[ROUTERS] gran problema con router cisco 2600!!!!!

hola q tal????


tengo un gran problema con un router cisco 2600, el router este tiene dos enlaces t1 en los seriales (uno en cada uno) y en el fastethernet tiene conectada la lan.

bueno, el problema es el siguiente. cuando tengo los dos seriales levantados la velocidad de coneccion es de 100 kb!!!!! cuando tendria q tener 3 Mb!!!, ahora..... si le hago shutdown a una serial(no importa cual) hago un testeo de velocidad y la velocidad sube a 1.5 mb (la velocidad real de una T1). por favor ayudenme con esto q me esta volviendo locooooo
aqui les dejo el running config (con las ip en "x" por supuesto.... ) muchas gracias!!!!!!!
