A portable radio (104) initiates a communication link using a synchronous protocol format. A base station (102) generates a synchronization pattern (200) which includes a marker. The marker (202) includes a generic code that invites portables to make link requests. The portable radio (104) synchronizes to the marker (202) and recognizes the generic code that indicates base availability. The portable radio (104) sends a link request in response to the generic code to initiate the communication link, and the base station (102) grants a link in order to establish the communication link.

Une station de base (102) génère un schéma de synchronisation (200) qui comprend un marqueur. Le marqueur (202) comprend un code générique qui invite les postes portatifs à présenter des demandes de liaison. Le poste radio portatif (104) se synchronise sur le marqueur (202) et reconnaît le code générique qui indique la disponibilité de la base. Le poste radio portatif (104) envoie une demande de liaison en réponse au code générique pour amorcer la liaison de communication, et la station de base (102) accorde une liaison pour l'établissement de la liaison de communication.
