Abstract

L'invention concerne un procédé et un dispositif de réduction du délai total du trafic MTA dans un réseau de communication dans lequel plusieurs noeuds (2-4) partagent un support physique multiplexeur temporel commun (5) pour la transmission des cellules MTA dans une direction de liaison montante (6). Les noeuds (2-4) comprennent un émulateur de circuit (11) dans lequel les cellules MTA à transmettre sont mises en paquets, et un terminal réseau (8) comprenant au moins une boucle PLL (27), un détecteur de phase (26) et, de préférence, une unité fondée sur le délai de phase (24). La fréquence nominale des créneaux temporels alloués au support physique (5) est identique à la fréquence de génération des cellules MTA. En utilisant les composantes susmentionnées, la génération de cellules MTA sera verrouillée en fréquence et en phase aux créneaux temporels alloués afin de réduire le temps d'attente dans le tampon (26) du noeud.
