Conception et mise en oeuvre d'un systme de commutation tlphonique by Carlos Alberto Vargas Quiroz Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Un système de contrôle basé sur des microcontrôleurs a été développé pour un équipement de communication et de commutation de dix abonnés, en principe il y aura deux téléphones connectés, pouvant atteindre dix dans l'ensemble de l'équipement, également l'union de neuf autres équipements similaires permet une communication totale de cent abonnés, puisqu'il y a deux chiffres pour un système de commutation complet. Pour la réalisation du projet, nous avons d'abord étudié et analysé tous les circuits présents dans un système de commutation général ou un central téléphonique, définissant ainsi les circuits de base présents dans le nouvel équipement de commutation. Ensuite, ces circuits ont été analysés et la possibilité de les relier aux microcontrôleurs a été étudiée. Une fois que cela a été fait, l'interface entre les deux est réalisée de sorte que les circuits soient commandés par les microcontrôleurs. Avant la mise en oeuvre, une série de tests est effectuée sur les circuits du système afin de voir comment ils réagissent dans des cas extrêmes, finalement tous les circuits présents dans le nouveau système de commutation téléphonique sont définis.

  1. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  2. Leaving positive feedback because 1) item was packed well & arrived as described 2) seller did give partial refund when subsequent price dropped below org purchase price. 3) communication was quick However, there was a downside to this transaction -item listed as in-stock but ended up waiting nearly a month for them to get it from their distributer then ship it to me (bought June 29th, arrived around July 21). Auction said 12-15 days. Better clarity would have prevented lot of frustration

  3. The seller was very responsive and answered me on a timely matter. The product itself came in its packaging and was new, not used at all. The packaging was not beat up or anything, safely delivered to my mailbox. No mix ups and zero stress with delivery. The price for the product is completely understandable for the product. I really appreciate the seller and I am very happy to have purchased through this seller. Completely trustable!
