotsessor, mille tarkvara on v\u00e4lja t\u00f6\u00f6tatud ettev\u00f5tte inseneride poolt. Eksisteeris kaks versiooni modemist \u2014 Ameerikasse ja Kanadasse ning rahvusvaheline versioon.<\/p>\n

Viimane versioon kasutati SR\u00dc-s, kuna modem oli kohandatud liinide jaoks, mis vastasid Euroopa standarditele. Kohandamine t\u00e4hendas, et modem toetas \u00fchendust liiniga, millel olid k\u00f5rgemad pidevad ja vahelduvad pinged. Antud mudelis oli ette n\u00e4htud ka galvaniline isolatsioon liinide ja \u00fclej\u00e4\u00e4nud skeemi vahel. Nii et kui liiniga juhtus midagi, ei p\u00f5lenud ei modem ega sellega \u00fchendatud PC.<\/p>\n

Modem toetas suurt hulka sideprotokolle, sealhulgas V.32terbo ja V.FC. Samuti kasutas ta USR-i firmas loodud protokolli HST (High Speed Transfer \u2014 kiire andmeedastus). T\u00e4nu sellele t\u00f6\u00f6tas seade kahe kanali p\u00f5him\u00f5ttel \u2014 \u00fcks oli kiire andmete edastamiseks ja vastuv\u00f5tmiseks, teine aga aeglane, mis t\u00f6\u00f6tas eranditult teenuste andmete, nagu pakettide \u00fclekande, taaskasutusetaotluste jms edastamiseks.<\/p>\n

Modem hoidis \u00fchendust pisut halvemini kui ZyXEL modem. Peale selle, kui signaal halvenes, v\u00e4hendati automaatselt kiirus. Kui k\u00f5ik taastusin, t\u00f5usis kiirus taas.<\/p>\n

\nModem USB-liidesega, mis s\u00e4ilitas tuttava kujunduse ja indikaatorid. T\u00f5si, Poweri indikaatori asemel ilmus USB indikaator, kuid siin ei saanud midagi teha. Tuleb m\u00e4rkida, et modemi juures ei olnud nuppu reset v\u00f5i midagi sarnast, nii et kui seade 'hangus', tuli USB v\u00e4lja l\u00fclitada ja seade uuesti \u00fchendada. Sellegipoolest juhtus hangumist harva.<\/p>\n

Modem \u00fchendas telefoniliini t\u00e4iesti tavalisel viisil, nagu iga dialup-kasutaja ootaks.<\/p>\n

Tarkvara oli k\u00f5rgel tasemel. Komplekti kuulus isegi v\u00e4ga tuntud programm VentaVoice vene liidesega. Seade suutis probleemideta imiteerida t\u00f5eliste AON-id ja fakse, ning k\u00f5ik t\u00f6\u00f6tas t\u00f5rgeteta.<\/p>\n

\u00dchendus seadistati v\u00e4ga kiiresti, signaal \"liin on h\u00f5 ocupied\" t\u00f6\u00f6tati praktiliselt alati \u00f5igesti. Kui \u00fchendus saavutati, pidas modem seda mitu tundi umbes sama kiirusel.<\/p>\n

Acorp 56EMS<\/h3>\n

\n\"Eelk\u00e4ijad
\n
\nAcorp modemeid ei tohi mingil juhul unustada, kui me ei soovi j\u00e4tta t\u00e4helepanuta olulist osa modemite ajaloost. Selle tootja seadmed on alati olnud stiilsed ja eristunud sarnastest.<\/p>\n

Acorp 56EMS \u00fchendati COM-pordiga. See on varustatud k\u00f5ikide vajalike indikaatoritega, tagapoole olid portid mikrofoni ja k\u00f5rvaklappide \u00fchendamiseks, pluss kaks telefonipordi. Modemi alus on Rockwelli kiip. Oli v\u00f5imalus tarkvara uuendada Flash ROM-i olemasolu t\u00f5ttu.<\/p>\n

Seade on koosk\u00f5las K56Flex standardiga, just t\u00e4nu sellele suutis see t\u00f6\u00f6tada kiirusel kuni 56k.<\/p>\n

T\u00f5epoolest, need modemid said kodumaiste telefoniv\u00f5rkude m\u00f5ju, ja \u00fcsna m\u00e4rkimisv\u00e4\u00e4rselt. Lubatud kiirus oli saavutatav, kuid see juhtus harva. Oli probleeme \u00fchendusega, mis ei olnud alati stabiilne.<\/p>\n

Kuid Acorp modemid olid oluliselt odavamad kui teised legendaarsete seadmete seas, seega olid nad t\u00f5eliselt levinud. Sellegipoolest t\u00f6\u00f6tasid seadmed vanadel liinidel suhteliselt h\u00e4sti.<\/p>\n

\nJa veel \u00fcks USB-modem, mis tuli turule juba dial-up'i ajastu l\u00f5pus. Muide, just siis hakkasid D-linki tooted populaarsust koguma, millel oli juba tol ajal siiski \u00e4ratuntav disain.<\/p>\n

Modem oli v\u00e4ike, tal oli vaid kaks indikaatorit \u2014 Power ja Link. Selle populaarsus seletati madala hinnaga. Probleemiks oli see, et seadmes puudus teine pesa telefonikaabli jaoks, mist\u00f5ttu tuli telefon \u00fchendada paralleelselt lisapesaga.<\/p>\n

Malest hoolimata hoidis see \u00fcsna stabiilselt \u00fchendust isegi k\u00f5ige vanematel liinidel. T\u00f5si, signaali \"h\u00f5ivatud\" t\u00f6\u00f6tleb modem mitte k\u00f5ige paremini, j\u00e4tkates sageli t\u00f6\u00f6d ka siis, kui kuuldavad tooni.<\/p>\n

Komplekti kuulus Classic Phone Toolsi tarkvara, mis v\u00f5imaldas modemit kasutada faksi jaoks. Programmi t\u00f6\u00f6 kohta ei olnud mingeid kaebusi.<\/p>\n

P\u00f5him\u00f5tteliselt on t\u00e4naseks k\u00f5ik \u2014 kui artikkel osutub n\u00f5utuks, avaldame ka teise osa. Kuid parem on, kui j\u00e4tate kommentaaridesse mudelid, mille j\u00e4rgi teid meenub. Nostalgitseme koos.<\/p>\n
