Modulation Protocols/v.standards

Модуляци хийх протокол нь модем өгөгдлийг телефон шугман дээгүүр дамжуулахдаа яаж тоон сигналаас аналог руу хувиргах вэ гэдгийг тодорхойлж өгдөг.


Хамгийн анхны модуляцийн протокол нь Bell 103 болон ү.21 байсан ба эдгээр нь өгөгдлийг 300 bps хурдаар дамжуулдаг байв. Нэг битийг нэг сигнал руу хувиргаснаар 600 bps-с илүү хурдаар өгөгдөл дамжуулах боломжгүй байв. Тоон өгөгдлийг бусад сигналуудтай нийлүүлж хувиргаснаар өндөр хурдаар өгөгдөл дамжуулах боломжтой болсон. Эдгээр нь ү.32bis, ү.34 зэрэг протоколууд юм. "bis" болон "ter" нь тухайн протоколын хоёрдахь болон гуравдахь хувилбар юм. Жишээ нь: ү.32 нь 9600bps бол ү.32bis нь 14400 bps, үүний дараагийн хувилбар болох ү.32terbo нь 19200 bps-н хурдтай.

ITU буюу олон улсын цахилгаан холбооны эвслээс гаргасан модемын ү стандартууд:

v.22    1200 bps
v.22 bis    2400 bps
v.32     4800bps, 9600 bps
v.32bis     14400 bps
v.32terbo    19200 bps
v.34     28800 bps
v.34bis     33600 bps
v.35     Сүлжээний төхөөрөмжинд хэрэглэгддэг коннектор
v.42     ү.32, ү.32bis-тэй ижил хурдтай боловч алдаа засах боломжтой
v.90     56Kpbs
