Este m\u00e9todo es la conmutaci\u00f3n de circuitos representado en el esquema de la figura 2.3, en la cual los rect\u00e1ngulos representan las centrales telef\u00f3nicas. <\/p>\n<p>En este esquema cada central presenta tres l\u00edneas entrantes y tres salientes. Al pasar una llamada por la central, se instaura un enlace f\u00edsico entre la l\u00ednea por la ingresa la llamada y una l\u00ednea 9 saliente, el cual se mantiene todo el tiempo que dure la llamada(Rodr\u00edguez, 2012)(Tanenbaum, 2003).<\/p>\n<p>Este es un ejemplo de c\u00f3mo se realiza una llamada telef\u00f3nica por la red p\u00fablica telef\u00f3nica:<\/p>\n<p>1. El abonado A toma el tel\u00e9fono y escucha un tono, esto le permite saber que tiene conexi\u00f3n con la oficina local de su portador telef\u00f3nico.<br \/>\n2. El abonado A marca el n\u00famero de la persona con quien desea hablar, en este caso el abonado B.<br \/>\n3. La llamada se enruta desde el proveedor local a la persona que se est\u00e1 llamando B.<br \/>\n4. Una conexi\u00f3n f\u00edsica se hace entre el tel\u00e9fono de A y el tel\u00e9fono de B.<br \/>\n5. El tel\u00e9fono de B suena y seguidamente este contesta la llamada.<br \/>\n6. La conexi\u00f3n abre el circuito.<br \/>\n7. Se habla por un periodo de tiempo, el circuito se mantiene durante toda la llamada.<br \/>\n8. Cuando cuelgan, se libera el enlace f\u00edsico. <\/p>\n<p>\n<div id=\"rev_slider_3_1_wrapper\" class=\"rev_slider_wrapper fullwidthbanner-container\" style=\"float:left;background-color:#E9E9E9;padding:0px;margin-left:0px;margin-right:0px;margin-top:0px;margin-bottom:0px;\">\n<!-- START REVOLUTION SLIDER 5.0.9 auto mode -->\n\t<div id=\"rev_slider_3_1\" class=\"rev_slider fullwidthabanner\" style=\"display:none;\" data-version=\"5.0.9\">\n<ul>\t<!-- SLIDE  -->\n\t<li data-index=\"rs-28\" data-transition=\"random\" data-slotamount=\"7\"  data-easein=\"default\" data-easeout=\"default\" data-masterspeed=\"300\"  data-thumb=\"\"  data-rotate=\"0\"  data-saveperformance=\"off\"  class=\"voipswitch videos subtitulos\" id=\"voipswitch videos subtitulos\" voipswitch videos subtitulos data-title=\"SubtitulosTexto\" data-description=\"\">\n\t\t<!-- MAIN IMAGE -->\n\t\t<img src=\"https:\/\/servervoip.com\/blog\/wp-content\/plugins\/revslider\/admin\/assets\/images\/dummy.png\"  alt=\"\"  width=\"879\" height=\"51\" data-lazyload=\"https:\/\/servervoip.com\/blog\/wp-content\/plugins\/revslider\/admin\/assets\/images\/transparent.png\" data-bgposition=\"center top\" data-bgfit=\"cover\" data-bgrepeat=\"no-repeat\" class=\"rev-slidebg\" data-no-retina>\n\t\t<!-- LAYERS -->\n\n\t\t<!-- LAYER NR. 1 -->\n\t\t<div class=\"tp-caption   tp-resizeme\" \n\t\t\t id=\"slide-28-layer-2\" \n\t\t\t data-x=\"\" \n\t\t\t data-y=\"1\" \n\t\t\t\t\t\tdata-width=\"['none','none','none','none']\"\n\t\t\tdata-height=\"['none','none','none','none']\"\n\t\t\tdata-transform_idle=\"o:1;\"\n \n\t\t\t data-transform_in=\"opacity:0;s:300;e:Power2.easeInOut;\" \n\t\t\t data-transform_out=\"opacity:0;s:300;s:300;\" \n\t\t\tdata-start=\"500\" \n\t\t\tdata-responsive_offset=\"on\" \n\n\t\t\t\n\t\t\tstyle=\"z-index: 5;\">\n\t\t\t\t<div class=\"rs-looped disabled\" ><img src=\"https:\/\/servervoip.com\/blog\/wp-content\/plugins\/revslider\/admin\/assets\/images\/dummy.png\" alt=\"\" data-ww=\"879\" data-hh=\"51\" data-lazyload=\"https:\/\/www.servervoip.com\/blog\/wp-content\/uploads\/2015\/10\/fondo-en-degradado-con-signod-copia.jpg\" data-no-retina> \n\t\t\t\t<\/div>\n\t\t<\/div>\n\n\t\t<!-- LAYER NR. 2 -->\n\t\t<div class=\"tp-caption mediumbgorange   tp-resizeme\" \n\t\t\t id=\"slide-28-layer-1\" \n\t\t\t data-x=\"6\" \n\t\t\t data-y=\"5\" \n\t\t\t\t\t\tdata-width=\"['653']\"\n\t\t\tdata-height=\"['41']\"\n\t\t\tdata-transform_idle=\"o:1;\"\n \n\t\t\t data-transform_in=\"opacity:0;s:300;e:Power3.easeInOut;\" \n\t\t\t data-transform_out=\"auto:auto;s:300;\" \n\t\t\tdata-start=\"500\" \n\t\t\tdata-splitin=\"none\" \n\t\t\tdata-splitout=\"none\" \n\t\t\tdata-responsive_offset=\"on\" \n\n\t\t\t\n\t\t\tstyle=\"z-index: 6;

\/>\n&nbsp;<\/p>\n<hr \/>\nEste modelo de la figura 2.3 es muy sencillo si se considera que algunos tramos de la ruta de cobre entre los dos aparatos telef\u00f3nicos de los abonados que se est\u00e1n comunicando, pueden ser enlaces de microondas donde se multiplexan muchas llamadas, pero la representaci\u00f3n fundamental es adecuada, es decir que al establecerse una llamada, se establece una ruta dedicada entre los dos extremos de la comunicaci\u00f3n y se mantendr\u00e1 hasta que concluya la llamada. Una caracter\u00edstica fundamental de la conmutaci\u00f3n de circuitos consiste en que se requiere constituir una ruta de un extremo a otro antes de transmitir cualquier informaci\u00f3n(Tanenbaum, 2003). <\/p>\n<p>El tiempo desde la marcaci\u00f3n en el tel\u00e9fono del n\u00famero al que se desea llamar hasta que el timbre empieza a sonar puede ascender a 10 segundos y a\u00fan m\u00e1s si se trata de llamadas de larga distancia o internacionales. En este lapso de tiempo, el sistema telef\u00f3nico determina una ruta de cobre, como puede verse en la figura 2.3(Tanenbaum, 2003). <\/p>\n<p>Antes de iniciar el env\u00edo de informaci\u00f3n, la se\u00f1al de solicitud de llamada se transmite hasta el destino y este confirma su recepci\u00f3n. Al constar una ruta de cobre entre los abonados en comunicaci\u00f3n, luego del establecimiento de la llamada, solo se tiene el retardo de la informaci\u00f3n correspondiente al tiempo de transmisi\u00f3n de la onda electromagn\u00e9tica, esto es aproximadamente 5 mseg por cada 1000 km. El establecer una ruta dedicada evita la posibilidad de congesti\u00f3n, por lo tanto una vez que la llamada ingresa, no es posible tener un tono de ocupado, pero este podr\u00eda ocurrir antes de establecer el enlace por la falta de capacidad en la central o en los cables(Tanenbaum, 2003).<\/p>\n<p>Tomado de:<br \/>\n[1] V.
