مثل اینکه کسی نیست راهنمایی کنه و خودم باید مشکل رو حل کنم .
ببینید اطلاعاتی که راجع به Annex A و Annex B هست اینه ، البته به انگلیسی :
ITU standards often includes annexes that define how xDSL works under various conditions. ADSL, or G.992.1, also include annexes. The most commom annexes are
Annex A - ADSL over POTS. This is the basic ADSL among all other ADSL infrastructure, as we discussed in the previous sections. It is most common in north america, but also in many other places around the globe
Annex B - ADSL over ISDN. Most common in Europe. Places who already have ISDN infrastructure installed, or anybody who wants to enjoy the benefits ISDN capabilities offer in the LAN/telephony system (integrated services ,multiple user channels in a single line, high quality telephony capabilities) , but also connect the LAN to the internet, can choose this configuration. This way, ADSL Complements ISDN on the Last Mile
The implementation is done using frequencies seperators called "splitters", which combines both services at the CO and then split them back at the customer premises
خوب الان خطوط ما ADSL over POTS یا ADSL over ISDN ؟
